ADULT SALMON INVESTIGATIONS MAY -OCTOBER 1984 By: Bruce M.Barrett Frederick M.Thompson Susan N.Wick Prepared for: Alaska Power Authority 334 W.Fifth Avenue,Second Floor Anchorage,Alaska 99501 JUNE 1985 .... PREFACE The Susitna River is the largest watershed in the Cook Inlet basin encompassing about 19,400 square miles from its origin in the Alaska Mountain Range to its discharge into Upper Cook Inlet (Figure A). / / I I I I1..,--___ \, '............,....,,,, , "... .......,'.......,, \ \ I I I,,,, 0/ ~ '""..........._-------" RtIIl.Rlw ..line """ Figure A.Susitna River drainage,1984. The Alaska Power Authority (APA)proposes construction of two hydroelec- tric dams at Watana and Devil Canyons on the upper Susitna River (Figure A).The Alaska Department of Fish and Game (ADF&G)has been contracted by APA to assess the fi shery resources that mi ght be impacted by the proposed hydroelectric project.The APA-ADF&G contract,initiated in November 1980,is still in effect. Thi sis one of a series of ADF&G reports for 1984 that wi 11 be submi tted to APA.This document addresses the adult anadromous fish inves- tigations contracted for the Susitna River open water period of May through October,1984 and specifically covers the following Pacific salmon species: Pacific Salmon Oncorhynchus ~.

- -ij - 1.0 OBJECTIVES The fourth consecutive year of study of the Susitna River adult salmon populations in association with proposed hydroelectric development at Watana and Devil Canyon was completed in 1984.The primary emphasis of the 1984 study were to quantify mainstem escapements and to define spawning locations.More expl ici tly,the objectives,by ri ver reach, were: A.Lower River (Intertidal at RM 0.0 to the Chulitna River confluence at RM 98.6). 1.define the abundance,timing and stock characteristics of sockeye,pink,chum and coho salmon escapements to the Susitna River at Flathorn (RM 22)and Sunshine (RM 80) stations and into the Yentna River (RM 28)at Yentna Station (TRM 04);additionally,evaluate the same parameters for chinook salmon at Sunshine Station; 2.define timing,distribution and extent of salmon spawning in Susitna River slough,main channel,side channel and stream mouth habitats upstream of Yentna River. B.Middle River (Chul itna River confluence at RM 98.6 to upper Devil Canyon at RM 161.0). 1.defjne the abundance,timing and stock characteristics of chinook,sockeye,pink,chum and coho salmon escapements to the Susitna River at Talkeetna (RM 103)and Curry (RM 120)stations; 2.define timing,distribution and extent of salmon spawning in main channel,side channel,stream and slough habitats;additionally,to determine the average resident time (observed residence)of sockeye and chum salmon in middle-reach sloughs. 1 2.a ~1ETHODS 2.1 Main Channel Escapement Monitoring In 1984,salmon escapements were monitored at five mainstem locations on the Susitna and Yentna rivers (Figure 1).In the lower Susitna River reach,a tagging site was operated at Flathorn Station,a sonar site at Yentna Station on the Yentna River and a second tagging site at Sunshine Station between Montana Creek and the George Parks Highway bridge.In the middle Susitna River reach,a tagging station was operated at Ta "lkeetna Stati on and another at Curry Stati on.With the excepti on of Flathorn Station,a new tagging site this year,the other four monitoring stations were at the same river mile locations in 1984 as in 1981 through 1983. The five lower-and middle-river escapement monitoring stations in 1984 were operated according to the schedule in Table 1.Flathorn and Sunshine stations each had four fishwheels in operation.At Yentna Station,two side scan sonars (SSS)and two fishwheels were run concurrently.In the middle reach,four fishwheels at Talkeetna Station and two fishwheels at Curry Station were used.The specific placement sites of the 16 fishwheels and two sonars at the five sampling stations can be found in Appendix 2. -. Table 1.Operation schedules at main channel Susitna and Yentna rivers escapement monitoring stations,1984. The two sonars operated in 1984 at Yentna Station were 1980 Model Side Scan Sonar Counters (Bendix Corporation).The sonar installation and operating procedures were in accordance with the manufacturer1s operational manual (Bendix Corporation 1980).Except for occasional 2 SUNSHINE STATION Figure 1.Susitna River basin map showing fieJd stations and major glacial streams.1984. 3 - - - - - - - - heavy-debris flow periods associated with extreme high water,the two sonar counters at Yentna Station were run continuously,24 hours per day,through the season.The two fishwheels,one near each sonar off the north and south Yentna Ri ver banks,were operated a mi nimum of 12 hours daily during the season for apportioning the sonar counts by species and for tag recovery data from Flathorn Station.Detailed sonar monitoring and apportioning methodology is described by Barrett et al. (1984)• All fishwheels were designed by AOF&G Su Hydro staff (ADF&G 1981,1982). The fishwheels at Flathorn,Sunshine,Talkeetna and Curry stations were run 24 hours per day except for occasional down time for maintenance, debris problems and high catches that exceeded manpower capabilities. Each fi shwheel was checked four or more times daily.Salmon catches were tagged and released,except for the following,which were not tagged: fish that visually appeared lethargic or stressed; post-spawning condition fish; fish previously tagged; 90%of the pink salmon at Flathorn and Sunshine stations,and 50%of the pink salmon caught at Talkeetna and Curry stations; chinook salmon at Flathorn Station,and chinook salmon less than 351 mm in fork length at the other three stations. All recaptured fish were checked for species identification and tag type,color and number before being released. In 1984,two tag types were used.All chinook salmon were tagged with Petersen discs.The other species were tagged with Floy FT-4 spaghetti tags.The exception was at Curry Station where Petersen disc tags were used for all species.A percentage of the tags used at all the tagging stations were numbered to determine migrational travel time.The methodolo~y used to implant the Petersen and spaghetti tags can be found in AOF&G (1981). At each sampling station on the Susitna and Yentna rivers,an age,fork length and sex composition sample was collected daily for the following number of each species regardless of size: 1.chinook salmon--30 consecutiv·ely caught fi sh,except at Sunshine Station,where the sample was 30 consecutively caught fish from both the east and west bank fishwheels; 2.sockeye salmon--30 consecutively caught fish,except at Flathorn Station,where the sample was 30 consecutively caught fish from both the east and west channels; 4 3.pink salmon--30 consecutively caught fish; 4.chum salmon--20 consecutively caught fish; 5.coho salmon--20 consecutively caught fish. The procedures followed in 1984 for collecting salmon age,length and sex samples can be found in ADF&G (1982). On August 22,1984,25 cono salmon were collected at Sunshine Station for a fecundity study.The collection procedures used for sampling fecundity can be found in Barrett et.al.(1984). 2.2 Spawning Ground and Tag Recovery Surveys Drainage-wide surveys of pre-selected chinook spawning areas were conducted cooperatively by ADF&G Region II Sport Fish Division and ADF&G Su Hydro.The surveyed areas have been routinely monitored for chinook si nce 1976 (ADF&G 1981).The 1984 surveys were performed from hel i- copter,fixed-wing airplane,raft and by foot,depending on access. Between mi d-July and mi d-August,most lower-river areas were surveyed once and most middle-river areas were surveyed twice. The next two subsections outline additional 1984 salmon spawning ground and tag recovery survey work by ADF&G Su Hydro staff,specific to river reach. 2.2.1 Lower Reach The mouths of lower-reach streams listed in Table 2 were surveyed weekly for salmon presence (by foot.and occasionally by helicopter)from July 21 to October 7,1984.A II stream mouth"began at the confl uence and extended one-third mile into the reach. - - - l Table 2.Lower reach Susitna River stream mouths surveyed weekly from July 21 to October,7,1984.

The mouths of the streams listed in Table 2,and confirmed mainstem and slough salmon-spawning habitats in the lower reach were mapped and described in terms of channel morphology,substrate composition and ground water presence. Preci se evaluations of substrates at stream mouths were performed as time permitted using a McNeil sampler and sieves.Substrates were sampled for eggs by excavation with a shovel or backpack-mounted Homelite water pump and screen. 2.2.2 Middle Reach Salmon-spawning surveys were conducted between July 21 and October 14. Specific chinook surveys were made between July 21 and August 18 of all suspected middle-reach spawning streams.Each stream was generally surveyed twice by helicopter or on foot to the upper limit of fish migration. All sloughs and streams of suspected adult salmon use were surveyed weekly from August 6 to October 11.Sloughs were surveyed on foot over their entire distance,and streams to standard index markers. Exceptions were Indian River (RM 138.6)and Portage Creek (RM 148.9),in which the entire reaches accessible to salmon were surveyed.Three streams located in Devil Canyon:Cheechako Creek (RM 152.4),Chinook Creek (RM 157.0)and Devil Creek (RM 161.0)were similary surveyed. Observed residence data was taken for chum and sockeye at three-day intervals from slou;hs Moose (RM 123.5),AI (RM 124.6),8A (RM 125.1) and 11 (RM 135.3).Observers used polarized glasses and polarized 7 x 35 Bushnell binoculars to detect and identify tagged chum and sockeye from Curry Station.Observers recorded sighting date,tag number, species,location in the slough and activity of each tagged salmon. Main channels and side channels were surveyed weekly by helicopter fr0m August 27 to October 13.Criteria presented in Section 2.2.1 were used to identify spawning sites. Tag recovery surveys were conducted in conjunction with spawning ground surveys by recordi ng numbers of 1i ve tagged and untagged fi sh of each species. 6 Egg retention sampling of sockeye and chum salmon carcasses was conducted at sloughs during escapement surveys.The sample size was based on fish availability and time.An incision was made in the abdomen of each fish and retained eggs were counted by hand. 2.3 Data Analysis 2.3.1 Escapement 'Monitoring by SSS Counter The SSS counters operated at Yentna Stati on had a counti ng 'range of 60 feet,which was divided into 12 equal sectors.Counts for individual sectors were reg;stered hourly on a pri nter.The printer tapes were edited in the field and rechecked in the office to eliminate debris counts (Barrett et al.1984). The daily fish counts by each SSS counter at Yentna Station were apportioned by species based on the composition of the catch by the fishwheel operating on the same day off the same bank.When the daily fishwheel catch was less than 150 fish,the SSS counts were apportioned according to the cumulative fishwheel catch for the succeeding number of days required to reach a 150 fish threshold catch sample. 2.3.2 Tag and Recapture Estimates Salmon escapements to Flathorn,Sunshine,Talkeetna and Curry stations were estimated using the modified Petersen model by Ricker (1975).The exception was for jack chinook salmon measuring less than 351 mm. Barrett et al.(1984)discuss the procedure for calculating the jack chinook salmon escapements,the assumptions and suitability of the Petersen model and the calculation of the associated 95 percent confidence limits. 2.3.3 Escapement Timing Salmon escapement timings were calculated for each species by station based on fishwheel catches.Species migration at a sampling station was defined to have started,reached a midpoint and ended on the date when 5,50 and 95 percent of the cumulative station fishwheel catch-per-unit- effort (CPUE)was attained. Escapement timings by salmon species are presented graphically as fishwheel CPUE curves,smoothed by the von Hann linear filter method (BMDP 1981). 2.3.4 Age Samples •.T Standard scale analysis techniques (Clutter and Whitesel 1956)were used to determine the ages of migrating salmon.The Gilbert-Rich notation is used to describe salmon ages. 2.3.5 Slough Escapements Sockeye and chum ,salmon escapements to individual sloughs above RM 98.6 were calculated using spawner abundance data adjusted by average fish 7 - - -1 -observed residence (Cousens et ale 1982).Two exceptions to this method were:1)when a peak escapement count for a slough was less than 15 live and dead fish and 2)when only one spawning ground survey was made. Total slough escapements in these cases were calculated using the following formula: Ax=B (T) - where x =estimated escapement of Slough x A =sum of escapements to all sloughs having peak counts ~50 fish B =sum of peak counts of all sloughs having peak counts 250 fish T =single highest fish count at Slough x. - - Pink salmon escapements to sloughs above RM 98.6 were adjusted by multi plyi ng the peak 1ive and dead survey counts by a factor of 1.2. This correction factor assumes that 80 to 90 percent of the spawning population was present at the peak of the escapement count (Cousens et a 1.1982). 8 - 3.0 RESULTS AND DISCUSSION In 1984,the Susitna River supported an escapement of at least 5.4 million salmon,determined from Petersen estimates of sockeye,pink, chum and coho salmon reaching Flathorn Station and chinook salmon reaching Sunshine Station.The species composition was about 2 percent chi nook,11 percent sockeye,68 percent pi nk,15 percent chum and 4 percent coho salmon. The following subsections of this report will address the 1984 salmon migrations past five mainstem locations on the Susitna and Yentna rivers (Figure 1),and define where spawning occurred,emphasizing the Susitna River from the Yentna River to upper Devil Canyon.The reader will find the subsections formatted by species order and Susitna River reach.The species order is:chinook,sockeye,pink,chum and coho salmon.The river division is:lower reach and middle reach. 3.1 Chinook Salmon 3.1.1 Lower Reach 3.1.1.1 Main Channel Escapements In 1984,chinook salmon were intercepted late in the migration at Flathorn and Yentna stations.Monitoring operations commenced at those locations on June 29 and July 1,respectively.Historically most of the chinook salmon escapement has al ready moved through the Susitna River lower reach by these dates (ADF&G 1982).Chinook salmon daily fishwheel catches at Fl athorn and Yentna stations are 1i sted in Appendi x Tables 3-3 and 3-6.Chinook salmon SSS counts for Yentna Station ar.e in Appendix Tables 4-1 and 4-2. An estimated 121,700 chinook salmon reached Sunshine Station in 1984 (Figure 2 and Table 3).Less than four percent of those fish were jack salmon 350 mm or smaller (Table 4)and the remainder (96%)were chinook salmon over 350 mm (Table 5)•. Fishwheels at Sunshine Station intercepted 7,550 chinook salmon in 1984 (Table 6).Based on these catches,migration there began on June 9, reached a midpoint on June 21,and ended on July 6 (Appendix Table 3-11).Migration began and ended about four days earlier on the west side than the east side,based on differences in east and west bank fishwheel catches. At Sunshine Station most chinook going to the Chulitna River migrated along the west bank.Most of those going to the Talkeetna River passed Sunshine along the east bank.Middle Susitna River populations ran in about even numbers along both banks (Figure 3).These migrational differences were determined by comparing the ratios of east-tagged to west-tagged fish from Sunshine that later were found in the Chulitna and Talkeetna drainages and in the middle Susitna River (Appendix Table 6-4). 9 - - - CI oSc • 0..-",,- -0(1_..en CHINOOK SALMON o--"-'-"-~~""""""-"""'- 150 Sunshine Station (121,100 fish) ~ l~t Talkeetna Station (24,800 filh) .'~\~ It_'It'\,,-~o Curry Station (18,000 filh) Figure 2.Chinook salmon escapements by sampling stations.1984.

".,. Chinook salmon fishwheel catches at Sunshine Station are plotted in Figure 4.The curves generally reflect a bell-curve distribution, except for a six-day low period from June 13 through 19.River dis- charge levels during that period fluctuated dramatically from 54,000 cfs (June 13)to 93,000 cfs {June 17}to 71,000 cfs (June 19)(Figure 5). The reduced catch was probably due to those flow changes.In other studies,salmon responded to high water events by reducing their migration speed (ADF&G 1981 and Barrett et ale 1984). ,.,-----.---.--- / SUNSHINE STATION East Bonk ---- West Bonk ------------Smoothed by a +2b iC 4 CUftKative "Y.- - - ...... ,- 8 QI 6 QI..c :3: '"L.

