The Alaska Power Authority (APA) proposes construction of two hydroelectric dams at Watana and Devil Canyons on the upper Susitna Ri'!er (Figure A). The Alaska Department of Fish and Game (ADF&G) has been contracted by APA to access the fisher~· resources that might be empacted by the proposed hydroelectric project. The APA-ADF&G contract, initiated in November 1980, is still in effect. This is one of a series of AOF&G reports in 1985 that will be submitted to A?A. This document only address~s the adult anadromous fish investigations contracted for the open water period of May through October, 1984 and it covers the following Pacific salmon species: Pacific Salmon Chinook Salmon Sockeye Salmon Pink Salmon Chum Salmon Coho Salmon Oncorhynchus ~ Q.:. tshawytscha ·o. nerka ~ gorbuscha 0. keta --- 0. kisutch Questions -pertaining to this report should be directed to: Alaska Power Authority 334 West 5th Avenue Anchorage, Alaska 99501 Telephone (907) 279-6611 . -ii- I J I 1 [ I I I I I I I I I I I I I I I I I I I TABLE OF CONTENTS PREFACE •••••••••••••••••••••••••••••••••••••••••••••••••••••••••• TABLE OF CONTENTS •••••••••••••••••••••••••••••••••••••••••••••••• LIST OF TABLES •••••••••••••••••••••••••••••••••••••••••••••••••• LI ST OF FI GURES ••••••••••••••••••••••••••••••••••••••••••••••••••• LI ST OF APPEND I X TABLES ••••••••••••••••••••••••••••••.•••••••••.

The emphasis of the 1984 program was quantifying Susitna River salmon escapements and salmon spawning activity in the Susitna River main channel and directly associated streams, sloughs and side channels. More definitively, the objectives of the 1984 program separated by lower and middle Susitna River reach were: A. Lower River ((Intertidal RM 0.0 to Chulitna River confluence (RM 98.6)] 1. Define the abundance, seasonal timing and stock characteristics of the 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). In addition evaluate the same parameters for chinook salmon at Sunshine Station. 2. Define where, when and extent of the salmon spawning in the sloughs, main channel, side channels and stream confluence areas of the Susitna River between RM 28 and 98.6 . B. Middle Riv~r ~lChulitna River confluence (RM 98.6) to upper Devil Canyon (RM 161.0)] 1. Define the abundance, seasonal timing and stock characteristics of the chinook, sockeye, pink , chum and coho salmon escapements to the Susitna River at Talkeetna {RH 103) and Curry {RH 120) stations. 2. Define where, when and extent of salmon spawning in the Susitna River main channel, side channels and associated streams and sloughs between RM 98.6 and 161.0. In conjunction, determine the average resident time (observation life) of sockeye and chum salmon as required to quantify the total escapements of these species to the middle river reach slough s . -2- I I 1 I I I I I I I I I I I I I I I I I I I 2.0 METHODS 2.1 Main Channel Escapement Monitoring In 1984 salmon esca~ements were monitored at five main channel locations on the Susitna and Yentna rivers (Figure 1). In the lower Susitna River reach [Intertidal (RM 0.0) to Chulitna River (RM 98.6)] a tagging site was operated at RM 22 (Flathorn Station), a sonar site at TRM 04 (Yentna Station) on thP. Yentna River (RM 28) and a second tagging site at RM 80 (Sunshine Station) between Montana Creek and the George Parks Highway bridge. On the middle Susitna River reach [Chulitna River to upper Devil Canyon (RM 161.0)] a tagging station was operated at RM 103 (Talkeetna Station) and another at RM 120 (Curry Station). With the exception of Flathorn Station, a new tagging s i te this year, the other four monitoring stations were at the same river mile locations in 1984 as in 1981 and 1983. The five lower and middle river escapement monitoring stations in 1984 were operational according to the schedule in Table 1. At Flathorn (RM 22) and Sunshine (RM 80) stations four fishwheels were operated at each. At Yentna Station (TRM 04), two side scan sonars (SSS) and two fishwheel s were run concurrently. In the Susitna River middle reach, four fishwheels at Talkeetna Station (RM 103) and two fishwheels at Curry Station (RM 120) were ope rated. The specific placement sites of the 16 fishwheels and two sonars at the five sampling stations can be found in Appendix 1. -3- Figure 1.

The sonar installation and operating procedures followed were in accordance with the manufacturer's operational manual (Bendi x Corporation, 1980). Except for occas i ona 1 , heavy debris flows associ a ted with extreme high water the two sonar cou nters at Yentna Station were run continuously, 24 hours per day, through the 1984 season • . The two fishwheels, one near each so nar off the north and south Yentna River banks were operated a minimum of 12 hours daily during the season for apportioning the sonar counts by spec ies and for tag recovery data from Flathorn Station sited 10 miles downstream . The sonar mo ni tori ng and apportioning methodology followed thi s season can be found in -Barrett et al, 1984 . The 14 fishwheels used at the four tagg i ng locations on tne Susitna River main channel and the two operated at Yentna Station sonar site (TRM 04) i n 1984 were of a 1981 design by ADF&G/Su Hydro staff. The -5- construction and operating specifications of these wheels can be found in the Phase 1 and II AOF&G/Su Hydro Adult Anadromous reports (AOF&G, 1981 and 1982). The tagging station fishwheels were run 24 hours per day this season except for occasional down time for maintenance, debris problems and high catches that exceeded manpower capabilities. Each of these fishwheels was sampled for catch four or more times daily. All fishwheel caught salmon at Flathorn (RM 22), Sunshine (RM 80), Talkeetna (RM 103) and Curry (RM 120) stations were tagged and released except for fish which fell into one or more of the following categories: 1. fish that visually appeared lethargic or st~essed . 2. post-spawning condition fish. 3. fish previously tagged. 4. 90~ of the pink salmon at Flathorn and Sunshine stations, and 50~ of the pink salmon caugh ' at Talkeetna and Curry stations. 5. chinook salmon at Flathorn Station, and chinook salmon less than 351 mm in fork length (F L) at the other three stations. These fish were released without being tagged. However, the fish which were reca;>tured from other tagging stations were first checked for species identification and tag type, color and number before being released. In 1984 two tag types were used at the tagging stations : Petersen disc and Fl oy FT -4 spaghetti tags. The chi nook salmon were tagged with Petersen disc tags, and the sockeye, pink, chum and co.,o salmon were -6- ' I I I I I I I I I I I I I I I I I I I I tagged with the spaghetti tags . The exception was at Curry Station (RM 120} where Petersen disc tags were used exclusively . In addition a number of Petersen disc tags used at Curry Station were labeled with full size sequentia 1 numbers. These were used in marking sockeye and chum salmon for observation life (Section 2.2.2). A percentage of the tags used at all the stations were numbered to provide migrational travel time. The methodology used to implant the Petersen and spaghetti tags can be found in the Phase I , AOF&G/Su Hydro Adu 1t Anadromous report, (AOF&G, 1981}. At each sampling station on the Susitna and Yentna rhers in 1qe4 a representative age, length 11nd sex composition sampl P wa!; collected daily for each salmon species as follows: Chinook salmon: An age, length and sex sample collected daily from 30 consecu t ively (regardless of size) caught fish. Except at Sunshine Station where the sample was 30 consecutively caught fish from the east and west bank fishwheels. Sockeye salmon: An age, length and sex sample collected ~~ily from 30 consecutively (regardless of size} caught fish. Except at Flathorn Station where the sample was 30 consecuti~ely caught east channel fish and 30 consecutively caught west channel fish. -7- Pink salmon: A 'length and sex sample collected daily from 30 consecutively {regardless of size} caught fish. Chum salmon: An age; length and sex sample collected daily from 20 consecutively (regardless of size) caught fish. Coho salmon: An age, length and sex sample collected daily from 20 consecutively (regardless of size) caught fish. The procedures followed in 1984 for salmon age, length and sex composition sampling can be found in Barrett et at, 1984. In 19B4 at Sunshine Station (RM 80) 25 coho salmon were sampled for fecundity. The sample was taken from the length (FL) ranges of female coho salmon available from the east and west bank fishwheels on August 22. The collection procedures for sampling the age , length and weight, and determining the fecundity of each female f ish sampled can be found i n Barrett et al, 1984. 2.2 Spawn ing Ground and Tag Recovery Survey~ In 1984, the salmon spawning ground and tag recovery s urvey work was divided by lower and middle Susitna river reach. An except i on wa s a chinook salmon escapement index survey program conducted drainage wide of pre-selected spawning areas which has been ongoing annually since 1976 by ADF&G, Region II, Sport Fish Division staff (ADF&G, 1981). In 1984, they performed the selected chinook salmon surveys below RM 98.6 -8- l l I I I I I I I I I I I I I I I I I I I I I I I I between mid Ju ly and mid August with some assistance by AOF&G, Su Hydro staff. The surveys upstream of RM 98.6 were performed exclusivel y by Su Hydro staff between July 21 and August 18. The index surveys bel ow RM 98.6 were conducted by helicopter, foot, fixwing aircraft and inflatable raft depending on access while the surveys perforr.~d abo ve RM 98.6 were performed by helicopter and foot (Section 2.2.2). The following subsections outline the other 1984 salmon spawning ground and tag recovery survey work by Su Hydro Adult Anadromous staff in the lower and middle Susitna River reaches . 2.2.1 Lower Reach The lower reach streams listed in Table 2 were surveyed wet:kly for salmon presP.nce by foot and occasionally by helicopter from July 21 to October 7, 1984 . The survey reach for each stream was the one-third mi le area from the mouth. Table 2. Lower reach Sus i tna River streams surveyed weekly from July 21 to October 7, 1984.

Areas suspected of supporting salmon spawning were ground checked by foot and boat be tween schedul2d surveys . The suspected areas were considered s pawn i ng sites when one or more of the following criteria was noted: , 1. Visual identifi cati on of one or more actively mating fish pairs. 2. One or more distinct redds. 3. One or more suspected redd locations producing 1 ive eggs through mechanical excavation with a shovel or a backpack mounted, Homelite two cycle, single stage water pump and attendant circular st~nding screen cod end net . The one-third mile reach of the streams listed in Table 2, and spawning area(s) in lower river reach sloughs, and main channel and side channel habitats were mapped at least once in the 1984 season relative to general habitat characteristics. Parameters recorded included upwelling presence, surface flow and depth. Substrate descriptions were also recorded at the streams using the follow i ng classification: silt--very fine sand--fines small gravel--l /2"-1N large gravel--1"-3" -10- rubble-e--3"-5" cobble 5"-10" bou l der-10" or larger ' I I I I I I I ~ I I I I I I I I I I I I I I I I I I More precise evaluation of substrates in stream mouths were performed as time permitted using a McNeil sampler and sieves. Tag recovery surveys were performed by the crews also a ~ time permitted and when visibility in the streams, sloughs and main channel allowed accurate distinction of tagged and untagged fish. Routinely on the streams, the crew extended their survey beyond the one-third mile reach to a point three-quarters of a mi 1 e from the stream mouth for tag to untagged data and determining general habitat characteristics. 2.2.2 Middle Reach In 1984 salmon spawning surveys were conducted between July 21 and October 14 in the middle Susitna River reach. Specific chinook salmon surveys were made between July . 21 and August 18 of a 11 known and suspected spawning streams in the reach. Each stream was generally surveyed twice in this period by helicopter or on foot, where feasible, to the upper limit of fish migration. From August 6 to October 11, sloughs and streams of known and suspected adult salmon use above RM 98.6 were surveyed near weekly. The sloughs were surveyed on foot over t heir entire d~stance, and the stream~ were surveyed to standard index markers on foot. The exceptions were Indian River (RM 138.6) and PJrtage Creek (RM 148.9) which were surveyed beyond the index markers to the upper salmon mitigation limit. The three streams Cheechako Creek (RM 152.4), Chinook Creek (RM 157 .0) and Devil Creek (RM 161.0), all located in Devil Canyon, were surveyed by helicopter to their upper spawning limit. -11 - Sloughs Moose (RM 123.5), A• (RM 124.6), SA (RM 125 .1) and 11 (RM 135.3) were more intense 1 y surveyed than the other s 1 oughs above RM 98. 6 between August 16 and October 4. The surveys of these s 1 oughs were routinely conducted at three day intervals to additionally determine the observation 1 ife of sockeye and chum salmon. They were performed on foot, and the observers used polarized glasses and polarized 7x35 Bushnell binoculars for identification of individually marked sockeye and chum salmon from Curry Station (RM 120) (Section 2.1). During these surveys the sighting date, tag number, species location in the slough, and behavior of each tagged fish was recorded. Behavior was defined in terms of milling and spawning (Barrett et al, 1984). The Susitna River main channel and side channels in the middle reach were surveyed for salmon spawning by he 1 i copter from August 27 to October 13 near weekly. The criteria previously presented in Section 2.2.1 was used in determining whether a main channel or side channel site was used for spawning. In the middle Susitna River reach, tag recovery surveys were conducted in conjunction with the routine slough and stream spawning ground surveys with the numbers by species of live tagged and untagged fish being recorded. These surveys along with the others addressed in this section were performed by trained observers wearing polarized glasses and using hand-he :d tally counters. Egg retention sampling of sockeye and chum salmon carcasses was conducted in most sloughs in the middle Susitna River reach concurrent with the 1984 escapement surveys. The sample size was based on -12- J I I I I I I I I I I I I I I I I I I I I I I I I I available fish and time. The abdomen of each fish samples was incisioned and the retained eggs, if any, were counted by hand. 2.3 Data Analysis 2.3.1 Salmon Escapement Monitoring by SSS Counter The SSS counters operated at Yentna Station (TRM 04) in 1984 each had a design counting range of 60 feet which was divided into 12 equal sectors. The sonar electronics registered individual sector counts hourly on a printer. The printer tapes were edited in the field and rechecked in the office for debris counts. This editing procedure and the methodology for interpolating for lost sector count$ can be found in Barrett et al, (1984). The daily fish registered echoes by each SSS counter at Yentna Station (TRM 04) were apportioned based on the percent species catch by the fishwheel operating on the same day off the same bank. In instances when the daily fishwheel catch was less than 150 fish the SSS counts were apport1oned according to the cumulative fishwheel catch for the succeeding number of days required to reach a 150 fish threshold catch sample. 2.3.2 Salmon Tag and Recapture Estimates The 1984 salmon escapements to Flathorn (RM 22), Sunshine (RM 80), Talkeetna (RM 103) and Curry (RM 120) stations were quantified in this -13- report using a modified Petersen model by Ricker {1975). The except ion was for chinook salmon measuring less than 351 11111 FL (jacks). The procedure for calculating the jack chinook salmon escapemen ~s along with a discussion of the assumptions and su;tability of the Petersen model, and method used to determine the associated confidence 1 imi ts can be found in Barrett et al, {1984). 2.3.3 Escapement Timing The 1984 sal~n escap~nt timings have been calculated in thi s report for each species by station based on fishwheel catches. A species migration at a sampling station was defined to have 'started', ' reached a midpoint' and 'er1ed' on the date when 5 percent, 50 percent and 95 percent respecti vel y, of the season cumulative, mean hourly, station fishwheel Cdtch by species was reached. Escapement timings by salmon species have also been graphically presented in this report using fishwheel catch per unit effort curves. These curves were smoothed by the von Hann 11 near fi 1 ter method { BMDP , 1981). 2.3.4 Aging Escapement Samples Standard scale analysis techniques were followed in deter.ining the ages of the 1984 salmon escapements (Clutter and White s el, 1956}. all sa lmo n ages have been described in this report using the Gilber-Rich notati on {Barrett et al, 1984). -14- I I I I I I I I I I .. I I I I I I I I I 2.3.5 ~ough Escapements Respective 1984 sockeye and chum salmon escapements to individual sloughs above RM 98 .6 have been calculated by developing a spawner abundance curve from a series of live fish counts ·throughout the spawning season and then determining escapement from the area un1er the curve on the basis of average fish observation life (Cousens et al, 1982). There were two exceptions to this method which 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 have been detennined by adjusting the peak or single escapement count by a factor derived by dividing the sum of the estiMated individual slough escapements above RM 98.6 having peak counts of 50 or more fish by the sum of tile peak counts from these sloughs (Barrett et al, 1984) • Pink salmon escapements to sloughs above RM 98.6 in 1984 have been detennined by adjusting the peak live and dead survey counts by a factor of 1.15. This was derived fr·om the average of an expected 80 to 90 percent of the spawning population being present at the peak escapement count (Cousens et at, 1982). 2.3.6 Estimating Total Susitna Ri ver Chinook Salmon Escapements Annual chinook salmon escapements to the Susitna River drainage for 1982 thr·ough 1984 were calculated by the following formula: -15- where: " NT = Total Susitna River chinook salmon escapement. s1 = Number of chinook salmon counted in index streams below RM 80. s2 = Number of chinook salmon counted in index streams above RM 80 . " NRM80 = Chinook salmon escapement .estimate for. RM 80 by the Petersen method. m • Estimated percent of the RM 80 chinook salmon escapement estimate that reached RM 80 but spawned below RM 80 . Several assum ptions were made in computing the 1982, 1983 and .1984 chinook salmon escapements to the Susitna River system . They were: 1. The ratios of the number of chi nook salmon not counted to the number of chinook salmon cour~ted above and below RM 80 were nearly identical within each year (1982-84). 2. Survey effort, conditions and timing (of index streams) were similar above and below RM 80 within ea ch year (1982-84). 3. Twen~y percent of the estimated escapements to RM 80(Sunshine Station) in 1982, 1983 and 1984 were milling fish. -16- I I I I I I I I I I I I I I I I I I 3.0 RESULTS AND DISCUSSION 3.1 Pacific Salmon ~-· ... ~ ...... ..4-J The Susitna River is the single largest producer of Pacific salmon in Cook Inlet (ADF&G. 1982}. Annually five species return to the system through Cook Inlet where except for chinook salmon, they are subject to an intensive, commercial fishery by set and drift net fishermen. In the S•tsitna River the five spe ci es are subject to harvest by sport fishermen (Mills, 1983). However. the main emphasis is on chinook and coho salmon. Minimum Susitna River salmon escapements not including chinook salmon have been reported for the last three years at: 678,000 fish (1981}. 1,693.800 fish (1982) and 577,800 fish (1983) (Barrett et al, 1984). These estimates only reflect the esc~pements of sockeye, pink, chum and coho salmon to the Yentna River (RM 28) and RM 80. In 1984 the Susi tna River supported a mi nimum escapement of around 5.5 million Pacific salmon based on Petersen population estimates of sockeye, pink, chum and coho salmon escapements for RM 22 and an estimate of the total Susitna River chinook salmon escapement through a Petersen population estimate for RM 80 (Table 3) and selected spawning ground surveys. The composition of this estimate is : 4.6 percent chinook salmon, 11.0 percent !iOCkeye salmon~ 66.1 percent pink salmon, 14.8 percent chum salmon and 3.5 percent coho salmon . The following subsections of th1s report wi l l focus on the 1984 salmon migrations at five locati~ns on the Susitna and Yentna rivers mai nstems (Figure 1), and define where spawning occurred emphasizing the Susitna -17- Table 3.

