New Jersey v. New York et al No. 5 Original, October Term 1950

Dear Sirs and Madam:

For the record and in compliance with the provisions of the Amended Decree of the Supreme Court of the United States entered June 7, 1954,1 am transmitting herewith the fortieth Annual Report of the River Master of the Delaware River for the year Decem­ ber 1,1992, to November 30, 1993.

Monthly precipitation in the upper Delaware River basin during the 1993 River Master report year ranged from 33 percent of the long-term (52-year) average during May to 165 percent during April. Total precipitation during the year was 0.05 inches below average. Precipitation during the December to May period, when reservoirs typically refill, was 103 percent of the average.

On December 1, 1992, when this report year began, combined storage in the New York City reservoirs in the upper Delaware River Basin was 177.521 billion gallons (Bgal), which is 65.5 percent of the combined storage capacity. Median storage on December 1, based on 25 years of data, is 161.018 Bgal. Operations on December 1,1992 were being conducted as prescribed in the Decree. Storage in the New York City Delaware River Basin reservoirs increased to capacity by mid-April and all three reservoirs spilled.

Precipitation during May was extremely low, 33 percent of the long-term average, and caused the seasonal drawdown to begin approximately one month earlier than normal. By June 1, 1993, storage was below normal and remained below normal until the end of the report year. Precipitation continued to be below normal through August with the pre­ cipitation deficit during the May to August period accumulating to almost seven inches.

The Delaware River Master Advisory Committee met at Port Jervis, New York on May 25, 1993, to discuss hydrologic conditions in the basin and operational procedures for the 1993 release season. The Acting River Master informed the committee that, on the basis of information provided by New York City, the excess quantity to be released begin­ ning June 15 was 7.381 Bgal. He stated that based on the formula contained in the Decree, this water would be released at rates designed to maintain the Montague target flow at 100ft3/s above the normal 1,750 ft3/s beginning June 15, 1993. The Parties to the Decree agreed that conditions were somewhat below normal but that the excess-release quantity should be released as prescribed by the Decree.

On June 23, 1993, the Parties to the Decree, the Delaware River Basin Commis­ sion (DRBC), and the Acting River Master unanimously agreed to a request by New York State for a change in the augmented conservation release program from Pepacton and Neversink Reservoirs. Details of the three-year experimental program are included in sec­ tion n of this report and a copy of the agreement is attached as Appendix A.

Combined storage in the New York City Delaware River Basin Reservoirs declined at above normal rates throughout the summer in response to below normal pre­ cipitation and above normal releases to meet the Montague target. On August 4, 1993, the Parties to the Decree, the Delaware River Basin Commission, and the Acting Delaware River Master agreed to suspend the release of the remainder of the excess-release quantity per the procedures contained in the Lower Basin drought plan (DRBC Resolution 88-22 Revised) in an effort to prevent, or at least delay, the entry into drought warning in the basin. In spite of this action, storage continued to decline and reached the drought-warning level of the operating curves on September 16, 1993. Operations were reduced to those prescribed for drought warning on September 21, 1993 and remained at that level until the end of the report year. Details of the operations are described in section n of this report.

On November 30, 1993, the end of this report year, the combined storage in the New York City reservoirs was 123.472 Bgal, 45.6 percent of capacity, and the operations in the basin were being conducted as prescribed in the "Interstate Water Management Rec­ ommendation of the Parties to the Decree" (DRBC Resolution No. 83-13).

During the report year, the Acting River Master and staff participated in meetings of the Delaware River Basin Commission to assess water-supply conditions. Upon invita­ tion of the representatives of the Parties to the Decree, the Deputy Delaware River Master met periodically with those representatives as a member of the Flow Management Techni­ cal Advisory Committee. Discussions primarily centered on proposals for the manage­ ment of releases from reservoirs in the basin and other measures designed to cope with streamflow deficiencies whenever they occur.

The U.S. Geological Survey continued the operation of its field office of the Dela­ ware River Master at Milford, Pennsylvania. William E. Harkness, Deputy Delaware River Master, continued in charge of the office, assisted by Bruce E. Krejmas and Beverly A. Roberts. Upon the retirement of Mr. Stanley P. Sauer in March 1993, Mr. Harkness was designated Acting Delaware River Master. William J. Carswell, Jr., the USGS Regional Hydrologist at Reston, Virginia, was designated the Delaware River Master effective May 1,1995.

During the report year, the Milford office continued the weekly distribution of summary river data. These weekly reports contained preliminary data on releases from the New York City reservoirs to the Delaware River, diversions to the New York City water- supply system, reservoir contents, daily segregation of flow of the Delaware River at Montague gaging station, and diversions by New Jersey. The reports were made available to the State and City representatives on the Delaware River Master Advisory Committee and to other parties interested in the Delaware River operations. A special monthly sum­ mary of past hydrologic conditions, supplemented by an "outlook" of the river flow for the forthcoming month, was made available to the representatives on the Advisory Commit­ tee.

Section H of this report describes in detail Delaware River operations during the report year. As shown on page 16, the City of New York diverted a total of 246.250 Bgal from the basin during the report year ending November 30, 1993 and released 100.345 Bgal from Pepacton, Cannonsville, and Neversink Reservoirs to the Delaware River dur­ ing the same period. The River Master directed releases to the Delaware River from these reservoirs totaling 77.368 Bgal.

Section ni of this report describes water quality at various sites in the Delaware River Estuary. It was prepared by Charles R. Wood, U.S. Geological Survey, Malvern, Pennsylvania and contains data showing the extent of salinity encroachment and other water-quality characteristics in the estuary.

During the report year, the following individuals served as members of the River Master Advisory Committee:

Delaware Dr. Robert R. Jordan

New Jersey Steven Nieswand

New York Russell C. Mt Pleasant Daniel J. Campbell

New York City Albert F. Appleton

Pennsylvania John E. McSparran William A. Gast

Throughout the year, diversions to supply water for New York City and releases designed to maintain the flow of the Delaware River at Montague were made as directed by this office. Diversions by New York City from the Delaware River basin reservoirs did not exceed the limit specified by the Decree or the limits in the several agreements among the Parties to the Decree.

The appreciation of the River Master and staff is expressed for the continued excellent cooperation of all the representatives of the Parties to the Decree. Appreciation also is extended to the Pennsylvania Power & Light Company and the Orange and Rock- land Utilities, Inc. for keeping us informed of their plans for power generation and result­ ing releases.

A draft of this report was furnished to the Advisory Committee members for com­ ment

Sincerely yours,

William J. Gfrswell, Jr., Ph.] Delaware^civer Master

REPORT OF DELAWARE RIVER OPERATIONS

by William E. Harkness and Bruce E. Krejmas

ABSTRACTA Decree of the Supreme Court of the United States in 1954 established the position of

Delaware River Master. The Decree authorizes diversions of water from the Delaware River Basin (fig. 1) and requires compensating releases from certain New York City owned reservoirs to be made under the supervision and direction of the River Master. Reports to the Court, not less frequently than annually, were stipulated.

During the 1993 report year, December 1, 1992, to November 30, 1993, the monthly pre­ cipitation and runoff in the Delaware River Basin ranged from above average to below average. For the year as a whole, precipitation was 0.05 inches below average. Reservoir storage in the basin increased seasonally from December 1, 1992 through January 1993, decreased during Feb­ ruary and March, then increased to capacity during April. Storage declined steadily from May 1 to October 31, 1993, reaching drought-warning level September 16, 1993. Operations were con­ ducted at reduced levels designed to conserve the short water supplies caused by the drought- warning conditions in the basin from September 21 to November 30, 1993.

Diversions from the Delaware River basin by New York City and New Jersey did not exceed those authorized by the terms of the Amended Decree, or the reduced limits imposed because of the drought. Releases were made as directed by the River Master at rates designed to meet the Montague flow objective on 144 days during the year. Releases were made at the aug­ mented conservation rates, at rates designed to relieve thermal stress and protect the fishery in the streams downstream from the reservoirs, or at other times at the basic conservation rates.

New York City and New Jersey complied fully with the terms of the Decree, the agree­ ments reached to conserve water in the basin during the drought, and with the directives of the River Master during the year.