Length,age and sex information collected from a sample of the chinook salmon escapement at Sunshine Station are summarized in Tables 7,8 and 9 and Figure 6.Based on scale analysis,the 1984 escapement at Sun- shine Station was comprised of three-to seven-year-old fish.The largest component was five-year-old fish (38%)(1979 parent-yea~ escapement),followed by six-year-olds (34%).The average chinook salmon length at Sunshine Station was 765 mm (Appendix Figure 5-1). Males averaged 150 mm shorter than females due to a higher percentage of males in the younger age classes (Table 7).Overall at Sunshine Station,males were equally as abundant as females (Table 9).However males were more abundant among the three-and four-year-olds,and females were more numerous in older age classes. 3.1.1.2 Spawning Areas In 1984,there was no evidence of chinook salmon spawning in the lower- river mainstem above the Susitna/Yentna River confluence (Appendix 1). Mainstem surveys were performed from August 21 through October 17,which was well after the peak spawning occurred in local streams.Addition- ally,fish-tagging crews at Flathorn,Yentna and Sunshine stations in June,July and early August saw no evidence of chinook spawning such as repeated surfacing of ripe fish or carcasses on gravel bars and shoals not related to washouts from known spawning streams. 14 - -~j 1 J 1 ))J )j ]j J 1 Table 7.Analysis of chinook salmon lengths,in millimeters,by sex and age class from fishwheel CPUE weighted escapement samples collected at Flathorn,Yentna,Sunshine,Talkeetna and Curry stations,1984.

There was no indication that stream mouths or sloughs in the lower reach served as spawning areas for chinook.These areas were surveyed weekly from July 21 to October 21 (Appendix 1). 3.1.2 Middle Reach 3.1.2.1 Main Channel Escapements In 1984,the chinook salmon escapement to the middle reach was an estimated 24,800 fish at Talkeetna Station and 18,000 fish at Curry Station (Tables 4 and 5).About one percent of the Talkeetna chinooks were jacks (~350 mm).At Curry,four percent were jacks.Approxi- mately 45 percent and 24 percent,respectively,of the escapements reaching those stations were milling fish that returned downstream and spawned.These percentages were determined by spawning ground counts conducted above the two stations (Section 3.1.2.2).Most of the chinook salmon that milled to Talkeetna and Curry stations subsequently spawned in the Talkeetna and Chulitna river systems (Appendix Table 6-4). Chinook salmon were abundant in the middle-reach mainstem for about 25 days in 1984.At Talkeetna Station,migration began on June 15 and - 18 - ended on July 12,with a mi dpoint on June 26 (Appendix Tabl e 3-14). Migration at Curry Station began on June 19,reached a midpoint on June 25 and ended on July 13. A plot of daily fishwheel catches at Talkeetna and Curry stations (Figure 7)indicates that there was a surge in chinook at those stations around June 19,1984.The increase in fish numbers can be attributed to a flow change in the Susitna River.On June 16,river flow at the USGS station at Gold Creek increased 9,400 cfs over the previous day to 40,600 cfs and continued to rise.On June 17,the flow peaked at 52,000 cfs.By June 19 the flow had receded to 33,600 cfs (Figure 8).At Talkeetna and Curry stations,fishwheel catches were relatively weak at about 0.4 fish per wheel per hour during the high flow event.When the flow decreased to near pre-flood levels,catches increased to about 1.6 fish per wheel per hour.

The 1984 chinook escapement at Talkeetna Station was comprised of three- to seven-year-old fish (Table 8).The majority were five-and six-year- olds.Average c.hinook length at Talkeetna Station in 1984 was 816 mm (Appendix Figure 5-2).Males averaged 90 mm shorter than females. Overall,male and female chinook were about equally abundant (1.1:1)at Talkeetna Station.However,males were more abundant than females among the three-and four-year-ol ds but 1ess abundant among the five-to seven-year-olds. At Curry Station,the 1984 chinook escapement was also comprised of three-to seven-year-old fish (Table 8).Five-and six-year-olds were dominant.The average length was 801 mm (Appendix Figure 5-3).Females averaged 140 ~n longer than males (Appendix Figure 5-3).Overall,males were more abundant than females (1.2:1).Males were more numerous in the three-and four-year-old age classes,but less numerous in the five- to seven-year-old age classes. 21 3.1.2.2 Spawning Areas In 1984,no chinook spawning was found in the middle-reach mainstem. Several chinook salmon carcasses were found on gravel bars in the mainstem in early August,but all were considered to be fish that washed out from nearby spawning streams. Chinook did not use middle-reach sloughs for spawning or milling in 1984 (Appendix 6).However,12 streams were used (Table 10).Nearly all the fish (96%)were found in Indian River and Portage Creek (Figure 10). Surveys of those two streams indicated that spawning commenced prior to July 25 and was completed by the end of August,with a peak the last week in July and the first week in August (Figures 11 and 12).

Spawning in middle-reach streams occurred from mid-July to mid-August (Appendix 6).The peak spawning occurred in the last week of July. In 1984,approximately 13,800 chinook salmon spawned in the middle reach,assuming that all spawning areas were surveyed and that a peak stream count represented about 52 percent of the spawning population 22 - "'"" - - CHINOOK SALMON - 7:S.9% - - -20.3% 1.3% )'il'f'~ ]) ~(5.<1<16 IlIn)80~,en ~~::E Rio!150 od:wa:: ~60en )"0 "~~\ 0 40., Z(1,<156 fish)0RMI40 ~ ~ CD a::ZO"'""p ~ -=s en C!-O ~0D (92 ,..h)PORTAGE CREEK (RM 148.9) INDIAN RIVER (RM 138.6) 4th of JULY CREEK (RM 131.1) Figure 10.The three major streams in the middle reach occupied by chinook salmon and the respective percent escapement based on peak counts,19B4.

At Sunshine Station,the migration of first-run fish was concentrated on the east bank with the two east bank wheel s catching 99 percent of the fish in 1984 (Appendix Table 3-7). First-run sockeye salmon were sampled at Sunshine Station to determine representative escapement age,1ength and sex compositi on (Tabl e 14). Nearly the entire 1984 escapement (96%)was five-year-old fish (1979 brood year)(Table 15).The remainder of the escapement (4%)included four-and six-year-old fish.Most of the returning first-run sockeye salmon had spent one winter in freshwater before entering the marine environment.The average length was 531 mm (Appendix Figure 5-6). Ma 1es averaged 34 mm longer than fema 1es.Overall,males were 1es s numerous than females (0.5:1)(Table 16). 3.2.1.1.2 Spawning Areas The first-run sockeye salmon that migrated past Sunshine Station in early June 1984 spawned in the inlet stream of Papa Bear Lake.The spawning extended from the creek mouth upstream about 1.5 miles and took place mainly over the last three weeks of July.Spawning probably peaked July 20.These fi ndi ngs are based on two escapement surveys conducted on July 14 and 26 (Table 17).On the first date,there were about 1,500 sockeye in Papa Bear Inlet stream that were just beginning to spawn and another 500 to 1,000 fish holding off the creek mouth in Papa Bear Lake.There were no sockeye carcasses in the creek other than several bear-killed fish.On the second date,most of the fish in the creek were in post-spawning condition,and there were no sockeye salmon observed holding off the stream mouth.

Yentna Station escapement was approximately 149,000 sockeye,represent- ing 25 percent of the escapement to Flathorn Station (Table 19).An estimated 130,100 sockeye,or 21 percent of the Fl athorn escapement, reached Sunshine Station (Table 18).Based on the estimated escapements to Flathorn,Yentna and Sunshine stations,roughly 300,000 sockeye spawned in areas of the Susitna River basin between RM a and Sunshine Station,excluding the Yentna River drainage.The four known sockeye spawning systems below Sunshine excluding the Yentna River are defined in Figure 17.Of these,the Fish Creek drainage is probably the most product i ve based on previ ous surveys (ADF&G 1982).Alexander Creek, Deshka River and Whitsol Lake drainages are minor sockeye salmon- producing systems (pers.comm.K.Delaney). 38 - - - - ..... - ....

Catch differences between station fishwheels can indicate fish migration preferences.At Flathorn Station,sockeye sa.lmon slightly favored the west channel over the east channel for migration.The west fishwheels intercepted 55 percent of the station sockeye catch,the east fishwheels 45 percent (Appendix Tables 3-1 and 3-2,and Figure 21). -oOIII-<~-S uS I TN A Figure 21.Migrational preference of sockeye salmon to the east and west channels at Flathorn Station,1984. At Yentna Station,sockeye salmon favored the south bank over the north bank for migration.The south bank fishwheel caught 92 percent of the station catch and the north bank fishwheel made eight percent of the catch.The same trend was observed wi th·the SSS counters at Yentna Station.About 95 percent of the apportioned sockeye salmon counts were logged by the south bank counter.At Sunshi ne Stati on,most of the sockeye migrated along the east bank.The east bank fishwheels caught 77 percent of the station catch while 23 percent was taken in the west bank fishwheels. 43 Tagged sockeye salmon released in the east and west channels of Flathorn Station were recaptured at Yentna,Sunshine,Talkeetna and Curry stations (Table 20).The recapture information indicated 73 percent of the sockeye salmon enteri ng the Yentna Ri ver mi grated past Fl athorn Station in the east channel.

Representative age,length and sex samples were collected from the 1984 sockeye salmon escapements to Fl athorn,Yentna and Sunshi ne stations. Most of the lower-reach escapement were four-and five-year-old fish (Figure 22).Nearly all had spent one winter in freshwater before entering the sea.Lengths at Flathorn averaged 519 mm,at Yentna 535 mm and at Sunshine 512 mm (Appendix Figures 5-4,5-5 and 5-7).The longer average at Yentna Station was due to a larger return of five-year-olds to the Yentna River than to the other stations.At all stations,males averaged from three to 30 mm longer than females.Males were slightly less abundant than females at Yentna (0.9:1)and Sunshine (0.7:1),but more abundant at Flathorn (1.5:1)(Table 16). 44 - ~I - - """,,, - ]J ))).--J »J ]j ~ 100 100 100 100 100 100 eo 80',80 80 80 r- 60 fl f1 f1 00]~6 °1 60l-t-~~zwUu~40 eJ 0: WQ.n.40 rJrI 40 40 40 40 20-1 r-JrA 20-1 I 1r.J 20~P'..J 20~fAl I 20 o I ~"010"'f"o I '7jZ'1 ~I ~q'J 01 ,£?l[~'"T-o ~rq3 [~r~'"'f"0 0 .j:lo t.n 3 4 5 6 3 4 S fl 3 4 S II 3 4 S II 3 4 5 6AGEAGEAGEAGEAGE FLATHORN YENTNA SUNSHINE SUNSHINE TALKEETNA CURRYSTATIONSTATiONSTATIONSTATIONSTATIONSTATION,st RUN 2 nd RUN0-1780 0-2258 n-365 0-972 0"453 0"212 rJ MALES o FEMALES Figure 22.Age composition of fish\'lheel intercepted sockeye salmon weighted hy CPlJE at selected locations on the Susitna River.1984. 3.2.2.1.2 Spawning Areas In the lower Susitna River above the Yentna River confluence,sockeye salmon did not spawn in the mainstem or associated sloughs or in any stream mouths in 1984 (Appendix 1). 3.2.2.2 Middle Reach 3.2.2.2.1 Main Channel Escapements Middle-reach sockeye escapements to Talkeetna and Curry stations in 1984 were approximately 13,100 fish and 3,600 fish respectively (Table 18). However,not all of these fish remained in the middle reach to spawn. About 83 percent of the escapement to Talkeetna Station were milling fish that spawned in the lower Susitna reach.At Curry Station,35 percent of the escapement were milling fish. In 1984,second-run sockeye were abundant in the Susitna River mainstem for three to five weeks,based on fi shwheel catches at Talkeetna and Curry stations (Figure 23).At Talkeetna Station,migration began July 22,reached a midpoint July 28,and ceased August 12.At Curry Station, the migration period was 13 days longer,beginning July 22,reaching a midpoint August 1,and ending August 25. Migrational rates of tagged sockeye salmon recovered in the lower and middle reaches are summarized in Figure 20.The data indicated that these fish migrated much more slowly in the lower reach.The slower rate of travel may have been associated with milling at the mouths of the Yentna,Talkeetna and Chulitna rivers.In the middle reach,there are no such glacial tributaries. An inseason catch reduction occurred at Talkeetna and Curry stations that may have been related to a flow change in the Susitna River.At Talkeetna Station between July 26 and 27,sockeye salmon catches dropped from a high of 1.2 fish per fishwheel hour (CPUE)to 0.2 CPUE and then climbed again to 0.9 CPUE on July 28 (Figure 23).This coincided with a high water event when mainstem discharge measurements at Gold Creek increased from 22,800 cfs on July 25 to 34,200 cfs on July 27 and then declined and remained stable around 24,000 cfs for the next two weeks (USGS provisional data 1984)(Figure 8).The fishwheel catches also changed at Curry Station at about the same time,but less dramatically. On July 26,the CPUE was 0.6;for the next two days catches dropped 50 percent to 0.3 CPUE,and then rose again to 0.6 CPUE on July 29 as high flows subsided (Appendix Table 3-17). The migrational rates of second-run sockeye salmon between Sunshine, Talkeetna and Curry stations were determined from tag recaptures (Figure 20).Migrational speeds between Sunshine and Talkeetna stations were about 50 percent slower than between Talkeetna and Curry stations (8.5 mpd).The slower rates may have been related to milling at the conflu- ence of the Talkeetna,Chulitna and Susitna rivers. A representative age,length and sex composition sample was collected from second-run sockeye salmon intercepted by fishwheels at Talkeetna 46 - - - - ~I - - - - a.5 213 ~ o 40 J E J U 60 1013 5 SEPAUG -----_. / / I I I \j,., \ \ \ JULY 13 JUNE I TALKEETNA STATION EOSl 80nk West 80nk -------- Smoothed by o·?b +c 4 Cumulolive %- - - 2 Ql 1.5 Ql -C :3: ........ t..

Four-year-01ds represented 73 percent and five-year-01ds 22 percent of -the escapement population.About 82 percent of the four-and five-year- old fish reaching Curry Station had smolted in their second year. Three-and six-year-01d sockeye salmon represented less than five percent of the escapement populations to Talkeetna and Curry stations. The average length of second-run sockeye salmon at Talkeetna Station was 513 rom and at Curry Station 495 rom (Appendix Figures 5-9 and 5-10). Generally among all age classes sampled at Talkeetna Station~males averaged about 20 mm longer than the females (Table 14).At Curry Station ~the males averaged about 40 rnm shorter.Sex composi ti on data indicated that males were less numerous at Talkeetna Station than females (0.7:1)but more numerous than females at Curry Station (1.4:1) (Table 16). 3.2.2.2.2 Spawning Areas In the middle reach,sockeye salmon spawned in the mainstem and several associated sloughs.Seven mainstem spawning sites were identified,all of which were in an area upstream of Curry Station between RM 131.0 and 141.6 (Figure 24).Individual maps of these locations are in Appendix 6.Four of the seven mainstem areas were in Side Channel 11 (RM 134.5 to 135.3)which ;s immediately below Slough 11,the major sockeye spawning area in the middle reach.All spawning observed in the mainstem was in the last two weeks of September but peak spawning was probably in mid-September (Figure 24). About 100 sockeye salmon spawned in the middle-reach mainstem in 1984. This estimate is based on the assumption that the single highest fish count (33)of all mainstem spawning areas represented about one-third of the spawning population.At sloughs,a peak count represents about one-half of the spawners (Barrett et a1.1984).A peak count was not confirmed for the mainstem spawning areas due to high flow and turbidity.Therefore it was assumed that the single highest fish count was less than one-half of the spawning population and probaby near the one-third level. Two streams in the middle reach had sockeye salmon present in 1984 (Appendix Table 6-2).These were Indian River and Portage Creek. Respective peak counts were 1 and 12 fish.Spawning was only observed in Portage Creek at its c~nf1uence with the Susitna River.The sighting was limited to a pair of sockeye occupying a redd on September 2. A total of 25 sockeye salmon occupied middle-reach stream habitats, assuming that the peak count (13 fish)represented about one-half of the population (Barrett et al.1984).This estimate ;s probably 1iberal because some of the fish may have been milling and there was only one observation of spawning. Eighteen sloughs in the middle reach were occupied by sockeye (Table 21).Thirteen of those were spawning areas.The three major spawning sloughs,in order of importance,were:11,8A and 21 (Figure 25). 48 ., I 145 Spawning Map Identification Location .Highest Observation Number River Mile Bank Fish Count Dates 1 134.6 l 2 9/29/84 2 135.0 R 8 9/29/84 3 135.1 R 2 9/15/84 4 135.2 R 5 9/15/84 5 138.7 L 4 9/15/84 6 139.0 l 3 9/8-22/84 7 141.6 R 9 9/15/84 Figure 24.Sockeye salmon spawning areas in the Susitna River mainstem middle reach,1984.