River from the Yentna River (RM 28) to upper Devil Canyon (RM 161.0). 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 reach division is: lower reach [Intertidal (RM 0.0) to Chulitna River confluence (RM 98.6)] and middle reach ~Chulitna River confluence to upper Devil Canyon (RM 161.0)]. 3.1.1 Chinook Salmon In the last 10 years chinook salmon returning to the Susitna River have not been a target species in the commercial fishery of Upper Cook Inlet. This is due to the early nature of the migrational timing of this species relative to the annual opening date of the fishery (ADF&G, 1982). However, there is a freshwater sport fishery on Susitna River chinook sa lmon. The annual harvest for 1981-1983 has averaged 7,800 f i sh (pers. conrn, K. Delaney). The sport take is principally from -18- l I I I I I I I I I I I I I I I I I I I I I I I I I tributary spawning stocks in the lower river reach. In the Susitn1 River drainage there are about 60 chinook salmon spawning populations (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 al, 1984). The Sport Fish Division of ADF&G has estimated the lasi: two years uf Susitna River chinook salmon ~scapements to be 82,800 fish (1982) and 91,800 f i i h (1983). Th ~s e esti mates were determined by expa11ding surv•!Y counts of selected spawning grounds (pers. comm, K. Delaney). The 1932 and 1983 escapements to the mainstem Susitna River for RM 80 only we~ an estimated 52,900 fish (1982) and 90,100 fish (1983 ) by the Peters•m method (Barrett et al, 1984). This year (1984) chinook salmon escapements into the Susitna River wet~ monitored by ADF&G, Su Hydro staff at Sunshine St3tion (RM 80) in the lower reach and at Talkeetna (RM 103) and Curry (RM 120) stations in the mi dd 1 e reach. The respective escapements detenni ned by the Peterse 1 method are provided in F;gure 2 and Table 4. The total escapement intu the Susitna River basin for 1984 was in the range of 250,0UO f ish. This estimate is base~ on se 1 ected spawning grL,ull..:: surveys and the Petersen escapement est ~mate for Sunshine Station (Section 2.3.6). The following subsections address chinook salmon escapement monitoring i n the Susitna River dr a ina ge for 1984 by river reach. An ex ception is the section covering the chinook salmon inde ~ surveys whicn were conducted drainage wide to measure rel ative escapement. -19- Table 4.

Yentna stations are listed in Appendix Tables 2-3 and 2-6. Ch i nook salmon apportioned SSS counts for Yentna Station are in Appendix Tables 3-1 and 3-2. An estimated 121,700 chinook salmon reached Sunshine Station (RM 80) in 1984 (Tables 4 and 5). Less than four percent of these fish were jack salmon measuring 350 mm or smaller Fl (Table 5) and the remainder (96.2%) were chinook salmon over 350 mm FL. The estimate of 117,100 fish larger than 350 mm Fl was calculated by the Petersen method -21 - {Section 2.2.1). The jack salmon portion of the esti mate was calculated based on the ratio of jacks to adults ( > 350 nn Fl) determined by a length sample from the fishwheels. Table 5. Escapement of chinook salmon 350 mm or less in length in 1984 at Sunshine, Talkeetna and Curry stations. Chinook Salmon Escapement ~ 350 mm Sunshine Station Talkeetna Station Curry Station 4,596 253 639 At Sunshine Station (RM 80) the fishwheels i ntercepted 7,550 chinook salmon in 1984 (Table 6). Based on these catches, chinook salmon were abundant in the Sus1tna River mainstem at RM 80 for 27 days in 1984. The migration began on June 9, reached a midpoint on June 21 and ended on July 6 (Appendix Table 2-11). The chinook salmon migration at RM 80 began and ended about four days earlier on the west side than the east side based on east and west bank fishwheel catches. At Sunshine Station (RM 80) the two east bank · wheels caught approximately 73 percent (5,520 fish) of the 7,550 fish intercepted at RM 80 and the two west bank wheels caught the remaining 27 percent (2,030 fish). Tag recove~ surveys above RM 80 indicated the east bank fistntheels at RM 80 were slightly less efficient than the west bank wheels (Appendix Table 6-4).

The average chinook salmon length (FL) at Sunshine Station in 1984 was 763 mm (Appendix Figure 5-1). Male fish averaged about 15 em smaller l ength tha n the fema l es due to a higher percentage of males in the younger age classes (3, 4 and 5 year olds). Overall males were slightly more abundant in the escapement sample than females at a ratio -30- I I J I I I I I I I I I I I I I I I I I I I I I I I I I of 1.1 :1. Males were more abundant than females ;~ng the three, four and five year old age classes by a ratio of 4. 3: ·.• Females were more nu~~~erous than males in the six and seven year old age classes by a male to female ratio of 0.6:1. 3.1.1.1.2 Spawning Ground Surveys 3 .1.1.1.2.1 Mainstem In 1984 field crews surveyed the Susitna River uainstes fro~~ RM 28 to 98.6 by helicopter and waterbourne craft about weekly and found no evidence that the lower Susitna River mainstem strved as chinook salmon spawning habitat (Appendix 7). These surveys we~! performed from August 21 through October 17. 1984 which is well after the peak spawning occurred in local streams . Fish tagging crews i n the course of their duties at Flathorn (RM 22), Yentna (TRM 04) and Sunshine (RM 80) stations i n June, July and early August also looked for visual evidence of chinook salmon spawning such as repeated surf.tc1ng of ripe fish and carcasses on gravel bars and shoals not related t o washouts from known spawning streams. They also found no evidence of chinook salmon spawning in the mainstem. 3.1.1.1.2.2 Streams and Sloughs Associated stream confluences and sloughs were !urveyed for chinook salmon presence between July 21 and October 21, 19~4. The results are presented it. Appendix 7. -31- 3.1.1.2 Midd l e Reach 3.1.1.2.1. Mainstem Escapement Monitoring In 1984 the chinook salmon escapemt.nt to the ·iddle Susitna River reach was an estimated 24,800 fish at Talkeetna Station (RM 103) and 18,000 f ish at Curry Stat ion (RM 120) (Tables 4 and 5). About 45 percent and 24 percer.t respectively of the escapements reachin~ these stations were mi 11 i ng f i sh that dropped back downstream and spawned . These percentages were determined by spawning ground counts conducted above the tw o stations (Section 3 .1 .1.2.2.2). Most of the chinook salmon that strayed to Talkeetna and Curry stations were destined to spawn in the Talkeetna and Chulitna river systems (Appendix Table 6-4). About one percent of the chi nook salmon escapement reaching Ta 1 keetna Station (~ 103) was jacks (~ 350 mm) (Table 5). At Curry Stati on (RM 120) 3.6 percent of the escapement was jacks. Due to Mgher inshore water velocities at Curry Station than at Talkeetna Station and preference of adult chinook salmon for high water velocities it would have been expected that more jack salmon would have been caught at Talkeetna Station and consequently, would have represented a hi gher fraction of the estima ted escapement. This was not the case. One possibility for the variation is the d ifference in stocks migrating to Talkeetna and Curry stations. As previously repor ted higher numbers of milling fish from Chulitna and Talkeetna rivers reached Ta lkeetna Station than at Curry Stati on. A lower jack salmon concentration i n these stocks would account for the reported variability between Talkeetna and Curry stations. -32- "1 I I I I I I I I I I I I I I I I I I I I I I I I I The migration timings of the 1984 ch i nook escapements to Talkeetna (RM 103) and Curry (RM 120) stations have been determined by analysis of the fishwheel catches at these stations (Appendix Tables 2-14 and 2-17). At Talkeetna Station chinook salmon were abundant i n the mainstem for 26 days and at Curry Station for 24 days . At Talkeetna Station the migration began on June 16 and ended on July 12. The midpoint occurred on June 26. Chinook salmon traveling along the east and west banks of the Susitna River at Talkeetna Station had approximately the same migration timing. The chinook salmon migration at Curry Station began on June 19, reached a midpoint on June 25 and ended on July 13. Also based on fishwheel catches there was no differential timing between chinook salmon traveling off the east and west banks at Curry Station. A plot of daily fishwheel catches at Talkeetna (RM 103) and Curry (RH 120) stations as provided in !Figure 7 indicate there was a surge in chinook salmon numbers at these stations around June 19, 1984. The increase in fish numbers can be attributed to a flow change in the Susitr.a 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 and by June 19 the flow was down around 33,600 cfs (Figure 8}. Fishwheel catches at Talkeetna and Curry stations were relatively weak during the high flow event in the order of 0.4 fish per wheel hour whereas when the flow returned to a near pre-flood level, catc hes excellerated to an average 1.6 fish per wheel hour. Other than the mentioned flow change there were no other known events that could explain the dramatic change in catch levels svch as an alteration in commercial or sport fishing effort. -33- 3 e .JUNE /------------ / I It JULY TALKEETNA STATION East 8ank ----- West 8ank ----- Smoothed by a+2 b+c 4 Curnulative % - - - • Z2 AUG SEP / / ......---------------- I I (' I ' r · .. ~ I I I 1 I CURRY STATION East Bonk----- West Bank--------- Smoothed by a ... 2b +c 4 Cumulative ~.---- tee 89 89 <49 ~ 0 :J E :J u ~ Q) > ...... 0 J E J u ,y I " .JUNE Figure 7.

In 1984 at Talkeetna Station (RM 103) chinook salmon were about 14 percent more abundant along the east side of the Susitna River than along the west side at RM 103 based on f i shwheel dat~ (Appendix Tables 2-12 and 2-14). The tocal station' catch was 3,407 ch i nook salmon (Table 6). Abou t 57 percent of the catch was taken off the east bank and the remaining 43 percent was taken along the west bank . Upstream at Curry Station (RM 120) approximately ten percent more chinook salmon migrated t off the east bank than off the west bank . The east bank wheel accounted for 56 percent and the we st bank whee l caught the remaining 46 percent of the total station catch of 1,589 chinook salmon (Appendix Tables 2-15 and 2-1 6). -35- The 1984 migrational r ates of tagged chinook salmon in the Sus i tna Riv er mainstem between Sunshine (RM 80 ), Talkeetna (RM 103) and Curry (RM 120 ) stations are presented in Append ix 2 and sunnarized i n Figure 9. Generally, chinook salmon covered the 23 miles from Su nshine to Talkeetna stations i n seven to ni ne da ys, the 40 miles from Sunshine to Curry stati ons in 11 to 13 days and the 17 miles between Talkeetna and Curry stations in four to six days . The r~~pective migration speeds were 3.3 mpd, 3.6 mpd and 4.3 mpd derived from the median travel numbers given in Figure 9. Based on these migration speeds, chinoo k salmon migrated slower and/or milled more i n the r i ver reach between Sunshine and Talkeetna stations than between Talkeetna and Curry stations. Figure 9.

The 1984 escapement at Talkeetna Station was comprised of three to seven year old fish (Table 8). The six year o 1 d fish from the 1978 parent year were dominate ( 47. 7!:) followed by the seven year old fish (28.5!:) f ;om the 1977 parent year escapement. Least abundant were three year old fish (l.U:) produced from the 1981 spawning year. The average chinook salmon length (FL) at Talkeetna Station in 1984 was 816 mm (Appendix Figure 5-2}. The average male was about 90 mm smaller than the average female. Overall, male and female chinook salmon were equally abundant (1.0:1) at Talkeetna Station (Table 9). However, mal'!s were more abundant than females among the younger age group (3-5 year olds) by a ratio of 5.5:1 and females were more abundant in the older age group (6-7 year olds) by a male ·to female ratio of 0. 7:1. At Curry Station (RM 120) in 1984, the chinook salmon escapement was comprised of three to seven year old fish (Table 8). Six year old fish from the 1978 parent year were dominate (40.6~) followed by seven year old fish (29.5S) from the 1977 broad year. Least abundant were four year olds (6 .0S) from the 1980 spawning year. The average t.itiuook salmon length (FL) at Curry Station in 1984 was 801 mm (Appendix Figure 5-3). The average female 1 ength was about 140 mm 1 onger than the average male length (Appendix Figure 5-30). In the younger age groups (3-5 year olds) there were more males than females by a ratio of 27.0:1 In the older age groups (6-7 year olds) there were more females than males by a male to female ratio of 0. 7:1. For all age samples the overall male to female ratio was 1 .2:1 (Table 9). _.,.,_ 3.1.1.2.2 Spawninq Ground Surveys 3.1.1.2.2.1 Mainstem In 1984, field crews visually surveyed the Susitna River r.1iddle reach and found no evidence of chinook salmon spawning in the !ilainstem. A number of 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. 3.1.1.2.2.2 Sloughs and Streams Thirty six sloughs and 25 streams in the middle reach were repeatedly surveyed for salmon spawning between late July and mid October, 1984. Also, seven streams above RM 161.0 were surveyed between late July and mid August for chinook salmon. Survey results indicate that chinook salmon did not use middle Susitna River reach sloughs for spawning or milling in 1984 (Appendix 6). Chinook salmon were however, found in 12 streams above RM 98.6 (Table 10). The peak recorded counts totalled 7,180 chinook salmon. The major concentration {96.2%) was found in Indian River (RM 138 .6} and Portage Creek (RM 148.9) (Figure 10}. Fourth of July Creek (RM 131.1\ and Whiskers Creek ( RM 101.4) accounted for 1. 3 percent and ". ~ percent respectively of the total peak count. The eight other streams together contributed 1.6 percent. -38- I I I I I I I I I I I I I I I I I I .