INTRODUCTION

The Amended Decree of the United States Supreme Court entered June 7, 1954, autho­ rized diversions of water from the Delaware River Basin and provided for releases of water from certain New York City reservoirs to the Delaware River to be made under the supervision and direction of the River Master. The Decree also stipulated that reports be made to the Court not less frequently than annually. This report describes the River Master operations from December 1, 1992 to November 30,1993.

Part of the hydrologic data presented are records of flow and water quality at U.S. Geolog­ ical Survey gaging stations. These records were collected, computed, and furnished by the Offices of the U.S. Geological Survey at Albany, New York, Malvern, Pennsylvania, and West Trenton, New Jersey, in cooperation with the States of New York and New Jersey, the Commonwealth of Pennsylvania, and the City of New York.

Definition of Terms and ProceduresThe following definitions apply to various terms and procedures used in the operations

described in this report. A table for converting inch-pound units to International System of Units (SI) is given on page v. The map of the Delaware River Basin (fig. 1) indicates the location of per­ tinent streams, reservoirs, and gaging stations.

Time of day. - Time of day is expressed in 24-hour eastern standard time, which included a 23-hour day April 4 and a 25-hour day October 31.

Rate of flow. - Mean discharge for any stated 24-hour period, in cubic feet per second (ftVs) or million gallons per day(Mgal/d).

Rate of flow at Montague. - Daily mean discharge of the Delaware River at Montague, N.J., on a calendar-day basis.

Reservoir-controlled releases. - Controlled releases from reservoirs passed through outlet valves in the dams or through turbines in powerplants. This does not include spillway overflow at the reservoirs.

Conservation releases. - Controlled releases from reservoirs designated to maintain flow in the channels downstream from the reservoirs.

Directed releases. - Controlled releases from the New York City Reservoirs in the upper Delaware River Basin designed by the Delaware River Master to meet the Montague flow objec­ tive.

Uncontrolled runoff at Montague. - Runoff from the drainage area upstream from Mon­ tague exclusive of the drainage area upstream from the Downsville, Cannonsville, Neversink, Wallenpaupack, and Rio dams but including spillway overflow at these dams.

Point of maximum reservoir depletion. - Elevation at the top of the highest outlet, some­ times referred to as minimum full-operation level.

Storage or contents. - Usable volume of water in a reservoir. Unless otherwise indicated, volume is computed on the basis of level pool and above the point of maximum depletion.

10

Capacity. - Total usable volume between the point of maximum depletion and the eleva­ tion of the lowest crest of the spillway.

Diversions. - The transfer of water by New York City from Pepacton, Cannonsville, and Neversink Reservoirs in the upper Delaware River Basin through the East Delaware, West Dela­ ware, and Neversink Tunnels, respectively, to its water-supply system. Also, the transfer of water by New Jersey from the Delaware River through the Delaware and Raritan Canal.

Excess quantity and seasonal period for its release. - As defined in the Decree, the excess quantity of water equals 83 percent of the amount by which the estimated consumption in New York City during the year is less than the City's estimate of continuous safe yield (1,665 Mgal/d stipulated by 1954 Decree) from all its sources of supply obtainable without pumping, except that the excess quantity should not exceed 70 billion gallons. Each year the "seasonal period" for release of the excess quantity begins on June 15. The design rate for that period becomes effective at Montague on that date and continues in effect until the following March 15, or until the cumu­ lative total of excess-release credits becomes equal to the seasonal quantity, whichever occurs first.

Daily excess-release credits. - Daily credits and deficits during the seasonal period are equal to the algebraic difference between the daily mean discharge at Montague and 1,750 ft3/s; however, the daily credit cannot exceed the 24-hour period releases from Pepacton, Cannonsville, and Neversink Reservoirs routed to Montague and made in accordance with direction, with the following exception. During the seasonal period, credits are also made for part or all of other releases from these reservoirs contributing to daily mean discharge at Montague between the excess-release rate and 1,750 ftVs.

PrecipitationPrecipitation measured in the basin above Montague totaled 43.03 inches for the 1993

report year and was 0.05 inches below the long-term (52-year) average (table I). 1 Monthly pre­ cipitation ranged from 33 percent of the long-term average in May, 1993 to 165 percent of the average in April, 1993. Table 1 compares the monthly precipitation during the report year with the long-term average.

These data were computed from records collected by the National Weather Service, New York City Department of Environmental Protection, Bureau of Water Supply and the River Mas­ ter, at 10 stations distributed over the basin area upstream from Montague.

December to May is generally considered the normal time of year when surface- and ground-water reservoirs fill. During this period in 1992-93, average precipitation at the 10 stations was 20.76 inches, which was 103 percent of the long-term average. During June to November, average precipitation at the 10 stations was 22.27 inches, which was 97 percent of the long-term average. The maximum monthly precipitation measured at the 10 stations was 7.46 inches in Sep­ tember at Cadosia, New York; the minimum monthly precipitation was 0.93 inches in May at Mil- ford, Pennsylvania.

AcknowledgmentsThe River Master daily operation records were prepared by the Milford Office of the Del­

aware River Master from hydrologic data collected principally on a day-to-day basis. Data for these records were collected and computed by the Milford office or were furnished by agencies as follows: Data from Pepacton, Cannonsville, and Neversink Reservoirs by the New York City Department of Environmental Protection, Bureau of Water Supply; from Delaware and Raritan Canal by the New Jersey Water Supply Authority; from Lake Wallenpaupack by the Pennsylvania Power & Light Company; and from Rio Reservoir by Orange and Rockland Utilities, Inc. Precip­ itation data and quantitative precipitation forecasts were provided by the National Oceanic and Atmospheric Administration, National Weather Service.

OPERATIONS

December through MayOperations on December 1, 1992 were being conducted as prescribed in the Decree. The

Montague flow objective was 1,860 ft3/s and the allowable diversions to New York City and New Jersey were 800 Mgal/d and 100 Mgal/d respectively. Conservation releases from New York City reservoirs were being made at the augmented levels shown in table 2.

During the first half of the report year, total precipitation was 0.59 inches above average and monthly precipitation ranged from 165 percent of the long-term average in April to 33 per­ cent in May (table 1). Runoff in the Upper Delaware River Basin was above normal during Janu­ ary and April, below normal during February and May, and within the normal range during December and March.

On December 1, 1992, Pepacton Reservoir contained 85.767 Bgal of water in storage above the point of maximum depletion, or 61.2 percent of the reservoir's storage capacity of 140.190 Bgal. Cannonsville Reservoir contained 69.331 Bgal, or 72.4 percent of the reservoir's storage capacity of 95.706 Bgal and Neversink Reservoir contained 22.423 Bgal, or 64.2 percent of the reservoir's storage capacity of 34.941 Bgal. The combined storage in the three reservoirs as of December 1 was 177.521 Bgal, or 65.5 percent of their combined capacity. Daily storages in Pepacton, Cannonsville, and Neversink Reservoirs are shown in tables 3, 4, and 5 respectively, and the combined storage is shown graphically in figure 2.

Inflow to the City's reservoirs during the December through May period generally exceeds draft rates and therefore increases storage. The average inflow to Pepacton, Cannonsville, and Neversink Reservoirs for these six months during the 52-year period, December 1940 to May 1992, was 299.0 Bgal. During the corresponding six months of the current report year, inflow to the three reservoirs totaled 358.9 Bgal. Evaporation loss was not included in the computation.

Combined storage held relatively steady during December 1992, increased seasonally dur­ ing January 1993, then declined gradually during February and most of March. During the last week of March and the first two weeks of April, storage increased rapidly in response to approxi­ mately 2.5 inches of precipitation and increased temperatures which served to melt the snowpack and created significant runoff.