From a combined estimate of.2,325 sockeye that spawned in middle-reach streams (1%),slough (95%)and mainstem (4%)habitats,it was determined that most (82%)of the 1984 sockeye escapement to Talkeetna Station were mill i"g fish,and that most (65%)of the sockeye that reached Curry Station were middle-reach spawners.There was more milling at Talkeetna Station than at Cur~1 Station among other salmon species also (Section 4.0). In 1984,the mean average observed residence of sockeye salmon in Sloughs 8A and 11 was 8.4 days (Figure 27).Considerable differences existed in the observed-residence periods of individual fish at both sloughs,evident from the large standard deviations of the means.The main cause was probably milling.Approximately 42 percent of the 131 fish monitored at the two sloughs did not initiate spawning (Table 23). 50 - - 1 J 1 J 1 J J J ]J j 1 j J 1 Table 22.Estimated sockeye salmon slough escapements to the middle reach sloughs.1984.

Sockeye seemed to prefer to spawn in the upper areas of sloughs •.The highest concentration of observed-residence monitored fish spawned at the head of Sloughs 8A and 11.By comparison,chum salmon preferred the lower areas (Section 3.4). ~tost of the sockeye enteri n9 mi ddl e-ri ver sloughs in 1984 spent several weeks ripening in the Susitna River main channel.Fish monitored at Sloughs 8A and 11 for observed residence averaged 36 days from release at Curry Station to slough entrance (Figure 28).The distances from Curry to Sloughs 8A and 11 are 5.1 and 15.3 miles respectively.Since sockeye migrated at an average speed of 7 mpd between Flathorn and Curry stations,they could easily have traveled from Curry to the sloughs in two days (Figure 20). There are several possible advantages to ripening in the mainstem rather than in an associated slough.For example,the middle-reach sloughs are relatively small and shallow and non-turbid,making predation a greater factor than in the main channel.Also,sloughs serve as a spawning area for more than one species.Consequently,crowding and associated disease problems would be more prevalent in sloughs than in the main channel.In drainages where there is a lake associated with a spawning stream or slough,sockeye commonly ripen in the lake before initiating spawning.For example,in the Kasilof River drainage,sockeye spend three to four weeks ripening in Tustumena Lake rather than in inlet spawning streams and sloughs,which are characteristically similar to middle-reach Susitna River sloughs (Barrett 1972).Similar to the Susitna River main channel,Tustumena Lake provides good escape cover and dispersion area for tens of thousands of adult salmon. Female sockeye salmon were examined for egg retention at Sloughs SA,11 and 21 (Table 24).Most (88%)had spawned completely (Figure 29).The average egg retention for the three sloughs was 64 eggs,the median was o eggs.

The Yentna River and Sunshine Station escapements comprised about 38 percent of the Flathorn Station estimate (Figure 30).The spay-tning population below Sunshine Station,excluding the Yentna River,comprised the remaining 62 percent.Based on previous Susitna River escapement monitoring and tag recovery surveys,an unknown number of pink salmon migrating to Flathorn Station were milling fish that spawned downstream (ADF&G 1983). The migrational timings of the pink salmon escapements to Flathorn, Yentna and Sunshine stations were calculated from fishwheel catches (Figures 31 and 32 and Appendix 3).At Flathorn Station,pinks were abundant from July 21 to August 7.The migration reached a midpoint on July 28 in both the east and west channels (Appendix Table 3-3). Overall,there was 1 ittle difference in the pinks migration timing between east and west channels.Upriver at Sunshine Station,pink 56 - - - - Table 25.Es timated pi nk sa Tmon escapements to Flathorn,Sunshi ne, Talkeetna and Curry stations,by the Petersen method,with assocfated confidence intervals,1984.

At Flathorn Station,the river is comprised of two channels formed by a large island complex.Fishwheels were located on the east and west mainland banks and on the east and west banks of the largest island (Appendix Figure 2-1).Fishwheel catches of pink salmon were distri- buted among the four fi shwheel s as follows:48 percent 1eft east channel (island fishwheel),28 percent right east channel,17 percent right west channel (island fishwheel)and 7 percent left west channel. Most (76%)of the pinks migrated in the east channel (Figure 33).In the Yentna River at Yentna Station,migrating pinks favored the south bank.The south fishwheel intercepted 64 percent of the catch and the north fishwheel 36 percent.Most (64%)of the 93,919 pink salmon intercepted at Sunshine Stcttion were captured in the east bank fishwheels. Pink salmon tagged at Flathorn Station were recaptured at Yentna, Sunshine,TaHeetna and Curry stations (Figure 33 and Table 26).Tag recovery information indicated that pinks destined for the Yentna River passed Flathorn Station in numbers divided evenly between the east and west channels.Pinks reaching Sunshine Station and above preferred the east channel.About 87 percent of the recaptured Flathorn pinks were originally caught in east channel fishwheels at that station. Recoveries of tagged pink salmon were used to determine migration rates between stations in 1984.These data are presented in Appendix 3 and 59 .J:~_-SUSI rNA Figure 33.Migra~ional preference of pink salmon to the east and west channels at Flathorn Station,1984.

Males at Flathorn Station averaged 450 mm in length,15 I11TI longer than females.Combined average lengths of males and females at Yentna and Sunshine stations were 445 ~n and 441 mm respectively (Appendix Figures 5-12 and 5-13).Ma 1es averaged 15 and 16 mm longer than females at these stations.Males were more common than females at Flathorn (1.3:1),Yentna (1.2:1)and Sunshine (1.1:1)stations (Table 27). o '0~ CODE PINK median doys/ /mpd Talkeetna Station CRt.!103) Sunshine Station CRt.!80) Curry Slation CRM 120) 11/8.9 10/8.\ 6/9.7 I 4/10.0 IE lTRM 04) .2/5.Flathorn Stall on !

Pinks were observed in 12 of 17 stream-mouths between RM 28 and 98.6 (Appendix 1).Between 4,500 to 9,000 spawned in 10 of the stream mouths,mainly Willow,Birch and Sunshine creeks.The spawning period was from July 28 to September 25 with a peak during the first two weeks of August. 3.3.2 Middle Reach 3.3.2.1 Main Channel Escapements The Petersen tag and recapture method was used to determine the 1984 pink salmon escapements to Talkeetna and Curry stations.By this method,the pink salmon escapement to Talkeetna Station was 177,900 fish with a 95 percent confidence interval of approximately 171,800 to 184,400 fish.The escapement to Curry Station was 116,900 pink salmon with a 95 percent confidence interval of approximately 109,200 to 125,700 fish (Table 25). Based on the estimated number of pink salmon spawning in stream and slough habitats above Talkeetna Station,85 and 80 percent of the respective escapements to Talkeetna and Curry stations were milling fish (Section 3.3.2.2). Pink salmon fishwheel catches were used to evaluate migrational timing at Talkeetna and Curry stations (Figure 35 and Appendix 3).Pinks were abundant at Talkeetna Stati on from July 25 through August 10.The migration reached a median on August 3.At Curry Station,pinks were abundant from July 29 to August 13.The midpoint of the migration was August 4.Peak fishwheel catches occurred on August 3 at Tal keetna Station and on August 5 at Curry Station. Fi shwheel catches at Tal keetna and Curry stations i ndi cated that the escapements to those stations migrated primarily along the west bank (Figure 35).A total of 29,236 pink salmon were intercepted by Talkeetna Station fishwheels;75 percent were captured in west bank fishwheels (Appendix Tables 3-12 and 3-13).At Curry Station,the total pink salmon fishwheel catch was 17 ,394 with 70 percent of these fish intercepted by the west bank fishwheel (Appendix Tables 3-15 and 3-16). The migrational rates of tagged pink salmon recaptured in the lower and middle Susitna River r~~ches are presented in Appendix 3 and Figure 34. Based on median numbers of days between captures,pinks traveled at a rate of 7.7 mpd between Sunshine and Talkeetna stations,at 10.0 mpd between Sunshine and Curry stations,and at 17.0 mpd between Talkeetna and Curry stations.Slower travel speeds between Sunshine and the two middle-river stations were probably due to milling in the confluence areas of the Susitna,Talkeetna and Chulitna rivers. 63 - TALKEETNA STATION East Bank ----- West Bank -------- Smoothed by 0+2b-+c 4 Cumulative % - - - 20 ..... o 40 J E J U Gl e0 > 100 80 s SEPAUG /---- / rvtItJ/'I,\ I I ~I :, , I , :,I,, , , I :/I,, , / :\,\,\ :;'",\,\,\ " JULY II27I' JUNE 10 50 e0 ~ ~ -C.4a 3 .........

Pink salmon occupied 17 of the 37 sloughs surveyed in 1984 (Appendix Table 6-3 and Table 28).They spawned in only 10 sloughs:38,3A,5, Bushrod,98,AI,8A,11,20 and 21.The most important (accounting for 63%)were 8A,11 and 20 (Figure 36). Pink salmon spawned in slough habitats from the second week of August to the first week of September in 1984.Peak spawning occurred during the second and third weeks of August.

Pinks spawned in the streams during the first three weeks of August in 1984,based on surveys at Fourth of July Creek,Indian River and Portage Creek (Appendix 6).The spawning peak was between the second and third weeks of August. An estimated 29,300 pink salmon spawned in middle-rive -stream,slough and mainstem habitats.This estimate was reached by assuming: 1.stream escapements were equal to peak survey counts expanded by a factor of 1.2 (Cousens et ale 1982); 2.he 1 i copter survey counts represented about 48 percent of the fish present in Indian River (Figure 37); 68 - - - - - - - 3.at least 90 percent of the pink salmon spawned in Indian River,Portage Creek or the index reaches of surveyed streams. Therefore,in 1984,about 84 percent of the Talkeetna Station escapement were milling fish.At Curry Station,milling fish were an estimated 78 percent of the escapement. 11000 INDIAN 7000 0w....z ~60000 0 Z 0 2 5000 ~ c{ en :.::z 4000 ~ lJJ ~ ..J 3000 LL 0 a: lJJ 2000 CD ~ ~ Z 1000 - RIVER Ground survey of the first T RM.

Minimal chum spawning occured below Flathorn Station.The known spawn- ing area is Alexander Creek where the highest escapement was approxi- mately 500 fish in 1963 (ADF&G 1983).With such minimal spawning,the chum escapement estimate to Flathorn Station can be considered an estimate of the entire Susitna River escapement for that species. - - - Table 31.Estimated chum salmon escapements to Flathorn,Sunshine, Tal keetna and Curry stations,by the Petersen method, with associated confidence intervals,1984.- Population Estimate Location Parameter 1 Flathorn Sunshine Talkeetna Curry Station Station Station Station m 7,299 55,162 11 ,332 3,132 c 75,268 35,057 18,430 13,877 r 676 2,528 2,126 882 1\ N 812,694 764,958 98,236 49,278 95%C.1.755,963-737,273-94,459-46,319- 878,631 794,803 102,327 52,639 1 m =Number of fish marked. c =Total number of fish examined for marks during sampling census. r =Total number of marked fish observed during sampling census. 1\ N =Population estimate. 1\ C.I.=Confidence Interval around N. 70 - - - Figure 38 illustrates the distribution of the Susitna River chum escape- ment in 1984.About 97 percent of the total escapement was to the Yentna River and Sunshine Station.The Yentna River population was three percent and for Sunshine,94 percent.About three percent of the escapement was destined to spawn in the lower-reach mainstem and associ- ated tributaries below Sunshine Station excluding the Yentna. In 1984 the fishwheels at Flathorn,Yentna and Sunshine stations caught 7,519,1,431 and 56,681 chum respectively or about one percent,five percent and seven percent of the estimated escapements to those stations lTable 6).These fishwheel catches provided the basis for determining escapement timing (Figures 39 and 40).At Flathorn Station, chum salmon were abundant in the mainstem for 41 days.The migration began in the east channel at Flathorn Station on July 18,reached a midpoint on July 25 and ended on August 25.At Yentna Station,the chum salmon migration lasted 42 days.The onset was July 18,the midpoint was August 1 and the end was August 29.At Sunshine Station,58 miles above Flathorn Station,the migration lasted 27 days,beginning July 23, with a midpoint August 4,and ending August 19.

Chum salmon migrations in the lower reach were influenced at least twice in the 1984 season by high discharges.For example,the highest mainstem discharges from mid-July to mid-August in the Yentna and Susitna rivers occured on July 27 and 28 (USGS,provisional data).On those dates,there was a sharp drop in catches in the fi shwheel s at Flathorn,Yentna and Sunshine stations (Appendix 3).A second migrational response to discharge probably occured toward the end of the chum salmon migration.Discharges on August 20 and 21,were between 133,000 cfs and 146,000 cfs at Susitna Station (Figure 42).This coincided with a major reduction in chum salmon fishwheel catches at Flathorn and Sunshine stations. - Catch differences between opposite river-banks fishwheels at a sampling station can indicate fish migrational patterns (Appendix 3).In 1984, 83 percent of the chum salmon escapement that reached Flathorn Station migrated in the east channel.Seventeen percent of the chum escapements to Flathorn passed in the west channel (Figure 43).In the Yentna River,57 percent of the chum passed Yentna Station along the south bank.At Sunshine Station,the east bank wheels caught 92 percent of the station's chum and the west bank wheels caught the remaining eight percent. - j , !,i'\1\)I~\~:\IJVv\,.,\I)I (\II \{V \ \! \ .I J \\/I ;I~f •,.I \(J"I.:! .:\,.Ii \.' \ r\I \/ V \ /\"-.,", IV ::~"':;SUSITNA RIVER ..·...u (RM 28)..,..".-'.............. ....n .l!UJl ";:IDm _1."4" 2.IlII'm ~11!aD' e:t 1l(lllD ~I~.l %10l1Ul ~Y.<Dl·0::.....

Chum salmon occupied 10 stream mouths in the lower reach study area. Five of those were spawning areas.Spawning occurred from mid-August to the end of September.The peak occured in the last week of August and the first week of September.Total numbers of spawners were between 100 and 225 chum;most of those spawned at the mouth of Caswell Creek.

