The smelt outmigration was monitored at wapatox on the Naches
River and Prosser on the lower Yakima. The spring outmigration at
Wapatox was estimated to be 16,141 smolts. The 1987 spring
outmigration of wild spring chinook from the Yakima Basin was
estimated to be 251,975 smolts at Prosser.
The survival from egg to smelt was calculated using the 1985
redd counts and the 1987 smolt outmigration at Prosser. The
estimated survival was 4.16%, which gives a mean egg to srnolt
survival over four years of 6.32%.
In 1987 a total of 3,683 adult and 335 jack spring chinook
salmon returning to the Yakima River were counted at Prosser fish
ladder. This gives a total of 4,018 salmon returning to Prosser
Dam. The median dates of passage were May 12 and May 16 for
adults and jacks respectively. AIJ additional 372 fish were
estimated to have been caught in the Yakima River subsistence
dipnet fishery below Horn Rapids and Prosser Dams. Therefore,
total return to the Yakima system was 4,390 spring chinook salmon.
Spring chinook were counted at Roza Dam from May 1 to
September 30, 1987. Passage at Roza Dam was 1,610 adult and 67
jack spring chinook for a total of 1,677 wild fish. The median
dates of passage at Roza Dam were May 29 and May 26 for spring
chinook adults and jacks respectively.
The smolt to adult (Ssa) survival was calculated based on
the 1983 smelt outmigration estimated at Prosser and the 1984
ix
return of jacks (3 year old fish) the 1985 return of four year old
adults, and the 1986 return of five year old fish to the Yakima
River. It was estimated that 6,012 wild three, four, and five
year old fish returned from an estimated smolt outmigration of
135,548 fish in 1983. This gives an estimated survival from snolt
to adult of 4.4%.
The smolt to adult survival for the 1984 smolt
outmigration was 5.3% with 423 jacks returning in 1985, 5,163 four
year old adults returning in 1986, and 983 five year old fish
returning in 1987 fran an estimated 123,732 smolts in 1984.
Spring chinook adults from fourteen different hatchery
release groups were recovered in 1987. A total of 211 coded wire
tags were recovered and these were expanded to an estimated 253
returning hatchery fish in 1987. Nine of these fish were jacks.

3.0 INTRODUCTION
The population of Yakima River spring chinook salmon
(Qncorhvnchus tshawvtscha) has been drastically reduced from
historic levels reported to be as high as 250,000 (Snoker, 1956).
This reduction is the result of a series of problems including
mainstem Columbia dams; dams within the Yakima itself; severely
reduced flcws due to irrigation diversions; outmigrant loss in
irrigation canals; increased thermal and sediment loading; and
overfishing. Despite these problems, the escapement of spring
chinook to the Yakima River has continued at levels ranging from
166 to 9,442 since 1957.
In October, 1982, the Bonneville Power Administration
contracted the Yakirra Indian Nation to develop methods to increase
production of spring chinook in the Yakima System. The Yakima
Nation's current enhancement policy attempts to maintain the
genetic integrity of the spring chinook stock native to the Yakti
Basin. Relatively small numbers of hatchery fish have been
released into the basin in past years. Data from the Wenatchee
System indicate a return rate from hatchery smolts of less than
.25% (Mullan, 1982). Return rates from the current Yakima study
smolt releases are .07%. These low return rates indicate that few
fish would have returned from these early hatchery releases. Thus
the genetic input from hatchery fish into Yakima Basin stocks is
probably negligible.
The goal of this study is to develop data that will be used
to present management alternatives for Yakima River spring
chinook. The study has five major objectives. The first
objective is to determine the distribution, abundance and survival
of wild Yakima River spring chinook. Naturally produced
populations are being studied to determine if these runs can be
sustained in the face of present harvest and environmental
conditions. Survival through each life stage is being evaluated in
an attempt to determine limitations to natural production in the
basin. Survival to emergence studies are being conducted to
determine survival through the incubation stage. Analysis of the
relationship between survival to&emergence and gravel substrate
quality is being undertaken. Seining at selected sites and
electroshocking surveys have been conducted to evaluate
distribution and abundance of juvenile fish. Snolt outmigrations
are monitored at the Wapatox juvenile trap on the Mches River and
at the Prosser juvenile trap on the mainstem Yakima River. Adult
returns are determined by monitoring the Yakima Tribal dipnet
fishery, counting adults at Presser and Roza fish ladders, and
through spawning ground surveys. Physical parameters such as
water temperatures and stream flow are monitored throughout the
basin.
The second major objective of this study is to determine the
relative effectiveness of different methods of hatchery
supplementation. This objective is divided into three
sub-objectives:
a) Determination of optimal release time Snolt releases are
the norm, but fingerlings were released in June, September, and
November of 1984 and 1985. Downstream survival of these smolts
was evaluated and adult returns are being monitored.
b) Determination of optimal manner of release In the past,
fish have either been transported from a hatchery and released
into the Yakirna River, or raised in rearing ponds. These methods,
as well as the use of acclimation ponds, will be evaluated.
c) Determination of optimal release stocks Smelts were
released in 1986 and 1987 as hatchery x hatchery, hatchery X wild,
and wild X wild crosses to determine the effect of genetic makeup
on the success of various releases. Success will be measured as
the number of adults returning, as well as whether spawning timing
is similar to the wild stock.
Adverse interactions between hatchery releases and wild stocks
were minimized by scatter-planting hatchery fish so densities in
the river remained low enough to minimize competition for food and
space.
The last three major objectives of the study are:
3) to locate and define areas in the watershed which may be used
for the rearing of spring chinook;
4) to define strategies for enhancing natural production of
spring chinook in the Yakima River; and
5) to determine the physical and biological limitations on
production within the system.
These objectives will be met at the end of the study when the
database is complete.
This project is a multi-year undertaking that will evaluate
different management and enhancement strategies. At the
conclusion of this study, a series of alternatives will be
3
developed that can be used to determine how best to enhance the
runs of spring chinook in the Yakima Basin. Annual reports were
presented for 1983 (Wasserman and Hubble, 1983), 1984 (Wasserman,
Hubble, and Watson, 1985), 1985 (Fast, Hubble, and Watson, 1986)
and 1986 (Fast, Hubble, and Watson, 1986). A detailed description
of methods and materials used in this study can be found in these
earlier reports. This current report is concerned with new
findings in 1987 and some re-evaluation of previous data in light
of current information.
4.0 DESCRIPTION OF SIUDY AREA
The Yakima River is located in central Washington and flows
217 miles from its headwaters in the Cascade Mountains (elevation
2,448 ft) to the Columbia River near Richland at river mile (RM)
335 (Figure 1). The Yakima River Basin drains 6,155 square miles
of the east slopes of the Cascade Mountains in Kittitas and Yakima
Counties. The Yakima River flows east and south through the
Kittitas Valley from its ruggedly glaciated headwaters. south of
the valley the river cuts through Manastash and Urntanum ridges in
a deep canyon. The river enters the middle valley above Yakima
through a gap cut in Selah Ridge and leaves through Union Gap in
Ahtanum Ridge. Rattlesnake Hills, crossing eastern Yakima and
northern Benton Counties, and the Horse Heaven Hills to the south
are prominent features bordering the lower river in its 80 mile
reach from Union Gap to the Columbia River. The Yakirna River
enters the Columbia River near Richland at an elevation of 300
feet.
The major tributaries, with the exception of Satus and
Toppenish Creeks, enter the river above the city of Yakima. The
Naches River is the largest tributary, entering the Yakima at RM
101 and extending 51 miles to the junction of the Bumping and
Little Naches Rivers. The Naches River drains an area of 1,106
square miles. Other important tributaries of the Naches include
the American and Tieton Rivers and Rattlesnake Creek.

