INTRODUCTION This initial Aquatic Habitat and InstreafTI Flow (AH) report is one of a series of subject reports representing first stage data reduction o f Phase I (July 1, 1980-0ctober 31, 1981) fisheries and habitat infonnation collected by the Alaska Department of Fish and Game (AD F&G ) Susitna Hydroelectric (S u-Hydro ) Aquatic Studies Program. Information from this and the other Phase I subject reports (Adult Anadromous, AA; Fishery and Resident and Juvenile Anadromous Fishery, RJ, reports) will be synthesized and integrated into a Ph ase I Final Report. The Phase 1 Final Report wi11 be forthcoming in February 1982 and will present the rel ationships drawn from the respective AOF&G subj ect reports above and reports of others containing information relevant to the assessment of the proposed Susitna Hydroelectric project impacts on fisheries. Realizing the need for these habitat data by Acree; American and its various subcontractors to enable them to meet their respective report deadlines, portions of the data contained herein were previously d i stributed up on request in preliminary form. Existing information on the fishery resou rces and aquatic habitat within the Susitna River drainage ranges from the most fundamental and general i zed to localized and specific data on speci es managed by the Department in areas where competition for these species is keen . It should be noted, however, that information on all species in the Susitna River drainage, even those studied in greatest detail, is still largely preliminary. Moreover, data on a1 1 species present i n the area, including data on their interrelationships -1- DRAFT • with other species and with their physi'lchemica l surroundings are essential for determining the impacts of the proposed Su Hydro dams on the fishery • • resources. Prior to the initiation of the Phase I Su Hydro Aquatic Study Program, the ADF&G collected basel i ne data on fisheries and habitat between 1974 and 1977 (ADF&G 1974, 1976, 1977, 1978 ) to enable the AOF&G to design the necessary studies for determining the impacts of this proposed project on the fishery resources. The initial comprehensive five year Plan of Study was submitted to the Alaska Power Authority (APA) in 1978. However, studies were not imple- mented because funding was unava1 lable. In September 1979, the ADF&G agreed to update and revise the 1978 Plan of Study, submitting it to the APA in No ·1ent>er 1979 (ADF&G 1979). The APA provided funding to the ADF&G under a reint>ursable sources agreement to initiate this first year of the five year Phase I/II studies in July 1980. The Sus i tna River {Figure 1) is approximately 275 miles long from its sources in the Alaska Mountain Range to its point of discharge into Cook Inlet . Its drainage encompasses an area of 19,400 square miles. The mainstem and major I tributaries of the Susitna Rtver, including the Chulitna, Talkeetna and Yentna Rivers, originate in glaciers and carry a heavy load of glacial flour during the ice-free months. There are also many smaller tributaries which are perennially ice-free. The Susitna River and the major rivers entering Knik Arm represent approximdtely ?0-801 of the total freshwater entering Cook Inlet (Rosenberg et al. 1967) • -2- • • Figure 1. • , I , , " , ,.---- / ', I ' I I I I I I I I , " " ---- ;' " " -"' Susitna River drainage . -3- I I " I """"---""' ,..,-__ .,., ,..---' I .... I I I I I I I I I I I I \ ' ' ' f I I / DAAFT The proposed Susitna hydroelectric project will have various impacts O'l the aquatic environments of the Susitna River . The majority of the impacts on fish species will likely result from changes in the natural regimes of the river rather than direct impacts on the fish in the vicinity of the proposed dams. Primary areas of concern are modification of seasonal instream flows,* increased turbidity levels during winter months, and variation of thermal and chemical parameters. Preliminary stud ~es indicate that alterations of the habitat may adversely affect the existing fish populations and render portions of the drainage either non-productive or unavailable in future years (ADF&G 1978; 1979). Continuously movi ng water, or current, is the distinguishing physical habitat feature of the Susitna River and its tributaries. Instream flows influence various physical and chemical param@'ters and biological organisms to create particular aquatic environments in the Susitna River Basin. These include volume, velocity, temporal variation of flows, channel morphology (size, shape, gradient, and geologic material of channel), water quality (tempera- ture, turbidity, dissolved gases, etc.), and stream load (bed load, suspended 30lids, and other materials, such as watershed inputs, in transport). Analogous chains of events follow any alterations of instream flow. The altered stream will attempt to establish new equilibrium conditions; and this dynamic process may lead to substantial changes in channel shape, wetted area, substrate characteristics, water qual'ity, etc. Moreover, these changes may be felt as far downstream from the proposed dams as Cook Inlet (Bishop 1975). * The flow of water which appears in the Susitna River at a given time con- stitutes the "instream flow". -4- DRAFT It is important to remember that the complexity of the physical interactions outlined above is compounded by the fact that natural flows fluctuate with seasonal and climatic variations. As a ,·~sult, impacts produced by the proposed dams will stem not only from the amount of flow modification but also from the timina of the modification in relationship to nonnal seasonal flow fluctuations. Reduction, elimination, or rescheduling of naturally recurring high flows can have serious consequences on channel characteristics. An increase in flow can also induce profound changes in the lotic environment during naturally occurring low flows. The physic~l conditions and interactions within the Susitna River Basin discussed above, provide essential habitats for aquatic, riparian, and other organisms. As a result, any alteration in the physical environment also affects the associated biological populations. Although the emphasis of this and related reports will be to detenmine the impacts of instream flow changes on the Susitna fisheries, it should be apparent that instream flows can exert similar profound effects on other aquatic organisms, as well as on riparian and terrestrial wildlife, navigation and other instream flow re1ated uses (Erickson 1977; Stalnaker and Arnette 1976; Hinz 1977; Newei 1 19i7; Martin 1977; Klarich and Thomas 1977· Judy and Gore 1978; MDFWP 1980; White et al. 1981; American Fi5heries Society and American Society of Civil Engineers 1976a, b; Townsend 1975). lnstream flow may, therefore, be considered one of the most essential deter- minants of aquatic habitat and hence fisheries productivity. Modifications of naturally occurring seasonal instream flows will produce a variety of changes -5- DRAFT in essential fishery habitat areas such as spa wni ng , i~'~cubation , rearing, overw intering, and passage hab itats . Decreased flows in the spring and summer can for exampl e lead t o silt depositio n, oxygen r edu ction in gr avel redd s , dewater ing of sloughs , and may, r esult in suffoc ation of i ncubating eggs and pre-emergent fry. Increas ed fl ows in the winter can wash away spawn ing substrate or destroy