Chum salmon catches in fishwhee1s at Talkeetna Station totaled 12,749 fi sh and at Curry Station 4,228 (Tab1 e 6),whi ch represented 13 and 9 percent of the respective intercepted escapements to those stations. Based on catch timing,chum migration in the middle reach lasted for five to six weeks (Figure 45).At Talkeetna Station,chum migration began on July 25,reached a midpoint on August 5 and ended on August 15. At Curry Station,the respective dates were July 28,August 5 and August 21. Chum salmon migrated faster (or milled less)in the middle reach than in the lower reach.For example,the median travel speed of tagged fish between Flathorn and Sunshine stations was 4.5 mpd,between Sunshine and Talkeetna stations 5.4 mpd,and between Talkeetna and Curry stations 8.5 mpd (Figure 41).Slower migration rates in the lower reach may have been due to fish milling at the confluences of glacial tributaries (the Yentna,Talkeetna and Chulitna rivers). In the vicinity of Talkeetna Station,chum migration was about equally distributed,with the east and west bank fishwheels taking 46 and 54 percent respectively of the catch.In the vicinity of Curry Station, most chum migrated along the east bank (75%),on the same side of the river as most major spawning sloughs. Chum migration in the middle reach generally followed a bell-curve distribution,based on fishwheel catches at Talkeetna and Curry stations (Figure 45).The exception in the second week of August was probably related to a high discharge (Figure 8).Fishwheel catches at both stations indicated that chum migration slowed when mainstem discharge increased and accelerated after peak discharge.Previous studies also indicated that chum salmon responded to rapid increases in mainstem discharge by slowing migrational travel (ADF&G 1981,1982). Representative age,length and sex samples were collected from mid- dle-river chum salmon at Talkeetna and Curry stations in 1984.Escape- ments to both stations were comprised of three-to six-year-old fish (Table 34 and Figure 44).About 70 percent were four-year-olds.All 81 ~--~~----------------,-----'-~,:..--------------------'-- ... 10 ",..-----100 TALKEETNA STATION IEastBank 8 West Bank ---------/60 l3)Smoothed by a+2bic l3)4 ~-,.£.Cumulative Ofo - - -Q)3 6 60 >"L ...J 0 IIIII!f!0 :I:'4 '40 J"E.£.J(I)U -I..L.2 20 "0 13 27 •S JUNE JULY AUG SEP IlI!!l! 15 /,.----100 CURRY STATION IEastBank 80 l3)West Bank---------I ~l3)Smoothed by Q+2b+c .£.10 4 /Q)3 "Cumulotille "10 - - - 60 > L .->J 00 ~ I 413 J"E.£5 J(f)U I..L.20 -, 13 13 I'27 II 25 a s JUNE JULY AUG SEP Fi gure 45.~1ean hourly and cumulative percent fishwheel catch of chum salmon by two day periods at Talkeetna and Curry stations,-1984. - - 82 - .- - had migrated to sea as juveniles in their first year of life.The average chum length at Talkeetna and Curry stations was 600 mm (Table 34).Males averaged 12 mm longer than females (Table 34).The male-to-female ratio was slightly less as Talkeetna (1.4.1)than at Curry (2.0.1). 3.4.2.2 Spawning ,Areas In 1984,36 mainstem chum spawning areas were indentified in the middle reach,nine downstream of Curry Station and 27 upstream.Spawning was observed from September 1 to September 29 (Appendix Table 6-1).Peak spawning probably occured in the first two weeks of September,based on peak live fish counts.However,spawning may have peaked as much as a week earl ier.Turbid mainstem conditions through the month of August resulted in poor survey visibility,and may have prevented documentation of earlier spawning,if it did occur. The highest single count of live chunl salmon in the 36 mainstem spawning areas was 1,266 fish (Figure 46).Assuming this count represented about a third of the total population,approximately 3,800 fish spawned in the middle mainstem Susitna River reach.The reason for expanding the peak count by a factor of 3.0 is based on information which indicates that a peak live and dead count of chum salmon represents about 50 percent of an actual escapements under ideal survey conditions (Cousens et al. 1982).Considering that there were poor mainstem survey conditions in late August near the peak of spawning,and that dead fish were not counted due to the uncertainty of their origin,an expansion factor of 3.0 the authors considered reasonable. In 1984,11 streams were occupied by chum salmon in the middle river reach (Appendix Table 6-2).Peak counts of those streams totaled 3,814 fish (Table 36).Most (98%)of the fish were in Indian River,Portage Creek and Fourth of July Creek (Figure 47).Spawning in those streams occurred from about the last week of July through the fi rst week in October with the peak in the second and third weeks of August (Appendix Table 6-2). The spawning areas and upper migration limits for the 11 chum-occupied streams used are illustrated in Appendix 6.Most of the mouths of those creeks were spawning areas.In Indian River,chum salmon spawned in the fi rst ni ne mi'1es,with major,spawni ng in the fi rst two mil es.At Portage Creek,spawni ng extended about 7.5 mi 1es ups tream to Thorofa re Creek (TRM 7.5).Spawning was discontinuous in that reach.Chum enter- ing Fourth of July Creek spawned from the mouth to a point about 1.5 miles upstream.The majority of spawning was at the mouth. The general importance of the chum spawning habitat in this reach, including the mouths of Indian River and Portage Creek,was determined by comparing escapement counts within subreaches (Appendix Table 6-2). As illustrated in Figures 48 and 49,relatively high counts of live chum were recorded (by ground and helicopter surveys)in the index reaches of those streams throughout the entire spawning period.About 45 percent of the peak count of Indian River was in the first mile,and 21 percent of the peak count of Portage Creek was logged in the first one-quarter mil e. 83____..._~_T ;a'S'!II_.__,..........---'---.............._-------------------- :Talk ••tna (RM 103) (NOT TO SCALE) - ...... - 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 .re:u$.'JJ:l2.qc()..f~ Location SpawnTng L t'Spawning Map id Highest Obsel"'vation Map Id oca 10n Highest Obsel"'vation Nl.JIlbel'"RH {;./JJTA Bank Fi sh Count Oates Numbel'"RM Bank Fi sh Count Dates "R($-0.fi7r rc 6- 100.9 iOo;"f~R ,.,89 9/15-29/84 19 131.1 13j..3 L7 81 9/1-8/84 110.1 /lO·ljt.·L"3 4 9/1-8/84 20 131.3 i~i.7LL If 57 9/8-29/84 114.0 W.,·It\C;46 9/15/84 21 131.5 !"3/;1 L l J./.102 9/8-24/84 114.6(i!:>,DItR "3 69 9/1-22184 22 131.7 1-:>i.7L-L if 20 9/6-22/64 11S.0)1l,·oR R 3 15 9/1-29/64 23 131.8 I'3L'iij,l 2-18 9/15/84 115.1 115.Ic'~R 2.50 9/8/84 24 134.613Q.iR:rz..1f 2 9/29/64 118.9 1l'l5,'11l-L "21 9/1-15/84 25 135.1 1}<f,1I<R If 8 9/15/84 119.1 lI~.ILL 10 15 9/1-15/84 26 135.2 $4·~R.R If 40 9/15/84 119.4h~·"L"4 2 9/8/84 27 136.1n~'H~Rf.o 131 9/1-8/84 120.9 lJ.1.IL.L 7 5+l"'edds 10/13/84 26 136.3 I'3FH~R {,;31 9/8/64 121.6 1~I·U.R II 2 9/15/84 29 136.8 1%·;~R ~6 9/15/64 124.0 11<1.jJ...L q.18 9/22184 30 138.7 l'it·1L.l 10 36 9/8-15/64 124.9 l:I.lI·<J>Rc 6 6 9/8-29/64 31 139.0 \''1.0\\..l?87 9/1 -22184 128.3 1l6'7~R <7 73 9/8-15/84 32 140.5 ll/o·I1RR I.f 6 9/15/64 128.6 )J.'i.?~~77 9/1-29/64 33 140.6 ['-lo.~~<0 2 9/15/64 129.8 130'~R '3 18 9/1-15/84 34 141.4Iltl,'R..R (P 45 9/1/84 130.0 i l R 3 5 9/8/84 35 141.6 \4\,'!RR q 1 9/15/84 130.5 I,R3 36 9/1-15/84 36 143.31HOLl <;45 9/l/64 Figure 46.Chum salmon spawning areas in Susitna River mainstem middle reach.1984.

Chum salmon monitored for observed residence at sloughs AI,SA and 11 averaged from 14 to 20 days in the Susitna River mainstem between the time they were ta9ged and the time they entered one of those study sloughs (Figure 51).The mean average time was 19 days.The majority of that time was probably spent ripening in the Susitna River mainstem. Chum salmon averaged 8.5 mpd travel between Talkeetna and Curry stations (Figure 41).The furthest study slough (Slough 11)is 15 miles upstream from Curry,or about two days if migration were direct.Further evidences that the mainstem was used as a ripening area were 1)the several-week period between peak fishwheel catches at Talkeetna and Curry stations;2)dates of peak live counts at sloughs 8A,11 and 21 (Figure 50 and Appendix Table 6-3);and 3)fish spawning in areas downstream from their tagging sites,.indicating that not all chum migrated directly to spawning areas.Mill ing upstream of a spawning area is probably more frequently an artifact of fish using the mainstem for ripening than a by-product of seeking out a new spawning habitat or not initially recognizing a natal area. 88 - - _. 1 J •1 j j 1 1 )1 j ]]j 1 ,-------~ 60.,SLOUGH A'60, ~O n-7 .-14.1 daysII SO,4.6 days >- ~o ~ !i 40 W :l 0 >- w !i 40 ~30 W :l ~ 0 z w w e:30 u Cl:lO ~S1.2 ...

Chum salmon had a mean average observed residence at sloughs AI,8A and 11 of 6.8 days (Figure 52).The lowest average was at Slough 11 (6.1 days)and the highest at Slough 8A (7.9 days).These estimates do not represent the spawning life of chum salmon in the sloughs because not all monitored fish initiated spawning. Some chum salmon whi~h entered sloughs AI,8A,and 11 spawned elsewhere. At least three of the 131 fish monitored at those sloughs entered more than one slough.For example,one chum entered Slough BA,remained there for about a week and four days later entered Slough 11,where it finally spawned.About 18 percent of the chum monitored for observed residence were located only once in the three study sloughs.Those fish probably entered the study sloughs for milling or ripening purposes only.An unknown percentage of fish may have been removed by bears. The zonal distribution of spawning in sloughs 8A and 11 is outlined in Table 38.The lower reaches were used more by chum than the upper reaches,based on observed residence data.In contrast,sockeye spawned mare frequently in the upper reaches. l!I'I'\'AI - - - Table 38.Percentages of chum salmon monitored for residence life that initiated spawning by habitat zone at sloughs A',8A,and 11.1984, - 345 Spawning Location3 by Habitat ZoneSlough' n2 Percent with RM Spawning Al 7 85.7 RM 124.6 8A 30 83.3 RM 125.1 "94 74.7 RM 135.3 RM =River Mile 3.3 2.1 2 33.3 46.7 16.0 16.0 23.4 4.3 6 11.7 7 1.1 Percent Not Spawning 4 14.3 16.7 25.3 2 Total sample for sloughs A',8A and 11 equals 131 fish;128 individual fish were act;'41ly monitored as three individuals spent time in both sloughs. 3 Habitat zones defined in Appendix Figures 6-4 and 6-5. 4 Includes milling fish and bear killed and other pre-spawning mortalities.

The coho salmon escapement into the Susitna River drainage was defined as the estimated escapement to F1athorn Station.Below F1athorn Station,only Fish and Alexander creeks drainages are known to support coho spawning populations (ADF&G 1982).Historically,the highest counts were 380 fish in Red Shirt Creek (1952)(Fish Creek drainage)and 2,000 fish in Alexander Creek (1964)(ADF&G 1982). The geographic distribution of coho salmon in the lower reach above Flathorn Station,based on 1984 escapement monitoring at Flathorn, Yentna and Sunshine stations,is illustrated in Figure 54.As shown, the combined escapements to Yentna and Sunshine stations accounted for about 60 percent of the escapement to Flathorn Station.The remaining 40 percent spawned in the lower river below Sunshine Station excluding the Yentna River.

At Yentna Station.the coho migration was from July 21 to August 22. with a midpoint on August 3 (Figure 55).At Sunshine Station,coho salmon were abundant from July 29 to August 29.The migration midpoint was on August 11 (Figure 56). Migratory distributions at Flathorn.Yentna Jnd Sunshine stations were based on fishwheel catches (Table 6 and Appendix 3).At Flathorn Station 9 individual fishwheel catches were as follows:18 percent right east channel.38 percent left east channel.35 percent right west channel and 10 percent left west channel.The majority of the coho (55 percent)migrated in the east channel (Figure 57).The data also indicated a strong preference for coho to migrate midriver at that site. The two midriver fishwheels intercepted a combined 72 percent of the total catch.At Yentna Station coho migrated primarily (81 percent) along the south bank.At Sunshine Station.58 percent of the coho migrated along the east bank and 42 percent along the west bank. Coho salmon migrating past Flathorn Station enroute to Yentna Station migrated primarily (67%)in the east channel (Table 43).Coho salmon reaching Sunshine Stati()n and above also passed Flathorn Station pre- dominately (90 percent)in the east channel. .... - 96 ..... o 4121 J E J U 1121121 Bra 213 20 Q) 61a > ..... o ~9 J E J U Q) 60 > B9 11219 s SEP s SEP Z2 AUG AUG a --".---- I II II',\..:\ty , I I I I V~I , I l \/1 \•:'," :/V' :'/ !/ j/ JULY JULY 27 27 IS JUNE IS JUNE YENTNA STATION North Bonk ---- South Bank --------- Smoothed by o+2b+c 4 Cumulative 0/._ Cumulative %--- FlATHORN STATION East Chonnel---- West Channel------- Smoothed by a +2b +c 4 1.5 Q,I Q,I...c :3 "-L Jo:c "-...c lJI i.J..0.5 2.5 2.5 2 2 QI QI...c :3........t.5 L Jo:c ..........c lJI I.L.0.5 Figure 55.Mean hourly and cumulative percent fishwheel catch of coho sa lmon by two day periods at Fl athorn and Yentna stations. 1984 .. ..- 97 8 SUNSHINE STATION Eost Bonk --------- Wul Bonk -------- Smoolhed by 0 +2 b ~c 4 Cumulohve '"10 - - - 100 8a ~ Gea> .... 0 ..a Je Ju 20 e AUG SEPJULY"JUNE Figure 56.Mean hourly and cumulative percent fishwheel catch of coho salmon by two day periods at Sunshine Station,1984. ..c:--SUSITNA - Figure 57.Migrational preference of coho salmon to the east and west channels at Flathorn Station L 1984. 98 ..- Table 43.Comparison of numbers of coho salmon tagged by east and west channel fishwheel s at RM 22 to the number of tag numbered recaptures by bank at Yentna Stati on and at RM 80,103 and 120 combined,1984. Migrational rates between Flathorn and Yentna stations and Flathorn and Sunshine stations,based on median days traveled,were 1.0 mpd and 2.3 mpd,respectively (Figure 58").The slower travel.rate between Fl athorn and Yentna stations was probably due to milling activity in the vicinity of the Susitna and Yentna rivers confluence. Age,length and sex composition information was collected from the escapements reaching Fl athorn,Yentna and Sunshi ne stations in 1984. Four-year-old fish represented 64,70 and 64 percent respectively of the escapements (Table 44 and Figure 59).Three-year-old fish were the second most abundant at all three sites.Of the coho salmon returning to Flathorn,Yentna and Sunshine stations,64,70 and 64 percent respec- tively had migrated to the ocean in their third year of life.The res pect i ve mean 1engths of the cohos sampled at Fl athorn,Yentna and Sunshine stations were,542 mm,557 mm and 546 mm (Appendix Figures 5-21 to 5-23).The slightly longer average length recorded at Ventna Station was due to a higher percentage of four-year-old fish returning there than to the other two stations (Table 45).At Flathorn and Yentna, males were generally longer than females.At Sunshine Station,the male and female average lengths were the same.Generally,males were more abundant than females at Flathorn and Sunshine stations and fewer in number at Yentna Station (Table 46). Coho salmon fecundities were determined from 22 samples collected at Sunshine Station in 1984.All samples were collected on August 22.The average fecundity was 2,964 eggs per female,ranging from 1,394 to 3,984 eggs (Table 47).The fecundity samples were collected prior to the full egg maturation and they became fragile and difficult to count after freezi ng and thawi ng.Those di ffi culti es introduced an unknown error component in the analysis. 99 ------~--- Table 44.Age composition by percent of the coho salmon escapements to Fl athorn,Yentna, Sunshine,Tal keetna and Curry stations based on catch samples weighted by fishwheel .