Scale In !iiles
Figure 1. TheYakimRiverE!asin inscuth-centralWashington.
Important tributaries in the upper Yakima are the Teanaway
and Cle Elum Rivers. Numerous creeks, including Manastash,
Taneum, and Swauk, flow into the Yakima in the Kittitas Valley.
The climate of the Yakima Basin varies from wet-alpine in the
Cascade Mountains to semi-arid conditions at the lower elevations.
The crest of the mountains receive 80 to 140 inches of
precipitation par year while approximately one third of the basin
receives ten inches or less. Summar temperatures average 55 F in
the mountains and 82 F in the valleys. During the winter monthly
maximum temperatures range from 25 F to 40 F and low temperatures
range from -20 F to -25 F.
The Yakti River Basin produoes 3.5 million acre feet average
annual runoff, unregulated. The U.S. Bureau of Reclamation's
Yakima Irrigation Project has transformed the semi-arid region
into a productive agricultural region. Approximately 500,000
acres are presently under irrigation, consuming 2.25 million acre
feet each year. There are numerous dams and irrigation diversions
on the river. These include Horn Rapids, Prosser, Sunnyside,
Wapato, Roza, and Easton. A screening structure is associated
with each of these dams except at Easton. For an extensive
description of the Yakima Basin, see Bryant and Parkhurst (1950).
In the Yakima system, reservoir storage acts to regulate
flows. Man-made Kachess, Keechelus, and Cle Elum Lakes in the
upper Yakima and Bumping and Rimrock Lakes on the Naches system
are the major storage sites. These storage areas supplement flows
during the irrigation season (March-October) and store water in
the winter. Irrigation and power diversions generally reduce
flows in the lower sections of the Yakima River. Sunnyside and
wapato dams near rivermile 108 divert approximately one-half the
total river flow at each site into irrigation diversions in the
summer and fall. Presser diversion removes approximately 1,400
cfs for irrigation and power production throughout most of the
year. Due to the large irrigation diversions at Presser and
Parker, flows drop dramatically in the lower river from June to
October. Approximately 50% of the flows withdrawn at diversion
sites re-enter the river downstream after being used for
irrigation or hydropower.
Prior to 1980, flaws remained high on the spawning grounds in
September and October for irrigation purposes. Many fish that
spawned at this time deposited their eggs in shallclw water near
the bank. When flows were decreased at the end of the irrigation
season, these redds were often dewatered. Following court action
in 1981 the irrigation flows were decreased in the Yakima branch
during the first week of September so that this problem would not
continue. To offset the reduction of flows from the upper Yakima
in September, flow is increased in the Naches River mainly from
Rimrock Reservoir releases. This increased flow enters the Naches
River below the areas where most spring chinook spawning occurs so
it is not believed to impact spawning success.

5.0 MEmoDs AND MATERIALS
5.1 NA!JXJFAL PRODUCTION
5.1.1 SURVIVALJ 'IO EMEFX2ENCE SIUDIES
5.1.1.1 Fry Trapping
In the fall of 1986 a total of seven spring chinook redds
were selected to be capped for survival from egg to fry studies.
The females associated with each redd were collected and the
length fecundity model developed in 1986 was used to estimate the
number of eggs deposited in each redd. The redds were capped in
February of 1987 and early emerging fry were collected and
counted. However, due to extremely high runoff during the spring
snowmelt the traps were not checked for a period of approximately
six weeks. When the flood waters receded the emergence nets were
clogged with sand and gravel and the live boxes of several traps
had been lost due to high flus. Due to the incomplete record of
fry emergence in 1987 no analysis or reporting of survival to
emergence data will be included in this annual report.