sheltering area s. Decreases and increa ses in flows which alter stream productivity will modify food availability in rearing and over - wintering habitats. In addition to modifying essent ial habitats, alterations to the Sus itna flow reg~mes can affect t he seasona l beha vior of fish species. Hyn es {1970) dis - cusses the importa nt i nte rrel ationships between seasonal flow r eg imes, fish movement, an d human al terat ion s of lotic environment. The complex i nter- relation ~h ip between i nstream flows and seasonal behavior of fish s pe cies i s compoun deo by the fa ct that seasonal variat ions in flows required by par- ticular spec ies may have to be quite large . Returning salmon species for exa mple may ne~d 30-50 percent of the mea n ann ual flow to ascend t he lower and middle reaches of a river system , and even more flow to ascend t he headwa te rs (Hynes 1970). As a result , the protection of fisheries resources requires not only that certain volumes of i nstream flow be maintained, but also that specific flows be available at particular times of the year. In sunmary, seasonal fluctuations i n the physiochemical comp os ition of the aquatic habitat are apparent ly the major factors influenc ing distribution of fish within the dra i nage. Any alterations resulting from t he propos ed hydro- -6- l • • DRAFI electric related project act iv iti es which will restrict or reduce quality or qua ntity of required habitat wil l aiso reduce fish populations and associated mem bers of the aquatic community • -7- • • • DRAFT VJ. OBJECTIVES To insure adequate information is available to determine the impacts of the proposed hydroelectric project and to design proper mitigative strategies, a two-phase five year data collection program has been developed . The following objectives were addressed in the Phase I ADF&G Aquatic studies (June 1981 -October 1981) of the open water field season: The study program was separated into three sections: AA, RJ, and AH. OBJECTIVE 1. Task 1.1 Task 1.2 Task 1.3 Task 1.4 OBJECTIVE 2. Determine the seasonal distribution and relative abundance of adult an~dromous fish populations produced within the study area (Figure 2). Enumerate and characterize the runs of the adult anadromous fish. Determine the timing and nature of migration, milling and spawn i ng activities. Identify spawning locations within the study area (ie.e, subreaches of the mainstem sloughs and side channels, tributary confluences, lakes and ponds, etc.) and estimate their comparative importance. Identify and determine methods, means and the feasi- bil ity of estimating the Susitna River's contribution to the Cook Inlet commercial fishery.

Therefore, these objectives cannot be addressed in detail until relevant data from the other ADF&G rep orts and other cooperators are inte- grated with these data in the February 1982 report . -11- 1 ' DRAFT VII. STUDY DESCRIPTION AND RATIONALE Phase I of the Aquatic Habitat and Instream Flow Study {AH) was subdivided into two segments (Figu re 3 ): 1) fishery habitat evaluations of the principal resident fish, and juvenile and adult anadromous salmon sampling areas to include point specifi c and general habitat evaluations; and 2) selected habitat evaluations which represent similar habitats in the study area in addition to those slated for fish sampling. A. FI SHERY HABITAT EVAL UATIONS Fishery habitat evaluation studies were performed during the winter and summer tield seasons and were subdivided i nto point specific and general habitat evaluations \Fi gure 4), Data wer~ collected by 15 biologists from the AH and RJ projects assigned to five joint crews, four i n the lower river and one in the upper river. Crews in the lower river were based i n semi-permanent tent camps located at the Yentn a, Sunshine and Talkeetna AA fishwheel sites and at Gold Creek . Eac h crew was self contained and utilized a pickup truck, out- board jet powered riverboat and helicopter for logistical support. The upper river crew utilized a truck, helicopter, fixed wing aircraft and r iver rafts for logisticll support. Mobile camps were set up and disassembled at each camp site each sampling period. 1.

SELECTED HABITAT EVALUATION The Selected habitat evaluation program was designed to evaluate the re l ation- shi ps of mainstem hydraulic and water quality conditions to fisheries habitat i n slough areas between Ta l keetna and Devil Canyon. The study was divided into two segments: (1) water quality and discharge data collection and (2) surveying and discharge measurements. The water quality and discharge measurement data were collected on a coopera- tive basis with the U.S. Geological Survey (USGS). One crew of three AH bi ologists and one USGS water quality specialist ope rated out of the four semi-pennanent lowe r river camps discussed previously. Logistical support was pro vided by train, f ixed wing aircraft, helicopter, picku p truck and an inboard jet boat. These data were collected to characterize ranges of water quality parameters (Table 2) and discharge within the five selected habitat evaluation study sloughs. The sa mpling was co nducted co ncurrently with the USGS's routine sampling Lf the mainstem Susitna River at bO ld Creek in order to allow compa r isons of th e water quality parameters between the various sloughs and the mainstem. Sampl~ were obtained three times, on e ti me per seasonal low, medium, and high flows. Two additional sampling tri ps with the USGS are scheduled for the winter of 1981-82, to characterize l ow flow winter conditions. · -15- Table 2.

In addition, the relationship between intra - gravel and surface water temperatures were evaluated at one slough through the use of thermographs . -19- ' DRAFT VIII. STUDY APPROACH A. GENERAL HABITAT EVALUATION 1. Methods* a. Physiochemical Dissolved oxygen, water and air temperature, pH, turbidity, stage and specific conductance were measured twice monthly at each general habitat evaluation study site, except in the Impoundment reach, where these parameters were measured monthly. Data were collected by a joint crew of Aquatic Habitat/Resident and Juvenile biologists utilizing customized riverboats as the primary means of transportation. Dissolved oxygen, water temperature, pH and specific conductance were measured with a Hydrolab model 4041. Calibration of the meter was performed immediately prior to departing for and returning from each sampling period and whenever else deemed ne:essary. Turbidity samples were collected and stored in 500 ml poly bottles in a cool and dark location until analysis. The turbidity samples were analyzed using a Hach model 2100A turbidity meter. Turbidity samples were analysed directly from the sample bottles. No filtration or dilution methods were used. Water temperatures were continually recorded at several sites using Ryan Model J, 90 day thermographs. Stage data were collected by insta l ling staff gages at each general habitat evaluation study site and AA fishwheel and sonar sites, and * Specific methods are presented in Appendix G. -20- DRAFT reading each gage twice monthly . Stage data were not collected for the Impoundment reach. Substrate was categorized as shown in Table 3. Point velocity measurements were taken with either Marsh-McBirney Model 201 portable water current meters, Price AA or pygmy flow meters using standard methods outlined by the manufacturer. Table 2.