At Indian River the first mile reach is important not only as a migrational corridor for chinook salmon but as a spawning area . It can also be determined from the information pres,,ted in Figures 11 and 12 that helicopter and foot surveys of these streams provide similar results . Chinook salmon spawning in streams above RM 98.6 extended from mid July to mid August (Appendix 6}. The peak spawning occurred in the last week of July. -42- I I I I I I I I I I I I I I I I I I I The minimum number of chinook salmon that spawned in the middle Susitna River reach was 13,800 fish. This estimate was determined by increasing the tota 1, pea k stream escapement count of 7,180 by a factor of 1. 92 based on work by Neilsen and Green (1981) that indicated a peak spawning count represents less than 52 percent of a spawning population. By the same method, the spawning escapements above Talkeetna Station (RM 103) was at least 13,660 fish and above Curry Station (RM 120), 13,610 fish. Based on these estimates 45 and 24 percents respectively of the chinook. salmon that reached Tallc.eetna and Curry stations in 1984 were mil 1 i ng fish that spawned below these stations. Conversely about 55 percent of the escapement that reached Tal keetna Station in 1984 migrated above RM 103 to spawn and about 76 percent of the escapement reaching Curry Station i n 1984 spawned above RM 120. 3.1.1.3 Escapement Index Surveys Based on a survey of 16 index streams, the 1984 chi nook salmon escapement to the Susitna River basin was about 25 percent higher than the previous eight year average and 20 percent higher than the 1983 esc3oement (Figure 13 and Tables 11 and 12}. Most of the streams surveyed (10 out of 16) in 1984 supported higher chinook salmon escapements than in any previous year between 1976 and 1983. All major subreaches of the Susitna River basin with exception of the west reach side below Talkeetna (RM 97.1) which includes the Yentna River system (RM 28) experienced above average escapements in 1984.

West side streams below Talkeetna in 1984 had a 15 percent lower escapement count than the average for 1976 to 1983 and a 15 percent lower escapement count than in 1983. Index streams of the Ch ulitna River s ubdrainage (RM 98.6) had a 95 percent higher fish count in 1984 than the prev i ous eight year average an d a 10 percent higher count than in 1983. In the Talkeetna River subdrainage (RM 97 .1) the 1984 escapement count was 95 percent higher than the 1976 to 1983 average and 160 percent higher than in 1983. The middle Susitna River reach above Talkeetna had a 350 percent higher escapement co unt than the previous eight year average and a 60 percent higher escapement count than in 1983. Annually performed chinook salmon escapement counts of i .ndex streams do not provide an absolute r ~asure of between year escapement differences. In general the index stream counts are a 'hit or miss' proposition attributable in part to factors of weather, inadequate funding and personal restraints. Commonly, poor weather and temporary high discharges occur in the Susitna Ri ver basin between mid July and early August. Such conditions often cause survey delays of a week or more resulting in the peak spawning period to be missed or the surveys being perfonned under poor observation conditions. In recent years nearl y one-third of the index streams have not been surveyed mainly because of inadequate allocation of funding for air charter. Another program deficiency is observer time . Most of the surveys are conducted by staff responsible for other duties coinciding with the timing of chinook salmon spawning. Schedule confli c ts often occur which result in missed -47- surveys, surveys being cond ucted at less than desirable weather conditions and repetitive counts not being made to document between year variation of spawn i ng duration and timing. It is best to consider the 1984 chinook salmon index survey program and previous year programs a general, non-quantitative perspective of between year escapement variability. From this perspective it can be determined that the 1984 chinook salmon escapement for the Susitna River basin, based on index stream surveys, fell well within or slightly above the escapement average for the last eight years. -48- l I I I I I I I I I I I I I I I I I I I I I I I I I 3.1.2 Sockeye Salmon The Susitna River supports two runs of sockeye salmon . The first run is sma ller than the second run and unlike the second run is not subject to a commercial fishery . The first run probably is in the range of 5 to 10 thousand fish based on three years of escapement monitoring at Sunshine Station (RM 80) (Barrett et al, 1984) and an unpublished sighting of suspected first run sockeye in Fish lake Creek off the Yentna River (RM 28) by Barrett in 1973. The seco nd run of sockeye salmon is substantially larger being comprised of over 40 separate populations . Second run stocks are harvested by drift and set net fishermen in Upper Cook Inlet. The commercial contribution of Susitna River stocks is in the range of 10 to 30 percent (Barrett et al, 1984). Susitna River, second run sockeye salmon escapements have never been completely quantified. However minimum annual escapements of 175,900 to 272,900 second run fish have been reported for years 1981 to 1983. These estimates were determined by escapement monitoring to the Yentna Ri ver and at RM 80 (Barrett et al, 1984). In 1984 the minimum escapement was an estimated 605,800 fish based on a first year, tag and recapture operation at RM 22 (S ection 3.1.2.2). Presented in the following subsections are the results of sampling 1984 first and second run sockeye salmon escapements in the lower and middle river reache : of the Susitna River drainage. 3.1.2.1 First Run In the Susitna Riv e r drainage one confirmed and another s uspected stock -49- of first run sockeye salmon passes through the lower river reach annually between late May and mid June. The confirmed stock migrates past Sunshine Station (RM 80) and s pawns in the Talkeetna River drainage in the Papa Bear lake system (Figure 14). The s us pected, second stock utilizes the Fi sh Lake Creek system off the Yentna River (unp ubli shed report, Barrett 19 73) (Figure 15). With exception of a few milling fish, first run sockeye salmon do not penetrate or spaw n i n the middle reach of the Susitna River (Barrett et al, 1984). 3.1.2.1.1 lower Reach 3.1.2.1.1.1 Ma in Channel Escapement Monitoring In 1984, Yentna Station (TRM 04) on the Yentna River was not ~perational early enough to monitor fi rst run escapE!n'ent. Sunshi ne Station (RM 80) was operational on June 4 in time to monitor the escapement into the Talkeetna River system. Based on the Petersen method the 1984 esca pement at Sunsh ine Station as about 4,800 fis h (Ta ble 13).

Suspected destination of first run sockeye salmon into the Yentna Ri\er dra i nage, 1984. -51- The four fishwheels at Sunshine Station (RM 80) caught 500 first run sockeye salmon in 1984 (Table 13). Based on an analysis of the catch the migration began on June 4, reached a midpoint on June 10 and was over by June 22 (Appendix Table 2-11). The peak migration occurred on June 9 with an average catch per fishwheel hour on this date of 0.6 fish. The two east" bank fishwheels at Sunshine Station (RM 80) caught 98.8 percent of the station catch of first run sockeye salmon in 1984. The west bank wheels intercepted the remaining 1.2 percent. From this it is apparent that first run fish near exclusively used the east side of the Susitna River at RH 80 for migration in 1984. First run sockeye salmon were sampled at the fish~.,h eels at Sunshine Station (RM 80) to determine representative escapement age, length (Fl) and sex composition (Table 14). Nearly the entire 1984 escapement (96.5%) was five year old fish from the 1979 brood year (Table 15). The remainder of the escapement (3.6%) included four and six year old fish. Nearly alJ the returning first run sockeye salmon in 1984 had spent one winter in freshwater before entering the marine environment. The average length (Fll of a first run sock.eye salmon in 1984 was 532 111n (Appendix Figure 5-6). The males averaged about 36 mm longer than the females. The male to female ratio in the escapement was 0.5:1 (Table 16). Female fish were more abundant than males in all age classes (4-6 year olds). -52- -------------------Table 14.

The peak of spa wning occurred around July 20. These findings are based on two escapeme nt surveys conducted on July 14 and 26 (Table 17). On the f i rst survey there were about 1,500 sockeye i n Papa Bear Inlet stream that were just beginning to spawn and another 500 to 1,000 fish hold i ng off the creek mouth in Papa Bear Lake .

Approximately 500-1,000 sockeye salmon milling at the lake inl et. July 26, most of the fish in the creek were in post-spawning condition, and there were no sockeye salmon observed off the stream, mouth. The results of 1984 tag recovery surveys covering first run sockeye salmon are listed in Table 17 . About 8.5 percent of the 1,536 fish observed on the July 14 survey of Papa Bear Lake inlet stream were tagged compared to 16 .7 percent of the 432 fish counted on the last survey (July 26). These figures indicate that the first run migration at RM 80 began a few days before tagging operations started or that the fishwheels at Sunshine Station {RM 80) were more efficient at the end of the migration than at the beginning . Review of the daily fishwheel catches at Sunshine Station supports the conclusion that some first run sockeye salmon passed Sunshine Station prior to the beginning of site operations on June 4. Inasmuch as the first run escapement spawned over a relatively short time period (three weeks) and the two escapement surveys were random, the Petersen method is still appropriate for -57- calculating the escapement even though some early migrating fish were not intercepted. 3.1.2.2 Second Run 3.1.2.2.1 Lower Reach 3.1.2.2.1.1 Main Channel Escapement Monitoring In 1984, second · run sockeye salmon escapements were monitored at three locations in the lower river reach .

However, no spawning surveys were performed below RM 22, and therefore it is not possible to quantify the level of milling. The estimated escapement of 605,800 fish for Flathorn Station should be considered the number of fish that reached this location and not the number of fish which necessarily spawned upstream of this location. In the Yentna River (RM 28) at Yentna Station (TRM 04) the 1984 escapement wa s approximately 149,400 fish determined by SSS counters (Table 19). This represents about 25 percent of the estimated escapement to Flathorn Station (RM 22). At Sunshine Station (RM 80) farther upstream in the lower river reach an estimated 130,100 second run sockeye salmon reached this location as calculated by the P~tersen method (Table 18). This escapement estimate represents about 21 perce11t of the reported escapement to Flathorn Station. Base · on the estimated escapement of Flathorn, Yentna and Sunshine stations about 300,000 sockeye salmon spawned in areas of the Susitna River basin other than in the Yentna River drainage and above RM 80. The four known sockeye salmon spawning systems below RM 80 excluding the Yentna River are defined in Figure 17. Of these the Fish Creek drainage (PM 8) is probably the most productive based on historic surveys (ADF&G, 1982). The Alexander (RM 10 ) and Deshka (RM 40) rivers and Whitsol lake drainages are minor sockeye salmon systems (per. comm, K. Delaney). -60- I I I I I I I I I I I I I I I I I • I I I 1 I I I Figure 17.

At Flathorn Station (RM 22) the migration covered approximately a three week period from July 16 to August 9. The midpoint of the migration in the east channel occurred on July 22 and one day earlier in the west channel on July 21 . Overall, there was no appreciable difference in the escapement timing between east and west channel migrating stocks at RM 22. About 10 mi lE·s upstream at Yentna Station (TRM 04) the second run escapement migration began on July 17, reached a midpoint on July 22 and ended on August 8. These dates are one day later than the comparable dates for fish migrating in the west channel past Flathorn Station (Figure 18). At Sunshine Station (RM 80) the sockeye migration covered 16 days from Jul y 20 through August 5. The migration midpoint occurred on July 24 just f~ur days after the start (Figure 19). In 1984, sockeye salmon tagged at Fl athorn Station (RM 22} were recaptured at upriver sampling stations on the mainstems of the Yentna and Susitna rivers. The results are presented in Appendix 4 and summarized in Figure 20 .

Density independent factors effecting fishwheel catches include nearshore velocities, channel configuration, bank slope and bed material. Catch difference between station fishwneeis ca~ indicate fish migration preferences. At Flathorn Station (RM 22) sockeye salmon slightl y -65- ,, favored the west channel over the eas ~ channel for migration based on 54.8 percent of the station catch made by west channe l fishwheels and 45 .2 percent by the east channel fishwheels {Appendix Tables 2-1 and 2-2). In the west channel, sockeye salmon were more abundant along the left bank than the right bank. The left and right bank whnels caught 59.9 percent and 40.1 percent of the catch respectively. In the east channel at Flathorn Station, most of the fish passed along the left bank . The 1 eft bank fi shwhee 1 caught 69.9 percent and the right bank fishwheel caught the remaining 30.1 percent . On the Yentna River (RM 28) at Yentna Station {TRM 04) sockeye salmon favoretf the south bank over the north bank for migration. The south bank fishwheel caught 91.5 percent of the station catch and the north bank fishwheel made 8.5 percent of the catch. The same migration trend was observed with the SSS counters at Yentna Station . About 95 percent of the apportioned sockeye salmon counts were logged by the south bank counter. At Sunshine Station (RM 80) most of the sockeye migrated along the east bank. The two east bank fishwheels caught 76.5 percent of the station catch and the remaining 23.5 ~ercent were taken in the two west bank fishwheels. In 1984, tag numbered sockeye salmon released in the east and west channels of Flathorn Station (RM 22) were recaptured at Yentna Station (TRM 04), and Sunshine (RM 80), Talkeetna {RM 103) and Curry (RM 120) stations (Figure 21 and Table 20).

Sockeye salmon extending to RM 80 and above also preferred the east channel at Flathorn Station. About 96 percent of the tag numbered recaptures were re 1 eases form the east channel fishwheels compared to about four percent from the west channel wheels. Around 90 percent of the sockeye salmon which did not either enter the Yentna River or migrate to RM 80 reached Flathorn Station via the west channel. Most of these fish may have been destined to the Flathorn Lake drainage as previously discussed . Representative age, length and sex samples were collected from the 1984 sockeye salmon escapements to Flathorn (RM 22), Yentna (TRM 04) and Sunshine (RM 80) stations. Most of the 1984 escapement in the lower river there were four and five year old fish from the 1980 and 1979 parent years, respectively (Figure 22). The escapement at Flathorn Station and about the same level of four year old fish as five year olds. At Yentna Station, five year old fish were more abundant than the four year olds, but at Sunshine Station four year old fish were nearly twice as numerous as five year olds. At all the stations, most of the escapement were returning fish that 1 eft freshwater to commence ocean rearing in their second year of life.