5.1.2 WINIER DISTRlBDTION STUDIES
Electroshocking for juvenile spring chinook was a>nducted
October 23 through January 8, from RM 181 downstream to RM 20 on
the Yakima River. The purpose was to determine; (1) winter
habitat selection by jwenile spring chinook, and (2) distribution
of branded wild spring chinook that had been released atwapatox
smelt trap (RM 17) on the Naches River during the fall.
A Smith-Root SR-14 electroshocker was used for collection.
Sampling sites ranged from l/2 mile in length to several miles.
General sampling proceedures consisted of mwing downstream with
the current in a zig-zag pattern between the stream bank and the
thalwag.
Fish collected were anesthetized with -222. Fork lengths
were recorded from all fish. Fish were checked for brands and
then were returned to the river after recovery. A general
description of the habitat type in which fish were found was
recorded for each sampling location.
10
5.1.3 PROSSER SMOLT TRAP
Presser smolt trap was operated continuously from March 9 to
July 31, 1987. Presser trap operates from a bypass pipe that
shunts fish from rotary drum screens in Chandler Canal back to the
mainstem Yakima River. In 1984, 1985, 1986 and 1987 trapping
efficiency (the percentage of outmigrants passing Prosser Dam
diverted into the trap) was calculated via a series of releases of
marked fish. The statistical methodology for efficiency
calculations w&s evaluated by Douglas Chapman of the University of
Washington Center for Quantitative Science. A detailed
description of the evaluation process can be found in Appendix B
of the 1986 BPA annual report. The basic procedure was as
follows. Once each week, fish captured in the trap during the
night were cold-branded. TWO groups were branded differently, with
one group released two miles upstream of the canal intake, and the
other in the canal. Efficiency (Ei) was based on the recapture
rate of branded fish as follows:
Ei = CriRri (cCi/Rci)
where Ei = fraction of fish diverted into the canal in the ithexperiment;
Rci = number released directly into the canal in theith experiment;
Rri = number released directly into the riverin theithexperiment;
%i = number recaptured from the canal releasein the ithexperiment;
and Cri = number recaptured from the river release in theithexperiment.
During the 1984, 1985, 1986 and 1987 spring chinook smelt
migrations a total of 68 separate efficiency tests were performed.
11
A relationship was developed between the combined 1984-87
efficiency data and river discharge. This relationship was then
used to estimate the total number of jwenile fish passing Prosser
dam in each of the years the trap was operating. The confidence
intervals for the calculated total smelt passage for each year was
estimated from a linearized form of the logistic equation Y =
l/l+~(-A+BX). Lengths, weights and scales were taken from random
samples of all species and release groups on a daily basis. In
addition unbranded ad-clipped hatchery spring chinook were
sacrificed for coded wire tag analysis on a daily basis.
12
5.1.4 WAPAOX SMOLT TRAP
The purpose of Wapatox smolt trap is to monitor the spring
chinook smolt outmigration in the spring and the pre-smolt
outmigration the rest of the year from the Naches subbasin.
Wapatox smolt trap is located on the Naches River at RM 17, just
downstream from the confluence of the Tieton and Naches Rivers
(see Figure 1). The trap is constructed on the Wapatox by-pass
canal. Fish entering the canal are shunted into a by-pass pipe
(culvert) by a series of rotating drum screens across the
diversion canal.
The 1986 fall trapping of spring chinook pre-smelts ceased
December 1, 1986 when the screens were removed from Wapatox
Diversion Canal. Wapatox smolt trap began operation on April 1,
1987 when the rotary drum screens were put into place. The trap
was normally checked at least 5 times per week and more often
during peak migration periods. Only salmonid species were
enumerated. Fish were anesthetized with MS-222 and fork lengths
and weights were recorded.
Test releases were made to determine trap efficiency as an
empirical function of the percent discharge diverted into the
canal (P.D.C.). Three successful tests were conducted using both
spring chinook and hatchery coho. The P.D.C. ranged from 16.7% to
28.6% over the coarse of the three tests. Canal test fish were
released at the head of the canal which is approximately 400
meters from the screens. River test fish were released
approximately 1+/2 mile upstream to the dam. Refer to the 1986 BPA
13
annual report (Appendix B) for an indepth discussion on
calculation of the trap efficiency.
The P.D.C. efficiency data from the three tests were fitted
to a linear equation. The resulting trap efficiency equation was
used to estimate daily smolt outmigration. Fall and summer
outmigration estimates were calculated, as in previous years,
assuming that trap efficinecy was directly correlated to P.D.C.
This methodolgy was used for estimation of the summer and fall
outmigation because the P.D.C. Is were generally outside of the
tested range.
When the trap was inoperable, an estimate of the daily catch
was made by interpolation of daily catches preceding and following
these periods.
14
5.1.5 ADULT REXURNS
Adult spring chinook salmon harvested below Presser in the
1987 Yakima Tribal ceremonial dipnet fishery were monitored under
the BIA 638 contract.
The Prosser and Roza Dam adult fish oounting stations were
monitored in 1987. Counting at Prosser began April 1 and
continued through September. Roza Dam was monitored from May 1
through September 30. Water clarity at Roza Dam was such that
fish swimming over the counting board could be visually examined
for the presence or absence of an adipose fin. All
adipose-clipped fish were collected in a second trap and
sacrificed to recover the coded wire tags.
Spawning ground surveys were inititated on the American River
in mid-July under a contract from the U.S. Canada Treaty. The
Yakima Indian Nation was the lead agency under a contract from the
Columbia River Inter-Tribal Fish Commission. Spawning ground
surveys were conducted throughout each reach of spawning area once
each week. All carcasses were examined for adipose fins, and fork
length and mid-eye to hypural plate length were recorded. Scale
samples were taken, and gonads were examined to determine sex and
egg retention in females. mllawing examination the tail of each
fish was removed so it would not be examined more than once.

5.1.6 ESIXMATES OF SUF'WVAL 'IRROUGHVAEUCXlSLIFE STAGES
5.1.6.1 Egg to fry:
As previously discussed, survival from egg deposition to
emergence was not canpleted in 1987. Total egg deposition was
calculated as mean fecundity of Yakima River f&es (based on the
length fecundity model) multiplied by the number of redds located
on the spawning grounds.
The total number of fry produced (F) was calculated as:
F = mean fecundity of Yakima River spawners x number of redds
X survival from egg deposition to esnergence.
5.1.6.2 Egg to Snolt:
Survival from egg to smelt (Gs) was calculated as:
ses =estimated number of smolts at Prosser
total. egg deposition for year class.
5.1.6.3 Fry to Snolt:
Survival from fry to snolt (Sfs) was estimated as:
Sfs = number of smolts estimated to Dass Presserfry for year class
16
Estimates of egg deposition and fry production were made for
1981 to 1987 based on redd counts from spawning ground surveys.
Survival from egg to smolt and from fry to smelt were based on
1981, 82, 83, 84, and 85 redd counts and 1983, 84, 85, 86, and 87
smelt outmigration estimates at Presser.
5.1.6.4 Snolt to Adult:
The complete smolt to adult survival (Ssa) of wild spring
chinook salmon in the Yakima systemwas calculated from the 1983
and 1984 smelt outmigration estimated at Presser and the return of
jacks (3 years old fish), four year old adults, and five year old
adults corresponding to each years smelt run. The jack and four
year old adults (two ocean fish) returning in 1986 and 1987
respectively, from the 1985 smelt outmigration were also analysed
for this report.