Eight to thirteen representative general habitat -evaluation study sites were selected for general habitat evaluation and resident and j uvenile f isheries studies in each of the five study reaches. Point specific and general habitat data were collected a t each of these sites. Data were also collected at the AA sonar and fish wheel sites, identified spawning sites and special study areas. L Findings a. Habitat Descriptions of Each General Habitat Evaluation Study Site by River Reach. Representative general habitat evaluation study sites were sampled twice monthly to characterize their physiochemical parameters. A brief habitat description of each general habitat evaluation study site, grouped by river -27- DRAFT ~ reach, is presented below. Planimetric maps of each general habitat evaluation study site are presented in Appendix A. i. Ventna Reach ll) General description. The Ventna reach (Figure 5) extends from Fish Creek (R.M. 7 .0) to Little Wil low Creek (R.M. 50.5) on the Susitna River. There are 13 general habitat evaluation study sites in the Ventna reach including: Study Site River Mile Geographic Code Fis h Creek 7.0 15N/07W/27/AAC Alexander Creek Site A 10.1 15N/07W/06/DCA Site B -2.0 Miles Upriver 16N /07W/32/CCB Site C -4.0 Miles Upriver 16N/07W/30/ACD Anderson Creek 23.8 17N/07W/29/DDD Kroto Slough Mouth 30.1 17N/07W/01/DBC Mainstem Slough 31.0 17N/06W/05/CAB Mid-Kroto Slough 36.3 18N/06W/16/BBC Deshka River Site A 40.6 19N/06W/35/BOA Site B -1.0 Miles Upriver 19N/06W/26/BCB Site C -3.5 Miles Upriver 19N /06 W/14 /BCA Lower Delta Islands 44.0 19N/05W/l9/ACB Little Willow Creek 50.5 20N/OSW/27/AAD The geomorphology of the Susitna River varies in this reach. The Susitna River above the confluence with the Ventna River forms a bra;ded channel. Below the Ventna River, the Susitna River forms a single meandering channel to -28- DRAFT the head of Bell island. At Bell Island, the Susitna River separates into two braided channels and remains divided to the inlet. During all but the periods of highest discharge, there are large sand and silt bars and log jams present. The overall gradient for the reach is approximately 1 ft./mile (corresponding to a drop of 50 feet in elevation in 43.5 mil es }. The surrounding area is l ow in relief with meadows, muskeg and cottonwood present. The typ ical substrate is silt and sand. The Alexander and Deshka Rivers are heavily fished during the chinook and coho salmon seasons. Many year round and seasonal homesites are located on these systems. The on l y residents on the mainstem Susitna River are near Susitna Station (R.M. 25.4). The mainstem Susitna River is utilized primarily for access to other areas of the river 's drainage. Fish Creek (2) Hc:bitat desc ri ptions of general habitat loca - tions i n the Yentna Reach . The study site (Ap pendi x A, Figure 1} is located at the confluence of Fish Creek with the east channel of the mainstem Susitna River. Fish Cre ek is a relatively narrow meandering muskeg -i nfluenced creek whi ch carries a heavy silt load in spring. Depths in the study area vary from 2 feet to over 8 feet near the confluence. A small lake outlet enters the lower portion of the study area . Typic al substrate in the study area is silt. Cove r is provided -29- • • DRAFT by cutbanks, riparian vegetation and high turbidity during tne spring runoff . This general habitat evaluation study site was eliminated after one sampling period due to logistical reasons. Alexander Creek Alexander Creek, a relatively shallow, meandering muskeg influenced stream, is located at river mile 10.1. There are three separate general habitat evalu- ation study sites located on th is creek . Site A Site A (Appendix A, Figure 2) is located at the high water confluer.ce of Alexander Creek with the west channel of the mainstem Susitna River {R.M . 10.1). The creek at this site is relatively deep and wide with a uniform c r oss section . The Susitna River i nterface extends upstream app ro ximately 1/4 the length of the study site. The substrate was predom ~nately composed of s11t througho ut the sampling season. The west bank is a relatively high cutbank with fallen trees providing co ver. The east bank is s loping with alder and will ow providing cover under high discharge conditions. Site B Site B (Appendix A, Figure 3) on Alexander Creek is located 2.0 miles upstream of the confluence . The creek in t he study area is relatively shall ow, with substrate consisting of silt and mud. The creek splitr. into two -30- • • • URA FT channels separated by a low mud island with grasses present. Under hi!Jh discharge conditions, overhanging and fallen trees provided cover alo1g sloping banks. Site C Site! C (Appendix A, Figure 4} on Alexander Creek is located 4.0 mi"1es upstream of the ~onfl uence. During periods of high discharge, the creek in this study site was relatively deep (3-5 f eet). Under these conditions, a deep pool formed on the west bank of t he lower portio·n of the study site. Banks were both sloping and cut. Typical substrate consisted of mud, sand and gravel. A small cleantater tributary, Granite Creek, entered the study at·ea. Under high d ischarge conditions, Granite Creek deposited a delta of sand and gravel extending across 3/4 of Alexander Creek. Cover is provided by over- hanging vegetation and submerged grasses. Anderson Creek The study site (Appendix A, Figure 5) is located at the confluence llf Anderson Creek a nd the Sus i tna River. The geomorpho 1 ogy and the phys 1 c•- chemistry of this site is greatly i nfluenced by the St~.iitna River. The creek mouth varies from 15 feet to 40 feet in width and is approximately six feet 11 depth under high discharge conditions. The width was reduced to approximatel!' five feet as the discha rge drt)pped. Under high discharge conditions, wher the flow of the creek was ~.:eked up by the Susitna River, velocities i n the study site were low (0-0.2 ft./sec.) and turbidities were high. As the discharge dropped and the influence of the Susitna River lessened, velocities -31- - URAFT increased slightly and turbidities dropped. The substrate and sloping banks consisted almost entirely of silt. During periods of high discharge, cover is provided by overhanging alder. Kroto Slough Mouth The study site {Ap pendi x , Figure 6) is located at the confluence of Kroto Slough and the Yentna River, approximately 2.0 miles upriver from the con- fluence of the Yentna River with the mainstem Susitna River (R .M. 30.1). The major influence on the slough in the study area ultimately depends on the stage at the mi d-Krot'l S 1 ough fork. Under 1 ow discharge conditions, the majority of the flow frorr. upper Kroto ~lough is diverted i nto the Susitna River. As a result, the primary influence of the slough at the mouth becomes dependent on tributaries that enter the slough below the fork. Under high discharge conditions, the upper Kroto Slough flow is not entirely diverted, causing the influencE of the slough at the mouth to be a mixture of the two water sources. The slough in the study a rea is relatively shallow and mean- dering. The width of the study area is approximate1y 200 feet with depths varying depending on discharge. The north s ·ide of the study site consists of a low cutbank and a large silt bar (50 -1 00 feet in length). The south side consists of a higher cutbank (S-8 feet) with no bars present unt~l very low di scharges . The substrate consists entirely of silt. Under high discharge conditions. when the banks were flooded, cover was provided b¥ overhanging willow and alder. Overall the site was reli'.tively stable, with the most significant variable being water level fluctuation. -32- DI<AFT Ma i nstem Slough The study site (Appendix A, Figure 7) is located in a side channel slough of the Susitna River. The site has two different habitat types. The lower portion of the study site consists of a large back eddy (approximately 