Total storage in the three New York City reservoirs was 176.784 Bgal on November 30, 1992 and 258.750 Bgal on May 31, 1993. The maximum storage was 279.761 Bgal on April 12 (fig. 2) when all three reservoirs were spilling. Normally, maximum storage in the individual res­ ervoirs occurs on different days. The maximum storage in Pepacton Reservoir was 143.275 Bgal on April 17,1993, the maximum storage in Cannonsville Reservoir was 104.180 Bgal on April 2, 1993, and the maximum storage in Neversink Reservoir was 35.778 Bgal on April 17,1993. Dur­ ing the December to May period, diversions to Rondout Reservoir by New York City totaled 111.324 Bgal (612 Mgal/d). The forecast discharge at Montague, exclusive of water released from the City reservoirs, fell below the design rate on 11 days, 6 days during March and 5 days during May, and releases were directed. The observed discharge at Montague fell below the design rate on three days during March and two days during May. The release of a total of 4,091 (ft3/s)-d (2.64 Bgal) of water was directed during the period. New York City made releases for conserva­ tion purposes at the augmented conservation rates shown in table 2 on all other days during the period.

13

June through NovemberMonthly precipitation during the June through November period was below average in

June, July and August and was above average in September, October and November. Total precip­ itation during the period was 22.27 inches or 0.14 inches less than the 52-year average of 22.91 inches (table 1). Runoff in the Upper Delaware River Basin was below normal in June, July and August, within the normal range in September and October, and above normal in November.

The New York City Department of Environmental Protection, Bureau of Water Supply, furnished the River Master with the following advance data for the 1993 calendar year:

1. The estimated continuous safe yield from all the City's sources, obtainable without pumping, is 1,665 Mgal/d, or a total during the calendar year 1993 of 1.665 Bgal/d x 365 days = 607.725 Bgal.

2. The estimated consumption that the City must provide from all its sources of supply during calendar year 1993 is 591.582 + 7.250 = 598.832 Bgal.

On the basis of the provisions of the Decree and the above data, the aggregate quantity of excess-release water was 83 percent of (607.725 - 598.832) or 7.381 Bgal. The Montague design rate during the excess release period beginning June 15,1993, was computed as:

1.750flfr+ 7.381 Bgal xl 547 (ft3/s)/(Bgal/d)120 days

Data on consumption of water by the City of New York for each calendar year, since 1950, are shown in table 6.

Releases were directed to satisfy the Montague design rate on 133 days between June 1 and November 30,1993, when the forecasted discharge at Montague, exclusive of water released from the New York City reservoirs, fell below the applicable design rate (table 7). Releases at var­ ious conservation rates or at rates designed to protect the fishery were made at other times from each reservoir from June 1 to November 30. A total of 1,639 (ft3/s)-d (1.059 Bgal) was released for the relief of thermal stress from June 8 through July 15.

From June 1 to June 14, the level of flow required to be maintained in the Delaware River at Montague was 1,750 ft3/s. The forecasted flow, exclusive of releases from Pepacton, Cannons- ville, and Neversink Reservoirs, was less than the design rate on ten days during the period and releases were directed.

At the Delaware River Master Advisory Committee meeting on May 25, 1993, New York State proposed a change in the augmented conservation release schedules for Pepacton and Nev­ ersink Reservoirs. The Parties to the Decree unanimously agreed to the proposal for a three-year experimental period. The experimental release rates listed in table 2 were approved by the Dela-

14

ware River Basin Commission, Docket No. D-77-20 CP (Revision No. 2), on June 23, 1993 and were put into effect June 24, 1993. A copy of the docket and the agreement are attached to this report as Appendix A.

On June 15, 1993 the seasonal period for the release of the excess quantity began and the Montague design rate was increased to 1,850 ft3/s. Between June 15 and August 4, in response to below normal runoff from precipitation and above normal releases to meet the Montague design rate, the storage in the New York City reservoirs declined rapidly. On August 4, 1993, in an effort to prevent or at least delay entry into drought warning, the Parties to the Decree met at Malvern, Pennsylvania and unanimously agreed to set aside the remainder of the excess-release quantity based on procedures contained in the lower basin drought plan, DRBC Resolution No. 88-22 (Revised). The Acting River Master concurred and the Montague design rate was returned to 1,750 ftVs effective August 8, 1993. A total of 3.418 Bgal of the 7.381 Bgal excess-release quan­ tity was released and the remainder, 3.963 Bgal, was put in a bank to be used if needed to meet the Trenton target at a later date.

Throughout August and September, precipitation continued to be significantly below nor­ mal, the releases required to meet the Montague design rate were very high, and storage continued to decline at above normal rates. Combined storage declined below the drought-warning level of the operation curves on September 16,1993 and remained below that level for five days. On Sep­ tember 21,1993 the Montague design rate was reduced to 1,655 ft3/s and the allowable diversions to New York City and New Jersey were reduced to 680 Mgal/d and 85 Mgal/d respectively, as required by the "Interstate Water Management Recommendations of the Parties to the Decree" (DRBC Resolution 83-13).

On September 22, 1993, the Parties to the Decree, the DRBC and the Delaware River Master met pursuant to DRBC Resolution No. 83-13, to consider a request by New York State for an emergency fisheries protection program designed to allow special releases from the New York City Delaware River Basin reservoirs to protect the fishery during the drought-warning period. The Parties to the Decree unanimously agreed to allow New York State to request special releases totaling a maximum of 3,000 ft3/s-d and requiring that the amount released be paid back via reductions in the releases required to meet the Montague target. A copy of the agreement is attached to this report as Appendix B. A total of 1,496 ft^/s-d was released to protect the fishery and 1,111 ft3/s-d was paid back via reductions in releases to meet the Montague flow objective between September 28 and November 30,1993. The special releases and the reductions in release requirements are summarized in table 8.

Between June 15, when release of the excess quantity began, and November 30,1993, the forecasted flow at Montague, exclusive of releases from the New York City reservoirs, was below the design rate on 122 days and releases were directed. On 17 of the days that releases were directed, the directed release was less than the deficiency because of the payback of the emer­ gency fishery protection releases (table 8).

On 54 days during the June 15 to November 30 period, the observed flow fell below the design rate. Of those 54 days, 32 were within 10 percent of the design rate and 22 were more than 10 percent below the design rate.

The total discharge at Montague; the portion derived from uncontrolled runoff down­ stream from the reservoirs; the portion contributed by the power reservoirs; and the portion con­ tributed by Pepacton, Cannonsville, and Neversink Reservoirs are shown by the hydrographs in figure 3. In analyzing the water budget at Montague, the uncontrolled runoff downstream from the reservoirs was computed as the residual of observed flow less releases from all reservoirs and therefore was subject to all the errors in observations, transit times, and routing of the several components of flow. All of these uncertainties are contained in the computed hydrograph of uncontrolled runoff.

Diversions to Rondout Reservoir June 1 to November 30 totaled 134.926 Bgal.

Summary of OperationsFrom December 1, 1992, to November 30, 1993, diversions to Rondout Reservoir totaled

246.250 Bgal, and all releases from the New York City reservoirs to the Delaware River totaled 100.345 Bgal.

During the year, maximum storage in Pepacton Reservoir was 143.275 Bgal, on April 17, 1993. Maximum storage in Cannonsville Reservoir was 104.180 Bgal, on April 2. Maximum stor­ age in Neversink Reservoir was 35.778 Bgal, on April 17. The maximum combined storage in the three reservoirs during the year was 279.761 Bgal, on April 12, when all three reservoirs were spilling.

Minimum combined storage in the reservoirs during the year was 94.189 Bgal on October 31, 1993. Minimum storage in Pepacton Reservoir was 63.330 Bgal (45.2 percent of capacity) on November 14, 1993. Minimum storage in Cannonsville Reservoir was 19.310 Bgal (20.2 percent of capacity) on September 26,1993 and minimum storage in Neversink Reservoir was 7.496 Bgal (21.5 percent of capacity) on November 27,1993.

On November 30, 1993, combined storage in the three reservoirs was 123.472 Bgal, or 45.6 percent of their combined capacity. During the year, combined storage decreased 53.312 Bgal, or 19.7 percent of capacity.

The combined storage of the three reservoirs on the first day of the month from June 1967 to November 1993 is shown in figure 4. Storage was below the median all months except Decem­ ber, February, March and May and was below the 25th percentile June through November.