PART2
5.2 - OPERATIONS
5.2.1 CUTPLANTING STUDIES
5.2.1.1 Snolt Releases
The effectiveness of hatchery-reared "native" (wild x wild)
and "hybrid" (wild x hatchery) vs. "hatchery" (hatchery x
hatchery) smolts was assessed by transporting three such groups to
Mary's pond (RM 192 on the Yakima River) and allowing them
immediate volitional release. Fish were transported from
Leavenworth National Fish Hatchery and stocked into the pond over
the period March 19 through March 23, 1987. Release began April
14, 1987. Similar releases were made from Mary's pond in 1986.
A second group of hatchery x hatchery smelts was transported from
Leavenworth National Fish Hatchery and released directly into the
upper Yakima River (12 sites between RM 155 and 200) on April 13,
1987. All fish released in 1987 were coded-wire tagged, and
approximately 13% of the pond fish and 12.6% of the fish released
directly into the river were freeze branded.
Counts of branded hatchery smolts captured at Prosser smelt
trap were used to evaluate freshwater survival of both groups of
fish. Based on brand recoveries alone the relative survival of
each group was calculated. Total estimated passage of each group
yielded absolute survival rate estimates to Prosser. Snolt to
18
adult return rates of these two groups will be determined from the
1987, 1988, 1989 and 1990 captures of tagged fish in the ocean,
mainstem Columbia River fisheries, the tribal dipnet fishery on
the Yakima River, collections at Roza Dam, and from carcass
recoveries on the spawning grounds.
19
5.2.2 BROOD SIWK EVALUATIONS
Hatchery spring chinook introduced into the Yakima River from
1958 to 1987 have come from numerous sources and stocks (Table l),
although, as previously mentioned, their contribution to the
genome of naturally spawning Yakima River fish has probably been
minimal. An experimental brood stock program was undertaken in
1984 and continued in 1985 to evaluate the benefits of using
spring chinook from the Yakima River as a source of gametes. The
purpose was to culture indigenous fish and to determine the
optimal stock for enhancement programs.
The best stock for enhancement programs will be determined by
a comparison of returns of adult fish from four release groups:
(1) a pond-acclimated group of hatchery-reared "hybrids" (Yakima
River males crossed with Leavenworth Hatchery females), (2) an
acclimated group of hatchery-reared "natives" (Yakima males
crossed with Yakima females), (3) an acclimated group of pure
hatchery smolts (Leavenworth males crossed with Leavenworth
females), and (4) a group of pure hatchery smolts released
directly into the river. Groups l-3 were allowed volitional
release from an acclimation pond in the upper Yakima River. These
groups will be used to determine if cultured fish that are the
progeny of Yakima River spring chinook have a greater success in
returning to the Yakima River than do non-indigenous stocks. The
fourth group will be used as a control on the value of acclimating
spring chinook in ponds for various periods before allowing
volitional release. Returns from group fOUr Will be COmpred
directly to group three.

5.2.3 ADULT HATCHERY RETURNS
Fourteen groups of adult hatchery fish returned to the Yakima
River in 1987. Coded-wire tags were recovered from four sources;
the Yakima Indian Nation Zone 6 ceremonial and subsistence fishery
in the Columbia River, the Yakima dip net fishery, the spawner
surveys and carcass recovery surveys in the Naches River, and f ram
the adult trap at Roza Dam. All tags recovered were expanded by
the sample rate (fish sampled/total number of fish caught for a
fishery or carcasses -pled/total number of spawners esttited in
each river for spawner surveys) and by the mark rate or coded-wire
tag retention rate.
Survival rate for hatchery smelt to adult was calculated hy
dividing the total expanded return of adults from each release by
the estimated passage of smelts by Presser from that release. The
expanded return numbers were also divided by the total number of
smolts released in each group to obtain a hatchery planting to
adult survival rate.

6.0 RESUL'IS AND DISCUSSION
6.1 NA'IURAD PROIXJCI'ION
6.1.1 SURVIVAL To EMEKENCE SIUDIES
Results of survival to emergence studies will not be
presented due to extremely high spring runoff preventing data
collection during much of the emergence period.
6.1.2 WINTER DISIRIBVTION SISJDIES
Electroshocking studies were conducted from October 23, 1986
through January 8, 1987 to determine the instream movement,
distribution, and habitat selection of spring chinook juveniles
during the winter. Results showed that (1) fish found above Roza
Dam (RM 128) were generally smaller (mean fork lengths ranged from
92 to 97 mm) than fish found below Sunnyside Dam (RM 104), where
mean fork lengths ranged from 95-118 mm; (2) Fish above Roza Dam
were generally associated with instream cover- under large
substrate, root wads, and undercut banks; whereas fish below
Sunnyside Dam were generally observed near the stream bottom in
riffles and runs with slow velocities (Table 2).
A total of 19,867 wild spring chinook juveniles were branded
as they moved downstream past Wapatox DBTI between October 22 and
Decenbar 3, 1986 (see section 6.1.4). Iwenty-four brand recoveries
from wild spring chinook released atwapatox smelt trap (RM 17)
23
were sr&? between sunnyside Dam (RM 104) and the confluence of
Satus Creek (RN 70). Though it's not known what portion of
branded fish moved from the Naches River into the Yakima River,
these results indicate that fish collected in the fall
outmigration at Wapatox are moving a substantial distance
downstream into the lower Yakima River in a relatively short
period of time. Three fish were found 63 miles downstream from
Wapatox Dam only nine days after being released.