200 x 1000 feet) characterized by low velocities, silt deposits and depths ranging from 3 to 10 feet. Cover is provided by a debris jam at the lower end of the site and vegeta t ion aTong sloping banks. The slough in the upper portion of the study site by contrast is relatively narrow, shallow, and fast running. Substrate i s typified by rubble . Under low discharge conditions, current in the lower portion of the study site increased, el i minating the back eddy. Mid-Kroto Slough The study site {Appendix A, Figure 8) is located where Kroto Slough forks at river mile 36.3 of the Susitna River. The majority of the flow returns via a fork to the Susitna River. Under low discharge conditions, sand bars appeared in the vicinity of the fork. These sand bars diverted an even greater percentage of the discharge into the Susitna River, ~ausing the downstream portion of the slough to be influenced primarily by tributaries. The s lough at the study site is fairly wide (100-200 feet) and fast running. Substrate is predominately silt with sand and gravel present i n the vicinity of the fork. There is a four foot silt cutbank on the east side of the slough. The bank on the southwest side varies from 2-8 feet in height and has not been eroded recently. During peri ods of high discharge, cover is provided by bank vegetation a nd debris. -33- • • • DRAFT Ueshka River The Oeshka River (Kroto Creek ) is a rela t ivel :' shallow, meandering river influenced by adjacent muskeg nabitats. There are three separate general habitat evaluation study sites located on the Deshka River. Site A Site A (Appendix A, Figure 9) is located at the confluence of the Oeshka River with the mainstem Susitna River. The study site geomorphology and physiochemistry is heav i ly infl uenced directly by the mainstem Susitna River and indirectly through a small slough that enters the study area on the east bank of the Oeshka River during periods of high discharge. The river in the study site is relatively wide and deep with the substrate consisling almost entirely of silt. Gear placement was along the west bank, which is steep an !1 wooded with many recreational cabins and small floating docks present. During periods of high discharge, cover was provided by overhanging vegetation. Site B Site B (Appendix A, Figure 10) on the Deshka River is located 1.0 mile upriver from the confluence. The river in the study site is relatively shallow and meandering. The channel substrate is silt, with rubble present in several areas of the banks. Gear placement is a long the west bank which is steep and wooded. Ve getation provided cover under high discharge conditions. A year round homesite is located on the east bank. I -34 - • • • DKAFT Site C Site C (Appe ndi x A, Figure 11) on the Deshka River is lonted 3.5 miles upriver from the confl uence. The river in the study site is relatively shallow and narrow. Und~r low discharge con dit ions, riffles developed on the east side of the channel. Several holes are present on the west side of the channe 1. Cover is provided a 1 ong s 1 oping banks by debris and overhanging vegetation. Substrate consisted of sand, silt and gravel . Lower Delta Islands The mainstem study site (Appendix A, Figure 12) is located at the down- stream side of the Delta Islands , at the confluence of center channel with the mainstem Susitna River. The river from the west bank to mid-channel is relatively wide, deep and fast flowing . There is a large debris jam present on the west bank. The river in the vicinity of the east bank is relatively shallow and characterized by low velocities. A deep back eddy pool exists at the confluence . The west J a nk is sloping with overhanging vegeta ti on pro- viding cover. The east bank consists of a silt bar: The channel substrate consists almost entirely of silt. Aside from water level fluctuations, the site was relativ2ly stable. The site was eliminated in mid -August for safety reasons . -35- • • • DRAFT Little Willow Creek The study site (Appendix A, Figure 13 ) is located at the confluence of Little Willow Creek with an east bank slough of the Susitna River (R.M. 50 .5). The creek in the study area is a narrow {approximately 30' wide), meandering clearwater stream, containing a relatively deep pool. Un der high di :charge conditions, the substrate consisted almost entirely of silt. Unde r low discharge corditions, wh en the flow of the creek was no longer backed up by the slough, velocities in the crePk i ncreased and the silt substrate was rep laced by sand. Cover is provided along sloping banks by debr is and over- hanging wil}ows. ii. Sunshine Reach (1) General description. The Sunshine reach (Fi gure 6} of the Sus itna River extends from Rustic Wilder- ness (R.M. 58.1) to the Parks Highway Bridge (R.M. 83.5). Ten gener~l habitat evaluation study sites were located within this reach. The Rdbideux Creek site wa~ eliminated due to logistical difficulties and establishment of sites in four other tributaries of this reach. River miles and geographic codes of the each study sites are presented below : -36- • DRAFT Study Site River Mile Geographic Code Rustic Wilderness 58.1 21N /O£'.ti /25 /CBD Kashwi tna River 61.0 21N /05W /13 /AAA Caswell Creek 63.0 21N /04W /06/800 Slough West Bank 65.6 22N /05W/27 /ADC Sheep Creek Slough Mouth 66.1 22N /04W/30/BAB Goose Creek 1 72.0 23N/04W/31/BBC Goose Creek 2 73.1 23N/04W/30/BBB Main stem West Bank 74.4 23N/05W/13/CCA Montana Creek 77 .0 23N/04W/07/ABA Rabideux Creek 83.1 24N/05W /16/ADC The reach v~r ·es in elevation from approximately 125 to 275 feet above mean sea level and has an approximate gradient of 5.9 ft./mile (corresponding to a 150 foot drop in elevation over 25.4 river miles ). Thh reach lies between • the foothi lis of the Talkeetna ~·ountains on the east and the marshy area be1ow the Alaska Range on the west. The river i n the lower two thirds of this reach is extensively b ~aided with fo rested islands and non-forested bars between the • braids of the chan nel . The upper third of the reach narrows and the braiding reduces until at the Parks Highway Bridge there is one chan nel. Above the bridge the river begins to braid again. The Sunshine reach is the most accessible of the five study reaches. All of the sites on the east side of t he rivl·r are accessible by the present road system. These r oads are a comb i nat i on of public and private and are either paved, gravel or f our wheel dri ve trails. The sites on the west side are access i ble or.ly by boat, helicopter and /or snow mach i ne . -37- • • • DRAFT There are several homesites along this part of the river. The tributaries enterin3 from the east are popular salmon fishing areas with chinook taken in the mid-sunmer and coho in the early fall. There is potential for future agricultural development in this region. Very 1 ittle hunting pressure was observed. Recreational boating was associated with salmon fishing. Rustic Wilderness (2) Habitat Descriptions of General Habitat Study locations in the Sunshine Reach. The R~stic Wilderness study site (Appendix A, Figure 14) is located in an east bank side channel of the Susitna River . lt is located adjacent to a real estate development of the same name. The dominant vegetation at this site is spruce -birch forest with alder and willow present where the soil has been dis- turbed. At high water, 60-70: of the shoreline is densely vegetated. Sub- strate could not be detennined due to high turbi dity. The site was in a stable area, with no change in habitat noted except the rise and fall of water levels . Kashwitna River The Kashwitna River study site (Appendix A, Figure 15) is located three miles upstream from Rustic Wilderness, on the east bank of the Susitna River . The Kashwitna River is a fast flowing, relatively stable meandering glacial stream. The study site is located at the confluence of the stream with the main s tem Susitna