Susitna River coho fecundities may be greater than other Alaskan and Canadian stocks.Hart (1973)reported the mean fecundity of 550 mm coho salmon at 2,500 eggs.Based on reg'ression analysis,the estimated fecundity of similarly sized Susitna coho would be 2,860 eggs,or 360 more than reported by Hart (Figure 60). 3.5.1.2 Spawning Areas Coho salmon spawned in two lower-river mainstem sites in 1984.An estimated 200 to 400 fish spawned at RM 87.5 and 90.3 during the last week of September and first two weeks of October (Appendix 1). In 1984,coho utilized 11 of 17 lower-river stream mouths for either passage or ho 1di ng.They were present from the fi rst week of August 'through the 1ast week of September and were most abundant the 1ast two weeks of August.Coho did not spawn in any lower-river stream mouths in 1984 (Appendix 1). Coho spawned in one lower-river slough (RM 57.0)in 1984.Approximately 10 to 20 coho spawned in the slough during the first two weeks of October (Appendix 1). 3.5.2 Middle Reach 3.5.2.1 Main Channel Escapements The 1984 coho salmon escapements to Talkeetna and Curry stations were quantified using the Petersen tag and recapture method.About 11,800 coho salmon migrated to Talkeetna Station.The approximate 95 percent confi dence i nterva 1 associ ated with thi s estimate was 10,500 to 13,600 fish.The estimated escapement at Curry Station was 2,200 fish,with an approximate 95 percent confidence interval of 1,500 to 3,700 fish (Table 42). Migrations reaching Talkeetna and Curry stJ.tions comprised six percent and one percent respectively of the Susitna River escapement as recorded at Flathorn Station (Figure 54).Based on the estimated number of coho that spawned in the middle reach (Section 3.5.2.2),about 57 percent of the Ta 1keetna Stat i on escapement and 45 percent of the Curry Station escapement were milling fish. Based on fishwheel catches,coho salmon were abundant at Talkeetna Station from July 31 to August 29 (Appendix Table 3-14).The migration reached a midpoint on August 12.At Curry Station,coho salmon were abundant from August 1 to August 28.The mi grati on medi an was August 11. Fishwheel interceptions at Ta'lkeetna and Curry stations were used to determine migrational characteristics at those sites (Figure 61).A total of 1,526 coho salmon were captured at Talkeetna Station.The west 105 4200-1 •42°°1 • 3850-1 •• ••..51 • •• •3500~3500 ••31~WJ ••~•3150 en ~C) C)<!I I •&oJ W "-"-2800 0 0 •a:a:::w WmCD ::IE 24 ::IE 245......::>::>a z z 0'1 •2100~•••••••••2100-1 ••,J Y"-2917.0 i'10.5(x)175° 1 Y=1153.4 +0.8(x) r~0.4 r2..0.5 1400J •1400 I 1 I i 525 550 575 600 1350 1800 2250 2700 3150 LENGTH (mm)WEIGHT (g) Fi gure 60.Number of eggs for coho salmon sampled at Sunshine Station on August 22,1984 as a function of length and weight. 1 .J I J ]]••..1 J I ••J ••J I TALKEETNA STATION East Bank ----- West Bonk -------- Smoothed by Q+2b~c4 .

Based on median travel days,the travel speed between Sunshi ne and Talkeetna stations was 3.3 mpd,between Sunshine and Curry stations 4.0 mpd,and between Talkeetna and Curry stations 5.7 mpd (Figure 58). Age,length and sex data were collected from coho escapements at Talkeetna and Curry stations.Based on that information,the escape- ments to both stations were primari.ly four-year-old fish,67 and 52 percent respectively (Table 44).Most of the returning escapements to Talkeetna (67%)and Curry (52%)stations had smolted in their third year of life.The average lengths recorded at Talkeetna and Curry stations were 559 and 531 ll11I (Appendix Figures 5-24 and 5-25).The shorter average coho length at Curry was due to a larger percentage of three-year-old fish at that station (Table 44).Males were slightly more abundant than females at both Talkeetna and Curry stations (1.1:1) (Tab 1e 46). 3.5.2.2 Spawning Areas Coho spawned in one middle-river mainstem site in 1984 (Appendix Figure 6-16).On August 24,two coho were observed spawning off the Susitna River west bank at RM 131.5.No other mainstem sites were identified. Coho salmon occupied three of 37 middle river sloughs surveyed in 1984. Fish observed in those three sloughs--Moose,11 and 15--were considered milling (not spawning)fish based on single sightings,no observed carcasses and no observations of spawning activity. Coho salmon occupi ed 10 of 25 streams surveyed in the mi ddl e reach (Appendix Table 6-2).The peak coho survey count of the 10 streams was 1,434 fi sh.Based on those counts,the maj ority (70%)of the coho salmon in middle reach were in Indian River,Whiskers Creek and Chase Creek (Table 48 and Figure 62). Coho salmon spawned in streams from the third week of September to the second week of October (Appendix Table 6-2).The spawning period in streams reached a peak during the last week of September. The upper limits of migration in Whiskers Creek,Chase Creek and Indian River were 0.9 miles,1.1 miles and 8.7 miles,respectively (Appendix 6).Coho salmon in Whiskers Creek sp~wned intermittently to the upper 1 imit of their migration.The stream mouth was the most important spawning area.In Chase Creek spawning occurred discontinuously to the upper mi grati on 1imit.Coho spawned throughout Indian River from the stream mouth to TRM 8.1.Two major coho spawning reaches were located from TRM 2.7 to 5.3 and from TRM 7.6 to 8.1.Major spawning was also observed ina small Indian River tributary located at approximately TR~l 8.1. 108 - - ..

The study stations and their locations were: Flathorn at RM 22,operational for the first time in 1984; Yentna at TRM 4,upstream from the mouth of the Yentna River at RM 28; Sunshine at RM 80; Talkeetna at RM 103; Curry at RM 120. The river divisions were: Lower reach from RM 0 to the Chulitna River confluence at RM 98.6; Middle reach from the Chulitna confluence to upper Devil Canyon at RM 161. The surveys referred to in the text were: 1976 through 1980,by ADF&G Sport Fish,of chinook index streams (Table 12); 1981 through 1984,by ADF&G Su Hydro and Sport Fish cooperatively, of chinook index streams; 1981 through 1982,by ADF&G Su Hydro of all species,of lower-reach main channel and of middle-reach main channel,side channels, sloughs and streams; 1983,as 1981 through 1982,but no main channel surveys; 1984,as 1981 through 1982,but both lower-and middle-reach main channel,side channels,sloughs and streams.

An estimate of the total Susitna River chinook escapement is not available.The only monitoring of chinook salmon in the lower reach was at Sunshine Station,where escapements have been quantified since 1982. Drainage-wide surveys undertaken since 1981 established most chinook escapement below Sunshine Station. 4.1 Chinook Salmon In the last 10 years chinook salmon returning to the Susitna River have not been a target species in the commerical fishery of Upper Cook Inlet because the early migration of this species precedes the annual opening date of the fishery (ADF&G 1982).However,there is a freshwater sport fishery for Susitna River chinook salmon.The annual harvest for 1981 through 1983 .averaged 7,800 fi sh (pers.comm,_K.Delaney).The sport take is princi pa lly from tributary-spawning stocks in the lower-river reach.In the Susitna River drainage,there are about 60 chinook salmon spawning populati ons (ADF&G 1982).The most important spawning areas are Alexander Creek (RM 9.8),Deshka River (RM 40.5),Lake Creek (RM 28) and Prairie Creek (RM 97.1)(Barrett et ale 1984). In the lower reach,estimated chinook escapements to Sunshine Station were 52,900 in 1982,90,100 in 1983 and 121,700 in 1984,for a three-year average of 88,200 fish (Table 49 and Figure 64). Middle-reach chinook escapements have also improved over the last three years (Figure 64).At Talkeetna Station the escapement has ranged from 10,900 to 24,800 fish and averaged 16,700 fish since 1982.At Curry Station escapement has ranged from 9,700 to 18,000 fish and averaged 13,000 fi sh.The 1984 escapements to these stati ons doubled those of 1982 and 1983. The escapement increases since 1982 may be partly due to reduced foreign fishing in the Gulf of Alaska (pers.comm,K.Middleton,Middleton and Associates). Mi 11 i ng fi sh compri sed some of the mi ddl e-reach chi nook escapements. For example,in 1984,45 and 24 percent of the respective Talkeetna and Curry stati ons escapements returned downstream to spawn in the lower reach,primarily in the Talkeetna and Chulitna river drainages.The lower percentage for Curry was typical of all years. 113 Table 49.Escapements by species and sampling locations for 1981-84.

In 1984,some chinook stocks migrating past Sunshine Station were segregated.Chulitna River spawners preferred the west bank,Talkeetna River spawners the east bank.Middle-river fish migrated in even numbers along both banks. There was indication of a similar pattern in 1983.However,in 1981 and 1982 sampling methods at Sunshine Station did not differentiate specific populations~ Chinook migration was slower during high flows.In 1984,a peak high- water discharge of 93,000 cfs (USGS)at the Parks Highway Bridge (RM 83),resulted in a sharp catch reduction in the Sunshine Station fishwheels.The same flow event coincided with similar catch reductions at Talkeetna and Curry stations.In 1981 and 1982,migration of radio- tagged fish was delayed at high flows. Chinook migrated more slowly between Sunshine and Talkeetna stations than between Taol keetna and Curry stations for the last three years (Table 50).The slower migration may be associated with milling in the confluence area of the Talkeetna and Chulitna rivers.

Figure 65.~igrational timing of chinook salmon based on fishwheel CPUE at Sunshine,Talkeetna and Curry stations in 1981-B4. J ]I I ....•I .,.•~]J J d '.J J J .- Ages of returning chinook ranged from three to seven years,with six-year-ol ds predomi nant (Tables 51 and 52).An abundance of three-year-old males partially accounted for uneven sex ratios.Lengths averaged from 602 to 816 mm.Greater mean lengths in 1984 reflected a higher proportion of older fish than in previous years. All chinook spawning occurred in streams.There was no evidence of spawning in the mainstem or associated sloughs downstream of Devil Canyon from 1981 through 1984.Stream mouths in the lower reach were used for passage only,but in the middle reach,many stream mouths were both spawning and passage areas.In 1984 there was spawning at the mouths of Whiskers Creek,Fourth of July Creek,Indian River and Portage Creek (Appendix 6).Since 1982,chinook have been documented in two Devil Canyon streams,Cheechako and Chinook creeks (Table 53.).About one percent of the middle-reach escapement have spawned in those streams for the last three seasons. In the middle reach,there has been an 87 percent annual increase in chinook stream escapements over the last four years (Table 53).Most of the increase has been in Indian River and Portage Creek.Those streams supported 95 percent of the middle-river spawning. 4.2 Sockeye Salmon The Susitna River supports two runs of sockeye salmon.The first-run is smaller,and unlike the second-run is not subject to a commerical fishery.The first-run probably is in the range of 5,000 to 10,000 fish,based on three years of escapement monitoring at Sunshine Station (Barrett et ale 1984)and an unpublished sighting of suspected first-run sockeye in Fish lake Creek.in the Yentna River drainage by Barrett in 1973.The second-run of sockeye salmon is substantially larger, comprised of over 50 separate populations.Second-run stocks are harvested by drift and set net fishennen in Upper Cook In1 et.The commercial contribution of Susitna River stocks to that fishery is in the range of 10 to 30 percent (Barrett et al.1984).Susitna River second-run sockeye escapements have not been completely quantified. However,mi nimum annual escapements of 175,900 to 272,900 second-run fi sh have been estimated for 1981 through 1983.The estimates were detennined by escapement monitoring to Yentna and Sunshine Stations (Barrett et al.1984).In 1984,the minimum drainage-wide escapement was an estimated 605,800 sockeye,based on a first-year tag-and- recapture operation at Flathorn Station (Section 3.2). 4.2.1 First-run First-run sockeye salmon esrapements to Sunshine Station were approximately 5,800 fish in 1982,3,300 fish in 1983 and 4,800 in 1984. These reflect escapements to the inlet stream of Papa Bear Lake,the only known first-run spawning area above Sunshine Station. First-run sockeye were abundant in the lower river at Sunshine Station from the first through the third weeks of June for the last three years (Figure 66).Most migrated along the east bank.First-run fish milled in the middle river as far as Talkeetna Station,but returned to the inlet stream of Papa Bear lake to spawn. 117 Table 51.Analysis of chinook salmon age data by percent from escapement samples collected at Sunshine.Talkeetna and Curry stations in 1981-84.

Middle-river sockeye escapements to Talkeetna Station ranged from 3,100 to 13,100 fish,with a four-year average of 6,300 (Figure 67).At Curry Station,the range was 1,300 to 3,600 fish with a 2,400 fish average. The 1984 escapements to these stations were the highest on record. A majority of sockeyes at Talkeetna Station were milling fish that returned downstream,spawni ng primarily in the Talkeetna and Chul itna river drainages.Of that stations escapement,milling fish comprised 54 percent in 1981,52 percent in 1982,62 percent in 1983 and 83 percent in 1984.Less milling occurred at Curry Station.Portions of the Curry escapement that later spawned downstream were 11 percent in 1981,none in 1982,16 percent in 1983 and 38 percent in 1984. Sockeye were abundant annually in the lower reach between the second week of July and the second week of August,with a peak near the fourth week of July (Figure 69).In the middle river,fish have been abundant from the thi rd week of July to the fourth week of August,wi th a peak between the last week of July and the first week of August. In 1984,the majority of the sockeye escapement destined for Yentna and Sunshine stations passed Flathorn in the east·channel.Annual migrations past Yentna and Sunshine were heaviest along the south and east banks.In the middle river at Talkeetna Station,travel was evenly ·divided between east and west banks,while at Curry Station most migration was along the east bank. Migration speeds have been generally slower in the lower reach than in the lTIiddle reach (Table 56).Slower travel speeds may be associated with milling,particularly at major river confluences. Lower-and mi ddl e-river sockeye escapements for the 1ast four years included fish ranging in age from three to seven years (Tabll 54).Most were four and five years old.Nearly all sockeye had smolted after one winter in fresh water.Fish lengths averaged between 466 and 580 mm (Table 55).Sex ratios varied considerably from year to year and station to station (Table 55). 123 ~ I fa 1981 1m 1982 ~1983 ~1984 oo o-. -oo oo..... -ooon ~ o -oon .';-. oo...