6.1.3 PROSSRR SMOLT TRAP
mlt outmigration was estimated from a logistic relationship
between percent river diversion and percent entrainment (Fast et.
al., 1985). A new logistic relationship was fit to data from test
releases made in 1984, 1985, 1986 and 1987. This relationship was
used to estimate 1987 outmigration and to "re-estimate"
oubnigration for 1983-1987 (Appendix B of the 1986 BPA annual
report). Test releases will be made throughout the duration of the
project. The diversion-entrainment relationship will be refined
and the outmigration of previous years reestimated on a yearly
basis.
6.1.3.1 Winter Movement
Prosser smolt trap was operated November 1, 1986 through
February 28, 1987 (estin-ated passage was interpolated for the two
periods 11/l-13 and 2/10-28) in an attempt to determine the number
of juvenile spring chinook moving downstream past Prosser Dam
during the winter months. The estimated outmigration of juvenile
spring chinook was 78,348 (Table 3). Spring chinook outmigrants
branded at Wapatox in the fall of 1986 represented 7.6% of this
total.
The mean length, weight and condition factor of unbranded
chinook all declined slightly from November through January. In
February the mean length and weight, but not the condition factor,
increase substantially (Table 4). Mean length and weight figures

for unbranded chinook were significantly greater (protected LSD,
G-0.01) than comparable figures for branded Wapatox chinook in
each of the four months monitored. The mean monthly condition
factor of unbranded chinook was also greater than the mean
oondition factor of branded Wapatox chinook in all months but
February, although the differences were significant only in
December andJanuary.
The estimated outmigration from November 1 through February
28 of Naches River juvenile spring chinook branded at Wapatox was
1,736 fish. This represents 8.7% of the total number of fish
branded and released at Waptox. It was estimated from expanded
data that 41.1% of the branded Wapatox fish migrated past Prosser
during the winter (November 1 - February 28), while the remainder
outmigrated as spring smolts.
Based on the estimated smolt outmigration of 251,975 this
spring, the number of total spring chinook juveniles outmigrating
past Prosser from November 1 through February 28 (57,803)
constituted 18.7 percent of the total brood year production. It
should be noted that this figure is conservative since the trap
was not in operation through parts of October, November and
February. These winter outmigrants could represent a significant
contribution to total production.
Previous estimates of egg to smelt survival for spring
chinook in the years 1983-1986 (Fast et. al., 1986) do not include
winter outmigrants and thus probably underestimate smelt
production. This winter's outmigration of 57,803 spring chinook
will boost the total egg-to-outmigrant survival rate about 24
29
percent, from 4.16 to 5.45 percent.
Even with current knowledge of the spring outmigration, the
long-term seasonal distribution of outmigrants will remain
speculative until the contribution of winter fish to total brood
year production has been determined. The winter run contribution
to total smolt production varies both among rivers and between
years in other Nortiest basins. In the L&i River in Idaho the
winter run comprises a fairly constant 50 percent of the total
(Bjornn, 1971) whereas in the Warm Springs River in Oregon, the
relative sizes of the winter and spring runs vary dramatically
from year to year (Stainbrook et. al., 1985).
It would appear that winter outmigrants of spring chinook
originate in all parts of the Yakima system, or at the least, not
exclusively from the Naches River. Of the 19,867 spring chinook
branded and released at Wapatox the fall of 1986, an estimated
1,736, or 8.7 percent, subsequently migrated to Prosser. The
recovery rate of branded fish should have been much greater if the
majority of fish observed at Prosser were leaving the Naches
River. Furthermore, there was a highly significant size
difference between branded (Naches River) and unbranded chinook,
with the Naches fish being 7 to 10 percent smaller than unbranded
fish. This size difference implies that the larger fish originate
in the upper Yakima.
There are two pieces of evidence to suggest that in the main
river, larger chinook undertook winter migrations while smaller
chinook remained in upriver rearing areas. First, data collected
while sampling the Yakima River in an electroshocking boat between
30
October 23 and January 8 indicated that smaller fish were found
above Roza Dam (Rm 128) than below (see section 6.1.2). Mean fork
lengths for the upriver fish ranged from 92-97 mm whereas mean
length of downriver fish ranged from 95-118 mm. Upriver fish were
generally found under large substrate or mng undercut banks and
root-wads. Downriver fish were generally found on the bottcrn of
slow runs and riffles. Second, the mean length of chinook branded
at Wapatox was significantly less than the mean length of
unbranded fish at Presser. Either significantly more small
branded fish died in route to Presser, or all fish grew 12-16 mm
betweenOctober and Pebruary9. While none of these possible
explanations can be dismissed, these explanations are relatively
unlikely in winter.
6.1.3.2 Spring Movement
A total of 451,370 salmonids were counted at Prosser smelt
trap March 1 through July 31, 1987. The total catch included
139,384 wild spring chinook, 95,505 wild fall chinook, 25,227
hatchery spring chinook, 50,546 hatchery fall chinook, 43,419 wild
steelhead, 10,825 hatchery steelhead, 511 hatchery rainbow trout
and 85,953 hatchery coho.

smolt outmigration occurred April 22-30, when 90,569 smolts
outmigrated (Figure 2). The date of median passage was April 23,
1987.
The estimated egg to smelt survival for wild spring chinook
was 4.16% (Table 6). This was calculated strictly upon the
estimated spring outmigration in relation to estimated egg

Mean fork length of wild spring chinook in the months April
through June was 130 mm, 123 rrun and 123 rrrn respectively (Table 7).
Mean monthly condition factors for the same time period ranged
from 10.8 to 11.5.
The estimated number of branded, wild spring chinook release
atwapatox (released 11/8/86 - 12/3/86) and later captured at
Prosser was 2,485 for the period March 1 through July 31. This
represented 12.5% of the total number released. With the winter
fish figured in, the overall estimated survival rate was 21.2%.
The percent of wapatox branded fish migrating to Presser in the
winter compared to the spring was 41.1% and 58.9% respectively.
6.1.3.4 Distinguishing Spring from Fall Chinook
Length frequencies and scale analyses were used to
differentiate spring and fall chinook outmigrants. Monthly length
frequencies of wild chinook sampled in 1987 are depicted in
Figures 3 and 4. Lengths are bimodally distributed in April and
May I with fall chinook comprising the first mode and spring
chinook the second mode. Fall chinook comprised most the smelt
outmigration in June and July (Figure 4).
Explicitly, the number of wild fall chinook migrating past
Prosser Dam in a given week was estimated as follows:
i=b
Nj (Li, j) (Fi, j) = Nf,j equation 1.
i=a
where a and b are length increment bounds, with "a"
representing "less that 40 nun,", "b" representing
35
"greater than 199 m", and with intervening steps of
mW-(40044,45-49,...,195-199);