Specific results are presented in Appendix 7 . 3.1.2.2.2 Middle Reach 3.1.2.2.2.1 Main Channel Escapement Mon i toring Second run sockeye salmon escapements were monitored in the middle river reach at Talkeetna (RM 103) and Curry (RM 120) stati ons in 1984 . The estimated escapements to these locations were 13,100 fish and 3,600 fish, respectively (Table 18). The confidence limits associated with these estimates are in Tab ~e 18 . Most (83~) of the sockeye salmon escapement reaching Talkeetna Station (RM 103) were milling fish that spawned in the lower Susftna Ri ver reach . ~bout 17 percent of the escapement reaching Talkeetna Station spawned in the middle river reach. At Curry Station (RM 120) around 38 percent of the escapement were milling fish and 62 percent were fish which spawned in the middle river reach . The bases for these estimates are in report section 3.1.2.2.2.2. -70- I I I I I I I I I I I I I I I I I I I In 1984, second run sockeye salmon migrated in the middle mainstem reach of the Susitna River over a three to five week period as determined by fishwheel catches at Talkeetna (RM 103) and Curry (RM 120) stations (Appendix Tables 2-14 and 2-17). At RM 103, the migration began on July 22, reached a midpoint on July 28 and ended on August 12. Seventeen miles upstream at RM 120, the sockeye salmon migration lasted about 13 · days longer. The onset began on July 22, midpoint was on August 1 and the end occurred on August 25. The 1984 migrational rates of tagged sockeye . salmon recovered · ·in the lower and middle Susitna River reaches are presented in Appendix 4 and summarized in Figure 20. The data indicate that tagged fish generally traveled between Sunshine (RM 80) and Talkeetna (RM 103) stations in about four days and two to five days between Talkeetna and Curry (RM 120) stations. Overall, the migration between Sunshine and Curry. stations genf':rally took six to nine days. From the lowest site in the lower Susitna River, Flathorn Station (RM 22) to the furthest upper middle river site, Curry Station, the 98 miles were normally covered in 14 days for an average net migr'ttion speed of 7 mpd. In 1984 the majority of the sockeye salmon passed along the west bank at Talkeetna Station (RM 103) and the east bank at Curry Station (RM 120) based on reported fishwheel catches (Figure 23). The east and west bank fishwheels at Talkeetna St ~tion respectively caught 44 percent and 56 percent of the stati.on catch (Appendix Tables 2-12 and 2-13). At Curry Station, the east and west bank wheels caught 80 percent and 20 percent of the station catch respectively. -71- 2 Ql 1 .5 Gl ..£. 3 ' L J 0 ::r: ' ..£. en LA.. 0 .s 9 0 .8 Ql 0 .e Gl ..£. 3 ' L J 0 .4 0 ::r: ' £. en lL.

I I I I I I I I I I I I I I I I I I I I I I I I I I Sockeye salmon fishwheel catches at Talkeetna (RM 103) and Curry (RM 120) stations were generally, normally distributed through the migration period (Figure 23). There were two major exceptions and both occurred about the same time at the two stations. They appear to be 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. Thfs coincided with a high water event where flows as measured at Gold Creek rose about 11,400 cfs 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. The fi shwhee 1 catches a 1 so changed at Curry Station about the same time but less dramatically. On July 26, the CPUE was 0.6 and 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. In 1984, ~8 second run sockeye salmon marked with numbered tags at Talkeetna Station (RM 103) were recaptured at Curry Statio, (RM 120). From the information listed in Table 21 it can be determined if sockeye salmon tagged off the different banks at Talkeetna Station exercised differential milling behavior and /or crossover. The data indicated that a high percentage (89%) of the milling fish t~at reached Talkeetna Station traveled along thP. west side of the Susi'tna River at this location. Most of the escapement (86%) that continued on to Curry Station were fish that migrated along the east bank of the river at Talkeetna Station. There was more crossover among west bank migrant fish than east bank fish based on recaptures at Curry Station. About 50 percent of the sockeye salmon that migrated past Talkeetna Station on -73- the west side of the river and continued on to Curry Station remained along the east bank of the Susitna River at Curry Station. By comparison, around 83 percent of the fish migrating along the east side of the S\.lsitna River at Talkeetna Station and continuing on to Curry Station were along the same bank of the Susitna River at Curry Station .

(Figure 20). The average migrational speed between Sunshine and Talkeetna stations was 5.8 mpd and between Talkeetna and Curry stations 8 .5 mpd. The differences in migrational speed may be related to differential milling behavior. As previously reported, sockeye salmon milled less in the area of Curry Station than at Tal keet!'!~ Station. As one would expect, the higher the milling activity the ·ilower the net migration speed. This would explain why fish averaged a s 1 ower trave 1 speed between Sunshine and Ta 1 keetna stations than between Talkeetna and Curry stations . -74- _I I I I I I I I I I I I I I I I I I I I I . I I I I In 1984 a representative age, length and sex comp osit ion sample was co 11 ected from second run sockeye salmon intercepted by fi shwhee 1 s at Talkeetna (RM 103) and Curry (RM 120) ~t~tions. The !dta ind icate the Talkeetna Station escapement was predominantly four (83.8%) and five (14.5$) year old fish (Table 16). About 91.6 percent of four and f i ve year old fish had smolted in their sec.ond year of life following completion of one winter in freshwater as fry. The same trend was apparent at Curry Station. Four year old fish represented 72.7 percent and five year old fish 22 .7 percent of the escapemen t population. About 81.6 percent of the four and five year old fish reachin~ Curry Station had smolted in their second year. Three and six year old sockeye salmon represented 1 ess than five percent of the escapement populations to Talkeetna and Curry stations . The average length (FL) of second run sockeye salmon at Talkeetna Station was 513 11111 and 17 11111 smaller at Curr:1 Station at 496 11111 (Appendix Figures 5-9 and 5-10). Generally among all age classes sampled at Talkeetna Station males averaged about 20 11111 longer length than the females. At Curry Station, the males averaged about 40 mm shorter length . Sex composition data collected indicate males were less numerous at Talkeetna Station than females but more numerous than females at Curry Station (Table 17). The respective male to female ratios were 0.7:1 and 1.4:1. 3.1.2.2.2.2 Spawning Ground Surveys 3.1.2.2.2.£.1 Mainstem In 1984 the Susitna River mainstem middle reach was survP.yed from late July through mid October using helicopter and waterbourne craft for the -75- Map purpose of identifying si1 lmon s pawn i ng areas.

The peak of spawning was around September 15 (Appendix Table 6-1). Four of the seven mainstem sockeye salmon spawning area located in 1984 were in Side Channe l 11 (RM 134.5-135.3). The relatively high sockeye salmon return to Slough 11 (RM 135.3) probably influenced the use of these sites. The highest count of the seven mainstem spawning areas w~s 33 fish. Side Channel 11 accounted for 52 percent. If ~ssumed that the highest count (33 fish) reflects about one -third of the spawn i ng population the mainstem spawning popul~tion in the Susitna River middle reach was probably around 10~ fish. In perspective with the estimated escapements of 13,200 fish to Tr 1keetna Station (RM 103) and 3,200 fish to Curry Station (RM 120) this would be about one percent of the escapement migrating to Ta 1 keetna Station and three percent of the escapement reaching Curry St,:tion . 3.1.2.2 .2.2.2 Streams Thirty-seven s 1 oughs and 25 streams i n the middle river reach were periodically surveyed for salmon spawning form late July to mid October, 1984. The results are listed in Appendix Tables 6-2 and 6-3. Sockeye salmon were observed in only two streams i n the middle river reach in 1984. These were Indian River (RM 138 .6 ) and Portage Creek (RM 148.9). The respective peak counts were 1 and 12 f i sh. Spawning wa s only observed in Portage Creek at its junction with the Susitna River . -77- The sighting was 1 fmited to a pair of sockeye salmon occupyf,ng a redd at the mouth of Portage Creek on September 2. In the range of 25 sockeye salmon occupied stream habitats in the middle Susana River reach 1n 19S4. This is based on an assumption that the total peak count represents about 50 percent of the actual escapement. Based on the number of spawning ground surveys conducted and the relatively minimal number of fish counted, it can be concluded that streams in the Susitna River middle reach are not important for sockeye salmon production. 3.1.2.2.2.2.3 Slaughs .3.1.2.2.2.2.3.1 Observation Life In 19S4, 167 sockeye salmon were released at Curry Station (RM 120) with hrge numbered Petersen disc tags. About 35 percent of these fish entered sloughs SA (RM 125.1) and 11 (RM 135.3) after an average 38 days from being tagged (Figure 25). The majority of the 3S days was probably spent ripening in the Susitna River main channel based on sockeye salmon being capable of sustaining relatively fast travel speeds over long distances. For example, sockeye salmon averaged 7 mpd between Flathorn (RM 22) and Curry stations in 19S4 (Section 3.1.2.2.2.1 ). The distance between Curry Station and sloughs SA and 11 is 5.1 and 15.3 miles respectively which could have easily been traveled in two days if direct migration was intended. There are several possible advantages of sockeye salmon ripening in the -7S- I I I 't I I I I I I I I I I I I I I I I I I I 40 -SLOUGH 8A n • 44 ~ 30 u z ... & i' • 31.2 doya -so • 11 .5 doya ... a: • 10 ~ z , ..... ... u a: ... 10 L 11.7'!1, 10.1'!1. 10.1.., I .., ..

For example, the middle reach sloughs are relatively shallow and non-turbid making predation a greater factor than in the mainstem. Also the sloughs are relatively small in size and may serve as a spawning area for more than one species. Expectedly crowding and associated disease problems would be le!.s in the mainstem than in the sloughs. In drainages where there is a lake associated with a spawning stream or slough, sockeye salmon c0111110nly ripen in the lake before initiating spawning. For example, in the Kasilof River drainage, sockeye salmon spend between three and four weeks ripening in Tustumena Lake rather than in inlet spawning streams and sloughs, which are characteristically similar to middle reach Susitna River sloughs which are shallow, non-turbid, frequented by bears and commonly crowded with spawning fish (AOF&G, 1972). In comparison, Tustumena Lake provides good escape cover and dispersion area for tens of thousands of adult salmon as does the Susitna River. The mean average observation life of so~keye salmon entering sloughs SA (RM 125.1) and 11 (RM 135.3) in 1984 was a.4 days (Figure 26). The average fish observation life between the two sloughs varied by 1.1 days. Variations in observation life tim,.! between individual fish in both sloughs were evident by the relatively large standard deviations. The main cause for the variability was probably milling. Approximately 42 percent ·'af the 131 fish monitored at the two sloughs did not initiate spawning (Table 22). Assumedly many left to other systems although some may have been removed by predators. -80- I I I I I I I I I I I I I I I I I I 10 ,.. 40 ~ "' g "' c ...

Escapement Surveys In 1984, relatively high numbers of spawning sockeye salmon were recorded at sloughs in the Susitna River middle reach (Table 23). Eighteen of the 36 sloughs surveyed (SOl) harbored adult sockeye salmon. -82- J 1 I I I I I I I I I I I I I I I I I I I I I I I I Sockeye salmon spawned in 13 of the 18 sloughs. The three major spawning sloughs were: 11 (RM 135.3), 8A (RM 125.4) and 21 (RM 141.1) in that order of importance (Figure 27). Sloughs 5 (RM 107.6), 8 (RM 113.7), 88 (RM 122.2), 9 (RM 128.3) and 15 (RM 137.2) were not considered spawning areas. Relatively few fish occupied these sloughs and none were observed on redds. The peak survey counts of 1 ive and dead sockeye salmon for the 18 occupied sloughs totaled 926 fish. Sloughs 8A, 11 and 21 supported about 88 percent of the peak counts. Spawning occurred in these sloughs from the fifst week of August through the first week of October. The peak of spawning was between the last week of August and the second week of September (Figure 28). Table 23. Sockeye sa 1 mon peak survey counts of s 1 oughs above RM 98.6 in 1984.

In both fisheries, the majority of the fish harvested are Sus i tna River stocks (ADF&G, 1982 and Mills, 1983). With ·in the Susitna Ri ve r there are a minimum of 40 tributaries providing pink salmon spawning habitat. The major i ty of these are in the l ower river r each below RM 80 (ADF&G, 1982). The mininun Susitna River pink salmon escapements for the last three years have been: 86,000 fish (1981). 891,000 f ish (1982) and 101,000 fish (1983) (Barrett et al, 1984 ). These minimum escapement numbers do not include fish spawning below RM 80 with the exception of the Yentna Ri ver (RM 28). In 1984, the minimum escapement was 3,629,900 f i sh as determined by a first year tagging program a ~ RM 22 (Section 3.1.3.1.1). The following subsections of this report present specific results of sampling the 1984 pi nk salmon escapements i n ~he lower and middle river reache s of the Susitna River. 3.1 .3.1 Lower Reach 3.1 .3.1.1 Main Channel Escapement Mon i to r i ng The escapements of pink salmon in the Susitna River to Flathorn (RM 22) and Sunshine (RM 80) stations were determined by the Petersen tag and recapture method .

In the Yentna River (RM 28) at Yentna Station pink salmon were abundant for about three weeks from July 21 to August 5. The pink salmon migration at TRM 04 reached a midpoint on July 28 . The peak one day fism.heel catch of pink salmon at Flathorn, Yentna and Sunshine stations occurred on July 28, July 25 and July 30, respectively (Figures 31 and 32). Pink salmon migrational characteristi cs were determined from 1984 fishwheel catches at Flathorn (RM 22), Yentna (TRM 04) and Sunshine (RM 80) stations (Figures 31 and 32 and Appendix 2). At Flathorn Station the river was comprised of two channels , east and west . The channels were formed by a large island comple x and f i shwheels were located on the east and west mainland banks and the east and we s t banks of the largest island (Appendix Figure 1-1). Fishwheel catches of pink salmon, adjusted by catch -92- I I I I I I I I I I I I - I I I II rJ II per unit effort, were distributed among the four fishwheels as f ollows: 48.1 percent left east channel (island fishwheel), 28.0 percent right east channel, 17.2 percent right west channel (island fishwheel) and 6.7 percent left west channel . From these values i t is apparent that, given no fishwheel selectivity or stock differentiation, pink salmon migrate predominately in the east channel at RM 22. In the Yentna River at Yentna Station, pink salmon migrated predomin antly along the south bank where 64.1 percent of the fishwheel catch at this station occurred. The majority (63.5 percent) of' the 93,919 pink salmon intercepted at Sunshine Station were captured in east bank fishwheels. A rev i ew of 1984 tag recovery data collected at Yentna (TRM 04) and Sunshine (RM 80) stations indicated that at RM 22, six miles below the Yentna (RM 28) and Susitna rivers confluence, pink salmon stocks are not segregated by river channel (Table 27). Yentna Station fishwheels intercepted 24 pink salmon originally tagged at Flathorn Station (RM 22). Fourteen of the 24 were numbered tags and of those fourteen, 50 percent were tagged on the west channel and 50 percent on the east channel at RM 22. ~t RM 80, 103 and 120, a total of 62 pink salmon marked with Flathorn Station numbered tags were recovered. Twelve and 87 percent. respectively, were originally tagged on the west and east channels at RM 22. These data indicate that Yentna River stocks were evenly distributed between the east and west channels passing RM 22, while the ~~tajority (87r.) of the pink salmon reaching Sunshine Station favored the east channel at RM 22 (Figure 33). These observations were derived from relatively small samples. -93- Table 27.

These data are presented in Appendix 2 and summarized in Figure 34. Pink salmon required about 3 days to travel the 10 mile distance between Flathorn (RM 22) and Yentna (TRM 04) stations. This represents a migrational rate of 3.5 mpd. Pink salmon needed an average of about 7 days to travel the 58 miles between Flathorn and Sunshine (RM 80) stations for a migrational rate of 8.2 mpd . The slower average travel rate between Flathorn and Yentna stations may be due to or a combination of: 1) tagging related stress experienced at RM 22 or 2) milling at the confluence of the Yentna (RM 28) and Susitna rivers.

