Data was collected regarding the spawning distribution and density of pink and chum salmon. Spawning sites were identified and mapped. The study sites were resurveyed on each river. Reference points were re-established, photographs were taken and line. drawings were made. The number and location of salmon spawning in the study sites were recorded. Evaluating inter-gravel survivals of pink and chum salmon eggs and/or fry, as it is affected by natural dewatering, is the basis of this study. Eggs were taken and planted in Terror River to establish site specific data on inter-gravel survivals. aetied MAP 1 KIZHUYAK Say 0 1008 3000 $000 Fa 0 300 300 1500 My Creek =n = = Figure 1 KIZHUYAK RIVER SYSTEM @ PRE-EMERGENT FRY SAMPLING SITES > INDICATES PRE-EMERGENT SAMPLING SITES NORMALLY DONE BY ADF&G @® Studv Sites Figure 2 TERROR RIVER SYSTEM @ PRE-EMERGENT FRY SAMPLING SITES ~ INDICATES PRE-EMERGENT SAMPLING SITES NORMALLY DONE BY ADF&G @ Study Sites METHODS Three transects were re-established across each study site. Each study site was approximately 200 feet long. Transects were previously marked with either 30-inch pieces of rebar or 60-inch steel fence post and marked with fluorescent red paint and engineers’ tape. Headstake elevations were determined by differential leveling, and a cross sectional profile was determined for each transect using a self-leveling level, rod, and tape. Stream bank distances between transects were also measured. Flow measurements were made with a Marsh McBirney electromagnetic current meter. Water temperatures were recorded with a hand held thermometer. Kizhuyak River Study Sites On August 23, 1990, the Kizhuyak River was surveyed by Greg Watchers, and Steve Honnold. Study Site #1 Study Site #1 was re-established slightly downstream of the USGS gage station and above the confluence of Watchout Creek (Figure 3). The water temperature was 10.0 degrees Celsius, and flows taken at "A" transect measured 104 CFS. The river bottom. material was composed of large cobble material. The west side of this study site is experiencing continued erosion as observed in March of 1990. Transect C has been lengthened to accommodate bank sloughing; stream bottom characteristics have changed along this transect (Figures 3a,b,c). The major spawning area in this location was in the margins of the stream near the bank on the west shore between A an B transects and shallow areas of the east shore along the entire study site (Figure 4). A total of 28 pinks and 2 chum salmon were observed. The best dewatered (March 1991) margin areas to check egg survivals will be between A and C transects along the east bank of the river. Figure 3.

Study Site #3 Study Site #3 is located slightly downstream from the confluence of the Watchout Creek (Figure 5). The water temperature was 8.0 degrees Celsius, and flows were measured at 365 CFS on transect A. Water levels were too high to measure C transect flows which had been measured in past surveys. Also, water conditions prevented transect C and B elevations from 165 to 180 and 155 to 180 from being delineated, respectively (Figure 5a,b,c). The river bottom in this area is very dynamic and has exhibited great change from survey to survey. The bottom is composed of gravel, cobble,. and fines. The west river bank exhibited significant erosion along the entire study site which was noted in August, 1989 and March, 1990. The west end of each transect was lengthened by approximately 50 feet to compensate for the bank sloughing. A total of 10 pink and 30 chum salmon were observed in this study site (Figure 6). The best areas to check egg survivals will be on the east side of the river along the entire study site. a Figure 5.