River. Under high discharges, the mouth of the stream -38- • • • DRAFT divides into two channels separated by a gravel bar and an island. Only the channel present during low discharges wa s sampled on a routine basis. Large deposits of light colored, granular Sdnd were observed deposited at the mouth of a slough at the upper end of the site and on the bottom half of the gravel bar separating the high water channels. The channel that was present only during periods of high discharges had bottom substrate of this same sand. uuring periods of relatively high velocity, parts of the site maintained the same deposits of large debris throughout the season, providing sources ot cover. Turbidity and overhanging riparian vegetation also provide sources ot cover. Logs are embedded into the bank of the south side of the is land. These logs protrude into the main ch~nnel providing c ~v er. Caswell Creek This study site (Appendix A, Figure 16) is located on the east bank of the Susitna River at the confluence of Caswell Creek with the mainstem Susitna River. The water in this creek is of l ake and muskeg origin, resulting in its brown appea ranee. The site is cha racte ri zed by 1 ow ~e 1 oci ties during high stage conditions. The creek bottom was covered with silt until late in the sampling season when the lowered discharges and increased velocities flushed the silt from the channel exposing a gravel substrate. The banks were perpendicular to the water surface and slightly undercut on the outside of the sharp bends. The creek, in the study site, can be characterized as relatively stable and meandering with ~hrubs on the banks providing cover . -39- - DRAFT ~lough -West Bank Three study sites were established in a complex slough system on the west bank of the Susitna River, and called Slough West Bank. The upper two study sites were dropped because preliminary investigation determined t hat the lower site would typify the habitat for this area. Lit t le change was observed in this site (Appendix A, Figure 17) until late sunmer/early fall when the lowered discharge of the mainstem permitted a slight backflow of the mainstem Susitna River water into the slough. A bloom of algae was observed at that t1me. Due to high turbidity, the substrate was not observable. Probing indicated the substrate to be primarily si 1t with some embedded gravel of undetermined size. During high discharges, overhanging riparian vegetation provided cover along of both banks. Sheep Creek Slough The study site (Appendix A, Figure 18 ) is located at the confluence of Sheep Creek Slough and the mainstem Susitna River. 1'1ainstem Susitna River water is permit~ed through the heaJ of this slough only under extremely high discharge conditions. Even under these conditions, the influence of mainstem water on the study site was minimal . Sheep Creek exerted the dominant water influence on this site for the entire sampling season . The channel bottom was s ilt laden throughout the entire sampling season. Overhanging riparian vegetation provided cov~r along most of the north bank but was less extensive on the southern bank. Concurrent with the low discharges at the end of the sampling season, a build up of sand was observed at the confluence of the mainstem Susitna River and the slough. -40- • • • DRAFT Goose Creek 1 On the east side of the Susitna River , approximately six miles upstream from the mouth of Sheep Creek Sloug h, a study site (Appendix A, Figure 19) was established at the mouth of Goose Creek. Approximately 1-2 miles upstream from the mouth of Goose Creek, a branch from Sheep Creek enters Goose Creek. Thi s results in the wa t er at the mouth of Goose Creek to be a mixture of the two water sources. Early in the sampling season a wedge of sand entered the top of the site. The sand progressed rapidly downstream to cover the creek bottom over the entire site. The lowered discharges and i ncreased velociti e s at the end of the season flushed the sand exoos i ng a grave 1 substrate. The mouth of the creek was stable in most respects . Goose Creek 2 A second study site (Appendix A, Figure 20) on Goose Creek is located approximately one mile north of the main mouth of Goose Creek. This site is located at the confluence of the mouth of a small braided channel off Goose Creek and a mainstem Susitna River slough. The creek substrate consists of sand, which was deposited by the stream at the head of a large deep pool in the slough. The stream water was slightly turbid f or most of the season and cleared at the end of the sampling season. The s l ough was t urbid throughout most of the sampling season. Once the mainstem Su ~itna River stage dropped at the head of the slough, a gravel bar at the her.d of the slough blocked the flow of mainstem Susitna River water entering the slough, allowing the slough -41- • • • DRAFT to clear. At the end of the sampling season, the mouth of the slough had a riffle zone passing less than six inches of water. Cover in the stream section is limited to riparian vegetation and a small amount of debris . Cover in the slough is limited to a debris jam at t he junction of the stream and the slough, a deep pool and a few boulders. No significant change in the structure of the site was noted throughout the sampling season. Mainstem -West Bank ~1ainstem -West Bank is located 1.5 miles north of Goose 2, on the west bank of the Susitna River. This study site {Ap pendix A, Figure 21) is located at the lower end of a complex slough system that is approximately two miles in length and 0.5 mile wide, including the islands and channels. The site was turbid unt i l it cleared toward the end of the sampling seaso:• when the dis- cha rge of the Susitna River dropped, dewatering the head of the slough. A gravel bar that divided the upper half of the site was submerged as the discharge increased. Thin ice and low discharges were observed at the end of the sampling season. Overhanging ripa rian vegetation was present along most of the banks during high discharges . As the discharges decrea!ed, the vegetation provided cover only along the deeper we st bank . At this time the bottom was 100% gravel over most of the site. Montana Creek T~1o and a half miles north of the Mainstem-West Bank site, on the east bank of the Sus itna River, a study site was established at the mouth of Montana Creek -42- - • DRAFT (Appendix A, Figure 22}. The channel shape and bedload at this site appeared to be the most dynamic of the sites in the Sunshine reach . The upp er three- fourths of the site was low in turbidity throughout the entire sampling season while the turbidity of the lower quarter was dependent on the influence of the Susitna River. The geomorphology of the upper half of the site varied mainly with the discharge of the creek, while in the lower half the channel and substrate shifted with the discharge of the Susitna River . Cove r types were diverse at this site, including overhanging riparian vegetation along both banks, sea ttered poo 1 s, debris and i so 1 a t ed undercut banks. The types of habitat available in the lower half of the site va ried with the level of the water. The substrate consisted mainly of gravel with some sand present. The sand was deposited in areas of low velocities and between the gravels of the bottom . iii. Talkeetna Reach (1} General description. The Ta 1 keetna reach {Figure 7) encompasses the area a 1 ong the Sus i tna River between the Parks Highway Br i dge (R.M.) 83.5) and Curry (R .M. 120.7}. There are 11 general habitat evaluation study sites located in the Talkeetna reach including: -43- • llRAFT Study Site River Mile Geographi: Code Mainstem 1 84.0 24N/05W/10/DCC Sunshine Creek 85.7 24N/05 W/1 4/ AAB Birch Creek Slough 88.4 2 SN/OSW/~:5/DCC Birch Creek 89.2 2SN/OSW/:!S/ ABO Cache Creek Slough 95 .5 26N/05W/J5/AOC Cache Creek 96.0 26N/05W/~6/DCB Whiskers Cr eek Slough 101.2 26N /OSW/'J3/AOB Whiskers Creek 101.