There were more males than females at Flathorn, Yentna and Sunshine stations as indicated by respective male to female ratios of 1.3:1, 1.2:1 and 1.1:1 (Table 28). 3.1.3.1.2 Spawn i ng Ground Surveys Surveys of the lower Susitna River main channel , s i de channels, slough and stream mouths for adult salmon spawning ac tivity were conducted from Jul y 21 to October 17 in 1984 .

Pink salmon escape.ents to Talkeetna (RM 103) and Curry (RM 120) stations respectively represent 4.9 percent and 3.2 percent of the minimum 1984 Susitna River escapement (F i gure 30). Based on the estimated nu.ber of pink salmon spawning in stream and slough hab i tats above RM 103 approxiute ly 85 and 80 percent of the escapement to Talkeetna and Curry stations, respectively, were milling fish (Section 3 .1.3.2.2.2). Fishwheel catches of pink salmon were used to evaluate migrational timing at Talkeetna (RM 103) and Curry (RM 120) stations in 1984 (Figure 35 and Appendix 2}. Pink salmon were generally abundant at Talkeetna Station for about two weeks fr011 July 25 through August 10. The migration reached a median on August 3. At Curry Station pink salmon were generally abundant for two weeks from July 29 to August 13. The midpoint of the pink salmon migration at this station was August 4 . Peak fishwheel catches occurred on August 3 at Talkeetna Station and on August 5 at Curry Station. Fishwheel catches at Talkeetna (RM 103} and Curry (RM 120} stations indicate that the 1984 pi nk sa l mon escapements to these stations migrated primarily along the west bank assuming that stocks were mi xed and no differential fishwheel selectiv i ty occurred (Figure 35). A total of 29,236 pink salmon were intercepted by Talkeetna Stati on fishwheels, 74 .8 percent of which were captured in west bank fishwheel s (Appendix Tables 2-12 and 2-13).

These data indicate little differential milling between east and west bank pink salmon stocks at RM 103. This is further substantiated by tag recoveries in Lane Creek (RM 113.6), 4th of July Cr eek (RM 131.1) and Indian River (RM 138.6) where a combined 72.8 perce nt of the numbered Talkeetna Station tags recovered from pink salmon carcasses were from fish tagged on the west bank at RM 103 (Table 30).· The pink salmon tar, recovery ratios from Curry Station and the spawning grounds are similar to expected values given mixed stocks and no differential milling at RM 103. The 1984 migrational rates of tagged pink salmon recaptured in the lower and middle Susitna River reaches are presented in Appendix 2 and Figure 34 . Based on these data, pink salmon required an average of about four days to travel between Sunshine (RM 80) and Talkeetna (RM 103) stations and about 2 days between Talkeetna and Curry (RM 120) stations for respective migrational rates of 5.9 mpd and 9.4 mpd. Between Sunshine and Curry stations, pink salmon traveled in about five days which translates into a trav el rate of 7.7 mpd. Pink salmon traveled between Flathorn {RM 22) and Talkeetna stations and Flathorn and Curry stations in about 10 (8.1 mpd) and 11 (8.9 mpd) days. respectively . Length (Fl) data obtained from a subsample of the Talkeetna (RM 103) and Curry (RM 120) stations escapements are presented in Table 28 and Appendix 5. Sample lengths ind icate that the average length of both sexes combined was 447 mm at Talkeetna Station and 441 nwn at Curry -101- .. Station. Male pink salmon averaged 13 mm longer than females at Talkeetna Station and 4 mm longer than females at Curry Station (Table 28). Male pink salmon were more numerous than females at both Talkeetna and Curry stations . The respective male to female ratios were 1.1:1 and 1.6:1 (Table 28). 3.1.3.2.2 Spawn i ng Ground Surveys 3.1.3 .2.2.1 Mainstem The Susitna River main ch ~nnel between RM 98.6 and 161.0 was surveyed on a regular basis f or adult salmon spawning activ i ty i n 1984. Surveys were conducted by boat and helicopter from July 21 through October 14. The survey resul t s are ~resented in Appendi x 6. AOF&G field personnel observed no pink salmon spawners in t l1e Susitna Ri ver main channel , however, an employee of E. Woody Trihey and Associates reported an unquantified number of pink salmon spawning near the east bank at RM 119 .1 (T r ihey, 1984). 3.1.3 .2.2.2 Sloughs and St reams Thirty seven sloughs and 25 streams between RM 98.6 and 161.0 were s ur veyed i n 1984 to determine the pink salmon distribution in this river reach. Surveys were performed near weekly from July 21 unti 1 October 14 . A s ummarization of t he results can be f ound in Append ix Table 6-2 and 6-3. Pink salmon were observed in 17 of the 37 sloughs surveyed .

Sixty three percent of the pink salmon, based on peak survey counts, spawned in sloughs SA, 11 and 20 (Figure 36). Table 31.

I I I I I I I I I I I I I I I I I I I The estimated pink salmon escapement to sloughs in 1984 was 619 fish (Table 32). Pink salmon which spawn in c;loughs represent about one- half of a percent of the escapement reaching Curry Station (RM 120), re-enforcing the premise that pink salmo~ are distributed primarily in stream habitats in this river reach. In 1984, pink salmon were observed in 22 streams in the middle Susitna River reach (Appendix 6). The peak live 3nd dead survey count of all streams totaled 17,505 pink salmon (Table 33). Three streams contributed 77.8 percent to the total; they were: Indian River (RM 138.6) (51.8 percent), Portage Creek (RM 148.9) (15.5 percent), and 4th of Ju 1 y Creek ( Rf4 131. 1) (10. 5 percent). Stream surveys conducted in the middle Susitna River reach consisted of two types, foot and helicopter surveys. Foot surveys were generally conducted over a predetermined reach of a stream, referred to as the index reach. These surveys were not intended to enumerate total stream escapements, rather provide a relativ~ index of abundance for each stream. Helicopter surveys usua 11y encompassed the entire salmon spawning reach of each stream surveyed. He 1 i copter surveys, with adjustments to account for salmon observation life and efficiency of helicopter counts, may be used to estimate the total escapement to a particular stream. Pink salmon distribution within select streams between RM 98.6 and 161.0 was determined by repetitive helicopter surveys in 1984 (Appendix 6). Based on these surveys, the upper limit of migration in the three most productive pink salmon streams, Indian River (RM 138.6), Portage Creek (RM 148.9) and 4th of July Creek (RM 131.1), was about 8.7, 6.8 and 1.9 -105- I ...... 0 0'\ I Table 32.

From this it is rea sonab l e to assume that the r urvey inde x reach of I ndian River provides a major porti on of the spaw ning habitat in this stream whereas the i nd ex area of Portage Creek is uti l ized primarily as a migratory corridor. The 1984 pink salmon escapements to Indian River (RM 138 .6) and Portage T Cre€k (RM 148 .9} can be estimated because the peak survey counts were of ~a ch streams entire spawn i ng range. Co usen s et a l (1982} su11111arize several wor ks indicating that peak livP. plus dead survey co unt s of salmon species with a short spaw ni ng duration . s uch as pink salmon, -109- represent R0-90 percent of the spawning population. Therefore, a factor of 1. 2 was used to adjust peak live and dead survey counts of Indian River and Portage Creek. The peak survey count from Indian River was further adjusted by the ratio of helicopter to foot surveys of the index reach. Th 1 ~ adjustment increased the peak survey count by 47.7 per :ent. This adjustment was not considered a reasonable procedure for Portage Creek where peak surveys of the index reach were four days apart and the fact that this reach i s used primarily as a migratory corridor and not for spawning as in Indian River. Subject cu the above adjustments the estimated escapement to Indian River wa~ about 16,100 f i sh an~ to Portage Creek 3,100 fish. The escapement to Indian River i s based on a "fair" survey coun 4; which was hampered by rain and poor light conditions . Because of the fair survey conditions it is likel y the actual escapement to Indian River was larger than calculated. In 1984 the minimum escapement to all streams and sl oughs above RM 120 was 23,000 fish . This value is reported as mi nimum because peak s urveys in all streams except Indian River (RM 138 .6) and Portage Creek (RM 148 .9) were foot surveys and cannot be expanded to r ep •·esent the es capement of the entire s tream. Based on these data, approximately 80 percent of the pink salmon reaching Curry Sta t i on (RM 120) are milling fish. By extention of this method approxi mately 85 percent of the pin k s al~on rea ch ing Talkeetna Station (RM 103 ) were mill i ng fi s h. Pink s almon sp Jwning in s treams ranged from the f i rst and third wee ks of Augu s t i n 1984 bas ed on l ive and dead survey counts of 4th of Jul y Cree k (RM 131.1), Indian River (RM 138.6) and Portage Cr ee k (RM 148 .9) (Appendi x 6 ). Based on the same data, the pea k of s pawning oc curred during the sec ond and third weeks of Augus t . -110- u I I I I I I I I I ·I I I I I I I I I I I I I I I I 3.1.4 Chum Salmon Chum salmon are a major target species in the combined Upper Cook Inlet drift and set gi 11 net fishery. Host of the connerci a l harvest is Susitna River fish (AOF&G, 1982). The suspected contribution is in the range of 50 JJercent (Barrett et al, 1984). Within the Susitna River system there are a minimum 45 chum salmon spawning populations (AOF&G, 1982). The principle spawning areas are in the Talkeetna River subdrainage (Barrett et al, "1984). The minimum chum salmon escapements to the Susitna River have been reported for the last three years at 282,700 fish (1981), 458,200 fish (1982) and 276,600 fish (1983) (Barrett et al, 1984). These estimates only reflect the escapements to the Yentna River (RH 28) and RH 80 near the George Parks Highway bridge . In 1984, the minimum chum salmon escapement was about 812,700 fish based on a Petersen estimate derived from a first year tagging operation at RH 22 (Section 3.1 .4.1 .1). The following subsections of this report present the results of 1984, chum salmon studies by lower and middle Susitna River reaches. 3.1.4.1 Lower Reach 3.1.4.1.1 Main Channel Escapement Monitoring In 1984, chum salmon escapements were monitored in the lower Susitna River reach at Flathorn (RM 22), Yentna (TRM 04) and Sunshine (RM 80) stations . The estimated 1984 escapements were: 812,700 fish (Flathorn Station), 26 ,500 fish (Yentna Station) and 765,000 fish (Sunshine -111- Station) (Tables 34 and 19 and Figure 39). These -estimates were calculated by the Petersen method with exception that the Yentna Station escapement was determined by SSS counters. The confidence limits associated with the Petersen estimates are in Table 34. Table 34.

For practical purposes the chum salmon escapement estimate to Flathorn Station can be considered an estimate of the entire Susitna River escapement co nsidering the minimal spawning below RM 22. The comparison of the chum salmon escapements for the three lower river monitoring stations in Figure 39 illustrates the distribution of the Susitna River escapement. About 97 percent of the total escapement was to the Yentna River (RM ~8) and RM 80. The Yentna River portion was 2.6 -113- l percent and for RM 80, 94.1 percent. Around three percent of the Susitna River chum esc apement was destine to spawning habitats in the lower reach mainstem and tributaries below RM 80 excluding the Yentna River. Chum salmon catches in the fishwheels operate d at Flathorn (RM 22), Yentna (TRM 04) and Sunshine (RM 80) stati ons totaled 7,519 fish, 1,431 fish and 56,681 fish respect i vely or about 1 percent, 5 percent and 7 percent of the respective estimated 1984 escapements to these stations . These fishwneel catches provide the basis for determining escapement timi ng (Appendix 2 and Figures 40 and 41). At Fl athorn Station chum salmon were abundant in the mainstem for 41 days. The migration began in the ~ast channel at Flathorn Stat ion on J uly 18, reached a midpoint on July 25 and ended on August 25. The respective dates for the west channel were July 18, July 29 and August 28. Upstream 10 miles at Yentna Station in the Yentna River (RM 28) the chum salmon migration occurred over 42 days. The onset began on July 18, midpoint on August 1 and the end was on August 29 . At Sunshine Station, 58 miles above Flathorn Station, the migration was shorter in duration lasting 27 days . The migration therP. began on July 23, reached a midpoint on August 4 and ended on August 19.

Chum salmon migrated slower or milled more in the lower sub-river reach between Flathorn Station and the Yentna River {RM 28) than in the sub reach between the Yentna River and Sunshine Station. Migration speeds between stations based on median days traveled computed at 2.5 mpd (Flathorn to Yentna stations) and 4.5 mpd (Flathorn to Sunshine stations). In 1984 chum salmon migrations in the lower river reach fluctuated at least twice in season probably due to high flows {Figures 40 and 41). For example the highest river flows from mid July to mid August in the Yentna and Susitna rivers occurred on July 27 and 28 {USGS, provisional dataL On these same dates, there was a s harp drop in chum salmon catches in the fishwheels operated at Flathorn (RM 22), Yentna (TRM 04 ) -116- J I I I I I I I I I I I I I I I I I I I I I I I I I Figure 42.

Station (RM 22) migrated in the east channel and within that channel most (69~) of the fish passed along the left bank (looking upstream) based on fishwheel catches. The west channel at Flathorn Station passed about 17 percent of the escapement . Most (87%) of the fish in the west channel migrated along the right bank. In the Yentna River about 57 percent of the chum salmon passed Yentna Station (TRM 04) along the south bank as indicated by fishwheel catcHes. The same trend was also observed with the SSS counters . About 60 percent of the chum salmon counts at Yentna Station were registered by the south bank sonar (Appendix 3). At Sunshine Station (RM 80) chum salmon were mainly along the east bank as the east bank wheels caught 92 percent of the station catch and the wes t bank wheels caught the remaining eight percent. -118- I I I I I I I I I I I I I I I I I I I Chum salmon released at Flathorn Station {RM 22) with numbered tags were recaptured in the Yentna River {RM 28) at Yentna Station {TRM 04) and at Sunshine Station (RM 80) and above at RM 103 and 120 (Table 35 and Figure 44). Based on the recapture information about 95 percent of the chum salmon that entered the Yentna River migrated in the east channel at Flathorn Station. The remaining five percent, passed Flathorn Station in the west channel. The east channel at Flathorn Station was also favored by chum salmon reaching RM 80 and above. The east channel passed about 83 percent of these fish and the west channel, 17 percent. Chum sa 1 mon escapements were samp 1 ed for age, 1 ength ( FL) and sex composition at Flathorn (RM 22), Yentna (TRM 04) and Sunshine (RM 80) stations in 1984. The results indicate that nearly oll (99.2-99.9 ~) the chum salmon returning to these stations were three, four and five year old fish (Figure 45 and Table 36). Most prevalent were four year olds, accounting for 73.9 percent, 69.2 percent and 75.7 percent of the respective escapements to Flathorn , Yentna and Sunshine stations. All adult chum salmon returning to these stations in 1984 had migrated to sea as juveniles in their first year of life based on scale analysis . The average chum salmon lengths at Flathorn, Yentna and Sunshine stations in 1984 was 585 mm, 584 mm and 594 mm, respectively (Table 37 and Appendix 5). At all stations male chum salmon averaged between 11 and 20 mm longer than the f emales. Expectedly, the larger length fish were generally in the older age classes (Table 37). In 1984 there were more female than male chum salmon in the lower river reach except at Yentna Station (Table 38). The male to female escapement ratios were 1.1:1 (Flathorn Station). 0.7:1 (Ye ntna Station) and 1.1:1 (Sunshine Station). -119- Table 35.