In a 1983 study,estimated sockeye fecundity was 3,350 eggs per female. Thi s represents about 350 eggs 1ess than the mean fecundi ty of North American stocks reported by Hart (1973). There was no evidence of spawning in the lower-river main channel or side channels in the last four years.In addition,stream mouths and sloughs,surveyed only in 1984,were not spawning areas. Minor spawning occurred in the middle-reach mainstem for two of the last four years.Eleven fish were observed spawning at one site in 1983,and 33 fish at seven other sites in 1984.The total numbers of mainstem spawners in 1983 and 1984 were about 35 and 100 fish respectively, assuming that about one-third of the spawners were present at the time the highest counts were recorded.Streams in the middle reach had little or no spawning activity in the last four years.Only one pair of stream-spawning sockeye was observed in 1984,at the mouth of Portage Creek. Essentially all sockeye spawning in the middle reach occurred in sloughs (Table 57).Since 1981,sloughs 11,8A and 21 have supported 90 percent of the spawning.Peak spawning in sloughs occurred around the second week of September. In 1983 and 1984,sockeye salmon were monitored at several middle-reach sloughs for observed-residence data.The average time from slough entry to mortality or departure was 11.8 days per fish in 1983 and 8.4 days per fish in 1984.Sockeye escapements to middle-reach sloughs were 126 - 1 1 ]-I 1 ]--I --)J -]]J I J j Table 57.Peak survey counts and percent distribution of second-run sockeye salmon in sloughs above RM 98.6 in 1981-84. 1981 1982 1983 1984 Percent Percent Percent Percent Average % River Peak l Distri-Peak l Distri-Peak l Distri-Peak l Distri -Distri- Slough Mile Count bution Count bution Count bution Count bution bution 1 99.6 0 0 0 0 0 0 10 1.1 0.3 2 100.2 0 0 0 0 0 0 7 0.8 0.2 3B 101.4 1 0.1 0 0 5 0.9 20 2.2 0.8 3A 101.9 7 0.5 0 0 0 0 11 1.2 0.5 5 107.6 0 0 0 0 0 0 1 0.1 *6A 112.3 1 0.1 0 0 0 0 0 0 *8 113.7 0 0 0 0 0 0 2 0.2 0.1 8C 121.9 0 0 2 0.3 0 0 0 0 0.1 86 122.2 0 0 5 0.8 0 0 1 0.1 0.2 Moose 123.5 0 0 8 1.3 22 4.0 8 0.9 1.1 8A 125.4 177 14.3 68 11.2 66 11.9 128 13.8 13.2 6 126.3 --8 1.3 2 0.3 9 1.0 0.8 9 128.3 10 0.8 5 0.8 2 0.3 6 0.6 0.7 96 129.2 81 6.5 1 0.2 0 0 7 0.8 2.7 9A 133.8 2 0.1 1 0.2 1 0.2 0 0 0.1 .....10 133.8 0 0 0 0 1 0.2 0 0 * N 11 135.3 893 72.0 456 75.2 248 44.7 564 61.0 64.8 -....J 15 137.2 0 0 0 0 0 0 1 0.1 *17 138.9 6 0.5 0 0 6 1.1 16 1.7 0.8 19 139.7 23 1.9 0 0 5 0.9 11 1.2 1.2 20 140.0 2 0.1 0 0 0 0 0 0 0.1 21 141.1 38 3.1 53 8.7 197 35.5 122 13.2 12.3 22 144.5 - - --0 0 2 0.2 0.1 TOTALS 2 1,241 100.0 .607 100.0 555 100.0 926 100.2 100.1 -- Peak count includes live plus dead fish. 2 Percent distribution totals may not equal 100 due to rounding errors. *Trace. about 2,200 fish in 1981,1,500 in 1982,1,600 in 1983 and 2,325 in 1984.The estimates were calculated using two years of observed- residence data and four years of live fish counts. In 1983 and 1984,female sockeyes were examined for egg retention at several middle-reach sloughs.The average was 249 eggs per female in 1983 and 64 eggs per female in 1984.For chum salmon,there was a positive correlation between egg retention and spawner density in sloughs in 1983 and 1984.That was not apparent in sockeye.Slough escapements were 40 percent higher in 1984 than in 1983,but egg retention was about three times lower. 4.3 Pink Salmon Susitna River pink salmon stocks annually comprise about 85 percent of the Upper Cook Inlet pink salmon commerical catch (Barrett et al.1984). They are commercially of least value and comparatively not as intensely fished as sockeye,chum and coho salmon.Returning Susitna River pink salmon stocks utilize a minimum of 40 tributaries within the drainage. Enroute to or in their natal spawning streams,pinks are subjected to a recreational sport fishery.The Susitna River even-year (1982)sport harvest of pinks was about 17,400 fish (Mills 1983).That represented 32 percent of the pi nk salmon harvest recorded for the enti re South Central region.Odd-year harvests were approximately 8,700 fish (1981) and 4,700 fish (1983)(Mills 1983,1984). Since 1981,the combined Yentna and Sunshine stations pink escapements have been estimated at 86,000 (1981),891,000 (1982),101,200 (1983)and 1,386,300 (l984)(Table 49).The 1984 pink escapement to Flathorn Station was about 3,629,900 fish,60 percent higher than the combined Yentna/Sunshine figure for that year.Combined Yentna and Sunshine escapements averaged 93,400 pinks in odd years and 1,138,400 in even years (Figure 70)~Yentna and Sunshine escapements were within 30 percent of each other except in 1984,when higher-than-average numbers of pinks were recorded at Sunshine Station. In the middle river at Talkeetna Station,odd-year pink salmon escapements averaged 5,900 fi sh,whi 1e even-year escapements averaged 125,500 (Table 49 and Figure 71).Average odd-and even-year escapements at Curry Sta:ion were 3,300 and 87,900 fish.At both stations,the 1984 escapement was about twice the previous even-year escapement. Based on spawning ground surveys in 1984,85 and 80 percent of the pink salmon reaching Talkeetna and Curry stations were mill "jng fish. The lower reach below Sunshine Station produced most of the pink salmon escapement.In 1984,10 percent of the escapement reaching Flathorn Station spawned in Yentna River tributaries,60 percent spawned in lower-reach tributaries between the Yentna River and Sunshine Station, and 30 percent spawned above Sunshine Station,mainly in Talkeetna River,Chulitna River and middle-reach tributaries.These are approxi- mate values because a portion of the escapement reaching Flathorn Station probably spawned below that site,primarily in Alexander Creek. 128 - - - - - ,~3750 3629.9 0 0 ~Combined Yen Ina (TRM 04) 0 a Sunshine (RM 80 J Stations x 3000 ~Fla1horn Station (RM 22) !~ t- Zw ~2250 ~w Q. cl 0 1500(/) w 38 6. ::::E 890.5 =>750::::E z ::::E 85.6 101.2.- 0 1984198119821983 Figure 70.19R1-84 Sus itna River oink salmon escapements based on population estimates at Fl athorn,Yentna and Sunshine stations. ::::1 I!2000 ~.. 1000 470::: ooQ 410- X 350- ~••;; o..

At F1athorn Station,most pinks migrated in the east channel in 1984. Four years of data from Yentna and Sunshine stations indicated heaviest migration along the south and east banks.In the middle river,east bank travel was predominant at both Talkeetna and Curry stations. Recovery of pink salmon tagged at Flathorn Station in 1984 indicated that Yentna River fish were evenly distributed in the east and west channels at F1athorn,whereas pinks destined for Sunshine Station migrated mainly in the east channel. Pinks traveled at a slower rate between Flathorn and Yentna stations than between F1athorn and Sunshine stations (Table 58).Milling in the Susitna/Yentna confluence might have been responsible.Pinks migrated more slowly between Sunshine and Talkeetna stations than between Talkeetna and Curry stations.Again,the difference might have been due to milling,this time in the confluences of the Talkeetna,Susitna and Chulitna rivers.Migration was slower in even years than in odd years.

No age information was collected for pink salmon because they are almost exclusively two-year-olds.Fish lengths averaged 419 to 474 mm,with no major differences between odd and even years (Table 59).Because this species has essentially no freshwater rearing,between-and within-year length variation may be due to ocean growth.Generally,males were slightly more abundant than females in both reaches,with no major distinction between odd and even years (Table 59).

Migration speeds were slower in the lower river than in the middle river (Table 63).The slower migration speeds in the lower river may be associated with milling at major river confluences. Returning chum ranged in age from two to six years old (Table 64).Most were four-year-olds,except in 1983 when the majority were five-year- olds.Average fish lengths ranged from 584 to 609 mm for all four years (Table 65).Generally males were more plentiful than females.

In the lower reach above the Susitna/Yentna confluence,1984 surveys documented five spawning sloughs,used by about 900 chums.Spawning extended from mid-September to mid-October,probably peaking the last week of ,September.Ninety percent of that spawning occurred in Cache (RM 96.0)and Musher (RM 95.2)sloughs. Chum salmon used 10 of 17 lower-reach stream mouths for passage,and to a lesser extent for spawning.Approximately 100 to 225 chum spawned in mouth areas in 1984.Mo~t stream-mouth spawning occurred from the first to third weeks of August. In the middle reach,chum spawning also occured in the mainstem,sloughs and streams. Most middle-reach mainstem spawning was found in 1984 surveys (Table 66).However.during 1981-82 surveys,visibility was poor in the mainstem due"to high flows and turbidity,and some spawning areas 141 probably were missed.In addition,more spawning in the mainstem probably occurred in 1984 than other years due to the record-high escapement.In the last four years,almost all mainstem spawning areas were above Curry Station.Spawning occurred in September and early October,with the peak between the second and third weeks of September.

Since 1981,twelve str~ams in the middle reach have been used for spawning by chum salmon,with highest incidences in Indian River and Portage Creek.Spawning in middle-reach streams occurred fro~the fourth week of July to the second week of September,and peaked ln the last two weeks of August.Based on index counts,the highest stream escapements were in 1984 (Table 67). In 1983 and 1984,Indian River and Portage Creek spawning surveys were expanded beyond the index areas to the full 1engths of the streams. Expanded surveys were not performed at other streams because essentially all spawning occurred in index areas.At Indian River,the majority of sp~wning occurred in the index area (Tables 67 and 68).At Portage Creek,most spawni ng occurred above the index area.These creeks averaged 92 percent of the enti re chum mi ddl e-river stream escapement for the last two years,which was about 3,000 fish in 1983 and 7,600 fish in 1984. Thirty-two sloughs in the middle reach have been u~Qd by chum salmon in the last four years (Table 69).In order of importance,most of the spawning was in sloughs 9,8A,11 and 21.Slough escapements totaled 5,200 chum in 1981,4,500 in 1982,2,950 in 1983 and 14,650 in 1984. The four-year average escapement was 6,800.All slough escapements were calculated using 1983 and 1984 observed-residence data and survey counts.The average observed residence of a chum in a slough was 6.9 days in 1983 and 6.8 days in 1984.Observed-residence studies were not conducted prior to 1983. 142 - - ..... ~, - - - ,}1 j 1 };1 "~ 1 )}j 1 )~) Table 67.Peak .urvey counts and percent distribution of chum salmon in stream index reaches above RM 98.6 in 1981-84. 1981 1982 1983 1984 Percent Percent Percent Percent Average \ River Peak l Distri-Peak l Distri-Peak 1 Distri-Peak l Distri-Distri- Stream Mile Count bution Count bution Count bution Count bution bution Whiskers Creek 101.4 1 0.4 0 0 0 0 0 0 * Chase Creek 106.9 1 0.4 0 0 0 0 1 0.1 * Lane Creek 113.6 76 31.5 11 0.6 6 0.5 31 1.7 2.5 Lower McKenzie Creek 116.2 14 5.8 0 0 1 0.1 23 1.3 0.8 Little Portage Creek 117.7 0 0 31 1.8 0 0 18 1.0 1.0 5th of July Creek 123.7 0 0 1 0.1 6 0.5 2 0.1 0.2 Skull Creek 124.7 10 4.2 1 0.1 0 0 4 0.2 0.3 Sherman Creek 130.8 9 3.7 0 0 0 0 6 0.3 0.3 .....4th of July Creek 131.1 90 37.3 191 11.0 148 12.0 193 10.6 12.4.j:::o w Indian River 138.6 40 16.6 1~346 77.5 811 65.6 1 ~272 70.0 69.0 Jack Long Creek 144.5 0 0 3 0.2 2 0.2 4 0.2 0.2 Portage Creek 148.9 0 0 153 8.8 262 21.2 262 14.4 13.5 TOTALS 2 241 99.9 1,737 100.1 1,236 100.1 1,816 99.9 100.2 Peak count includes live plus dead fish. 2 Percent distribution totals may not equal 100 due to rounding errors. *Trace.

Spawning in middle-reach sloughs extended from the second week of August to the 'last week of September.Peak spawning occurred in the first week of Septlember,about one to two weeks later than in nearby streams. Egg retention at sloughs in the middle river averaged 114 and 463 eggs per female in 1983 and 1984.Median retentions were five and .one eggs per female respectively.The higher figure may have been associ ated with the record-hi gh escapement.Bakka 1a (1970)reported that egg retention normally increased with spawner density.Egg retention was not studied in 1981 or 1982. 4.5 Coho Salmon The Susitna River is the largest single coho-salmon-producing system in Upper Cook Inlet,annually contributing about 50 percent of the commercial harvest in the district (AOF&G 1982,1983).Susitna River coho also contribute to a growing recreational fishery (Mills 1983). Within the Susitna River drainage,there are a minimum of 25 spawning populations,most of which spawn in the lower reach below Sunshine Station (AOF&G 1982,1983). Since 1981,Susitna River coho escapements have been 37,000 (1981), 80,000 (1982)and 24,100 (1983)(Barrett et al.1984).These estimates do not include escapements to systems below Sunshine Station except the Yentna River.Based on population studies at Flathorn Station,the 1984 Susitna River coho escapement was 190,100 fish (Section 3.5). 145 ---------------,---------------------,--- Lower-river coho escapements for the last four years to Yentna Station averaged 19,600 fish and to Sunshine Station 43,900 fish (Figure 76). The combined 1984 escapement to those stations was the highest on record and 80 percent higher than the four-year average (Figure 77).This was due mainly to the large escapement at Sunshine Station.The Flathorn escapement in 1984 was about 190,100 fish or 40 percent higher than the same-year combined Yentna and Sunshine escapement. Since 1981 annual middle reach escapements to Talkeetna Station have averaged 5,700 coho,and to Curry Station 1,600 coho.The 1984 escapement to Talkeetna Stati on was about double the previ ous record escapement of 1982.However,the 1984 Curry Station escapement,while above average,was 200 fish less than the 1982 record escapement, indicating that most of the 1984 escapement increase was downstream of Curry. Coho escapement to the middle river was largely comprised of milling fish which ultimately spawned in the lower reach.In 1981 radio telemetry studies,three of six cohos tagged at Talkeetna Station and three of four tagged at Curry Station spawned below those sites.In 1982 radio telemetry studies,10 of 11 coho tagged at Talkeetna and one of five tagged at Curry spawned downstream.There was no radio telemetry study or full survey coverage of spawning areas in 1983,but 1984 spawning area surveys indicated that 75 percent of the Talkeetna Station escapement and 45 percent of the Talkeetna Station escapement were milling fish.Proximity to the confluence of the Talkeetna, Chulitna and Susitna rivers probably accounts for the high Talkeetna milling percentage. The reaches upstream of Sunshine Station supported most of the coho return.In 1984,10 percent of the basin-wide escapement returned to spawn within the Yentna River drainage,40 percent returned to areas between the Yentna River mouth and Sunshine Station,and 50 percent returned to spawning grounds above Sunshine Station.Specific spawning areas within the lower and middle reaches are discussed later in this section. Coho were abundant in the lower river from the third week of July to the third week of August.In the middle reach,they were abundant from the last week of July to the first week of September (Figure 78). In 1984,most coho destined for Yentna and Sunshine stations migrated in the east channel past Flathorn Station.Apparently~Yentna populations crossed to the west channel of the Susitna River before the Yentna River confluence.Annual migrations past Yentna and Sunshine were mainly along the south and east banks.At Talkeetna Station,most coho ran along the west bank.Migration was evenly divided between east and west banks at Curry. Coho salmon migration rates in the lower river were slower between Flathorn and Yentna stations than between Flathorn and Sunshine stations (Table 70).The slower migration rate may be associated with milling at the Susitna/Yentna confluence.Fish migration rates between Sunshine and Talkeetna stations were slower than between Talkeetna and Curry stations.This was probably due to milling during passage through the confluence area of the Talkeetna,Chulitna and Susitna rivers. 146 - ~I - CURRY STATION e 1981 •1982 lSJ 1983 f.J TALKEETNA STATION oo ~...