The confluence of the Sus i tna, Ta 1 keet 1a and ~ Chulitna Rivers separates the upper and l ower areas. The Susitna River in the • upper area is relatively straight to meandering with minimal brai di ng The approximate gradient of the upper area is 8 .0 ft./mile (correspon d i•'9 to a 175 foot drop in elevation over 22 miles). Typical substrate is gravel, I'Ubble and cobble with lesser quantities of sand, silt and boulders present. The lower Susitna River porti on, by comparison, is moderately braided. Silt is a major substrate type with gravel and rubble present. The approx imate grad ient over the lower area is 6.7 ft./mil es (corresponding to a 100 foot drop in ele- vation over 15 miles). The approx imate gradient of the entire re3ch i s 7.4 ft./mile. Vegetation over th~ entire reach is black spruce forest in :et·- spersed with muskeg bogs, mea1ows, and stands of cottonwood, birch and aspfn . -44- • DAAFT J\c .-ess along this reach is limited. In the low er area, pu blic access is provided by unimprove~ roads into Cache and Sunshine Creeks and boat landings ot the Parks Hig hwa y Btidge and Talkeetna. Above Talkeetna, access is limited to the rai 1 road and oth er remote transportation means. Year round an d seasonal home si tes are located along the entire reach with yea r round settle- ments at Tal Ke etna , Cache Creek (R.M. 96.0) and Chase. Recreati onal uses of the river alon g t his reac h include hunting, fishing, boating, hiking and campin g . Mainstem 1 (2) Description of gen er al habi t at study l:Jcations i n the Talkee tna Reach. Ma ins tem 1 (A ppe ndix A, Figure 23) is l oc ated at the con f l uence of Sunshine Slough with the mainstem Susitna Riv er. The mainstem Susitna River ha s a major influence on the overall chemi cal and physical nature of the site. The study site is a deep (15-25 feet) back eddy pool type habitat. Sampli ng gear placement. was both on the s teep east bank and an adjacent island. The substrate of the east bank is characterized by sand and silt interspersed with large boulders. Cover is provided along the steep bank by fallen and overhanging trees. The t sland is predominantly silt . Shrubs occur above the high water line and grasses provide cov er along the gentl y sloping banks. -45- ' DI<AFT Sunshine Creek The mouth of Sunsh ine Creek is located at two dist inc t sites depen d i ng on the st.:-~,. of Su nshi ne Slough (App endi x A, Figure 24). Since the mouth of the creek is the study site, two separate study at ·~as are located at this general habitat evaluation study s1te . Under high discharge cond itions, the mouth of Su nshine Creek is at an uppe r site. The upp er area is a creek /slough confluence system . The channe l is re lativel y unifonn in noss section containing gravel and rubble overlade n by 4-12 inches of silt and san d. Cover is provided along the sloping banks by overhanging trees and shn:bs with submerged veget c t ion present . A 11 samp 1 i ng gear p 1 a cement was a 1 ong the no r thw es t bank. Th e lowe r area is a slough/creek system that is predominately influenced by Su nshine Cr eek during l ow discharge conditions and becomes a branch of Sunshine Slough under high discharge condit ions. This area is sampled as the mouth of Sunshine Cre ek during periods of low di scharge . The stream at the lower area has a partially silted ch ann e l with gravel and rubble pre s ent. Cover is provided along steep banks by ov e rhanging ard fallen trees. The channel is partially obstructed by several log and debris jams. Birch Creek Slough The study site (Append ix A, F; gu re 25) is 1 oca ted at the confluence of Birch Cre ek Slough and the ma i nstem Susitna River. The primary influence on this slough at the mouth ultimately depends on the stage of the mains tern Susitna River at the head of Birch Creek Sl ough. During periods of low mainstem Susitna River discharge , little or no flow pa sses through the head of the slough, caus ing the primary influence of the slough at the mouth to be -46- DRAFT dependent on Birch Creek . Under these condit ions the water in the slough is clear. During pe riods of high mainstem Susitna River discharge, flow enters at the head of the slough. Under these conditions, the primary influence on the s 1 ough at the mouth is dependent on the rna i nstem Sus itna River . The slough in the study site has a relatively uniform channel containing gravel and rubble as substrate overladen by 6-12 inches of silt. Cover is provided along steep banks by overhanging and fa ,l en trees . Birch Creek The study site {Appendix A, Figure 26) is located at the confluence of Birch Creek and Birch Creek Slough. Under periods of high discharge, the site is a pool type habitat. Cover is provided along sloping banks by overhanging trees and shrubs and submerged vegetation. Under periods of low discharge, riffles form in addition to the pools . The typical substrate. in the study area is gravel and rubbl~ with sand and silt present. A seasonally used cabin is located at the mouth of the creek. Cache Creek Slough \ The study site {Appendix A, Figure 27) is located at the confluence of Cache Creek Slough and the mainstem Susitna River. Due to the proximity of the site to the confluence of the Chulitna and Susitna Rivers {so that complete mixing of the rivers has not yet occurred) and its west bank location, the site is heavily influenced by the Chulitna River . The slough in the study site is braided with sand and silt bars present. Sand and silt are the major substrate types. Except during periods of very low discharge, at -47- - DRAF I which times the sl ough runs clear, the study area i s pr i mar ily i nfl uenced by slough water. Cover is provided