SUPPLEMENTARY RELEASE FROM WALLENPAUPACK POWERPLANT

An agreement between Pennsylvania Power & Light Company and New York City pro­ vides for supplementary releases from Wallenpaupack hydroelectric powerplant if the Delaware River Basin Commission requests compensation for water consumed at the company's Martins Creek steam-electric generating station. Releases may be requested if the flow of the Delaware River at Trenton, N.J. is expected to be less than 3,000 ft3/s for more than three consecutive days. No supplementary releases were requested during the year.

COMPONENTS OF FLOW, DELAWARE RIVER AT MONTAGUE, N.J.

The data and computations of the various components of flow formed the basic opera­ tional records required to carry out the River Master's specific responsibilities with respect to the Montague Formula during the report year. The operational record has two parts: the forecasted flow at Montague, exclusive of controlled releases from New York City's reservoirs (table 9) and the segregation of the daily average flow at Montague among its various source components (table 10).

Discharge of the Delaware River at Montague was composed of the following source components:

1. Controlled releases from Lake Wallenpaupack on Wallenpaupack Creek in the production of hydroelectric power.

2. Controlled releases from Rio Reservoir on Mongaup River in the production of hydroelectric power.

3. Runoff from the uncontrolled area upstream from Montague.

4. Controlled releases from Pepacton, Cannonsville, and Neversink Reservoirs of New York City.

The releases from the City's reservoirs necessary to maintain the applicable rate of flow at Montague was computed from the forecasted flow at Montague, exclusive of controlled releases from the City's reservoirs.

19

TIME OF TRANSITThe average times for the effective transit of water from the various sources of controlled

supply to Montague used for discharge routing during the 1993 report year are as follows:

Source Hours

Pepacton Reservoir 60Cannonsville Reservoir 48Neversink Reservoir 33Lake Wallenpaupack 16Rio Reservoir 8

This schedule was developed from reservoir and powerplant operations and gaging-station records of prior years and was found generally suitable. At times, noticeable exceptions occur, for example, when a large release from Cannonsville Reservoir follows a small one, a large part of the release is expended in filling the channel en route, and the remainder may appear at Montague as much as 18 hours late. During the winter, ice cover, together with the low streamflow, gradu­ ally increases the resistance to streamflow and lengthens the time of transit. However, because the increased travel time generally occurs gradually over several days and releases were not generally being directed to meet the Montague flow objective during that time, no adjustments were made to compensate for the increased travel time under ice cover.

SEGREGATION OF FLOW AT MONTAGUE

The River Master daily operation record of reservoir releases and daily segregation of flow among the various source components contributing to the flow of the Delaware River at Montague is shown in table 10. The arrangement of data conforms with the downstream move­ ment of water from the various sources to Montague. A horizontal summation of data in the table is equivalent to routing the various contributions to Montague, using the schedule for travel time of water discussed previously. The uncontrolled runoff was computed by subtracting the contribu­ tions of the several other sources from the observed discharge at Montague.

COMPUTATION OF DIRECTED RELEASES

In the daily operations, it was necessary to utilize: (1) discharges computed from recorded or reported stream gage heights for various 24-hour periods without current information about changes in stage-discharge relations that might have occurred; (2) daily discharge from New York City's three reservoirs obtained from venturi meters; (3) rainfall reports for the previous 24 hours; (4) actual powerplant releases converted to daily discharge; (5) advance estimates of power demand converted to daily discharge; (6) advance estimates of uncontrolled runoff at Montague; and (7) average times for routing of water from the several sources. Variable errors of estimate occur in projecting data, but these data must be used in the daily design and direction of releases from the reservoirs.

20

The time of transit of water from Pepacton Reservoir to Montague (60 hours) was greater than the transit time of water from any other reservoir. Releases from Cannonsville and Neversink Reservoirs were timed to arrive at Montague concurrently with releases from Pepacton Reservoir. To allow for the actual differences in transit times, daily directed releases from Pepacton were scheduled to begin at 1200 hours, releases from Cannonsville were scheduled to begin at 2400 hours, and releases from Neversink were scheduled to begin at 1500 hours the following day.

Releases from the City's reservoirs required to maintain the specified flow at Montague were calculated after estimates of releases from Lake Wallenpaupack and Rio Reservoir were obtained and after a forecast was made of the uncontrolled runoff at Montague. Taking into account the time of transit from these sources to Montague, the calculation required that estimates of the following components be made two or more days in advance: (1) release of water from Lake Wallenpaupack, (2) release of water from Rio Reservoir, and (3) uncontrolled runoff at Montague. The River Master daily operation record for computing daily directed release from the City's reservoirs during the periods of low flow is shown in table 9.

The electric power companies cooperated fully in furnishing advance estimates of power- plant releases. As the hydroelectric plants were used chiefly for meeting peak-power demands of the system, advance estimates were subject to many modifying factors such as the influence of the vagaries of weather upon peak-power demand. In addition, the power companies are members of wide area power pools which may present unforeseen demands for power generation. As a result, the actual use of water for power generation was at times at considerable variance with the advance estimates that were used by the River Master's office in design computation.

For computation purposes during periods of low flow, the estimate of uncontrolled runoff at Montague was treated as two items: (1) current runoff and (2) estimated increase in runoff from precipitation. Estimated quantities for these items are shown in table 9.

During the winter period, the advance estimate of the uncontrolled runoff (current condi­ tions) was based on flows at nearby gaging stations and on the recession curve of the computed uncontrolled flow at Montague.

During ice-free conditions, the current runoff was calculated using a routing and recession procedure based on discharges as of 0800 hours at the gaging stations listed below:

Drainage area Station (nu'2)

Beaver Kill at Cooks Falls, N.Y.241Cadosia Creek at Cadosia, N.Y. 17.9Oquaga Creek at Deposit, N.Y. 67.6Equinunk Creek at Equinunk, Pa. 56.3Callicoon Creek at Callicoon, N.Y. 110Tenmile River at Tusten, N.Y. 45.6Lackawaxen River at Hawley, Pa. 290Shohola Creek near Shohola, Pa. 83.6Neversink River at Port Jervis, N.Y. 336

21

The forecasted increase in runoff from precipitation is shown in table 9 under the heading of "Weather Adjustment." The National Weather Service Office, Mt. Holly, N.J., cooperated throughout the low-flow periods by furnishing quantitative forecasts of average precipitation over the drainage area above Montague and air temperatures for each day of the three-day design period. During the winter, runoff was estimated from the current state of snow and ice and from forecasted temperature and precipitation. During other periods, the forecasted precipitation was used to calculate runoff.

The forecasted flow at Montague, exclusive of releases from the City's reservoirs, was the sum of the forecasted releases from the power reservoirs, the estimated uncontrolled runoff under then current conditions, and the weather adjustment (table 9). If the computed flow was less than the desired flow at Montague, the expected deficiency was made up by corresponding releases from New York City reservoirs.

When revised forecasts of precipitation or powerplant releases became available, the releases required from the reservoirs were recomputed. Usually this procedure resulted in a reduced release requirement from New York City reservoirs for that day and therefore conserved water. Only the final figures are shown in table 9.

ANALYSIS OF FORECASTSForecasts of the flow at Montague based on the anticipated flow of the several components

(exclusive of the release from New York City's reservoirs) varied somewhat from the observed flow on most days. At times, variations in the several components are partially compensating and the resulting observed flows were fairly close to the estimated flows.

The forecasted flow of the Delaware River at Montague, exclusive of the releases from the New York City reservoirs, was less than the applicable design rate on most days from May 27 to October 22,1993. The following tabulation compares the advance estimates of the various contri­ butions to the flow at Montague to the observed operations during this period:

22

During the period, New York City released slightly more water than was directed, the power companies released 9.2 percent more water from Lake Wallenpaupack and 0.2 percent less water from Rio Reservoir than was forecast, and the observed runoff from the uncontrolled area was 7.8 percent more than the forecasted runoff.

On the basis of the observed discharges at Montague, exact forecasting of releases required from the City's reservoirs during the report year would have totaled 117,530 (ft3/s)-d. Directed releases totaled 119,703 (ft3/s)-d, or 1.8 percent more than for exact forecasting.