Terror River Study Sites On August 22, 1990, Terror River was surveyed by Greg Watchers and Steve Honnold. Study Site #4 Study Site #4 was re-established approximately 200 feet upstream from the confluence of Ouzel Creek (Figure 7). The water temperature was 9.0 degrees Celsius, and flows taken at transect "A" were 83 CFS. River bottom material is composed of gravel with some fines and silt present. Erosion was, again, noted on the south bank along the entire study site (Figures 7a,b,c). Transects C and B exhibited the most disturbance due to the erosion and were lengthened to compensate for bank sloughing. The north side of the study site between C and B transects continues to be dynamic (as was noted in September 1989 and March 1990) with C transect being lengthened to reach the north stream bank. Also, two small sand bars have developed, mid stream, near B transect. A total of 47 pinks and 4 chum salmon were observed in this study site (Figure 8). Also, 10 bear kills were observed in the area. Based on the spawning distribution, the best projected sites to study effects of dewatering are near the A and B transects at a south bank location. Egg plant plots will be evaluated at locations near the north river bank (see Egg Planting section). 417 Figure Terror River, Upstream Study Site #4, located above Ouzel Creek, August 22, 1990. = o( = DEPTH (FT) 18 L6 L4 12 0.8 0.6 0.4 0.2 -0.2 -0.4 -0.6 -0.8 -12 -L4 TERROR RIVER UPPER 8/22/90 TRANSECT 4A "WL eaNbTy t Tester tee T4S ‘TOATY AOIEL ‘yp JOesuer} We eTTjJord peq ue BEE EEUee IEEE EEE HA aS al eae EEE T I Guiman @reeiatistat HEL Tee EEE lf ql T 1 1 Vaeat 5 IS 25 95 45 55 65: 75 8 95 105 108 Ho 115 DISTANCE (FT) -oz - DEPTH (FT) TERROR RIVER UPPER 8/22/90 TRANSECT 4B 0 10 - 20 30 40 SO 60 70 80 90 100 HO 120 129 TT PT V DISTANCE (FT) —---- 130 “fo 134 140 “qs eammbtg *J@ATY TOIEL ‘gp Joesuez} Fe aTTyoid peq weer4s -1z- DEPTH (FT) TERROR RIVER UPPER 8/22/90 TRANSECT 4C °OL emnbtg Hae Ti See i Te ite ee eee ieee ie ee Ti 0 3 6 10 20 30 40 50 60 70 80 90 100 IID 120 130 140 150 160 170 175 180 190 196 DISTANCE (FT) *TOATY Joie], ‘Dp JOosuerz We eTTjord peq wee1r4s a d 10-12 eeiaks — Eo 1.6'to 2.3°— —_—_ _—_— depth of river varies between 10.4'& 1.0’ except for center stretoh / \ \ weak flow willow FIGURE 8. ‘Terror River, upstream station (4).

Total of 47 pinks, 4 chums and 10 bear kills were observed, Study Site #5 Study Site #5 was re-established at low tide in the intertidal area on August 22 (Figure 9). Water temperature was 10.0 degrees Celsius, and flows taken at transect "A" were at 155 CFS. The river bottom was composed of gravel to sand materials. Stream bed and bank erosion continues along the north bank of the river within the study area, but appears to be progressing slowly compared to other more dynamic study sites (Figures 9a,b,c). River bottom profile at transect C, however, has changed significantly. A total of 11 live and 3 dead pink salmon and 6 chum salmon were observed in the study area. Also, 20 redds were observed along the north side of the study site and 15 bear kills were found in this vicinity (Figure 10).

Egg Take and Egg Plant On August 30, 1990, approximately 30,000 pink salmon eggs were collected from the intertidal area of Terror River by Greg Watchers and Steve Honnold (Figure 13). These eggs were transported, after fertilization and water hardening, via a Jet Bell helicopter, to Pillar Creek Hatchery for incubation to the eyed egg stage. Eyed eggs were planted in Terror River study sites on October 13, 1990 by Steve Honnold and Pam H. Barker. At the eyed developmental stage, eggs are quite durable and not as susceptible to shock. The eggs were hydraulically pumped into the gravel by using a Homelite XLS 2 1/2 hp pump which forces an air and water mixture through a probe into the gravel, making an artificial redd, and depositing the eggs (Figure 14). A total of 24,300 eggs were planted in 81 egg plant plots with approximately 300 eggs each. Each plot was marked with a 12" plastic tent stake and surveyors tape (Figure 15). In addition, water depth was measured in each egg plant location using a depth gauge, and water temperature was recorded using a hand held thermometer. Eggs were planted in study site #4 along what was originally the north bank of the river (Figure 16). Forty egg plants were made at this site. At study site #5, the eggs were planted north of the gravel bar (Figure 17). Eleven egg plants were made at this site. Egg were not planted at study site #6 since the survivals were 0% for 1989 and 1990 when pre-emergent sampling was 4) i35|u 13. Terror River Pink Salmon Egg Take, August 22, 1990. Figure 14.