As indicated in Figure 39 about 12 percent of the escapement migrating past Flathorn Station (RM 22) reached Talkeetna Station (RM 103) and 13 percent of the escapement passing Sunshine Station (RM 80) were Talkeetna Station bound fish. Comparatively around six percent of the escapement migrating past Flathorn and Sunshine stations reached Curry Station (RM 120) in 1984 . In the middle river reach an estimated 26,060 chum salmon spawned in sloughs (14,634 fish), streams (7 ,628 fish) and mainstem (3,798 fish) habi~ats {Section 3.1.4.2.2). Based on these figures about 75 perce,nt of the chum salmon escapement to Talkeetna Station and 45 percent of the Curry Station escapement were milling fish that spawned below these stations mainly in the lower river reach. Chum salmon catches in the fishwheels at Talkeetna Station {RM 103) totaled 12,749 fish and at Curry Station {RM 120), 4,228 fish {Table 6). These catches represent about 13 and 9 percents of the respective, stations escapements. In 1984 chum sa1mon migrated in the Susitna River mainstem over a five to six week period based on fishwheel catches at Talkeetna (RM 103) and Curry {RM 120) stations {Appendix 2). At Ta "ikeetna Station, the migration began on July 25, reached a midpoint on August 5 and ended on August 15. Seventeen miles upstream at Curry Station the respective dates were July 28, August 5 and August 21. -125- Chum salmon migrational rates based on tag r ecoveries in the lower and middle river reaches in 1984 are presented in Appendix 2 and summarized in Figure 42 . Chum salmon tagged at Sunshine Station (RM 80) in the lower river reached Talkeetna Stati on (RM 103) generally in four to five days and Curry Station (RM 120) in six days. Travel time between Talkeetna and Curry stations usually took two days . Comparing the migration rates between stations using the median number of days traveled, chum salmon averaged speeds of 5.8 mpd (Sunshine to Talkeetna stations), 6.7 mpd (Sunshine to Curry stations) and 8.5 mpd (Talkeetna to Curry stations). Chum salmon migrated faster or milled less the further they migrated upstream ev i dent by the travel speeds above. In 1984, chum salmon were about equally dtstributed between the east and west banks at Talkeetna Station (RM 103) as determined from fishwheel catches (Appendix 2). The east and west bank fishwhe~ls respectively caught 46 and 54 percent of the station catch. At Curry Station (RM 120) chum salmon were more plentiful along the west ban k than the east ban k at that location (Appendix 2). The east bank fishwheel caught 75 percent of the station catch and the west bank fishwheel caught the remaining 25 percent. Overall, chum salmon fishwheel catches at Talkeetna (RM 103) and Curry (RM 120) stations were normally distributed through the 1984 migration period (Figure 46). The exception occurred late in the first week and early in the second week of August at both stat i ons. At TalkeetrA and Curry stations fishwheel catch rates generally rose sharply between the third week of J uly and the midpoint of the first week of August and then -126- ~ I I I I I I I I I I I I I I I I I I I I I I I I I q) Q) .c. 3 ' L. :J 0 :r: ' .c.

Comparatively, river flows at Gold Creek (RM 137) during the chum salmon migration generally decreased an average of 900 cf! daily during the first half of the migration (7/25-8/5) and then rose about 3,000 cfs over the next four days (8/6-B/10) and then declined about 340 cfs daily through the second half of the migration period (8/10-21) (Figure 8). The sm~ll surge in fishwheel catches recorded late in the second week of August at Talkeetna and Curry stations may be related to the ri se in river flow that occurred a few days earlier. Chum salmon mig:ating to Talkeetna and Curry stations likely slowed their travel speed at the initial rise in river discharge and then excellerated their travel speed after the peak rise. Other studies support this conclusion. For example radio telemetry work in 1981 and 1982 in the same river reach indicate chum salmon typically respond to high water flows by reducing their migration speeds (ADF&G, 1981 and ADF&G, 1982). Chum salmon migrating off the east and west banks at Talkeet~a Station (RM 103) displayed differential behavior in respect to destination and crossover as determined from 243 tagged numbered, chum salmon released at Talkeetna Station and recaptured at Curry Station (RM 120) (Table 39). The majority, 76 percent, of the Curry St~tion chum salmon escapement were fish that passed Talkeetn ~ Station along the east side of the river (Table 39). The remainder, 24 percent, were west bank migrating fish at RM 103. With respect to crossover, a higher percentage of the east bank than west bank migrating fish at Talkeetna -128- 1 I "j I I I I I I I I I I I I I I Table 39.

A representative age, length (FL) and sex sample was collected from middle river chum salmon escapements to Talkeetna (RM 103) and Curry (RM 120) stations in 1984. The escapements to both stations were comprised of three to six year old fish (Table 36 and Figure 45). The majority (69-71~) of the fish wer£: fc;,r year olds followed by five year olds (17-23t ). All the chum salmon reaching Talkeetna and Curry stations in 1984 had migrated to sea as juveniles in their first year of life. Chum salmon lengths at Talk~etna Station 1n 1984 averaged 8 mm longer than at Curry Station {Appendix Figures 5-19 and 5-20). The respectiv~ length avP.rages were 605 mm and 597 1m1. As expected, the longest lengths were represented in the older age classes. Overall males averaged 12 mm more length than the females at both stations. Also male chum salmon were more abundant than females (Table 38). The male to female ratio at Tal keetna Station was 1.4:1 and at Curry Station 2.0:1. -129- I 1; 3.1 .4.2.2 Spawning Ground Surveys 3.1 .4.2.2 .1 Mainstem In 1984, 36 mainstem chum salmon spawning areas were identified in the Susitna River middle reach (Figure 47). Nine sites were found downstream of Curry Station (RM 120) and 27 upstream. The earliest date chum salmon were observed spJwning in the mainstem 'was on September 1 and the latest on September 29, 1984 (Appendix 6). The peak spawning likely occurred in the first and second weeks of August based on peak, live fish counts. However, spawning may have peaked as much as a week earlier. Due to the turbid, ~'instem conditions through the month of August in 1984, survey visibility was 'poor'. This essentially prevented documentation of earlier spawning, if present. The peak cou~t of live chum salmon in the 36 mainstem spawning areas in 1984 totaled 1,266 fish. Assuming this count represents about a third of the total population, approximately 3,800 fish spawned in the middle mainstem Susitna River reach in 1984. The basis for expanding the peak count by a factor of 3.0 is based on information in report section 3.1 .4 .2.2.3 and Barrett et al, (1984) that indicate a peak l i ve and dead count of chum salmon represents about 50 percent of an actual escapement under ideal survey conditions . Considering that there were 'poor', mainstem survey conditions in late August near the peak spawning period and dead fish were not counted due to the uncertainty of their origin, an expansion factor of 3.0 was considered reasonable . -130- I I I I I I I I I I I I I I I .I II ~ II Indian Crt111k Stati on Location Spa"nlng Ha p ld Highest Observation Map ld Nunber RR Biiik Fish Count Dates Num ber 1 100,9 R 89 9 /15-29/84 19 2 110.1 L 4 9/1-8/84 20 3 114.0 c 46 9/15/84 21 4 114 .6 R 69 9/1-22/84 22 5 115,0 R 15 9/1 -29/84 23 6 1 15.1 R 50 9/8/84 24 7 118,9 L 21 9/1-15/84 25 8 119 ,1 L 15 9/1-15/84 26 9 119.4 L 2 9/8/84 27 10 120 .9 L 5+redds 10/13/84 28 11 121 .6 R 2 9/15/84 29 12 124.0 L 18 9/22/84 30 13 124.9 C" 8 9/8-29/84 31 14 128.3 R 73 9/8-15/84 32 15 128.6 R 77 9/1-29/84 33 16 129 ,8 R 18 9/1-15/84 34 17 130.0 R 5 9/8/84 35 18 130.5 R 36 9/1-15/84 36 Figure 47.

In relation to the total estimated escapements to t hese stations, about 3.6 percent of the Talkeetna Station escapem ent spawned in the mainstem above P.M 103 and 5.8 percent of the Curry Statior escapement spawned above RM 120 in the mainstem . 3.1.4.2.2.2 Streams In 1984 , 11 streams were occupied by chum salmon in the middle river reach (Appendix Table 6-2). Peak spawning ground counts of these streams totaled 3,814 fish (Table 40). The majority , 9~ percent, of the fish counted were in Indian River (RM 138.6) ,· Portage Creek (~i-1 148.9) and Fourth of July Creek (RM 131.1) (Figure 48). Spawnir;g in these streams extended from about the last week of July through the first week of October. Peak spawning occurred in the second and third weeks of August (Appendix Table 6-2). The chum salmon spawning areas and upper limits of migration for the occupied streams in 1984 are illustrated in Appendix 6. Spawning occurred in the Susitna River interface of most of these streams. In Jndian River (RM 138.6) chum salmon spawned in the first nine miles with major spawning occurring in the first two miles. At Portage Creek (RM 148 .9) chum salmon extended about 7.5 miles upst:ream to Thorofare Creek {TRM 7.5). Spawning was discontinous in this reach. Chum salmon entering Fourth of July Creek (RM 131.1) spawned from the Susitna River interface to a point about 1.5 miles upstream. The major spawning was i~ the Susitna River interface. j u .I I I I I I -132----------------~ I I I I I I I I I I I I I I I Figure 48.

As illustrated in Figures 49 and 50 relatively high counts of live chum were recorded by ground and helicopter surveys in the index reach of these streams through the entire spawning period . About 45 percent of the peak helicopter chum salmon count was recorded in the first one mile reach of Indian River, and 21 percent o~ the peak count of Portage Creek was 1 ogged in the first one-quarter mi le. These percentages indicate that both lower reaches or specifically the first one mile of Indian River and the first one-quarter mile of Portage Creek were major chum salmon spawning areas in 1984 . The 1984 chum salmon escapement to mi ddle reach su,itna River streams was approximately 7,628 fish. This estimate was determined by expanding the total peak count by a 2.0 facto r which assumes a peak count represents 50 percent of the actual escapement {Table 40) (Cousens et al, 1982}. A 11 the chum salmon spawning in middle reach streams occurred above Talkeetna Station (RM 103) and 98 percent occurred above Curry Station (RM 120) in 1984 (Table 40). Comparing the estimated chum salmon escapement for middle reach streams to the estimated mainstem escapement at Talkeetna and Curry stations it can be determined that about 8 percent (7 ,628) of the escapement reaching Talkeetna Station and 15 percent (7,482 fish) of the Curry Station escapement were stream s pawning fish. -134- I I I I I I I I I I I I II I I I I I I 0 LIJ .... z :::> 0 (.) z 0 :i ..J <t en ~ :::> :X: (.) w 2:: ..J lL. 0 0:: LLJ m ~ :::> z ~00 INDIAN R I VER 2000 Groun d sur v e~ of the fir st T M . ---Hel i copter surv ey of t he first T R M.

A total of 128 of these marked chum salmon entered the three sloughs (Figure 51). The mean average time spent by these fish from being tagged and slough entrance was 19 days (Figure 51) .. The averages ranged from 14.1 days for Slough A' fish to 20.4 days for Slough 11 fish.

Considering this travel speed it is probable that the majority of the average 19 days chum salmon spent between Curry Station and entering sloughs A• (RM 124.6), SA (RM 125.1) and 11 (RM 135.3) was time ripening in the Susitna River mainstem . Further evidence of a several week ripening period can be found by comparing the peak chum salmon fishwheel catches at Talkeetna and Curry stations with peak chum salmon live counts in sloughs upstream (Figure 46 and Appendix Tab 1 e 6-3) • A severa 1 week 1 a'g occurred between the time chum sa 1 mon passed these tagging stations and fish entered sloughs SA, 11 and 21 . (Section 3.1.4 .2.1). Also in 19S4, numerous chum salmon were observed spawning in habitats miles downstream of where they were tagged which provides direct evidence that not all chum salmon migrate directly to their spawning area (Appendix Table 6-1). Milling or straying upstream of a spawning area is probably a secondary response to fish using the mainstem for ripening more than a by-product of fish seeking out a new spawning habitat or not initially recognizing a natal area. Chum salmon occupying sloughs A' (RM 124.6), SA (RM 125.1) and 11 (RM 13.5.3) 'i n 19S4 had an average observation life of 6.S days (F i gure 52). The lowest average observation life was at Slough 11 (6 .1 days) and the highest at Slough SA (7.9 days). The observation life estimates identified above reflect the average number of days individual chum salmon occupied three sloughs of the middle Susitna River reach in 19S4. These estimates do not, however, represent the spawning life of chum salmon in these sloughs because not -139- I -~ 0 I --10 10 l•o ~ .. ~ z "' ¥10 "' a. 10 ...--..... ......-......

Some of the chum salmon which entered these sloughs spawned elsewhere. At least three of the 131 chum salmon monitored at sloughs A' (RM 124.6), SA (RM 125.1) and 11 (RM 135.3) entered more than one slough. For example, one chum salmon entet•ed Slough SA, remained there for about a week and then left and four days later entered Slough 11 where it spawned over a period of 11 days. About 1S percent of the chum salmon monitored for observation life were only located once in the three study sloughs and because these fish were never relocated or observed spawning, many were probably using these sloughs for milling or ripening purposes only. An unknown percentage of the fish observed but once, however, may have been removed by predation, namely by bears which c011100nly fed at these sloughs. Overall, 1S .S percent {mean average) of the monitored fish at sloughs A', SA, and 11 did not initiate spawning in the slough of first recorded entry. The lowest percentage (14.3S) occurred at Slough A and the highest (25.3S) was recorded at slough 11 (Table 41). The spawning distribution of chum salmon monitored for observation life in sloughs SA {RM 125.1) and 11 (RM 135.3) is outlined in Table 41. The distribution figures indicate that for these sloughs chum salmon spawning in 19S4 was relatively light at the c~nfluence. The lower slough reaches were used more for spawning than the upper slough reaches. In comparison, sockeye salmon spawned more in the upper areas of these sloughs than in the lower areas (Section 3.1.2.2.2.2.3). -141- Table 41 • Slough wi th RM n ll !:.I A' 7 RM 124 .6 SA 30 RM 125.1 11 94 RM 135 .3 Percentages of chum salmon monitored for observation life that i ni tiated spawning by habitat zone at sloughs A', SA , and 11, 19S4.

Susitna River coho salmon also contribute to a growing recreational fishery (Mills, 1983). Within the Susitna River drainage there are a minimum, 25 spawning popula·tions (ADF&G, 1982 and ADF&G, 1983). The majority spawn in the lower Susitna River re'lch below RM 80 (ADF&Ii, 1982). The minimum Susitna River escapements for the three previous years have been 37,000 fish (1981), 80 ,000 fish (1982} and 24,100 fish (1983) (Barrett et al, 1984). These minimum estimates do not include escapements to systeas below RM 80 except the Yentna River (RM 28}. The minimum 1984 coho salmon escapement based on a Petersen tag and recapture estimate at RM 22 was 190,100 fish (Section 3.1 .5.1 .1). The fo 11 owing report subsect 1 on presents the resu 1 ts of samp 1i ng the 1984 coho salmon escapements in the Susitna River lower and middle reaches. 3.1.5.1 Lower River 3.1.5.1.1 Main Channel Escapement Monito r ing The 1984 coho salmon escapements were est imated for the Susitna River -149- lower reach at Flathorn (RM 22), Yentna (TRM 04) and ~unsMne (RM 80 ) stations . The estimated escapements to these stati ons were 190,100 fish (Flathorn Stat1on), 18,200 fish (Yentna Station) and 94,700 fish (Sunsh i ne Station) (Tables 45 and 19, and Figure 55). Estimated escapements were derived by the Petersen tag and recapture metnod at Flathorn and Sunsh i ne stations and by SSS at Yentna Station.