A comparison of the hydrographs of forecasted runoff and the actual runoff from the uncontrolled area (fig. 5), indicates that the forecasting procedures tended to underestimate runoff during high precipitation events but the forecasts were generally adequate. Adjustments were made when needed to compensate for errors in the forecast, but because of the travel time, the effect of the adjustments at Montague are not seen for several days.

Analysis of the precipitation forecasts indicate that the total precipitation forecasted for the three-day design period is often fairly accurate but the storm may occur either earlier or later in the period. The accuracy of the runoff forecasts are significantly affected by the timing of the precipitation events. In addition, if the storm track is somewhat different than was anticipated, the amount and timing of the runoff is significantly affected.

DIVERSIONS TO NEW YORK CITY WATER SUPPLY

The 1954 Amended Decree allows New York City to divert water from the Delaware River Basin at a rate not to exceed 800 Mgal/d. The Decree also specifies that the rate of diver­ sions will be computed as the aggregate total diversion beginning on June 1 of each year divided by the number of days elapsed since the previous May 31.

Diversions from Pepacton, Cannonsville, and Neversink Reservoirs to the New York City water-supply system (Rondout Reservoir) during the report year are shown in table 11. The table includes a running account of the average rates of the combined diversions from the reservoirs, computed as prescribed by the Decree or the "Interstate Water Management Recommendations of the Parties to the Decree (DRBC Resolution 83-13)." The tabulation below shows the allowable maximum diversion rates and the actual diversions during those periods.

During the year, a total of 246.250 Bgal of water was diverted to the New York City water supply system. The allowable diversion during the year was 294.318 Bgal.

Tables 3, 4, and 5 show storage in Pepacton, Cannonsville, and Neversink Reservoirs, respectively, above the "point of maximum depletion" or minimum full-operating level.

On December 1,1992, combined storage in the three reservoirs was 177.521 Bgal. As dis­ cussed earlier, storage increased seasonally during December and January, declined during Febru­ ary and March, and increased rapidly during April, reaching capacity, and all three reservoirs spilled. The maximum storage for the year occurred on April 12, 1993, when all three reservoirs were spilling (fig. 2).

The seasonal decline in storage began in early May, about one month earlier than normal, and continued at above normal rates, reaching drought-warning level on September 16. The mini­ mum combined storage was 94,189 Bgal on October 31, 1993. Storage began to recover during November, reaching 123,472 Bgal, 45.6 percent of capacity on November 30,1993.

COMPARISON OF RIVER MASTER OPERATION DATA AND OTHER STREAMFLOW RECORDS

It has been explained that the River Master operations are, in effect, day-to-day opera­ tions, for which it is necessary to use preliminary records of streamflow. The following summa­ ries show comparison of records used in the River Master operations and U.S. Geological Survey records. In the comparison of releases, the data used were reported in units of million gallons per day (Mgal/d) and converted to cubic feet per second (ft3/s) in the summaries.

25

Releases from New York City ReservoirsThe River Master operations data on the controlled releases from Pepacton, Cannonsville,

and Neversink Reservoirs, to the Delaware River were obtained from calibrated instruments con­ nected to venturi meters installed in the outlet conduits.

The U.S. Geological Survey gaging station on the East Branch Delaware River at Downs- ville, N.Y., is 0.5 mile downstream from Pepacton Reservoir dam (fig. 1). The discharge for this station (table 12) includes releases from Pepacton Reservoir and also includes a small amount of seepage and any runoff, which enters the channel between the dam and the gage site. The drain­ age area at the dam is 371 mi2 and at the gaging station is 372 mi2.

The tabulation below lists the comparison of the releases from Pepacton Reservoir reported by New York City to the final records for the USGS gaging station on the East Branch Delaware River at Downsville, N. Y. (table 12).

The differences are similar to the differences observed in previous years.

The U.S. Geological Survey gaging station on the West Branch Delaware River at Stiles- ville, N.Y. is 1.4 miles downstream from Cannonsville Dam (fig. 1). The discharge for this station (table 13) includes releases from Cannonsville Reservoir and the runoff from 2 mi2 of drainage area between the dam and the gage site. The drainage area at the dam is 454 mi2, and at the gaging station is 456 mi2.

The following tabulation compares the releases from Cannonsville Reservoir reported by New York City to the final records for the USGS gaging station on the West Branch Delaware River ar Stilesville, N.Y (table 13).

The gaging-station records are considered good above 100 ft3/s and fair below. The agreement between the data reported by New York City and the gaging station records is also good at high flows, but is only fair at low flows. The gaging-station records include the runoff from precipitation on the area between the dam and the gaging station and includes seepage that occurs near the base of the dam. On January 29, 1992, the seepage near the base of the dam was

26

measured and found to be 2.4 ft3/s. This value agrees with estimates made in previous years. If the gaging-station record is adjusted for seepage, the agreement at 22 ft3/s , 27 ft3/s , 34 ft3/s and 48 ft3/s from the above table becomes -5.7, -11.4, -9.5 and -1.2 percent respectively. We are con­ tinuing to monitor the differences and are working with New York City and the USGS field office to improve the agreement.

The U.S. Geological Survey gaging station on the Neversink River at Neversink, N.Y. is 1,650 feet downstream from Neversink Dam (fig. 1). The discharge for this station (table 14) includes releases from Neversink Reservoir and, during storms, a small amount of runoff which originates between the dam and the gage site. The drainage area at the dam is 92.5 mi2 and that at the gaging station is 92.6 mi2.

The following tabulation shows good agreement between releases from the Neversink Reservoir, computed form the venturi meter data, and the final discharge records for the USGS gaging station on the Neversink River at Neversink, N.Y., except for very low flows (table 14).

Releases from Lake WallenpaupackRecords of daily discharge through the Wallenpaupack powerplant were furnished by the

Pennsylvania Power & Light Company and published by the U.S. Geological Survey as Wallen­ paupack Creek at Wilsonville, Pa. (table 15). These discharges represent the flow through the tur­ bines of the powerplant and were computed on a midnight-to-midnight basis. For River Master operations, flows were computed on an 0800 hour to 0800 hour basis to compensate for the travel time to Montague (table 10).

From December 1992 through November 1993, the River Master's record agrees with the published U.S. Geological Survey record except for a slight variation due to the difference in the time frame and rounding of the computations.

Delaware River at Montague, N.J.

The River Master's operation record for the Delaware River at Montague, NJ. (table 10) indicated 0.02 percent more discharge for the year than the published U.S. Geological Survey record for the gaging station at that site (table 16), and daily records were in good agreement.

Diversion Tunnels

Records of diversions through the East Delaware, West Delaware, and Neversink Tunnels (fig. 1) were furnished to the River Master's Office by the City of New York. These records were obtained from New York City's calibrated instruments connected to venturi meters installed in the

27

tunnel conduits. The onsite venturi rates-of-flow were transmitted electronically to the New York City Department of Environmental Protection computer at the Rondout Effluent Chamber every 15 seconds. Every five minutes the computer system calculated the release and diversion quanti­ ties for the preceding five-minute periods based on the latest instantaneous rates-of-flow. These five-minute quantities were added to calculate the daily total flows which were reported to the River Master office daily. The diversion values were checked weekly against the flow meter total­ izer readings onsite and calibrated or corrected as necessary. Current-meter measurements were made by the River Master's office to verify the reported diversions. The measurements were made in the outlet channels downstream from the tunnels.

The East Delaware Tunnel is used to divert water from Pepacton Reservoir to Rondout Reservoir. Conditions in the outlet channel of the East Delaware Tunnel were unfavorable for the measurement of flows from December 31, 1992 to February 25, 1993 and March 30 to July 7, 1993, because of high water levels in Rondout Reservoir. The results of three current-meter mea­ surements made at other times during the report year showed that on the average, the venturi- meter instruments gave higher discharges by 3.1 percent for the totalizer and 2.5 percent higher for the rate-of-flow indicator.

Comparison of the data provided by New York City with discharges obtained from recorded gage-heights and the rating curve for the weir on the outlet channel from the East Dela­ ware Tunnel indicate that the data provided by New York City were within acceptable limits.