6.1.3.5 Hatchery Releases
In 1986, survival to Prosser was monitored both by counting
freeze-brands (ten percent of total were marked) and by reading
coded wire tags extracted from sacrificed fish. A total of 178
coded wire tags were taken from unbranded, ad-clipped hatchery
chinook in 1986; results are presented in Table 8.
A Chi-quare test of homogeneity was performed between the
recoveries of CWT tagged fish to freeze branded fish, for the
various release groups. The Chi-Square statistic was rejected,
indicating that between the various release groups, for CWT tagged
and freeze branded fish, recoveries were not porportional. The
Chi-Square statistic for the 1986 data was 146 (chi-square
critical, =.05 was 12.6). It was determined that a large
portion of the Chi-Square statistic was generated from the
September-85 release group and the chi-Square analysis was
recalculated excluding this group. The new Chi-auare statistic
was 19 (Cl&Square critical, =.05 was 11.1). Homogeneity was
still rejected, however most of the lack of homogeneity is
explained by the September-85 release group. This is depicted in
Table 8 where the ratio between CWT tagged smolts and freeze
branded smolts, for the September-85 group, for percent recovered
was 5.0, while the remaining groups were much closer to 1.0.

6.1.3.6. Effect of Acclimation and Volitional Release on
Survival.
Mary's pond on the Yakima River (RM 192) was used to
acclimate the 1987 smelt releases. The same 12 sites on the upper
Yakima (median release point RM 181) used since 1983 were the
release sites for non-acclimated fish. Three groups of spring
chinook were acclimated in 1987: Leavenworth National Fish
Hatchery (LNFH) smolts, "hybrid" smolts (progency of LNFH females
and native Yakima males) and hatchery-reared native smolts. Only
LNFH hatchery smolts were used in the non-acclimated group.
Acclimated groups were moved to Mary's pond over the period
March 19 through March 23. Fish were allowed to volitionally move
out of the pond April 13. This was also the same day the trucked
smolts were released into the river. However it should be noted
that smolts were counted at Prosser as early as April 8,
indicating that fish were escaping from the pond prior to formal
removal of the block-net at the pond outlet.
41
A total of 50,113 norracclimated hatchery spring chinook, of
which 5,040 were branded, were released in 1987. Release figures
for acclimated hatchery smolts, hybrid smolts and native smolts
were 50,519 (5,040 branded), 56,841 (5,240 branded) and 52,392
(5,640 branded). Based on recoveries of branded fish at Prosser,
percent survival for non-acclimated hatchery fish was 38-5 and the
relative percent survival for acclimated hatchery, hybrid and
native smelts was 3.7, 2.8 and 10.6 respectively (Table 9).
A number of problems occurred which made it impossible to
obtain an exact count of the smolts that migrated from the
acclimation pond in 1987. An unknown number of fish were consumed
by an otter that was observed in the pond one week after the
smolts were planted (it was removed shortly thereafter). In
addition, the water level in the pond dropped below the outlet
elevation during the outmigration period due to the river flow
being so law that insufficient groundwater seepage occurred to
maintain a normal water level. This event prevented an
undetermined number of fish from emigrating. Also, a malfunction
of the electronic counter placed at the pond outlet precluded
obtaining an accurate count on the number of smolt that
outmigrated from the pond. Figure 6 presents the cumulative
percent outmigration for the four qroups. The earliest date of
median passage for any of the four groups was April 25, for the
acclimated hatchery group. Its mean migration rate to Prosser was
10.3 RM/day. Dates of median passage for the remaining three
groups; nor+acclimated hatchery, acclimated hybrid, and native
were April 27, April 30 and May 2, and mean migration rates were
42
10.3 RM/day, 8.5 M/day and 7.6 RM/day respectively. Despite
having the slowest migration rate, the acclimated native smolts
had the highest survival rate.

6.1.4 WAPATOX SKILT TRAP
Wapatox smolt trap operated until December 2, 1986 when the
screens were removed from Wapato Diversion Canal due to icing
conditions. A monthly summary of the estimated number of spring
chinook outrnigrants in the fall of 1986 is presented in Table 10.
The estimated passage of spring chinook pre-smolts in October and
November were 8,707 and 48,779 respectively. The highest period
of outmigration occurred November 18 through December 1 when
45,155 pre-smolts were estimated to have passed Wapatox. High
stream discharge may account for this. Stream discharge increased
from a mean of 438 cfs for the five preceeding weeks, to a mean of
1,236 cfs during this time period.
The October and November size distributions are presented in
Figure 6. Mean monthly fork lengths in October and November were
94 and 95 mm, respectively.
Monitoring of the smolt outmigration began April. 1 when the
screens were installed into the Wapato Diversion Canal. A monthly
summary of the estimated number of spring chinook outmigrants in
1987 is presented in Table 10. Estimated spring chinook smolt
outmigration in April, May and June was 13,561, 2,335 and 245
respectively. Total estimated outmigration past Wapatox was
16,141 smolts. Estimated pre-smolt outmigration in July, August
and September was 608, 1,158 and 3,464 respectively.
The estimated weekly catch of spring chinook is presented in
Table 11. The week of highest estimated outmigration was during
the first week of operation April l-7, when 4,123 smolts
46
outmigrated. This represented 27% of the total estimated
outmigration. Median passage date was April. 18.
Monthly size distributions of spring chinook smolts are
presented in Figures 7, 8 and 9. Mean monthly fork lengths in
April, May and June were 94, 97 and 107 mm, respectively. Mean
lengths of pre-smolts in July, August and September were 79, 82
and 87 mm, respectively.

6.1.5 ADULT REIURNS
In 1987 a total of 3,683 adult and 335 jack spring chinook
salmon returning to the Yakima River were counted at Prosser fish
ladder at RM 48 (Tables 12 and 13). This gives a total of 4,018
salrrron returning to Prosser Dam (Table 15). The raw daily fish
counts for Prosser Dam are presented in Appendix Tables A.1
through A.4. The mean dates of passage were May 12 and May 16 for
adults and jacks respectively. An additional 372 fish were
estimated to have been caught in the Yakima River subsistence
dipnet fishery below Horn Rapids and Prosser Dams (Table 15).
Therefore, total return to the Yakima system was 4,390 spring
chinook salmon (Table 16).
Spring chinook were counted at Roza Dam from May 1 to
September 30, 1987. Passage at Roza Dam was 1,610 adult and 67
jack spring chinook for a total of 1,677 wild fish (Tables 18, 19,
and 20). A total of 245 adult and 9 jack hatchery spring chinook
were collected at Roza Dam to recover the coded wired tags for
release group identification. An additional 174 fish were
harvested between Prosser and Roza Dams in the subsistence dipnet
fishery (Table 15). Daily raw counts of fish passage at Roza Dam
are presented in Appendix Tables A.5 through A.9. The median
dates of passage at Roza Dam were May 29 and May 26 for spring
chinook adults and jacks respectively.
A summary of adult and jack returns to each of the dams,
harvest belcrw and above Presser, and the number of fish available
to spawn in the Yakima and Naches Rivers is presented in Table 20.