In addition to the eggs planted in the three study sites, 30 egg plants were made in the "control" site, upstream of study site #4 just below the dam (Figure 18). This area has no natural spawning due to a barrier falls. Figure bh oo Control site located at Terror River, above Barrier Falls, below dam, October 13, 1990. The site of 30 egg plants is circled. SUMMARY Spawning of pink and chum salmon appeared to be past peaking during the late August surveys in Terror River and at the peak in Kizhuyak River. Escapements of pink and chum salmon in 1990, in both rivers, were lower than usual and escapements in the study sites reflected these overall results. zr iv s Year Pink Chum Kizhuyak 1987 47,000 17,000 1988 38,910 27,500 1989 *240,000 55,000 1990 15,400 2,300 Terror 1987 72,000 15,000 1988 124,400 15,000 1989 *210,000 39,000 1990 59,600 5,000 Note: Data obtained from Commercial Fish Division, Alaska Department of Fish and Game, except *, which was an estimate made from data provided by Roger Blackett, RFB Aquatech Inc.

Bottom profiles at the intertidal Terror River study site changed even though bank erosion is slower here. Terror middle study site remains the most static. High water was a problem when surveying Kizhuyak River. Pink salmon eggs (30,000) were collected at Terror River and incubated to the eyed egg stage. Later, 24,300 eyed eggs were planted in 81 plots in three Terror River study sites. These plots will be evaluated in March, 1991 for inter-gravel survival in the event of possible dewatering in these areas.

These study sites were established in the fall of 1987. The primary focus of this field work was to monitor and evaluate the effects of de-watering on incubating pink and chum salmon eggs and fry and to, also, note and document any stream profile changes. The study sites were resurveyed, with reference points re- established, as well as photographic documentation undertaken at each site. Survival of salmon eggs and fry was documented at each site. METHODS Cross sectional profiles, flow measurements, and water temperatures were assessed following the same procedures and in the same locations as described in Par* I. Pre-emergent sampling was conducted at each study site. Wild and planted redds were sampled using a Homelite XLS 2-1/2-4A pump with attached probe, and a two foot diameter cylindrical shaped frame collection net (Figure 19). Fry and eggs were hydraulically pumped out of the gravel by forcing an air and water mixture through the probe which was manually worked into the stream bed. The collection net was placed on the stream bed and the probe was_ worked within the hoop of the net. Eggs and fry that were pumped out of the gravel were collected in the apex of the net as they moved with the flow of water. The contents of the net were emptied into a plastic dish pan for enumeration. Planted redds at Terror River Study sites as well as a control site, that remained marked with plastic stakes and surveyors tape from fall field work, were sampled. In addition, ten to twenty wild redds were sampled at Terror River study sites 4 and 6. Approximately, 20 wild redds were sampled at each Kizhuyak River study site. Figure 19. Pre-emergent sampling at Terror River, March, 1991. Kizhuyak River Study Sites Field work was conducted at Kizhuyak study sites on March 29 and April 12, 1991 by Tim Ward and Steve Honnold. A Jet Bell Helicopter was used to move from site to site. Study Site #1 Study Site #1 is located slightly downstream of the USGS gage station and above the confluence of Watchout Creek (Figure 20). The water temperature was 6 degrees C and stream flow at transect C was 120 CFS when measured on April 12. This study site is experiencing erosion at the west river bank at transect A, however, the other transects have remained fairly stable (Figures 20a,b,c). Beaver activity is noticeable and may be influencing erosion and stream bottom changes. Pre-emergent sampling of 25 wild redds, in 3 locations, was undertaken at this site on March 29 (Figure 21). Ten near the east bank between B and C transects, 10 near the east bank between A and B transects, and 5 near the west bank near C transect. A total of 6 live silver salmon eggs were found (Table 1). Eggs found were strongly eyed. Water temperature was 3.5 degrees C. Figure 20. Kizhuyak River, Upstream Study Site #1, located near USGS gage, March 29, 1991.