The minimum coho salmon escapement into the Susitna River drainage was 190,100 fish in 1984 as defined by the estimated escapement to RM 22. Below RM 22, only Fish (RM 7.0) and Alexander (RM 9.8) creeks drainages are known to s upport coho salmon spawning populat ions (ADF&G , 1982). The coho salmon escapements to these drainages are not included in the minimum Susitna River escapement. The historic peak survey counts were 380 fish i n Re d Shirt Creek (1952) (Fish Creek drainage) and 2,000 f ish i n Ale xa nder Creek (1964) (ADF&G, 1982). The geographic distribution of coho sa lmon i n the lower Susitna River -151- reach above RM 22, based on 1984 escapement mon;toring at Flathorn (RM 22), Yentna (TRM 04) and Sunshine (RM 80) stations, is illustrated in Figure 55 . As shown, escapements to Yentna and Sunshine stations account for about 60 percent of the escapement to RM 22. The remaining 40 percent of the escapement which reached RM 22 spawned in the Susitna River reach below RM 80 excluding the Yentna River. The coho salmon migrational timing at Flathorn (RM 22), Yentna (TRM 04) and Sunshine (RM 80) stations was determined from 1984 station fishwheel catches (Figures 56 and 57, and Appendix 2). The migration at Flathorn .. Station . extended for approximately five weeks, from July 18 to August 21. The migration midpoint occurred on July 29 in the east channel and on July 25 in the west channel. There is little difference between east channel and west channel coho salmon passage timing at RM 22, based on fishwheel catches . In the Yentna River (RM 28) at Yentna Station the coho salmon migration covered approximately a one mont.h period, from July 21 to August 22. The migration midpoint was on August 3. At Sunshine Station coho salmon were generally present 30 days, from July 29 to August 29. The migration midpoint was August 11 (F i gure 57). Coho salmon migratory distributions at Flathorn (RM 22), Yentna (TRM 04) and Sunshine (RM 80) stations were based on 1984 station fishwheel catches (Table 6 and Appendix 2). At RM 22 the Susitna River is divided into two channels by a large island complex. Fishwheels were deployed off both mainland banks and off each side of the largest island . Each wheel was individually identified by channel (east or west) and bank (right or left) (Appendix Figure 1-1).

The majority of the coho salmon (55.1 percent) migrated in the east channel at RM 22. These data also indicate a strong preference by coho salmon to migrate midriver at this s i te. The two mi driver fishwheels i ntercepted a combined 72.3 percent of the total catch. In the Yentna River (RM 28) at Yentna Station coho salmon migrated primarily (81.4 percent) along the south bank, based on fi s hwheel catches . At Sunsh i ne Station a total of 57.9 percent of the fi s hwheel catch were i ntercepted in the two eas t bank wheels and 42.1 percent in the two west bank whe £'1s.

Based on the tag recovery data about 67 percent of the coho salmon reach i ng Yentna Station migrated in the ea st channel at RM 22. The remaining 33 percent migrated i n the west channel. Coho salmon reaching RM 80 and above also passed RM 22 predominately (90 percent) in the east channel. Table 46.

The slower coho salmon travel rate between Flathorn and Yentna stations was probably due to milling activity in the vicinity of the Susitna and Yentna (RM 28) rivers confluence. Age, length (FL ) and sex composition information was collected from the coho salmon escap~ents reaching Flathorn (RM 22), Yentna (TRM 04) and Sunshine (RM 80} stations in 1984. The majority of the coho salmon reaching all three stations were four year old fish representing 64.4, 70.0 and 64.4 percents of the escapements, respectively (Table 47 ·and Figure 60). Three year o ld fish were the second most abundant at all three sites. A total of 34.3, 27.9 and 34.2 ~erce nts of the coho salmon returning to Fla t horn, Yentna and Sunshine stations, respectively, had previously migrated to the ocean (smolted) in their third year of life. The mean length of "the coho salmon escapement to Flathorn, Yentna and Sunshine stations was 543 1m1, 557 1m1 and 546 1m1, respectively (Table 48). The slightly longer average length recorded at Yentna Station was due to a higher percentage of four year old fish returning there than at other stations. At Flathorn and Ye ntna stations males were generally larger than females. At Sunshine Station the male and female average 1 engths were the same. The coho sa 1 mon escapement ma 1 e to fema 1 e sex ratios at Flathorn, Yentna and Sunshine stations were 1.4:1, 0.8:1 and 1.?.:1, respectively (Table 49).

All samples were collected on Aug~st 22. The average fecundity of the 22 samples was 2,964 eggs per female and ranged from 1,394 to 3,984 eggs (Table 50). The fecundity samples -161- were collected prior to the eggs reaching full maturation and they became fragile and difficult to count after freezing and thawing. These difficult1es introduced an unknown error component in the analysis . Table SO.

This estimate assumes that coho salmon stocks sampled on August 22 were mixed and repre sentative of the entire escapement . Susitna River coho salmon fecundities may be greater than reported for other Alaskan and Canaoian stocks. Hart (1973} reports the mean fecundity of 550 mm coho salmon at 2,500 eggs. The fecundity of similar sized Susitna River coho salmon, based on regression analysis, would be 2,860 eggs or 360 more than reported by Hart. These data were derived from regressions of length and weight to fecundity which had respective correlation coefficients (r2) of 0.4 and 0.5 indicating only a 'fair ' r e lationship between the variables (Figure 61}. -162- ------------------- • • • • • • 515 • • • • 3500 • • Sl50 Sl50 I l2 (lJ a. • w w ~ 2100 21 ~ 0 0 c c "' w .....

About 11,800 coho salmon migrated to Talkeetna Station by this method. The 95 percent confidence interval assoc i ated with this estimate is 10,500 to 13,600 fish. Seventeen miles upriver, the estimated escapement to Curry Station was 2,200 fish. This estimate had a 95 percent confidence interval of 1,500 to 3,700 fish {Table 45). The 1984 coho salmon migrations reaching Talkeetna {RM 103) and Curry {RM 120) stations comprised 6.2 and 1.2 percents, respectively, of the minimum Susitna River escapement as recorded at RM 22 (Figurl.! 55). Based on the estimated number ~f coho salmon spawning above RM 103 and RM 120 about 75 and 45 percents of the Talkeetna and Curry stations coho salmon escapement returned downstream to spawn below the respective sites (Section 3.1.5.2.2.2). Based on fishwheel catches coho salmon were genet·ally abundant at Talkeetna Station (RM 103) in 1984 about four weeks, from July 31 to August 29 (Appendix Table 2-14). The migration reached a midpoint on August 12. At Curry Station (RM 120) coho salmon were present also about four weeks, from August 1 to August 28. The migration median was August 11. -164- l I I I I I I I I I I I I I I . I I I I I I I I I I Fishwheel interceptions at Talkeetna (RM 103) and Curry {RM 120) stations were used to detenm i ne the 1984 coho salmon migrational characteristics at these sites (Figure 62). A total of 1.526 coho salmon were captured by fishwheels at Talkeetna Station. The west bank fishwheels accounted for 79.8 percent of the catch indicating a strong preference by coho salmon to migrate along this bank at RM 103. At Curry Station a total of 350 coho salmon were intercepted. The west and east bank fishwheels intercepted 53.3 and 46.7 percents of the station catch indicating a slight preference by coho salmon to west bank migration at RM 120. A total of 1.034 coho salmon were marked with Floy FT-4 spaghetti tags at Talkeetna Station (RM 103} in 1984 (Table 6). At Curry Station {RH 120). only six Talkeetna tagged fish were recovered. an insufficient number to evaluate differential milling or bank crossover of coho salmon stocks migrating between RM 103 and RM 120. Coho salmon migrational rates were based on tag recoveries in the lower and middle Susitna River reaches in 1984 (Appendix Table 2 and Figure 59). Coho salmon traveled about eight days between Sunshine (RM 80) and Talkeetna {RM 103) stations and about six days between Talkeetna and Curry (RM 120} stations . The respective migrational speeds were 2.9 mpd and 2.8 mpd. The 40 mile distancP betwee~ Sunshine and Curry statio~s was· traveled by coho salmon in an average 16 days which calculates to a travel sp~ed of 2.5 mpd. -165- Gl Gl J:. :I ' L. ' 0 J: ' J:.

Based on this information, the escapements to bot'' Talkeetna and Curry stations were primarily four year old fish, 67.3 and 52 .4 percents, respectively (Table 47). The relati\'ely low percentage of four y ~ar old fish recorded at Curry Station as compared to Talkeetra Station was probably due to milling activity among coho salmon stocks l .t RM 103. A total of 67.~ percent and 51.8 percents of the coho salmon escapement at Talkeetna and Curry stations, respectively, migrated ·:o the ocean (smolted} in their third year of life. The average C01 \0 salmon lengths recorded at Talkeetna and Curry stations were 559 mm a'd 531 nn (Taole 48). The smaller average coho salmon length at Cur~ Station is du e to a larger percentage of three year old fish at th i s station. The ceho salmon male to female sex ratios at Talkeetna a nd Curry sti.:tions were both 1.1:1. Generally, males were more abunda11t than females at both stations (Table 49). 3.1.5.2.2 Spawning Ground Surveys 3.1 .5.2.2.1 Mainstem In 1984 the Susitna River mainstem middle reach was repetitivell' surveyed between July 21 and October 14 for salmon spawning using helicopter and waterbourne craft (Appendix Table 6-1 ). On August 24, two coho salmon were observed spawning off the Susitna River west bank at RH 131.5 (Appendix Figure 6-16). This was the only coho salmon spawning location identifi~d in the mainstem middle reach. -167- l 3.1.5.2.2.2 Sloughs and Streams A total of 37 sloughs and 25 streams between RM 98.6 and 161.0 were surveyed in 1984 to determine the distribution of coho salmon in this river reach (Appendix Tables 6-2 and 6-3). These surveys were conducted from July 21 to October 14. Coho salmon were observed in three of the 37 sloughs surveyed. ihe fish observed in sloughs Moose (RM 123.5), 11 (RM 135.3) and 15 (RM 137.2) were considered milling not spawning fish based on single sightings, no observed carcasses and no observations of spawning activity. Coho salmon were observed in 10 of 25 middle Susitna River reach streams surveyed in 1984 (Appendix Table 6-2). These surveys, like the slough surveys, were conducted from July 21 to October 14. The peak live and dead coho salmon survey count of the 10 streams was 1,434 fish. Based on peak survey counts, the majority (70.1 percent) of the coho salmon in this river reach were in Indian River (RM 138.6), Whiskers Creek (RM 101.4) and Chase Creek (RM 106.9) (Table 51 and Figure 63). Stream surveys were one of two types, foot or helicopter surveys . Foot surveys were conducted for a pre-determined reach of each stream. The counts from these surveys were used as an index of relative abundance and do not reflect the actual escapement to each stream. Stream helicopter surveys were conducted for the entire distance known to support salmon spawning. These counts may be adjusted for the stream 1 ife of a particular species and the helicopter survey efficiency. Once these adjustments have been .performed an estimate of the total escapement to a particular stream is possible. -168- E I I I I I Table 51. I Str eam I nd ian Ri ve r Whiske r s Cr .

Based on these helicopter surveys the upper limit of migration in Whiskers Creek {RM 101.4), Chase Creek (RM 106.9) and Indian River (RM 138.6) was 0.9 miles, 1.1 miles and 8 .7 miles, respectively. Coho s almon in Whiskers Creek spawned intermittently to the upper limit of their migration (0.9 miles). The most i mportant spawning area observed in Whiskers Creek was the interface with the Susitna Rive r. In Chase Creek coho salmon spawning occurred discountinuosly to the upper migration limit (1.1 miles ). Coho salmon spawned throughout the Indian River from the Susitna River interface to 8.1 miles upstream. Two major co ho salmo n spawning reaches were located in Indian Rher from TR M 2. 7 to 5.3 and from TRM 7.6 to 8.1. Major coho salmon spawning was also observed in a small tributary that feeds into Indian River at approximately TRM 8.1. The relative importance to coho salmon spawning in the lower reaches of Indi an River (RM 138.6) and Portage Creek (RM 148.9) can be determ i ned by helicopter surveys (Figures 64 and 65). The peak helicopter survey after September 1 of the lower reach of Indian River (1.0 mile } and Portage Creek (0.25 mile) compared to the peak survey of the entire drainages after September 1 indicate about 14 and 1 percents of the respective streams escapement spawn in the lower reaches. Prior t o September 1 (August 19) a large movement of coho salmon into the Portage Creek i ndex area was recorded. This mo~ement coincides with an increase in Susitna River discharges from about 14,000 cfs on August 15 to 32,000 cfs on August 28 (Figure 8). These milling fish had apparently returned -170 - I I I I I I I I ,.... I I I I I I I I I I to the Susitna River--Portage Creek confluence area by September 1 when the Susitna River discharge had dropped to about 13,000 cfs . The minimum escapements of coho salmon which spawned in the middle Susitna River reach above RM 120 was 1,200 fish in 1984. This estimate was derived assuming that peak survey counts of coho salmon represent approximately 50 percent of the escapement to each stream (Cousens et al , 1984}.

Flow, water quality and temperature changes may occur in the slough, side channel, main channel, and stream habitats utilized by spawning salmon. Information on the magnitude and timing of salmon spawning in these habitats is necessary to assess potential impacts and to plan appropriate mitigation measures. 2.0 Objectives 1) Identify all salmon spawning areas i . main channel, side channel, slough and stream habitats in the lower Susitna River (RM 28.0-RM 98.6). 2) Identify the general habitat characteristics of those areas utilized by ~pawning salmon. Anadromo•Js fish species addressed in this report are: Pacific Salmon Chinook salmon Sockeye salmon Pink salmon Chum salmon Coho salmon A290 Oncorhynchus ~ .Q.:_ tshawytscha 0. nerka ---- 2.:. gorbuscha 0. keta 0. kisutch -~ I 3.0 Methods 3.1 Mainstem and Slough Habitat Aerial surveys were conducted weekly on the lower Susitna River (RM 28.0-RM 98.6) (Figure 1) from July 21 to October 17, 1984 to identify sites utili!ed by spawning salmon (Plate 1). Potential spawning sites were then s urveyed on foot to verify actual spawning activity. Verification of spawning was done visually, observing redds (Plate 2) and salmon spawning activity (Plate 3). To confirm the visual observations, all sites were sampled using standard egg pump ing equipment and methods (Plate 4) to determine the presence of salmon eggs. Spawning areas were then mapped with the species, number of live and dead salmon, number of redds and upwelling activity noterl. Complete survey methods can be found in Section 2.2.1 of Barrett et al, 1985. An aerial survey of the lower river (RH 26.0 to RH 96.0) was conducted by R&M Consultants on March 18, 1983 (Coffin, 1983). During this survey, open leads were delineated on 1:2000 blue line maps . No attempt was made to distinquish between velocity leads and warm water leads . This information served as an indicator to possible spawning areas. 3.2 Stream Habitat Seventeen streams in the lower Susitna River reach (RM 28.0 to RM 98.6} were surveyed in 1984 to provide information on the magnitude, timing and distribution of chinook , sockeye, pink, ch~ and coho salmon spawning in stream mouth reaches (Figure 1).