The spring chinook redd counts from 1981 to 1987 are
presented in Table 21. These counts were not part of the data
collected on the present spring chinook study but are important
for estimates of survival through various life stages and are
included in this report for that reason.
Upper Yakima Surveys: A total of 1,063 redds were reported
from surveys on the upper Yakima. A total of 923 were above Roza
Dam and ah additional 140 were discovered in the area between Roza
Dam and Selah Bridge.
The number of chinook escaping past Roza was 1,677; the
number of redds was 923. The resulting statistic was 1.82 fish
per redd. There is no accounting for pre-spawning mortality by
this method. Consequently, 1.82 does not necessarily reflect the
average number of fish observed on a redd on the spawning grounds.
Naches Survevs: There were a total of 677 redds found on the
Naches River in 1987. This represents a decline in the redds
counted on the Naches system from 1986. Substantial increases
were observed in nearly all established spawning areas over the
1985 spawning season when the spring chinook escpapment was
similar to this years escapement.

6.1.6 ESTIMATES OF SURVIVAL THRCUGH VARIOUS LIFE SIXES
6.1.6.1 Egg to Fry:
Survival from egg to fry was discussed extensively in the
survival to emergence sections of the 1985 and 1986 annual
reports. The survival from egg to emergent fry was calculated to
be 59.6% which is the mean of the 62.5% estimate in 1985 and 56.7%
in 1986. As discussed earlier the 1987 studies were terminated by
high spring runoff and extensive bedload sediment trapped in the
redd cap nets.
Total egg deposition in the Yakima system from 1981 to 1987
is presented in Table 23. Wal. egg deposition was calculated as
the sum of three subareas: the upper Yakima, the American River,
and the remaining Naches system due to different mean size of
females in each of these areas. The mean fecundity as calculated
from the length fecundity model and the mean length of females
measured in each subarea in 1985 was 3,908 eggs/female in the
upper Yakima, 6,198 eggs/female in the American River and 5,150
eggs/female in the rest of the Naches system.
The total number of fry produced from the egg deposition in
1981 to 1987 is reported in Table 23. This estimate is based on
the current 59.6% egg to fry survival rate which is the mean of
the 62.5% estimate in 1985 and the 56.7% from 1986.

6.1.6.2 Egg to Snolt:
The egg to smolt (Se,) survival was calculated as the number of
smolts estirrated to outmigrate past Prosser divided by the total egg
deposition for their year class as calculated in Table 23. The egg to
smolt survival from egg deposition for the brood years 1981 to 1985 and
corresponding smolt outmigration years of 1983 to 1987 are presented in
Table 24.
This mean percent survival from egg to smelt of 4.9% is much lower
than the 10.7% (range from 5.4 to 16.4) reported by Major and Mighell
(1969). Bjornn (1978) evaluated natural production of spring chinook in
the Lemhi River, Idaho, and over an 8-year period found that survival
from egg to migrant smolt averaged 9.8% (range 4.0% to 15.9%). This is
also much higher than the five year mean of 4.9% we found. He
considered the level of spawning escapents to the upper Lemhi River

low during the study years, thus underseeding may have resulted in
maximum survival rates for juvenile chinook in that system.
Several other studies conducted on mid-Columbia tributaries
had survival rates similar to those observed in the current study.
In the Deschutes River, Oregon Johasson and Lindsay (1983) found
an average egg-to-migrant survival rate of 3.5 percent (range 2.3%
to 5.5%) for their spring chinook smolts. These were primarily
yearling spring migrants but also included fall (age 0) migrants.
An egg-temigrant survival rate of 5.2% (range 3.6% to 6.7%) was
found for spring chinook in the John Day River, Oregon, (Lindsay
et al., 1981). These percentages were based on yearling spring
migrants only.
In 1986-1987 were we able to make an estimate of the winter
outmigration in the Yakima River because the screens were left in
the canal due to the milder than average winter. The winter
outmigration increased the total 1987 smolts outmigration from
251,975 to 330,323 smolts. The new Chandler Canal screens will
allow winter sapling to occur xr0re regularly in the future.

6.1.6.3 Fry to Snolt:
An estimate of the survival from fry to snolt (Sfs) based on
the fry production (Table 23) and smolt outmigration at Prosser
for the brood years of 1981 to 1985 is reported in Table 25.

6.1.6.4 Snolt to Adult:
The smolt to adult (Ssa) survival based on the 1983 smolt
outmigration estimated at Prosser and the 1984 return of jacks (3
year old fish), the 1985 return of four year old adults, and the
1986 return of five year old adults to the Yakima River is
reported in Table 26. It was estimated that 6,012 wild three,
four, and five year old fish returned from an estimated smolt
outmigration of 135,548 fish in 1983.
The smolt to adult (Ssa) based on the 1984 smolt outmigration
estimated at Presser and the 1985 return of jacks and the 1986
67
return of four year old adults and the 1987 return of five year
old adults to the Yakima River is reported in Table 29.
The smelt to adult (Ssa) based on the 1985 smolts
outmigration estimated at Presser and the 1986 return of jacks and
the 1987 return of four year old adults to the Yakima River is
reported in Table 30.
This estimated rate of survival. from smolt to adult is also
subject to error due to our estimation of total outmigration. We
are quite confident in the smelt outmigration estimation procedure
for Prosser (Section 6.1.3). However, from the recant findings at
Wapatox smolt trap indicating an extensive fall outmigration, and
the premliminary findings at Prosser smelt trap this past winter
(see section 6.1.3.1), there may be a large outmigration of
pre-smolt spring chinook in the months when the Chandler Canal
smolt trap is inoperable due to screen removal.