The hydroelectric plant at the downstream end of the East Delaware Tunnel operated most days of the year. When the powerplant was not in operation, a small amount of leakage through the wicket gates was not recorded on the totalizer. The results of current-meter measurements made in previous years and observations made in 1993 indicate that the leakage has not changed substantially with time and is approximately 8.0 Mgal/d. Because the powerplant was not in oper­ ation for the equivalent of 79 days during the 1993 report year, the unmeasured leakage was approximately 630 Mgal. Based upon the measurements obtained this year and in previous years, the record of diversions through the East Delaware Tunnel was substantially correct.

The West Delaware Tunnel is used to divert water from Cannonsville Reservoir into Rondout Reservoir. Two current-meter measurements of flow in the West Delaware Tunnel outlet channel were made during the report year. Those measurements and two measurements, one made just before and one just after the end of the report year indicated that on the average the venturi instruments gave higher results, 5.3 percent for both the totalizer and the rate-of-flow indicator. Inspections of the channel downstream from the outlet, when valves were closed, showed negligi­ ble leakage.

A hydroelectric plant uses water diverted through the West Delaware Tunnel. However, it operates only when diversions are less than 300 Mgal/d. When the powerplant is not operating, the valves on the pipelines to the powerplant are closed, and there is no leakage through the sys­ tem. The results of the measurements and inspections made this year and during past years indi­ cate that the reported record of the quantity of water diverted through the West Delaware Tunnel was substantially correct.

28

The Neversink Tunnel is used to divert water from Neversink Reservoir into Rondout Res­ ervoir. Two measurements of flow from the Neversink Tunnel were made during the report year. Those measurements and one measurement made before the beginning of the report year showed that on average, the venturi instruments were 1.4 percent higher for the totalizer and 1.2 percent higher for the rate-of-flow indicator.

A hydroelectric plant uses water diverted through the Neversink Tunnel. When the power- plant is not operating and the main valve on the diversion tunnel is open, leakage occurs that is not recorded on the venturi instruments. Based on measurements made during previous years, the average rate of leakage was 14.0 ft3/s (9.0 Mgal/d). When the powerplant was operating, the leak­ age was included in the recorded flow. When the main valve on the tunnel is closed there is no leakage.

During the 1993 report year, the power plant did not operate for part of the day most of the time and was not operated the equivalent of 177 days. Based on the above rate and on records of power plant operation, approximately 1.6 Bgal of water was diverted but unrecorded.

DIVERSIONS BY NEW JERSEYThe Amended Decree allows New Jersey to divert water from the Delaware River (or its

tributaries in New Jersey) to areas outside the Delaware River Basin without compensating releases. These diversions may not exceed 100 Mgal/d (154.7 ft3/s) as a monthly average, with the diversion on any day not to exceed 120 Mgal/d (185.6 ft3/s). The U.S. Geological Survey gag­ ing station, Delaware and Raritan Canal at Port Mercer, New Jersey (fig. 1) is used as the official location for measuring the diversions by New Jersey (table 17).

The following tabulation lists the allowable diversions by New Jersey, the periods that they were in effect, and the maximum monthly diversion during each period for the report year.

Effective dates Allowable diversion Maximum monthly ______________________Mgal/d______average diversion (Mgal/d)Dec. 1,1992 to Sept. 20, 1993 100 101Sept. 21 to Nov. 30, 1993__________85____________87.4________

The 30-day average diversion was computed weekly throughout the year to monitor com­ pliance with the terms of the Decree and with the reduced diversions allowed during the period of drought warning. The maximum 30-day average diversion was 101 Mgal/d during June, 1993. The maximum daily diversion was 107 Mgal on June 20, 22,24, 25 and July 1,1993. These com­ putations show that the diversions by New Jersey as measured at Port Mercer exceeded the limits allowed by the Decree during June and exceeded the reduced limits in effect during the drought- warning period in November. Whereas the data indicates that the allowable diversions were exceeded, the diversions were within the accuracy of the data and the preliminary records for the gaging station indicated that they were within the allowable limit. When the records were cor­ rected and the error was discovered, the diversions were immediately reduced to allowable levels.

CONFORMANCE OF OPERATIONS AS PROVIDED UNDERAMENDED DECREE OF THE U.S. SUPREME COURT

DATED JUNE 7,1954

Operations were conducted as prescribed by the Decree from December 1,1992 to August 7, 1993, the "Lower Basin Drought Warning and Drought Operating Plan" (DRBC Resolution 88- 22 Revised) August 8 to September 20, and the "Interstate Water Management Recommendations of the Parties to the Decree (DRBC Resolution 83-13)," which were designed to alleviate the drought-warning conditions in the basin from September 21 to November 30, 1993.

Diversions from the Delaware River Basin to the New York City water-supply system were less than those authorized by the Decree, the Interstate Water Management Recommenda­ tions of the Parties to the Decree and the agreements among the Parties to the Decree.

Under Compensating Releases of the Montague Formula, New York City released water from its reservoirs at rates designed by the River Master to maintain the applicable Montague flow objectives and complied fully with the directives of the River Master during the year.

Diversions from the Delaware River Basin by New Jersey were within the limits pre­ scribed by the Decree, et al, except as described earlier. New Jersey also complied fully with the requests of the River Master.

WATER QUALITY OF THE DELAWARE RIVER ESTUARY

By Charles R. Wood

INTRODUCTIONThis section describes the water-quality monitoring program conducted by the U.S. Geo­

logical Survey in the Delaware Estuary during the 1993 report year. Also presented here are some of the data that were obtained by this, program and a brief discussion of the significance of the data.

WATER-QUALITY MONITORING PROGRAMWater quality of the Delaware River and Estuary was monitored between Trenton, N.J.,

and Reedy Island Jetty, Del. Data were acquired continuously by electronic instruments at five monitor sites: one at Trenton just upstream of the head of tidewater and four in the estuary (fig. 6). At Fort Mifflin, the water was monitored for two parameters: temperature and specific conduc­ tance. At the remaining sites, the water was monitored for four parameters: temperature, specific conductance, dissolved oxygen, and pH.

Additional data were obtained twice a month from March to November at 18 sites between Fieldsboro, N.J., and the mouth of the Mahon River (fig. 6). At each of these sites, sam­ ples of water were collected at the center of the river channel. These samples were analyzed for 28 parameters including temperature, chloride, alkalinity, specific conductance, dissolved oxygen, andpH.

Data obtained from the continuous monitoring sites were processed by computer and stored for future reference by the U.S. Geological Survey. They were also distributed regularly to cooperators and published annually by the U.S. Geological Survey in "Water Resources Data for Pennsylvania, Volume 1, Delaware River Basin." Data from the twice-a-month sites were col­ lected by the State of Delaware for the Delaware River Basin Commission (DRBC) at 18 sites. These data are available from the DRBC and from STORET, the U.S. Environmental Protection Agency's data storage system. The above described programs were carried out in cooperation with the Delaware River Basin Commission, Delaware River Master, and other agencies of fed­ eral, state, and county governments.

ESTUARINE WATER-QUALITY DATA DURING 1993The following is a summary and discussion of the data that were collected during the 1993

report year.

71

Streamflow

Streamflow is a vital factor that influences the water quality of the estuary. Increased Streamflow usually results in better water quality by limiting salt-water intrusion and diluting the concentration of dissolved minerals, both of which contribute to a lower specific conductance and chloride level. Increased flow also aids in maintaining lower water temperature during warm weather and supporting higher dissolved-oxygen levels.

On the basis of Streamflow records for the Delaware River at Trenton, mean monthly Streamflow for the year was lowest during July (3,498 ftVs) and highest during April (49,120 fr/ s) (table 18).2 The monthly mean Streamflow was above the respective monthly mean for the period of record in December, January, April, and November, and below the monthly mean for the remainder of the year.

Temperature

The significance of water temperature in regard to water quality in the estuary lies in its profound influence on various physical, chemical, and biological properties of the water. In gen­ eral, increases in water temperature have deleterious effects on water quality by lowering the sat­ uration level of dissolved oxygen and increasing biological activities. The primary factors that control water temperature in the estuary are climatic; however, various uses of the water by man can also have significant effects.