along sl oping banks oy fallen and overhanging trees and areas of submerged vegetation. Cache Creek The study site i s (Appendix A, Figure 28 ) located at the con fl uence of Cache Creek and Cache Creek Sl ough. The porti on of the creek i n the study site has l ow flows. As a result, the dissol ved oxygen l evels fall below saturation during the latter part of the salmon spawning runs. ln addition, specific conductances sharply rose during the spawning period . Cover is provided by a broken beaver dam and fallen and overhanging trees along sloping banks. Typical substrate is gravel and rubble overladen, i n most areas, by 6-12 i nches of sand and silt. Whiskers Creek Slough The study site (Appendix A, Figure 29) is located at the confluence of Whisker s Creek Slough and the mainstem Susitna River. The primary influence on thi s slough depends on the stage of the mainstem Susitna River at the head of Whiskers Creek Slough. During periods of low mainstem Susitna River discharge, little to no flow enters the slough, causing the primary influence of the s Iough at the mout h to be oependent on Whi sk ers Creek. Under these conditions the slough runs clear. During periods J f high mainste.m Susitna Riv~,. discharge, flow is permitted through the slough. Under these conditions the primary influence on the slough is dependent on the mainstem Susitna River. The slough in the study site is wide and s hallow with a relatively -48- • DRAFT unifonn cross section. Substrate i s gravel, !"'u bb le and cobble with boulders present. Extensive areas of the bed are covered with silt. Cover along the sloping banks is li mited, except for isolated areas of submerged vegetation. Whiskers Creek The study site (Appendix A, Figure 30) is located at the confluence of Whiskers Creek and Whiskers Creek Slough. Whiskers Creek in the study area i s a relatively narrow, meandering stream containing many riffles and pool s . Cover is provided along slqing banks by overhanging and fallen trees and shrubs and areas of submerged vegetation. Typical substrate in the bed is gravel and rubbl e partially silted over i n areas. Aquat1c vegetation is present in the channel. Slough 6A The study site (Appendix A, Fi gure 31 ) is locatea at the confluence of Slough 6A and the mainstem Susitna River . The slough receives very 1 ittle mainstem Sus i tna River influence due to a se ries of beaver dams crisscrossing the slough between its head and mouth. The slo'.l gh in the study area is a relatively quiescent, muskeg influenced system having a relatively deep unifonnly shaped channel. Typical bed substrate is silt interspersed with boulders, organic debris and aquatic vegetation. Cover is provided along s l oping banks by overhanging trees and shrubs and submerged vegetation, boulders and debris. -49- I Lane Creek The study site (Appendix A, Figu re 32) is located at the confluence of Lane Creek and the mainstem Susitna River. The creek in the study site is dynamic, constantly undergoing change in bed structure and geomorpho logy. The creek is a relatively narrow, shallow, fast running, clearwater stream containing many pools and riffles. Typical substrate in the creek bed is gravel, rubble and cobble with sand, silt and boulders present in areas. Aquatic vegetation is present in the channel. Cov er is prov i ded by overhanginq shrubs and trees, submerged vegetation and isolated boulders. Hainstem 2 The study site (Appendix A, Figure 33) is located on the east bank of the mainstem Susitna ~iver, at the mouth of a side ch annel . During periods cf low mainstem Susitna River discharge , the head of the side channel dewaters causing a large backeddy to fo~· in the upper segment of the study area. The study area ha~ several sand/silt and gravel, rubble and cobble bars. Under high discharge conditions, cover is provided by ov e rhanging and fallen trees along a cutbank. Under low discharge cond i tions, the entire area contains gravel, rubble and cobb ~e substrate, with r iffle zones present. -50- • • • DRAFT iv. Gold Creek Reach (1 ) General description. The Gold Creek reach (Figure 8) of the Susitna River extends from Curry (R.M. 120.7 -elevation 507.6 feet above MSL) to Portage Creek (R .M. 148.8 - elevation 820.9 feet above MSL ) and encompasses 28.2 river miles. The river forms a single main channel although several small islands and gravel bars divide the river in areas. Depending on the river stage, 2-3 feet standing waves are present i n sev eral places. Substrate varies from silt to bedrock with tne majority of mai nstem shoreline substrate being rubble and cobble. The major substrate of sloughs and slow water areas is silt . River elevation drops 313.4 feet in 28.2 river miles corresponding to an approximate gradient of 11.1 ft./mile . In the upper portion of this reach the river flows west. The banks are steep thus having good drainage and support a dense spruce hardwood forest. Below Gold Creek (R.M. 136.7) the river bends to flow south. Vegeta~ion and banks remain similar. Four principal tributaries empty into the Susitna River within this reach; Fourth of July Creek, Gold Creek, Indian River and Portage Creek. They are generally turbulent and t he ir channels at the Susitna River confluence exhibit noticeable changes in physical character as discharges vary. Access to this area is limited. The Alaska Railroad follows the river closely from Curry to Indian River. The stretch of the Susitna River above Indian -51- - DRAFT River is accessible only by hel i copter or boat. There is an unpaved runway for landing fixed wing aircraft near the Go l d Creek Br i dge. A gold dredge is operated on Go l d Cree k not far abo ve the confluen ce wi th the Sus i tna River .