6.2 HATCHERY OPERATIONS
6.2.1 CUTPLAWINS SJJJDIES
6.2.1.1 %olt releases
To evaluate the effectiveness of rearing and releasing hybrids and
acclimating fish in earthen ponds and then allowing for a volitional
release as smolts, three groups of spring chinook smolts were released
from Mary’s pond at RM 192 on the Yakima River and a forth group was
transported from Leavenworth National Fish Hatchery and scatter-planted
directly into the upper Yakima River between RM 155 and 200. The
release data for the 1987 acclimation pond and river-released groups of
smelts is presented in Table 29.
Similar releases were made from Nile Springs pond and the upper
Yakima River in 1983 and 1984 and from Mary's pond and the upper Yakima
River in 1985 to compare acclimation ponds vs. direct river releases.
The 1986 release groups represented the first time the wild x wild and
wild x hatchery hybrids were released. The 1987 release groups were a
repetition of the 1986 releases. The survival of these release groups
to Presser is discussed extensively in the snolt trapping section of
this report. The 1983 release groups returned as six year old adults in
1987 and the 1984 release groups returned as four year old adults in
1986 and five year old adults in 1987. The 1985 release groups returned
as four year old fish in 1987. Their survival rates will be discussed
in the Hatchery Adult Return section of this report.

6.2.2 BROOD SIEK EVALUATIONS
An experimental brood stock program was undertaken in 1984
and continued in 1985 to evaluate the effectiveness of using
spring chinook adults from the Yakima River as a source of gametes
for hatchery reared fish in an attempt to maintain the genetic
components indigenous to the Yakima Basin. Crosses were made to
obtain four different release groups; wild males and wild females,
wild males and hatchery females, and two groups of hatchery males
and females. The first three groups were released in acclimation
ponds and the fourth group was released directly into the Yakima
River and compared with sunrival of group three - a continuation
of the acclimation pond vs. river release study. The required
crosses were made in 1984 and 1985 from Yakima River brood stock
adults taken from the Roza adult trap. The hybrids were reared at
Leavenworth National Fish Hatchery and released as smolts. The
first releases, the 1984 brood year products, were made from
Mary's pond and the upper Yakima in 1986. The resulting progeny of
the 1985 crosses were released at the same locations in 1987.
Survival of each release group was calculated at Prosser smolt
trap for smolt survival. The survival to returning adults will be
determined for each group through 1990 when the five year old
adults from the 1987 smolt releases return to the river.
6.2.3 ADULT HATCHERY RETURNS
Spring chinook adults from fourteen different hatchery
74
release groups were recovered in 1987. These fish were identified
by the coded wire tags recovered in the Yakima Indian Nation Zone
6 ceremonial and subsistance fishery, the Yakima River ceremonial
dipnet fishery, from spawning ground surveys and carcass recovery
surveys conducted on the Yakima and Naches River systems in
August, September and October of 1987, and from the adult trap at
Roza Dam. A total of 149 fish were inspected for adipose fins and
coded wire tags in the Naches River in 1987. All fish passing
Roza Dam were inspected for adipose clips. Any clipped fish were
sacrificed to increase the the recovery of coded wire tags. Table
30 presents the release data for all hatchery groups that could
possibly return to the Yakima system as three, four, five or
six-year-old fish in 1987 (two six year old adults were found in
1987).

The 1987 adults returning from the 1983 upper Yakima
release groups were six-year-old fish, and complete the data
necessary to calculate the smolt to adult survival rate for
these two hatchery release groups.
An analysis of the 1983 upper Yakima River release group
indicates that 2 six-year-old adults returned in 1987, 12
five-year old adults returned in 1986 and 31 four-year-old fish
returned in 1985. The total estimated adult return was thus 45
fish. There were 97,725 smolts released in the upper Yakima in
1983. This gives a "smelt-at-release" to adult survival rate of
0.05%. It was estimated that 20,131 of these snolts survived
passage to Prosser Dam in 1983. The smolt-at-Prosser to adult
survival rate was thus 0.22%. This compares to a
"smelt-at-release" to adult survival rate of 0.08% and
"smelt-at-Presser" rate of 0.2% for the Nile pond acclimation
release group.
Survival rates for smolt-at-Prosser to adult are almost
identical between the acclimated and nowacclimated 1983 release
groups. The survival rate from release site to Prosser,
however, was almost twice as great for the acclimated fish
(38.5%) as for the non-acclimated fish (20.6%). Thus,
acclimation and volitional release apparently increased the
relative fitness of acclimated smolts, perhaps by allowing
recovery from the stress of handling and transportation and/or
the development of adaptive behavior patterns (e.g., predator
avoidance responses).
In 1987 we recovered coded wire tags from five year old
77
fish frcm both the 1984 release group at Nile Springs pond and
the 1984 upper Yakima River release group. An expanded total of
21 fish were estimated to have returned from the Nile Springs
acclimation pond release. This give a total of 40 returning
adults (19 in 1986) for this release group. The survival from
smolt at release (29,636 smolts) for this acclimation pond
release was therefore 0.13%. It was estimated that 16,063 or
54.2% of these smolts survived to Prosser smolt trap. This gives
a "smelt-at-Presser" to adult survival rate of 0.25%.
A total of five upper Yakima River release group adults
were recovered as five year old adults in 1987. Added to the 12
adults returning from this release group in 1986 gives a total
of 17 adults from the river release.
A total of 45,552 smolts were released in this experimental
group. That gives a 'Ismolt-at-release" survival rate to adult
of 0.04%. These smolts survived to Prosser at 32.7% rate which
give 14,896 snolts and a Wsmolt-at-Prossern to adult survival
rate of 0.11%.
Five other release groups had more than three returning
adults in 1987. All five groups were from the 1985 smolts
outmigration and thus were returning as four year old adults in
1987. These five release groups were the 1984 pre-smolt release
groups of June fry (25 adults returned), September pre-smolts
(35 adults), and November pre-smelts (43 adults), and the 1985
smolt release from ~arys pond (61 adults) and the upper Yakima
River releases (32 adults). Since each of these groups could
have five year old adults return in 1988 the analysis of percent
78
molt to adult survival will not be undertaken in this annual
report.