Survey efforts were concentrated in the i nterface reach of each s tream to eva 1 uate s pawning utilization of these habitats . Streams i n the lower river reach genera l l y had lower gradients t han those in the middle river reach . Lower grad i ent streams usually have more backwater area t han those with a steep gradient {AOF&G , 1983a). At each of the lower river stream interf ace reaches , habitat da t a consisting of stream channel widths, depths and substrate composition were collected at two main s tem discharges . In additi on to habitat data, backwate r effects were al so a s sessed to determine effects of mainstem discharge on interface reaches . Complete survey methods can be found in Section 2.2 .1 of Barrett et al, 1985 . 4.0 Results and Discussion 4.1 Mainstem Habitat The mainstem habitat is comprised of main channel and side channel habitats. Main channel hab i tat is t ypi call y characterized by hi gh water velocities and well armored streambed s (adapted from Sautne r et al, 1984}. Si de channel habitat is char~c ter i zed by shallower depth s , lower velocities and smaller streambed materials than the adjacent habitat of the main c hannel river (adapted from Sautner et al, 1984). For a more complete description of these habitat-types, the reader should consult the glossary at the end of thi s report . For the purpo ses of this s tudy, the main channel habitats and side channel habitats are class ified as A297 I I I I I I I I I I I I I I I I I I I mainstem habitats. Determination of the physical and hydraulic characteristics necessary to accurately define each habitat type was beyond the scope of this study. Survey conditions prior to late September were poor due to high water a~d turbidity level s. As a result, surveys conducted prior to this time may not have observed all spawn i ng act i vity that may have been present. A flood in early September eliminated all sigr.-; of spawning prior to that time. Lower water and turbidity levels in early to late fall improved the survey conditions, increasing the number and accuracy of spawning observations. Surveys identified 13 mainstem salmon spawning sites in the lower river reach (RM 28.0 to RM 98.6) in 1984 (Figure 2). Chum salmon were the predominant species, utilizing 12 mainstem sites for spawning. Coho salmon were observed spawning in only two mainstem sites. The other three species of Pacific salmon were not observed spawning in mainstem sites. Individual site descriptions and maps can be found in Appendix A. An estimate of the total spawning escapement uti li zing mainstem sites in this reach can be determined by using procedures outlined in Barrett et al, 1985. · By using the total live peak escapement counts, it is estimated that 2,754 chum salmon (0.3% of the minimum estimated Susitna River escapement) and 309 coho salmon (0.2% of the minimum estimated Susitna River escapement) utilized mainstem spawning sites between PM 28.0 ~nd RM 98.6 during 1984.

Mains tern salmo n spawning areas ident i fied in the lower reach of the Susitna River between RM 28.0 and RM 98 .6 l in 1984 . A299 I I I I I I I I I I I I I I I I I I I Based on peak live counts, the three most important mainstem sites for chum salmon (in descending order of importance) are : Trapper Creek side channel (RM 92.0C-RM 94 .5L); Sunset side channel (RM 87.0R) and collective ly the four sites in the mouth of the Chulitna River (RM 98 .0L). The rest of the mainstem sites contained less than 50 fish. The most important mainstem site for coho salmon is the Trapper Creek side cha nnel (RM 92.0C-~M 94 .5L ) followed by the Sunset side channel (RM 87. 5R). Upwe 11 i ng, bank seepage or winter open 1 eads were observed in nine of the sites. The predominant sites utilized by chum salmon and both sites used by coho salmon all had associated upwelling/bank seepage. Closer examination may find upwelling/bank seepage in all or some of the remaining sites where it was not observed in 1984. Chum salmon selecting upwelling areas in which to spawn was reinforced by the data. 4.2 Slough Habitat 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 al, 1984). A feature that distinguishes side slough habitat from side channel habitat is the side sloughs convey clear water form small tributaries and/or upwelling groundwate1 in an unbreached condition (Sautner et al, 1984). The reader should consult the glossary for a comp l ete descr i ~tion cf slough habitats. The salmon spawning sites located in this study all fall in the side slough category and will all be referred to as slough habitats. A300 Survey conditions encountered in slough surveys are identical to those already described under mainstem habitat. As mainstem discharges fell in late fall, survey conditions improved, increasing the number and accuracy of spawning observations. Salmon were obs erved spawning in six slough sites in the lower river reach (RM 28.0 to RM 98.6) in 1984 (Figure 3). As was found with the mainstem spawning sites, chum salmon were the predominant species utiliz i ng sloughs for spawning. Of the 6 slough spawning sites, chum salmon u s ed five while coho salmon used one. The other three species of PacHi c sal mo n were not observed spawning i n s lough sites surveyed. Individual site descri ptions and maps can be found in Appendix A. It is estimated that 656 chum salmon (0. n of the min i n.Jm estimated Susi tna River escapement) a,d 12 coho salmon ( 0 . 1~ of the mi nin.Jm esti mated Susitna R'ver escapement) util i zed s lough spawning sites between RM 28.0 and RM 98 .6 during 1984 . Procedures for these calculations using peak live and dead counts can be found in Barrett et al, 1985 . Utilizing peak l i ve counts, the mo s t important s lough sites for chum salmon (in descending o rder of importance) are: Cache Creek Slough (RM 96.0L) and Musher Slough (RM 95.21\~. The remaining three slough sites utiliJed by chum salmon had less than fifty fish . The onl y slougn site found to have spawning coho salmon was Rustic Wilderness Slough (RM 57.0R).

Upwe 11 i ng, bank seepage or winter open 1 eads were observed at four sites. The most important chum salmon site had no upwelling observed. This does not mean that upwelling is not present. Th i s site has a creek associate\.1 with i t wh i ch might provide adequate flows and supplies of dissolved oxygen in the absence of upwelling . As has been found in the mainstem sites and previous studies, chum salmon appear to be selecting upwelling areas for spawning sites. 4.3 Stream Habitat Based on habitat observations of the interface reach the seventeen streams surveyed fell into two general categories . The first category had primarily silt-sand substrates wi th tann i n stained water. Lower river streams in this category are: Fi sh Creek (RM 31.2); No Name Creek (RM 31.7 ); Whitsol Creek (RM 35.2); Rolly Creek (RM 39.0); Grays Creek (RM 59.5); and Rabideux (RM 83.1). The second category of streams had substrates ranging from small gravels to cobbles and clear water. Lower river streams in this category are: Willow Creek (RM 49.1); Little Willow Creek (RM 50 .5); Kashwitna River (RM 61.0); Caswell Creek (RM 64.0); Sheep Creek (RM 66.1); Goose Creek (RM 72.0); Montana Creek (RM 77.0); Sunshine Creek (RM 85.1); Birch Creek (RM 89.2); Trapper Creek {RM 91.5); and Cache Creek (RM 95.5). Site maps and descriptions of each creek are in Appendix B. 4.3.1 Chinook Salmon Seventeen streams in the lower Susitna Kiver reach (RM 28.0 to RM 98.6) A303 I I I I I I I .1 I I I I I I I I I I I I I I I I I I I were surveyed for adult salmon spawning activity from July 21 to October 17 in 1984 (Appendix Table 0-1). Of the seventeen streams surveyed, chinook salmon were observed in eleven streams (Table 1). Table 1.

A304 The total peak survey count of chinook salmon in the eleven streams was 3,027 fish (Table 1). The majority were observed in Montana Creek (76. 3~). The remaining 23. 7~ were distributed among the other ten streams as listed in T~ble 1. These counts are not intended to represent the total number of chinook salmon in these streams. Only the first three quarter mile from the stream mouth was surveyed providing an index count to relative abundance. Based on survey observations, chinook salmon were generally abundant on lower river streams in the third week of July. Chinook salmon were observed in Montana Creek from July 23 to August 14 in 1984 with the peak count occurring on July 23 (Appendix Table 0-1). Chinook salmon were not observed spawning in lower river stream interfaces in 1984 (Table 2). Previous data indicates that rubble-cobble substrates are preferred for chinook spawning (AOF&G, 1983b). Habitat data collected in lower river stream interfaces indicates that smaller substrates, primarily silt-sand or gravel-rubble are prevalent in these areas (Appendix Table 8-1). Suitability data also indicates that chinook salmon prefer velocities from 1.7 to 2.3 feet/second for spawning. Although velocity data was not collected in lower river streams in 1984, it is the authors opinion that veloc1ties in the interface areas of these streams are generally less than those preferred by spawning chinook salmon. Chinook salmon were observed in upper portions of many of these streams. AS05 I 1 I I I I I I I I I I I I I I I I I I I Table 2.

Only the first three quarter mile from the stream mouth was surveyed providi ng an index count of re lati ve abundance. Based on survey observations, sockeye salmon were generally abundant in lower river streams during the first three weeks of August (Table 3). Sockeye salmon were observed in Willow Creek from August 6 to August 12 in 1984, with the peak survey count occurring on August 12 (Appendix Table 0-1).

An estimated chum salmon escapement of 3,552 (0.4% of the minimum estimated Susitna River escapement) was observed using mainstem and slough spawning sites in this reach. The estimated escapement of coho salmon spawning in mainstem and slough sites in this reach is 327 {0.2% of the minimum estimated Susitna River escapement). The other species of Pacific salmon were not observed spawn i ng in these habitat types in this reach. Both species appear to be selecting sites that have upwelling or bank seepage associated with them. Compared with the middle reach of the Susitna River from Talkeetna (RM 97 .0) to Devils Canyon (RH 150 .0), mainstem and slough spawning in the lower reach in minimal. There are some sites, such as Trapper Creek side channel, that should have further study and be included in mitigation planning. Studies should be continued to further define spawning areas and conditions in this reach. 5.2 StreaM Habitat 5.2.1 Chinook Salmon A total peak survey count of 3,027 chinook ~almon were observed within the index areas of eleven lower river streams in 1984.

Main Channel Habitat : Consists of those portions of the Susitna River that normally convey water throughout the year. Both single and multiple channel reaches are included in this habitat category. Groundwater and tributary inflow appear to be inconseq uential contributors to the overall characteristics of ma i n channel habitat . Main chan nel 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 su11111er due to the influence of glacial melt-water. Di scharges recede in early fall and the main channel clears appreciably in October. Hainstem Habitat : Consists of main channel and side channel habitats. Side Channel Habitat: Consists of those portions of the Susitna River that nonmally 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 defined channels flowing through partially submerged gravel bars and islands along the margins of the ma i n channel river. Side channel strearrbed elevations are typically A322 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 between the edge of the floodplain and the main channel and si de channels of the Susitna River. It is usually separated from the main channel and/or 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. elevations 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 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 hundr.ed feet of the ~ 1 ough channe 1 often conveys water independent of mainstem backwater effects. At high discharges, the water surface elevation of the mainstcm river is sufficient to overtop A323 j I I I I I I I I I I I I I . I I I I I I I I I I I I I the upper end of the slough. Surface watf·r temperatures in the side sloughs during summer months are princi?ally a function of air temperature, solar radiation, and the tenperature of the local runoff. Stream Habitot: Consists of fuH 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 nJt dependent on mainstem conditions. Stream Mouth Habitat: Ex _tends from the uppermost point in the stream influenced by mains.tem Susitna Rher or slough backwater effects to the downstream extent of the stt·eam plume which extends into the mainstem Susitna River or slough. Upland Slough Habitat : Differs from side slough habitat in that the upstream end of the slough does not interc<~nect with the surface waters of the main channel Susitna River or it side channels even at high mainstem discharges. These slough! are characteri zed by the presence of beaver dams and an accumulction of silt covering the substrate resulting from the absence of mainstem scouring discharges .

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-1). 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, this site was probably used by more salmon than were counted. 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).

RM 71.6R Twelve 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 channel 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 small portions of this complex are vegetated, indicating frequent inundation by the mainstem. A survey conducted on September 25. 1984 fou nd seven redd sites and three dead ch um salmon. The number of redds indicates that the site was utilized by 'a greater number of salmon than " were observed. The R&M survey indicates an open lead in this area. No upwelling was observed in thi s site. No observed upwelling and the si t e being directly on the mainstem ind icates that th e open lead may be velocity related.

The open leads may be due to upwe lling 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 (Appendi x Figure A-9). The adjacent bank is high and steep with bank seepage present. Twenty three chum salmon and eleven 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 Cre ek Slough (Appendix Figure A-9). Peak counts of twelve chum 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-9). Bank seepage was observed during surveys of this site. A survey on October 9, 1984 observed nineteen redd and 41 chum salmon. Based on the number of redds and live fi s h observed this site is the third most important mainstem spawning location.

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 Septembe r 23 and October 2, 1984 observed 538 live chum salmon and 75 l ive coho salmon. Upwelling was observed extensively throughout this site. This was the major mainstem spawning s i te located. Rl1 95.0C A minor chum salmon spawning site was located at RM 95.0C (Appendix Fi gure A-12). A single chum reed with eggs and three live chum salmon were fo und in a pool behind a beaver dam. Part of this area is vegetated indicating some present stability. No evidence of upwe lling was observed. RM 95.2R This chtn salmon spawning site is located in Husher Slough (Appendix Figure A-12).

A350 Habitat parameters of channel width, depth and substrate components were measured in the interface reach of eighteen lower Susitna River streams located between RM 28.0 and 98.6 in 1984 (Figure B-1). These data were collected at two mainstem discharges as measured by U.S. Geological Survey at the Sunshine gaging station (RM 83.9) (Appendix Table E-1). This appendix presents those findings by stream and in addition, defines individual use of the stream interface r·eaches for adult salmon spawning and passage. Appendix Table B-1 summarizes the habitat and adult salmon use data for all lower Susitna River ~tream interfaces sampled in 1984. FISH CREEK (RM 31 .2 ) Interface Reach Habitat Description The interface reach of Fish Creek is up to 150 feet wide and ten feet deep high discharges, but the average width is less than 120 feet with average depths less than six feet (Appendix Table E-1). The primary substrate is silt-sand and the water is tannin stained (Figure B-2). At a Susitna River discharge of 43,320 cfs on August 14, 1984 there were no mainstem backwater effects observed in the stream. Susitna water was backed up into the stream interface approximately 30 feet at a mainstem discharge of 87,270 cfs on August 25. The Yentna River which influences th£ mouth of Kroto Slough below Fish· Creek may also have affected the backwater area observed. A351 -· .. 1 J I I I I I I I I I I I I I I I I I I I ----,· J -.....

LITTLE WILLOW CREEK (RM 50.5) Interface Reach Habitat Description The interface reach of Little Willow Creek is approximately 70 feet wide with depths less than 2.5 feet. At high discharges widths up to 90 feet and depths up to four feet w~re me.asured (Appendix Table E-1). Streambed substrates in this area are generally rubble and large gravel with intermittent pockets of si 1 t-sand (Appendix Figure B-7). Creek water is generally clear. At a mainstem discharge of 110,600 cfs on Auguc;t 26 the creek water was turbid so it was difficult to determine thE: extent of mainstem backwater effects. However, due to high creek flow we estimate they were minimal or nonexistant. A slough just below the mi'Juth carr ied mainstem water on both dates when habitat data was collected in interface reaches. Adult Salmon Use Pink salmon spawning was observed in the interface reach of •little Willow Creek in 1984 (Appendix Figure B-7).

Above the first third mile, the substrates become gravel to cobble size. At mainstem discharges of 42,780 (August 16, 1984) and 83,380 cfs (August 27) there were no mainstem backwater effects in the interface reach. Adult Salmon Use Salmon spawning did not occur in the interface reach of Rabideux Creek between July 21 and October 17, 1984. A cross-section transect revealed a streambed substrate composition mainly of silts with bedrock indicating unsuitable salmon spawning habitat (Appendix Figure B-14) (ADF&G, 1983b). The interface reach is a passage area for chinook, sockeye, pink, chum and coho saimon spawning in upstream habitats (Appendix Table D-1). SUNSHINE CREEK (RM 85 .1) Interface Reach Habitat Description Sunshine Cre~k is approximately 45 feet across and less than three feet deep in the mouth area with clear water (Appendix Table E-1). Streambed substrates are rubble-large gravel with up to three inches of silt in some areas (Appendix Figure B-15). The slough which Sunshine Creek enters carries mainstem water much of th@ time. At mainstem discharg~s of 42,780 cfs (August 16, 1984) and 83,380 cfs (August 17) there were no backwater effects in the interface reach .