The average coho fecundity at Sunshine Station in 1984 was 2,800 eggs per female.This was slightly greater (by 360 eggs per female)than reported by Hart (1973). Coho spawning in the lower mainstem was limited.No spawning was documented in 1981 and 1982;no surveys were conducted in 1983.In 1984,approximately 330 coho spawned in two mainstem sites located at RM 87.5 and 94.5.Spawning occurred during the last two weeks of September and the first two weeks of October. Sloughs were rarely utilized by coho.One site (RM 57.0)was verified when lower-river slough surveys were instituted in 1984.Six coho were observed spawning there on October 13.Four years of mi ddl e-river surveys confirmed only one site at Slough 8A,where two coho were observed spawning on October 2,1982. Susitna River coho salmon spawned almost exclusively in lower-and middle-river streams.In the lower river,they were observed in 11 of the 17 stream mouths surveyed in 1984.Coho uti 1ized those areas for either passage or milling,but no spawning was observed. In the middle river,coho salmon utilized 12 streams.In order of importance,the major spawning occurred at Gash Creek,Whi skers Creek, Chase Creek and Indian River (Table 73).In 1984,coho spawning occurred at the mouths of Whiskers,Slash,Fourth of July and Portage creeks.Stream-spawning in the middle river occurred from the first week of September to the second week of October,and peaked in the last tWQ weeks of September during the study years. The 1984 surveys of major coho streams in the middle reach included each streams entire spawning range (Table 74).Based on the peak counts of those surveys,stream escapements to Indi an Ri ver and Whi skers Creek, the two most important coho producers,were 930 and 602 fish.The 1984 escapement to all middle-reach streams was an estimated 2,900 fish. 151 Table 73.Peak survey counts and percent distribution of coho salmon in stream index reaches above RM 98.6 in 1981-84. 1981 1982 1983 1984 Percent Percent Percent Percent Average % River Peak l Distri-Peak l Distrf-Peak l Distri-Peak l Distri-Distri - Stream Mile Count bution Count bution Count bution Count bution bution Whiskers Creek 101.4 70 15.3 176 27.8 55 42.3 117 16.3 21.5 Chase Creek 106.9 80 17.5 36 5.7 1 0.8 239 33.2 18.2 Slash Creek 111.2 --6 1.0 2 1.5 5 0.7 0.8 Gash Creek 111.6 141 30.8 74 ,11,7 19 14.6 234 32.6 24.0 Lane Creek 113.6 3 0.7 5 0.8 2 1.5 8 1.1 1.0 Lower McKenzie Creek 116.2 56 12.2 133 21.0 18 13.9 24 3.3 11.9 Little Portage Creek 117.7 --8 1.3 0 0 0 0 0.6 4th of July Creek 131.1 1 0.2 4 0.6 3 2.3 1 0.1 0.4 .....Gold Creek 136.7 0 0 1 0.2 0 0 0 0 0c.n N Indian River 138.6 85 18.6 101 16.0 27 20.8 70 9.7 14.6 Jack Long Creek 144.5 0 0 1 0.2 1 0.8 0 0 0.2 Portage Creek 148.9 22 4.8 88 13.9 2 1.5 21 2.9 6.8 TOTALS 2 458 100.1 633 100.2 130 100.0 719 99.9 100.0 Peak count includes live plus dead fish. 2 Percent distribution totals may not equal 100 due to rounding errors. *Trace.

AS Page A106 AI07 A73 AI09 AIID Alll AIlS - - - - INTRODUCTION The proposed hydroel ectri c project may impact fi sh resources in the lower Susitna River through changes in flow,water quality and temperature in the slough,side channel,main channel,and stream mouth habitats.Information on the di stribution,timi ng and magnitude of salmon spawning in these habitats is necessary to assess impacts and to plan appropriate mitigation measures. OBJECTIVES 1)Identify distribution,timing and abundance of salmon spawning in main channel,side channel,slough and stream mouth habitats o~the lower Susitna River (RM 28.0 -98.6).. 2)Identify the general habitat characteristics of those areas utilized by spawning salmon.

No attempt was made to distinguish between velocity and warm water leads.Salmon,particularly chum,often select warm water upwelling areas for spawning (Vining et al.1985;Bakkala 1970;Kogl 1965'. Aerial surveys in the lower-river study reach (Figure 2)were conducted weekly from August 21 to October 17,1984 to locate salmon spawning sites (Plate 1).Suspected spawning sites identified from the air,were resurveyed on foot to verify spawning.Verification was determined through visual observation of salmon redds (Plate 2)and/or locating salmon egg~in the substrate with standard egg pumping equipment (Plate 3).Spawn 1 og a reas were mapped with the spec i es,numbers of 1i ve and dead salmon,number of redds and upwelling noted.More detailed methods can be found in Barrett et al.(1985). Stream Mouth Habitats Seventeen lower-river stream mouths between RM 28 and 98.6 were surveyed weekly from July 21 to October 1,1984 (Table 1).The primary objectives of these surveys were to determine the distribution,timing and magnitude of salmon spawning.

Surface substrate was assessed in accordance wi th standard procedures (ADF&G 1983dL A profile of each stream mouth was developed by measuring the depth,at two foot intervals,along one or two transects.Stream mouth profiles were dete~,ined for two Susitna River discharges. RESULTS AND DISCUSSION Mainstem Habitats The Susitna River mainstem is comprised of main-channel and side-channel habitats.Sautner et al.(1984)describes the main channel habitat in the middle reach of the Susitna River as being characterized by high water velocities and well-armored streambeds.~1ain-channel habitat downstream of the Chulitna River confluence has different characteristics than similar habitat in the middle reach.The main channel in the lower reach is highly braided and in places,not easily distinguishable.Main channel substrates in the lower river are generally less armored and less stable than those of the middle river. As a result,the morphological character of main-channel habitats in the lower river often changes during high mainstem discharges.Side-channel habitat is characterized by shallower depths,lower velocities and smaller streambed materials than the adjacent habitat of the main channel river (Sautner et al.1984).Side channels in the lower river are often difficult to distinguish from the braided main-channel habitats.Side-channel habitats have generally narrower channels that are separated from the main channel by stable vegetated islands.For the purposes of this study,however,both main channel and side-channel habitats have been classified as mainstem habitats since our ability to distinguish between the two habitat types on the basis of their physical and hydraulic characteristics was limited. Survey conditions prior to lat~September were poor due to high water and turbidity levels.As a result,earlier surveys may not have documented all of the spawning activity present.A flood in early September eliminated signs of spawning prior to that time.Lower water and turbidity levels beginning in late September improved visibility conditions which increased the frequency and accuracy of spawning observations. Twelve mainstem spawning sites were identified in 1984 (Figure 3L Chum salmon spawned in 11 of these sites and coho salmon spawned at two. The other salmon species were not observed spawning in the mainstem. Maps and habitat descriptions of the 12 spawning sites can be found in Appendix A.

A conservative estimate of between 2,600 too 3,900 chum salmon spawned at mainstem sites in the lower Susitna River.This represents between 0.3 to 0.5 percent of the 1984 Susitna River escapement (Barrett et ale 1985).Observed residence studies conducted in 1983 and 1984 have determined that a peak count represents about 50 percent of a spawning escapement.The highest fish count (live and dead)for mainstem sites was probably not made at the peak spawning period due to high mains tern discharges and turbidity.Using this assumption,an expansion factor of three was used to detennine the upper 1imit of the range (Barrett et ale 1985).Coho salmon exhibited a range of 200 to 400 fish spawning in two mainstem sites.This is between 0.1 to 0.2 percent of the 1984 Susitna River escapement. The majority of the chum salmon spawning occurred at:Trapper Creek side channel (RM 90.3l);Sunset side channel (RM 87.0R);the Chulitna River mouth (RM 98.6l)and Circular side channel (RM 75.0L). Collectively,these sites supported 90 percent of the spawning while the other eight sites had the remaining 10 percent,based on survey counts. Trapper Creek side channel had 96 percent of the coho salmon spawni ng while Sunset side channel had the remaining four percent,based on survey counts.Surveys conducted by the Aquati c Habitat and Ins tream Flow Study of the Susitna Hydro Project indicated that several of these sites may °have had more util ization than our survey counts indicate (Bigler 1985a). Upwelling (Plate 4),bank seepage (Plate 5)or open leads in winter were observed at 10 of the 12 spawning sites.The major chum salmon spawning sites and the two coho salmon spawning sites all had associated upwelling or bank seepage.It is likely that some degree of upwelling occurs at the remaining sites although it was not detected during our surveys.Other studies have shown that chum salmon select upwelling areas in which to spawn (Vining et ale 1985;Bakkala 1970;Kogl 1965). Slough Habitats Slough habitats can be divided into two types:upland sloughs and side sloughs.The main difference between the two types is that the upstream end of an upland slough does not connect with the mainstem even at high mainstem discharges (Sautner et ale 1984).A feature that distinguishes side slough habitat from side-channel habitat is that side sloughs usually convey clear water from small tributaries and/or upwelling groundwater in an unbreached condition (Sautner et ale 1984).All of the slough salmon spawning sites located in this study fall in the side slough category. A26 - -I - - - "'" ..

A27 -,----------------'---~--------~--~----_.----------- Survey conditi ons encountered in slough surveys were simil ar to those encountered in the mainstem.Survey conditions improved as mainstem discharges fell in late fall ~which increased the frequency and accuracy of spawning observations. Spawning was observed in six sloughs (Figure 4)~five of which were used .by chum salmon and one by coho salmon.The other salmon species were not observed spawning in lower-river sloughs.t1aps and habitat descriptions of the six sloughs can be found in Appendix A. Slough spawning by chum and coho salmon was documented in late September and early October as visibil ity improved just prior to freeze up.,t.Lis probable /tha-t-earlter sp~~ning occurred.that was not obser'led-·dueto hlgtr-ma:fnstem discharges and turbidity.The peak of spawning in lower- river slough-sites appears to foll ow a pattern similar to the rna instem. Peak chum salmon spawning probably occurred the first two weeks of September and was essentially over by the second week in October. Similarly~the peak coho salmon spawning,in the single slough site, occurred during the second week of October. Using procedures outl ined in Barrett et al.(1985',it was estimated that 700 to 1,000 chum and 10 to 20 coho spawned in slough sites in the lower ri ver.Both of these ranges are 1ess than 0.1 percent of the Susitna River escapement. ~10st of the spawni ng occurred at Cache Creek 510ugh (RM 96.Ol)and Musher Slough (RM 95.2R).Collectively,these sloughs supported 90 percent of the spawning while the other three sloughs supported the remaining 10 percent as determined by spawning ground counts.The only slough found to have spawning coho salmon was Rustic Wilderness Slough (RM 57.0R),in which six fish and nine redds were observed. Four sloughs,in which salmon spawned~had associated upwelling~bank seepage or were identified as an open lead area.Cache Creek Slough~ which had most of the chum salmon spawning~had no visible upwelling or bank seepage.Cache Creek flows into the slough and probably provides adequate intragravel flows that attracted the spawning. Stream -Mouth Habitats Descriptions of individual stream-mouth habitat characteristics al'1d a summary of adult salmon use is provided in Appendix B.Also included in Appendix B a-e maps depicting the spawning areas within each stream mouth.Additional habitat and stream-mouth depth profiles are provided in Appendix D. The Deshka River was not specifically included in the survey program because hi gh densities of sport fi shermen use the stream mouth,and water depths and lack of clarity thwarted definitive results. Historically,chinook,sockeye,pink and coho salmon have spawned in this drainage (ADF&G 1982b).

Figure 4.Slough salmon spawning areas identified in the lower Susitna River between RM 28.0 and 98.6,1984 • A29 Chinook Salmon The chinook migration at Sunshine Station was essentially complete 15 days prior to the first survey on July 21 (Barrett et al.1985). Therefore,assessment of spawning and passage in stream mouths was not representative of the entire migration. Chinook salmon used five stream mouths for either passage to upstream spawning areas or as holding areas prior to continuation of their Susitna River migration.The most important were Birch and Montana creeks (Table 2 and Appendix Table C-3).Twenty-six of the 39 fish counted were at these stream mouths.

Chinook did not spawn in the five stream mouths they occupied (Appendix Table 8-1). The Deshka River,not included in the lower river survey program,was a major chinook-producing system.Spawning pr~bably did not occur in the mouth of the Deshka because a 1984 assessment of the substrate indicate a composition of primarily silt and sand,which is not preferred by chinook for spawning (Burner 1951).Passage through the mouth of the Deshka River began in May and probably ended,as in other lower-river stream mouths,sometime in August. A30 - Sockeye Salmon, Sockeye salmon were observed in eight of 17 lower-river streams surveyed between July 23 and October 1 (Appendix Table C-3).All sockeye observed during these surveys were second-run fish.First-run sockeye had completely passed Sunshine Station by June 28 and were known to spawn above Rf~28 in only the Fish Creek drainage (Tal keetna River System)(Barrett et al.1985). Sockeye salmon utilized eight lower-river stream mouths for either passage or holding.Most (88%)of the 608 sockeye were observed in Willow,Birch,Goose and Fish creeks (Table 3).Sockeye were present in stream mouths from July 23 to September 1 (Appendix Table C-3). Ashton and Trihey (1985)reported possible fish access problems into several lower-river streams at with-project flows.Sockeye occupied three of these areas:Goose and Rabideaux creeks and Fish Creek,which enters Kroto Slough.A combined 25 percent of the sockeye were observed at these stream mouths (Table 3). -Table 3.Sockeye salmon peak counts in stream mouths between R~1 28.0 and 98.6 in order of contribution,1984.

Ashton and Trihey (1985)identified five stream mouths,in which sockeye were observed,where with-project flows may moderately decrease the backwater area.These were Birch,Fish,Sunshine,Little ~lil1ow and Rabideaux creeks. ,~ A31 Sockeye salmon were not observed spawning in any lower-river stream mouths (Appendix Table B-1).Although the Oeshka River was not included in the survey program,there was probably no spawning at the mouth of this river because the substrate was primarily a silt-sand composition, not suitable for spawning (Burner 1951). Pink Salmon Lower-river streams supported most of the Susitna River basin pi nk salmon spawning in 1984.Approximately 60 percent of the 3.6 mill ion Susitna River pink escapement spawned in lower-river streams between Flathorn and Sunshine stations excluding the Yentna River (Barrett et ale 1985). In 1984,pink salmon used 12 lower-river stream mouths for either passage to upstream spawning areas or as holding areas during their Susitna River migration (Table 4 and Appendix Table C-3).A total of 5,941 fish were counted in these streams during peak surveys.Most (76%)were in Willow,Sunshine and Birch creeks.Pinks were observed in stream mouths from July 28 to September 9,and were most abundant during the first two weeks of August.Passage did not appear to be a problem at natural flows,but may be restricted during with-project flows at Caswell,Goose,Montana and Trapper creeks,whi ch coll ective ly accounted for 12 percent of the fish counted in stream mouths.