Records from Benjamin Franklin Bridge (Pier 12 North), Philadelphia, Pa., show that mean monthly temperatures for the period March to November 1993 were below normal during March, April, October, and November, and equaled or exceeded the norm during the rest of the year. The norm is based on historical temperature records from 1962 to 1992 (fig.7).

Specific Conductance and ChlorideSpecific conductance is the ability of a solution to conduct electricity. It can be used as an

indicator of the amount of ionized material in solution and relates approximately to dissolved-sol- ids content.

Specific conductance values in bodies of water usually reflect the geochemistry of the drainage basin; however, pollution and the intrusion of oceanic salts can also have a considerable effect on specific conductance. Increasing streamflows reduce the concentration of dissolved sol­ ids; thus, lowering specific conductance and chloride levels. Conversely, decreasing flows have the opposite effects.

In the Delaware Estuary, the intrusion of oceanic salts is important to those who must use the estuary as a water supply. For this reason, chloride concentration is of great interest. Water with chloride concentrations in excess of 250 mg/L (milligrams per liter) is usually considered undesirable for domestic use, and water with concentrations in excess of 50 mg/L is unsatisfac­ tory for some industrial uses.

Figure 7.- Mean monthly temperatures of the Delaware River Basin at Benjamin Franklin Bridge, Philadelphia, Pennsylvania.

As sea water has a chloride concentration of approximately 19,000 mg/L, the location of a body of water in relation to the sea can influence chloride levels in that body of water. For this reason, chloride concentrations in the Delaware Estuary generally increase with distance down­ stream toward the Delaware Bay and Atlantic Ocean.

Chloride concentration was not measured directly at Fort Mifflin, Pa., and Reedy Island Jetty, Del, but a correlation between specific conductance and chloride concentration has been developed on the basis of analyses of water samples collected from the estuary. Chloride concen­ trations estimated from that correlation are presented in tables 19 and 20. The correlation is less reliable when chloride concentrations are lower than 30 mg/L because other ionized materials may be present in amounts large enough to affect the conductance-chloride correlation. Therefore, chloride concentrations derived from specific conductance are not given when chloride concentra­ tions of less than 30 mg/L are indicated. Chloride concentrations at Chester, Pa., (table 21) were furnished by Scott Paper Company.3

73

At Fort Mifflin, the maximum daily chloride concentration for March through October equaled or exceeded 50 mg/L, 10 percent of the time (see table 19). The maximum was 120 mg/L on August 17 and 18. At Chester, the minimum daily chloride concentration equaled or exceeded 50 mg/L, 26 percent of the time. The maximum daily concentration was greater than 50 mg/L, 46 percent of the time (see table 21). The maximum daily chloride concentration was 620 mg/L on September 4. Minimum chloride concentrations at Reedy Island Jetty were less than 30 mg/L on several days. Except for a period of very low chloride concentration coinciding with a major spring runoff event in late March and April, maximum chloride concentrations typically ranged from 2,000 to 7,000 mg/L. The maximum at this site was 7,600 mg/L on July 19 and August 15, 16, and 17.

Dissolved Oxygen

Dissolved oxygen is necessary in water for the respiration of aquatic organisms. It also plays a significant role in chemical reactions in aquatic environments. The major sources of dissolved oxygen in water are diffusion from the atmosphere and photosynthesis in aquatic plants. Dis- solved-oxygen concentrations are limited by temperature, salinity, and the partial pressure of atmospheric oxygen.

Dissolved-oxygen levels in the estuary tend to be highest near Trenton and tend to decrease with distance downstream to a point near or somewhat downstream from the Benjamin Franklin Bridge, where minimum values are usually reached. During the past year, daily mean dissolved- oxygen concentration at the Benjamin Franklin Bridge was below 5 mg/L from June 21 through September 29 (table 22). The minimum daily mean was 2.9 mg/L on July 17 and 18. At Chester, the daily mean dissolved-oxygen concentration was below 5 mg/L on June 26 through July 29 and September 4, 7, 9, 11, and 12 (table 23). The lowest daily mean was 3.2 mg/L on August 12, 13, and 14. The minimum hourly value was 3.5 mg/L on August 20. At Reedy Island Jetty, the mini­ mum hourly value was 4.4 on July 9.

The frequency of hourly dissolved-oxygen concentration at Benjamin Franklin Bridge and at Chester during the critical summer period, July through September 1993 is shown in figure 8. At Chester, dissolved-oxygen concentration was equal to or below 4 mg/L, 36 percent of the time in 1993, as compared to 6 percent of the time in 1992 and never dropping that low in 1991. At Benjamin Franklin Bridge, the dissolved-oxygen concentration was equal to or below 4 mg/L, 65 percent of time in 1993, as compared with 32 percent of the time in 1992 and 51 percent of the time in 1991.

Hydrogen-Ion Activity (pH)

Hydrogen-ion activity (pH) is fundamentally a measure of acidity or alkalinity. Values of pH below 7 indicate acidic water, whereas values above 7 indicate alkaline water. In natural waters, pH generally ranges from 6.0 to 8.5. The main factors controlling the pH of a body of water are usually the geochemistry of the drainage basin and external influences such as pollution. Photo- synthetic activity can also have a considerable influence on pH values. Increased photosynthetic activity (algal bloom) produces higher pH values. All pH values at Benjamin Franklin Bridge, Chester, and Reedy Island Jetty were in a range of 6.2 to 8.1. The pH range for each station is: Reedy Island Jetty, 6.6 to 8.2; Chester, 6.6 to 7.6; Benjamin Franklin Bridge, 6.4 to 7.4. The pH in the estuary tends to be lowest near Trenton, N.J., and tends to increase downstream.

DOCKET NO. D-77-20 CP (REVISION NO. 2)

DELAWARE RIVER BASIN COMMISSION

Modifications To The Schedule Of Release Rates FromPepacton and Neversink Reservoirs

Delaware and Suliivan Counties. New York

PROCEEDINGS

This is an application submitted by the New York State Department of Environmental Conservation (NYS DEC) for approval of a revised schedule of augmented conservation release rates from Pepacton and Neversink Reservoirs to be tried on an experimental basis for up to three years (June 1993 - May 1996).

The current schedule of augmented conservation release rates from Cannonsville, Pepacton and Neversink Reservoirs was added to the Comprehensive Plan and approved by the Delaware River Basin Commission (DRBC) pursuant to Section 3.8 of the Compact on November 30, 1983 by Docket No. D-77-20 CP (Revision). The current release rates were established on an experimental basis first, and later made permanent by the DRBC and parties to the 1983 Good Faith Agreement "Proceedings" leading to such actions are described in Docket No. D-77-20 CP (Revised). This application (including the Proposed Augmented Conservation Release rates) was reviewed for inclusion of the project in the Comprehensive Plan and approval under Section 3.8 of the Delaware River Basin Compact. A public hearing on this project was held by the DRBC on June 23, 1993.

RESERVOIR RELEASE PROGRAMS

A. Proposed Conservation Releases.

In order to further protect and enhance the recreational use of waters affected by releases from the Pepacton and Neversink Reservoirs, and based on the experience gained since the augmented reservoir release regulations were implemented, the following revisions to the current release rates are proposed for an experimental period of three years (June 1993 - May 1996):

D-77-20 CP (Revision No. 2) (Reservoir Release Rates Modif.)

B. Basic Montague Release.

At all times, New York City would be required to make such releases as directed by the River Master designed to maintain a minimum basic flow of 1,750 cfs at the Montague gaging station, or the excess release rate during the seasonal period, as already required by the 1954 U.S. Supreme Court Decree.

C. Special Thermal Stress Releases.

Special releases may be made from one or more of the reservoirs in order to relieve thermal stress conditions which pose a threat to fisheries. The total volume of such releases shall not exceed 6,000 cfs-days from all reservoirs. As set forth in Docket No. D-77-20 CP (REVISION), thermal releases, with a one-day lead time, would be made whenever the maximum water temperature in designated downstream areas as determined from measurements at Callicoon, Bridgeville, Woodbourne, or Hale Eddy is projected to exceed a maximum of 75° F, or a 72° F daily average. If the 6,000 cfs-days reserve is not used by October 31 of any year, it will not be used thereafter. No releases for relieving thermal stress would be required from November 1 to April 30 of any year. Releases for purposes of relieving thermal stress shall be at the direction of NYS DEC.