The water temperature was 2 degrees C and stream flows were measured at 52 CFS at transect "C" on March 29. The west side of the study site remains very dynamic with erosion occurring (Figure 24). Beaver activity is obvious and is enhancing the erosion and sloughing of the bank, as well as influencing the river bottom profile (Figures 22a,b,c). Pre-emergent sampling of 20 wild redds was undertaken at this site on March 29 (Figure 23). Twenty sites were pumped on the east side of the study site between A and B, and B and C transects._ High water and bank erosion prevented sampling of the west side at A transect as was originally planned. A total of four live chum salmon fry, 1 dead chum salmon egg, and 1 dead Dolly varden char fry were collected in this study site (Table 2). Live fry found were 90% buttoned up. Water temperature was 2 degrees C. ~ TA _ Figure 22. Kizhuyak River, Middle Study Site #3, located below the confluence of Watchout Creek, March 29, 1991.

A Jet Bell Helicopter was used to move from site to site. Study Site #4 Study Site #4 is located approximately 200 feet upstream from Ouzel Creek (Figure 25). The water temperature was 4 degrees C and stream flows measured at "A" transect were 56 CFS on April 12. This site remains dynamic with more small log jams and sand bars developing (Figures 25a,b,c). A total of 38 of the 40 egg plots planted the fall of 1990, and 10 wild redds were sampled for pre-emergent data in this site on March 27 and 29th (Figure 26). Two egg plant plots were not located due to marker stakes being missing. Planted redds were sampled along the north side of the study site in two locations, one near transect A and one near transect B. Wild redds were sampled on the south side of the study area between B and C transects. Planted redds resulted in 24 dead pink salmon eggs (Table 3). The water depths of planted redds sampled near A transect were 0.3 to 0.5 feet shallower than the water depth at the time of planting (Figure 27). This may indicate that de-watering may have been a factor in finding only dead eggs in this location.

The absence of a large number of dead eggs in these plots and the small number of missing markers may indicate that fry emergence had occurred prior to sampling. Survival in 1990, in planted plots, along transect A was poor and obvious de-watering effects were recorded, while transect B plots had better survival with little de-watering effects observed. 1991 results may be attributed to de-watering and/or early emergence. Early emergence would most likely have also resulted in as high a mortality as de-watering or scouring since environmental conditions at this time period are poorly suited to fry survival (Brennan, personal communication). Wild redds resulted in 30 live chum salmon fry and 6 dead pink salmon eggs. Live fry collected were approximately 90% buttoned up. Water temperature was 4 degrees C on March 27, and 0.5 degrees C on March 29.

The area was surveyed at low tide on April 12. The water temperature was 3 degrees C and stream flows were 131 CFS at "A" transect. The north bank of the study area continues to erode slowly (Figures 28a,b,c). The rebar, however, remains in place from last summer. Little flowing water remains between the south bank and the gravel bar, along the study area. The tide began to advance while completing elevations at B transect and during measurements at C transect. A total of 9 of 11 egg plots planted last fall were sampled for pre-emergent data in this site on March 27 (Figure 29). The aoe remaining egg plant plots were not located due to marker stakes being missing. The planted redds sampled were north of the gravel bar, near transect B. Wild redds were not sampled due to high water in the location of August redd sites. Planted redds resulted in 366 live pink salmon fry, and 12 dead pink salmon eggs (Table 4). Planted redds were all at 0.0 feet sampling depth, but intergravel flows appeared good, resulting in an average survival of 14%. Live fry collected were approximately 90% buttoned up.