This was consistent with the results of previous Susitna River studies (ADF&G 1983b). Historically,pink salmon have used the mouth of the Deshka River for passage and possibly as a holding area (ADF&G 1982).Spawning probably do~s not occur in this stream mouth because the substrate was primarily comprised of silt and sand,not the preferred spawning substrate for salmon (ADF&G 1983b). Chum Salmon The lower river,between Fl athorn and Sunshine stati ons excl udi ng the Yentna River,supported about three percent of the 1984 chum salmon spawning.in the Susitna River basin (Barrett et al.1985). Chum salmon utilized 10 stream mouths for either passage to upstream spawning areas or as holding areas during migration (Table 6 and Appendi x Table C-3).Goose,Wi 11 ow and Sheep creeks were the most important of those,with 72 percent of the fish.Chum were present in lower-reach stream mouths from July 27 to September 24.Peak abundance was in the last week of August and the first week of September. Ashton and Trihey (1985)predicted potential fish-access problems into Caswell,Goose,Montana and Trapper creeks at with-project flows. Fi fty-three percent of the chum were located in these stream mouths (Table 6).

A34 ~ - - ~I Chum may have used the Deshka River mouth as a holding area,but there was no evidence of spawning there.The substrate·was a silt-sand composition unsuitable for spawning (ADF&G 1983b).There is no documentation of this species spawning upstream in the Deshka River drainage (ADF&G 1982). Coho Salmon Lower-river streams supported about 50 percent of the 1984 Susitna River basin-wide coho salmon spawning (Barrett et ale 1985). Coho salmon util ized el even stream mouths for either passage or as. holding areas (Table 8 and Appendix Table C-3).Most (84%)of the 1,430 fish counted were in Willow Creek.Coho occupied stream mouths from August 6 to September 27.Peak abundance occurred in the third week of August. Of the stream mouths utilized by coho salmon,Whitsol,Caswell,Goose and Montana creeks may have restricted access at with-project flows (Ashton and Trihey 1985).Those streams accounted for about 12 percent of the coho peak survey counts at lower reach stream mouths. Coho salmon did not spawn in any of the 17 lower-river stream mouths surveyed (Appendix Table B-1).Historically,the Deshka River has been utilized for passage and holding (ADF&G 1982).It was unlikely that coho spawned here because the substrate was comprised of mainly silt and sand,unsuitable for spawning (Burner 1951).

Slough Habitats All of the slough habitats found to contain spawning salmon in the lower Susitna River were in side sloughs.Alteration of channel morphology at high discharges may change a slough site to a side channel site.Poor visibility limited the accuracy of surveys until after late September. Six slough spawning sites were located in the lower river,five of these sites were used by chum salmon and one by coho salmon.It appears that the timing of spawning in the sloughs follows a similar pattern to that of the mainstem.Chum salmon probably peak during the first two weeks of September with coho salmon peaking during the second week of October. Between 700 to 1,000 chum salmon and 10 to 20 coho salmon are estimated to have spawned in sloughs~Only four of the sloughs were observed to have upwelling,bank seepage or open leads.Cache Creek may be providing adequate intragrave1 flow in one of the remaining sites. Stream Mouth Habitats Seventeen lower-river stream mouths were surveyed for adult salmon from July 21 to October 1.Pink salmon were most widely distributed, occupying 12 stream mouths and chinook occupying only five.Coho,chum and sockeye were observed in 11,10 and 8 stream mouths,respectively. Salmon were present in stream mouths from July 23 to September 27. Only pink and chum salmon spawned in lower-river stream mouths in 1984. Approximately 4,'=:00 to 9,000 pinks spawned in 10 stream mouths.Five stream mouths supported in the range of 100 to 225 chum spawners.Pinks spawned from July 28 to September 8.The peak occurred during the first two weeks of August.Chum salmon spawned from the second week of August through the third week of September.Peak spawffing occurred during the last week of August and first week of September. Both pink and chum salmon selected gravel-rubble substrates for spawni ng.Neither speci es spawned ins i It-sand substrates.Thi s was consistent with previous ADF&G Su Hydro study results (ADF&G 1983b). A36 - - .. - - - - - ...... Historically,chinook,sockeye,pink and coho salmon have passed through the Deshka River stream mouth enroute to upstream spawning areas (ADF&G 1982).Examination of the stream-mouth revealed a silt-sand substrate and therefore,it was concluded that salmon did not spawn here. A3? GLOSSARY Genera 1 characteri sti cs of habitat cl ass i fi cati ons that are associ ated with the Susitna River (adapted from Sautner et ale 1984). ...;;.S...;..id,;,;,;e;;..-...;;S;,.;.l..;;.o,;;;.ug~h..;....;.H,;,;;;a,;;;.b...;..it..;...a:;..t;;..;..:Consists of those portions of the Susitna River that usually convey water throughout the year.Both single and multiple channel reaches are included in this habitat category.Groundwater and tributary inflow appear to be inconsequential contributors to the overall characteristics of main-channel habitat.Main- channel habitat is typically characterized by high water velocities and well-armored streambeds. Substrates generally consist of boulder and cobble size materials with interstitial spaces filled with a grout-like mixture of small gravels and glacial sands. Suspended sediment concentrations and turbidity are high during summer months due to the influence of glacial melt-water.Discharges recede in early fall and the main channel clears appreciably in October. Mainstem Habitat:Consists of main-channel and side-channel habitats. Side-Channel Habitat:Consists of those portions of the Susitna River---------------tUh~a~t normally convey water during the open water season but become appreciably dewatered during periods of low main channel discharge.Side-channel habitat may exist either in well defined overflow channels,or in poorly defi ned channels fl owi ng th rough pa rt i all y submerged gravel bars and islands along the margins of the main channel river.Side-channel streambed elevations are .typically lower than the mean monthly water surface elevations of the main channel Susitna River observed during June,July and August.Side-channel habitats are characterized by shallower depths,lower velocities and smaller streambed materials than the adjacent habitat of the main-channel river. Side-Slough Habitat:This habitat is located in overflow channels~~~~~~~~b~e~tween the edge of the floodplain and the main channel and side channels of the Susitna River.It is usually separated from the main channel and side channels by well vegetated bars.An exposed alluvial berm often separates the head of the slough from main channel discharge or side channel flows.The controlling streambed/bank el evati ons at the upstream end of the side sloughs are slightly less than the water surface elevations of the mean monthly discharges of the mainstem Susitna River observed for June,July and August.At intermediate and low-discharge periods,the side sloughs convey clear water from small tributaries A3S - - - - - - and/or upwelling groundwater.These clear water inflows are essential contributors to the existence of this habitat type.The water surface elevation of the Susitna River generally causes a backwater area to extend well up into the slough from its lower end. Even though this substantial backwater area exists,the sloughs function hydraulically very much like small stream systems and several hundred feet of the slough channel often conveys water independent of mai nstem backwater effects.At high discharges,the water surface elevation .of,the mainstem river is sufficient to overtop the upper end of the slough.Surface water temperatures in the side sloughs during summer months are principally a function of air temperature,solar radiation,and the temperature of the local runoff. Stream Habitat:Consists of full complement of hydraulic and morphologic conditions that occur in the streams. Their seasonal flow,sediment,and thermal regimes reflect the integration of the hydrology,geology,and climate of the stream drainage.The physical attributes of stream habitat are not dependent on mainstem conditions. ";;,UJ,;.p...;..la;;;,.;n...;..d;;.....;;S...;..l,;;.ou.;;.gl',;,h.;.......H..;;;a...;..b...;..it.;.;a;;..;t;,,.,;..:Differs from side-slough habitat in that the upstream end of the slough does not interconnect with the surface waters of the main-channel Susitna River or it side channels even at high mainstem discharges. These sloughs are characterized by the presence of beaver dams and an accumulation of silt covering the substrate resulting from the absence of mainstem scouring discharges.

A44 ~, - - - APPENDIX A Site descriptions and maps of mainstem and slough salmon spawning areas located in the lower Susitna River between RM 28.0 and 98.6 in 1984. A45 l~ -- The following salmon spawning site descriptions are those located during 1984.They are ordered starting with the downstream most spawning site and moving upstream. RM 57.0R This is a slough spawning site located adjacent to the east bank side channel near the Rustic Wilderness subdivision (Appendix Figure A-I). It is the only slough site to be utilized by coho salmon.A survey on October 13,1984 located six live coho salmon and nine redds.Based on the number of redds,thi"s site was probably utilized by a greater number of salmon than were counted on this single survey.Upwelling was present throughout the spawning site. RM 62.1R This mainstem spawning site was observed immediately downstream of the mouth of Caswell Slough (Appendix Figure A-2).This site is separated from the main channel,at low discharges by an exposed gravel bar.A survey on October 9,1984 identified five redd sites with two live and six dead chum salmon.Upwelling was also observed.The upwelling observation coincides with the open lead observations made in this area by R&M Consultants,Inc.on March 18,1983 (Coffin 1983). Rt1 63.?R This is a minor slough spawning site located near the mouth of Caswell 9""Creek Slough (Appendix Figure A-3).Four 1ive chum salmon and three redds were observed during a survey conducted on October 11,1984. Upwelling was observed in the vicinity of the spawning area.The influence of Caswell Creek Slough may also have had an influence on fish selecting this as a spawning site. RM 71.6R Twel ve redds were observed at RM 71.6R on October 9,1984 (Appendix Figure A-4).These redds were assumed to be chum salmon redds.No live fish were observed but eight dead chum salmon were in this vicinity. This side channel site,located near the head of Sheep Creek Slough,is separated from the main channel Susitna River by gravel bars that are exposed at low discharges.Bank seepage was observed at this site. RM 73.9C A main et.~nnel chum salmon spawning site was located at RM 73 ..9C,near Goose Creek Slough (Appendix Figure A-5).It is located in the center of the channel on a gravel bar disected by the mainstem Susitna River. Only sma 11 portions of thi s compl ex are vegetated,indi cating frequent inundation by the mainstem.A survey conducted on September 25,1984 found seven redd sites and three dead chum salmon.The number of redds indicates that the site was utilized by a greater number of salmon than were observed on the si ng1 e survey.The R&H survey i ndi cated an open lead in this area.No upwelling was observed in this site.No observed upwelling and the site being directly on the mainstem indicates that the open lead may be velocity related. A46 ____."'=";:;;1 ......3i I~ -- RM 74.5R This site is located at the upper end of Goose Creek Slough (Appendix Figure A-5).It is a chum salmon spawning site with 12 redds counted duri ng a survey on October 8,1984.Whi 1e no upwell i ng was observed, the area has open leads,indicating the presence of upwelling. RM 75.0L This chum salmon spawning area,known as Circular Side Channel,is bordered ~y stable vegetated islands (Appendix Figure A-6).The average water depths in the spawning areas range from 0.5 to 4 feet.There are two main spawning areas that are separated by a 75 foot riffle in which no spawning occurred (Bigler 1985b L Upwell ing and bank seepage was observed throughout the area.Approximately 30 redds and 68 live and 21 dead chum salmon were observed on September 25,1985. RM 79.2L Site 79.2L is a chum salmon spawning location off the mouth of Sauna Slough (Appendix Figure A-7).The site is separated from the mainstem by a sparsely vegetated gravel bar.Seven redds and 18 chum salmon were observed on October 8,1984.The area has an open lead and bank seepage was observed approximately one half mile upstream from the spawning site. RM 87.0R This site is located in the Sunrise -Sunset Side Channel area (Appendix Figure A-8).It had the second highest usage by chum salmon of all mainstem sites found in 1984.This high usage is reflected in peak live salmon counts of 173 fish and 48 redds observed.Numerous open leads were observed in the area indicating possible presence of upwelling. RM 87.5R The upper Sunset Side Channel was utilized by a small number of coho salmon (Appendix Figure A-9).Five coho salmon and three redds were observed at this site on September 25,1984.Open leads are present at this site.The open leads may be due to upwelling or the influence of Birch Creek Slough,found immediately upstream. RM 88.7R A site upstream of the mouth of Birch Creek Slough is located directly on the mainstem at RM 88.7R (Appendix Figure A-IO).The adjacent bank is high and steep with bank seepage present.Twenty three chum salmon and 11 redds were observed during a survey conducted on October 9,1984. RM 89.5R This slough spawning site utilized by chum salmon is located approximately one mile upstream of the mouth of Birch Creek Slough A47 (Appendix Figure A-10).Peak counts of 12 churn salmon and four redds were observed on October 9,1984.While no upwelling was observed in this specific site,bank seepage was observed in chum salmon spawning sites located upstream and downstream of this site. RM 90.1R A side channel habitat located at RM 90.1R was utilized by spawning chum salmon (Appendix Figure A-10).Bank seepage was observed during surveys of this site.A survey on October 9,1984 observed 19 redds and 41 chum salmon.Based on the number of redds and live fish observed this site is the third most important mainstem spawning location in the lower reach. RM 90.3L A side channel located near Trapper Creek from RM 9?.OC to RM 94.5L was the most important mainstem spawning site located (Appendix Figures A-ll and A-12).The channel is located along the left bank,separated from the main channel by a broad,sparsely vegetated gravel bar.A total of 90 redds were observed at this site.Due to the overlap of areas utilized by spawning chum and coho salmon,it was impossible to differentiate redds between the species.Surveys conducted between September 23 and October 2,1984 observed 538 live chum salmon and 75 1 ive coho salmon.Upwell ing was observed extensively throughout this site.An aerial survey conducted February 18,1985 found this siteoto be the only one in the lower reach (RM 60-98)with open leads at -40 F. Temperatures at -20 F and higher were warm enough to create numerous open leads throughout this lower river reach. RM 95.0C A minor chum salmon spawning site was located at RM 95.0C (Appendix Figure A-12).A single chum redd with eggs and three 'live chum salmon were found in a pool behind a beaver dam.Part of this area is vegetated indicating some present stability.No evidence of upwelling was observed. RM 95.2R This chum salmon spawning site is located in Musher Slough (Appendix Figure A-12).It is the most important slough spawning site in this reach with 41 redds and 84 live churn salmon observed on September 18, 1984.Bank seepage was observed at this site. RM 95.8L This slough site is directly across from Musher Slough (Appendix Figure A-12).It is called Cache Creek Slough since Cache Creek enters the left bank at the upper end of the slough.Personnel conducted a survey on September 27,1984 and counted 160 live chum salmon but only 4 redds. The number of live fish to number of redds ratio is low compared to other sites.The chum salmon located at this site may have been milling A48 • - ~I i~ - prior to moving to other spawning sites or may have spawned at a later date.No upwelling was observed at this site but the influence of Cache Creek may make conditions suitable for chum salmon spawning. RM 98.6L Four individual chum salmon spawning sites were located in the braided channels at the mouth .of the Chulitna River (RM 98.0L)(Appendix Figure A-13).Collectively,this is the second most productive site located in 1984..A total of 51 redds and 116 chum salmon was observed during a survey conducted on October 9,1984.Only one of the spawning sites had observed upwelling associated with it.The entire area is unstable due to yearly flood events.Sites utilized this year may be unavailable to spawning salmon in following years.