D. Drought Warning and Drought Conditions.

The augmented conservation release will be reduced to the basic conservation release (shown in Table 1, Column 1) during drought warning and drought periods as defined by the attached reservoir storage curves entitled "Operation Curves for Cannonsville, Pepacton, and Neversink Reservoirs" (Figure 1) except that when the Delaware River Master directs releases according to the provisions in the basinwide drought plan as adopted in DRBC Resolution 83-13, New York City shall make such releases from Cannonsville, Pepacton, and Neversink Reservoirs as are necessary and sufficient to maintain the constant minimum flows (specified in Table 1, Column 3) on the West Branch Delaware River, East Branch Delaware River, and the Neversink River, and provided that the total amount of water released from the three reservoirs does not exceed the amount directed by the Delaware River Master., If the amount of directed releases by the River Master is not sufficient to maintain the augmented releases from all reservoirs, the releases from each reservoir will be determined at the discretion of NYS DEC and New York City- Department of Environment Protection (NYC DEP).

Following a drought, a return to the proposed augmented conservation release rates shown in Column 3 of Table 1 shall not be made unless and until combined storage in the three reservoirs reaches 25 billion gallons above the drought warning level, as shown in Figure 1, and remains at or above that level for 15 consecutive days.

87

D-77-20 CP (Revision No. 2) (Reservoir Release Rates Mod if.)

E. Plans Concerning Cannonsville Release Rates.

Installation of a new release valve for the Cannonsville reservoir is scheduled to be completed before the end of 1994 and should provide the needed flexibility in making releases to enhance fisheries management

During the first year of the experimental period, conservation releases from Cannonsville reservoir, which are considered inadequate by NYS DEC, would continue to be made at the current release rates. However, as part of this experimental program, releases from the thermal stress bank will be varied for short periods to study the impact of such releases in mitigating thermal stress conditions at Hale Eddy, Hancock, Lordville, Hankins, Long Eddy and Callicoon. Such operations are designed to conserve the available thermal stress bank and enable NYS DEC to improve fisheries management in the Delaware River.

Ryan thermal gages would be installed at 20 strategic locations below the reservoirs to supplement the existing USGS gaging stations. Data collected would be used to fine tune the water temperature models being developed by NYS DEC in cooperation with NYC DEP and USGS. Experience gained from the above experimental program should lead to improved management of the thermal stress bank.

During the first year of the experimental period, alternative release schemes would be evaluated jointly by NYS DEC and NYC DEP using the existing monthly reservoir simulation model (MRSM) to maximize the use of the new valve. The resulting scheme would be the basis for implementation of an experimental program at Cannonsville.

During the proposed experimental period, increases in augmented conservation release rates during the summer months will be offset with decreases during other months with no changes in the total releases on a yearly basis.

DRBC staff has operated the dairy flow model for the critical drought years, 1961 through 1964, using the modified augmented release schedule as proposed (Table 1, Column 3) and determined that the period of drought warning would be increased by one day in 1961 and one day in 1962, with no changes in 1963 and 1964. Accordingly, application of the Proposed Augmented Conservation Release rates specified in the experimental program should not have a significant impact on drought management in the Basin.

D-77-20 CP (Revision No. 2) (Reservoir Release Rates Modif.)

As documented in Docket No. D-77-20 CP (REVISION), the NYS DEC evaluations, to date concerning the monitoring program, indicate that the augmented conservation release program has improved and extended fisheries downstream from the three New York City reservoirs, and other water-related recreational activities have shown increases since the initiation of the experimental program in 1977.

The project does not conflict with or adversely affect the Comprehensive Plan. It provides beneficial use of the water resources and does not adversely influence the present or future use and development of the water resources of the Basin.

DECISION

I. The project, as described above, with modifications specified hereinafter, is hereby added to the Comprehensive Plan.

II. The project is approved pursuant to Section 3.8 of the Compact, subject to the following conditions:

a. Monthly summaries of reservoir operations submitted by NYC DEP to NYS DEC shall also be submitted to the DRBC.

b. Detailed operational records of each reservoir, maintained by both the City and State Reservoir Release Managers, shall be available to the DRBC upon request.

c. The provisions of the reservoir release program approved herein shall not be applicable to any action taken by NYC DEP or NYS DEC with regard to the operation of the Cannonsville, Pepacton, or Neversink Reservoirs in any emergency situation where there is a threat to the continued existence or safe operation of the dams or tunnels or to any appurtenant structures or to the public health or safety. Any emergency action shall continue only for such time as is necessary to avert the threat and is subject to the approval of the Executive Director of the DRBC.

d. Increases in the augmented conservation release levels may not be made except in accordance with the allowances provided for in the Stipulation of Discontinuance in The City of New York vs. The State of New York Department of fiflvfrngipental Conservation, Index No. 5840-80, and shall be subject to approval by the DRBC.

e. Releases under emergency conditions. The Commission retains its power under Section 3.3(a) and Article 10 of the Compact to declare a drought emergency after consultation with the River Master, in order to conserve the waters in the Delaware River and its tributaries and in the reservoirs of the Upper Delaware River Basin, in order to protect water supply, health, and safety of the residents of the Delaware River Basin and its service area. The River Master retains all of his powers under the Decree including the powers under Article VII, B.I of the 1954 Decree to conserve the waters in the river, its tributaries, and in reservoirs owned by the City of New York, or in reservoirs developed by other parties to the Decree after 1954.

f. A progress report describing the results of the experimental program shall be submitted by August 1 of each year, beginning August, 1994.

AGREEMENT

The parties to the U. S. Supreme Court decree convened at 1:00 P.M. on September 22, 1993, at the Goodstay Center, Wilmington, Delaware pursuant to the Delaware River Basin Commission Resolution No. 83-13, to consider modification of current diversions to New York City and New Jersey, releases from the New York City reservoirs, and target flows at the Montague and Trenton gauging stations.

The modifications agreed to were:

1. Establishment of an emergency fisheries protection program designed to allow special stream releases by the NYSDEC within the term specified with this Agreement as requested as specified in Section (d). The emergency program includes the following provisions:

a. There will be no net loss of the reservoirs' storage capacity.

b. The maximum use of 3,000 cfs-days will be paid back by DEC to the City through reductions in releases required for Montague.

c. The credits from releases required for Montague targets may occur at the following rates when the Trenton flow objective is at or above 2,700 cfs.

When Montague design target Allowed credit reduction in equals or exceeds directed releases

1600 cfs 100 cfc

1500 cfs 50 cfc

d. The term of this program begins September 22, 1993 and usage continues until extended or upon entry into drought emergency as determined by Resolution No. 83-13, when it will be automatically terminated. Reductions to Montague directed releases will continue until total storage is paid back or until reservoirs spill.

e. The releases under this program shall not exceed the augmented releases as established in Resolution No. 77-20 (Revision 2), except, for one interim step not to exceed 24 hours when directed releases have ceased and streamflows are being reduced below augmented conservation levels or to limit temperatures to 75° F, maximum, at Hancock, East Branch and Bridgeville.

92

f. The operation of this emergency program will be directed by NYSDEC upon a continuing showing to the Parties of this Agreement of need for these extra releases; and will be coordinated with the River Master and New York City. DRBC will be informed of the River Master's directed releases each day when it is computed and NYSDEC will report each request for an augmented release.

g. In accordance with the 1980 stipulation of discontinuance between New York City and NYSDEC, NYSDEC agrees to reimburse New York City for all lost hydroelectric power revenues, if any, caused by this emergency reservoir releases program.

h. The parties to this agreement will reconvene by meeting or telephone call to reconsider these arrangements when a significant change in conditions so dictates.

i. These modifications will take effect immediately and will continue until modified by unanimous agreement of the Parties or terminated by any one of these Parties.