The water temperature was 2.5 degrees C and stream flows were measured at 133 CFS at transect "A" on April 12. This study area, generally, remains static as far as erosion and stream bank sloughing and all rebar and stakes were intact (Figures 30a,b,c). However, along transect C on the northeast side of river some channel shifting has occurred due to some debris build-up (Figure 32). A total of 20 wild redds were sampled for pre-emergent data in this site on March 27 (Figure 31). Wild redds were sampled along the northeast side of the river near C transect and the southwest side between B and C transects. Wild redds resulted in 237 dead pink salmon eggs and 9 live freshwater sculpin (Table 5). This area has had similar results in 1989 and 1990 and appears to have a survival problem which could possibly be attributed to freeze out or impact due to de-watering.

This site was selected since it was above the barrier falls, just below the dam, and would prevent any wild salmon spawning in the area. Therefore, only planted redds would incubate in the gravel and an indication of planting survival could be attained. A total of 30 egg plots planted last fall were sampled for pre-emergent data in this site on March 29. All marker stakes were intact at this site. Planted redds resulted in 7 live pink salmon fry, 1 live Dolly Varden fry and 33 dead pink salmon eggs (Table 6). Flows were strong here and large rocks prevented a good seal on the stream bed with the collection net, so a lot of eggs and fry may have not been collected for enumeration. Thus, data collected may be conservative. Live fry collected were approximately 90% buttoned up.

Forty-one samples did not contain any fry or eggs. Four samples contained fry or eggs, of which, 2 were located in the upper study site near the USGS gage station, and 2 were located in the middle study site downstream from the confluence of Watchout Creek. The two samples that contained live fry or eggs at the upper site were located on the west side of the stream and were composed of eyed silver salmon eggs. No dead eggs or fry were found at the upper site. The east side samples revealed no eggs or fry in 1991. In 1988, the majority of live. eggs or fry were found on the east side of the stream with no dead eggs or fry found. In 1989 and 1990, the live fry and eggs were found on both east and west sides and in mid point samples, with dead fry or eggs found on the east side samples for both years. The two samples in 1991 that contained live fry and dead eggs at the middle site were on the east stream side (west side was not sampled). In 1988 and 1990, live fry or eggs were only found on the west side samples with no live or dead fry or eggs found on the east side. In 1989, no live or dead fry or eggs were found at the middle site. 1991 pre-emergent results may be due to low escapements for both pink and chum salmon in 1990 (Brennan, personal communication). Terror River was sampled for pre-emergent data at 3 study sites for a total of 47 planted and 30 wild samples. An additional 30 planted sites were sampled at a control site. Thirteen planted samples and 23 wild samples contained fry or eggs. Eleven of the control samples contained fry or eggs. Water levels at transect A, of the upper site, plant sites locations were from 0.3 to 0.5 feet lower when sampled then when planted. Both upper site plant areas experienced little wash out of marker stakes. The plant sites that were sampled contained few dead eggs or fry and no live eggs or fry and may indicate early emergence since plots did not appear to wash out. At the intertidal study site, scouring of wild redds may have occurred on the north side of the stream. Average survival of egg plants sampled at the intertidal site was 14%. The middle site, downstream of the USGS cable crossing experienced high. egg mortality. Poor gravel and low flows may be a factor on the northeast sampling location and freeze out and de-watering on the southwest location at this site. Middle site results were similar in 1988, 1989, and 1990. Table 7 compares dewatered and non dewatered egg plant plots at Terror River study sites for 1990 and 1991. The 1991 pre-emergent results at Terror River may indicate early emergence, de-watering and scouring caused mortality in upper areas. Brennan (personal communication) indicated that high water events (scouring) caused mortality in upper Terror River which effected Commercial Fish Division sampling in these areas (Table 8). The intertidal area appeared to have good survival and, again, these results paralleled Commercial Fish Division results. Table 7.
