Concentration of Dissolved Gases in the Willamette Cowlitz and Boise Rivers 1970-72

BRUCE H MONK1 EARL DAWLEY1 and KIRK BEININGEN2

ABSTRACT Data on dissolved nitrogen dissolved oxygen total gas pressure and water

temperatures are presented for the Wlllamette Cowlitz and Boise rivers Water samples were taken upstream and downstream of dams and over a wide range of river and dam discharges to obtain data on the relation between river flow and dam discharges and their effect on the total gas regime of the rivers

INTRODUCTION

In recent years fishery scientists have shown that high concentrations of dissolved atmospheric gases in the Columbia and lower Snake rivers cause gas bubble disease and during years of high flow can result in up to 68 mortality of juvenile and adult Pacific salmon Oncorhynchus spp and steelhead trout Samo gairdneri (Ebel 1971 1973) The high concentrations occur when air is entrained in water passing over spillways and forced into solution by high pressures in the stilling basin (Ebel 1969 Beiningen and Ebel 1970)

In 1970 fishery agencies and the US Army Corps of Engineers became concerned that heavy spilling of water over Lost Creek Dam (now under construction 247 km from the mouth of th~ Rogue River) would create supersaturated concentrashytions of dissolved gas harmful to native stocks of salmon and steelhead trout and to hatcheryshyreleased stocks of coho salmon O kisutch and fall chinook salmon O tshawytscha Hatchery stocks could also be affected by supersaturated water supplied to the hatchery by a regulating reservoir downstream from the dam Therefore a nitrogen monitoring program was established at various hydroelectric projects which would be pertinent to spillway design modifications at Lost Creek Dam The program included many projects on the Willamette Valley system Lucky Peak Dam on the Boise River and Mayfield Dam on the Cowlitz River (Figs 1 2 3) There was also concern over the possibility of high concenshytrations in the reservoirs below Green Peter Dam and Lookout Point Dam (Fig 2) which supply

water for South Santlam Hatchery and Dexter Rearing Ponds respectively (operated by Fish Commission of Oregon)

To determine whether discharges from the dams on the Willamette and Cowlitz River systems would create supersaturated concenshytrations of dissolved gas extensive sampling and analysis for dissolved gases was done during 1970 1971 and 1972 Samples were taken near dams over a wide range of river flow and spillway and regulating outlet discharges (regulating outlets are low level valved gates used to draw down reservoir water levels farther than pOSsible by spilling) to obtain data on the relation between river flow and dam discharges and their effect on the total gas regime of the rivers

Atlditlonal samples were taken at Lucky Peak Dam on the Boise River (Fig 3) to determine the concentrations of dissolved gases below a flip bucket designed to diSSipate energy In the spillrace and thereby eliminate supersaturated concentrations The US Army Corps of Engishyneers felt that such deflectors if effective could be a possible answer to the potential supershysaturation problem at Lost Creek Dam

This report presents data on gas concentrations and related water temperatures of water samples taken at forebays and tailraces of dams In the Willamette River drainage Mayfield Dam on the Cowlitz River and Lucky Peak Dam on the Boise River All sampling and analysiS were done by the National Marine Fisheries Service under contract with the US Army Corps of Engineers

PROCEDURE Water samples were collected with a modified

Van Dorn sampler and then put In standard bioshychemical-oxygen-demand sample bottles (300

1

ml) by means of a tube running from the bottom of the sampler The air interface and agitation of sample were minimized by placing the tube at the bottom of the sample bottle The bottles were allowed to overflow up to 3 times their volume and were immediately placed in a chilled Ice chest

All of the samples were analyzed within 24 h of the time of collection Dissolved nitrogen analshyyses were done with an Arthur H Thomas modishyfication of the Van Slyke-Nelll manometric blood gas analyzer (Van Slyke and Neill 1924) and with a Fisher-Hamilton gas partitloner model No 29 The method used was that described by Swlnnershyton Linnenbom and Cheek (1962)

The gas partitioner was calibrated by analyzing at least three samples on the partltioner and the Van Slyke A graph of partltloner units versus Van Slyke concentration values (milligrams per liter) was established so that other samples could be run on the partitioner and resulting saturation values derived from the graph An Alsterburg modified Winkler method was used for the determination of the dissolved oxygen levels and similar calibration techniques were used to calibrate the partitioner (American Public Health Association 1971)

PRESENTATION OF DATA Tables 1-12 correspond to the numbers in

Figures 2 and 3 which indicate the dams where water was sampled These tables give the locations of the various sample stations at each dam and the dates on which samples were taken They also give dissolved oxygen concentrations (mgll and of saturation) dissolved nitrogen plus argon concentrations (mill N2 + Ar and of saturation) total gas pressure (mm Hg and of saturation) and related water temperature (0C) Saturation values were calculated from tables by

Weiss (1970) and then corrected for altitude In cases where hourly spill flow and hourly total flow are equal the samples were taken directly from spillway discharge and there was no possibility of dilution by turbine discharge When the total hourly flow Is larger than the hourly spill the sample was taken during both spilling and powerhouse operation and there was a good

possibility of the discharges mixing

ml) by means of a tube running from the bottom of the sampler The air interface and agitation of sample were minimized by placing the tube at the bottom of the sample bottle The bottles were allowed to overflow up to 3 times their volume and were immediately placed in a chilled Ice chest

All of the samples were analyzed within 24 h of the time of collection Dissolved nitrogen analshyyses were done with an Arthur H Thomas modishyfication of the Van Slyke-Nelll manometric blood gas analyzer (Van Slyke and Neill 1924) and with a Fisher-Hamilton gas partitloner model No 29 The method used was that described by Swlnnershyton Linnenbom and Cheek (1962)

The gas partitioner was calibrated by analyzing at least three samples on the partltioner and the Van Slyke A graph of partltloner units versus Van Slyke concentration values (milligrams per liter) was established so that other samples could be run on the partitioner and resulting saturation values derived from the graph An Alsterburg modified Winkler method was used for the determination of the dissolved oxygen levels and similar calibration techniques were used to calibrate the partitioner (American Public Health Association 1971)

PRESENTATION OF DATA Tables 1-12 correspond to the numbers in

Figures 2 and 3 which indicate the dams where water was sampled These tables give the locations of the various sample stations at each dam and the dates on which samples were taken They also give dissolved oxygen concentrations (mgll and of saturation) dissolved nitrogen plus argon concentrations (mill N2 + Ar and of saturation) total gas pressure (mm Hg and of saturation) and related water temperature (0C) Saturation values were calculated from tables by

Weiss (1970) and then corrected for altitude In cases where hourly spill flow and hourly total flow are equal the samples were taken directly from spillway discharge and there was no possibility of dilution by turbine discharge When the total hourly flow Is larger than the hourly spill the sample was taken during both spilling and powerhouse operation and there was a good

possibility of the discharges mixing