Due to a bend in the river above the sample site eddies are constantly forming. Substrate at the upper portion of the study site is mainly sand and silt. Build up and shifting of sand and silt occurred. Ground water percolated up from the bed in several of these s.andy areas. ·water clarity was influenced by the Susitna River. Under low discharge conditions, when the Susitna River no longer entered the study area from above, the sample site was reduced to a narrow inlet. Under these con- ditions, the direction of flow reversed 180°. Susitna Side Channel (Su-Side Channel} The study site (Appendix A, Figure 35) in this mainstem Susitna River side channe l /cut bank is located one mile above Curry on the east bank at the Susitna River. The railroad closely parallels the bank at the lower end of this site. As floods began eroding the bank (Jul y, 1981), large boulders were moved in by railroad personnel to stabilize the area . This altered the bank -53- • URAFT and substrate of the lower 75 feet of the site. Depending on di scharge, the soil cut bank varied from 1-4 feet high and was undercut in sever ,l places. The ban k s upported a dense growth of overhanging ferns, hemlock, a 1 der and willow. Subs t rate var i ed from soi I and sil t to grave l and rubb l e. Many debris piles and fallen trees occurred al ong the sh ore li ne and caused numerous small eddies and slack water areas . A clear nart'ow sl otJgh empt i es intc the mainstem from the east bank several yards above the site. Specific conduc- tance measurements were rarely stable because the clear and turbid waters had not yet mixed. Ma 1nstem Susitna -Grave l Bar (Su-Gravel Bar ) This study s1te {Appendix A, Figure 36), which is located one mile below Slough SA, is a l~rge, exposed gravel bar at the lower tip of an i sland that separates the Susitna River ma in channel from a side channel. Substrate wi t hin the sample area consists of sand, gravel or combinations thereof. Samp 1 i ng occurred on the west side of the grave 1 bar. The ma i nstem Sus i tna River water is fast flowing with several small eddies along the shore. As discharge increased, the gravel bar became submerged . During these periods, sampling occurred at the IO\oler tip of the aforementioned island. Sampling gear was placed along a 3-4 foot h:gh cut sand bank that supported overhanging alders . Water at this location was shallow and slow moving . Substrate was lOOS sand and sh i fted radically in high water. At the upper (east) end of the bank, ground water percolated up and, when the channel to this site was cut off by shifting sands, spri ng s were visible. The trapped water was clear exhibiting relatively high specific conductances and dissolved oxyge n lev~ls below saturation . -54- DI<AFT Slough SA Slough SA (Appendix A, Figure 37) is a calm relatively shallow, murky slough. The substrate is mostly s and exc ept at the upper end of the sample area where two branch es of clear water flow over gravel, rubble and cobble. A thin s i1 t 1 ayer covered the rocks in 1 ow to med i urn water 1 eve 1 s. The 1 ower mud banks of the slough are covered with grass and equisetum; further from the water the banks are covered with dense willows, alders and cottonwood s . The turbidity of the slough varied with precipitation and the flux of mainstem Susitna River water entering at the head of the slough. 4th of July Creek At 4th of July Creek (Appendix A, Figure 3S} sampl i ng was conducted both in the creek and i n the mainstem Susitna River to a po i nt 500 feet below the mouth. The geomorphology of the creek from the mouth to a point 200 feet upstream changed radically throughout the sampling season. Deposits of shifting gravel and rubble in and above the mouth caused drastic rerouting of creek channels. A large log jam occurred 100 feet above the mouth after the first heavy ra i nstorm of the summer. Several deep holes existed in the creek at the beginning of the sumner. After the di scharge dropped, the deep holes were filled by r,ravel, leveling the bed. The substrate of the mainstem Susitna River area sampled is mostly gravel and rubble . The banks are fairly flat and support dense growths of willows, alders, and cottonwoods. Several -55- • • DRAFT m~nor creek channels empty in t o the mainstem throughout the study area . The mainstem wa te r is turbid, but along the s hore , water flows clearer due to the creek's influence i mmed iately up stream. Slo ugh 10 Slo ugh 10 (A,!)endix A, Figure 39') is a deep slow water slough with two water sources: a clear tributary from the nor th and a narrow Susitna Riv er side c hanne l f r om the northeast. At l ow wa~er discharges, the Susitna Riv er s1de channe l exhib i ts greatly reduced inflow. The sampl e area became l ess turbid under these conditions . The wes t bank i s stee p w~th bedrock outcrops. The east bank is a large sand and gravel bar that supports a s parse growth of yo ung willows and alders. The east bank of the clearwate r tri buta ry is f l at with dense brush . Sub strate varies from sa nd to silt. When wate r leve ls were in a state of flux, the sand and silt shifted radically within the site and became like qui ck sand . When the discharge dropped, a sand bar {7 0 x 150 feet ) formed at the confluence of the clearwater and silty slough water. From the sand bar to the upper sample site boundary , specif ic conductancr! measurements were unstable. Slough 11 Slough 11 (Append ix A, Figures 40 ) is relat i vely stable. The west ba'lk, 4 -8 feet high, is flat and supports a dense growth of a l ders. The east bank is 30 feet steep with bi rch and s pruce trees. The lower s ection of Slough 11 is relat ~vely wide, with slow moving water . Substrate is silt.· The upper -56- • • DRAFT area is narrow and riffled in places. rubble to boulders (10 -13 inches ). Substrate varies f rom sand, gravel and As discharge s dropped toward the end of this samp li ng season a large mud bar fo rmed across the mouth of t he slough and Susitna River confluence. Mainstem Susitna -Inside Bend (S u-Go ld) The insi de bend study site (Appendix A, Fig ure 41 ) located 0 .5 mile ab ove t he Gold Cree k Bridge is on a ma instem Sus itna island. Sampl ing occurred on the lower west side of the island. ihe mainstem Susitna Rive r flowed fast, deep, and turbid near this site. The shore of the study area i s a raised sand, gravel, rubble and co bb le bank. Under high discharge co rditions the ban k was flooded cau sing s hifting of the bank substrate. Under e>tremely low discharges, a grav e l bar su rfaced extend i ng across the east charnel of the Sus itna River al mos t to the east bank . I ndian River Sampling at Indian Ri ver was conduc t ·. ~om the mouth t o a point approximately 500 feet upstream and along the mainst r~l t na River 200 feet down ~i ver from the mouth (Appendix A, Figure 42}. Tt·• "' of In dian River was dynamic, constantly undergoing ch ange in bed stru, .. geomorphology. Deadfall and debris was deposited on gr ave l bars throug h~~ the area of the mouth depending on channe l routing . Water f l owed both deep and fast, and shal l ow i1nd slow. Substrate varied from sand to gravel and rubble. Susitna River water below the Indian River mouth varied in turbidity as the two bodies of water had not mixed completely. -57- • • DRAFT Slough 20 Slough 20 (Appendix A, Figure 43) contains diverse habitat. During medium to high Susitna River discharges, the mainstem Susitna River feeds the head of the slough at the upper end of the study site. A smal l clearwater tributary empties into the slough 250 feet from the head of the slough. Also, several nearby springs feed into the slough . Midway along the slough, Waterfall Creek empties into it on the southeast bank. The study area contains deep pools, deep s low moving water, shallow riffles, and water trickling through gravel, rubble and cobble substrate. Substrates consists of sand, gravel, rubble, cobble and combinations thereof. Under clearwater conditions, a thin layer of glacial flour film was visible over the rubble and cobble areas . Both banks are vegetated by dense willows and alders or dense cottonwoods and alders . Bank heights vary from 0-4 feet. "At the slough mouth, banks consist of sand gravel and rubble. Mainstem Susitna -Island (Su-lsland) The mainstem Susitna River island study'·site (Appendix A, Figure 44) located two miles below Portage Creek is relatively stable. Both sides of the western tip of the i sland were sampled. The island is approximately 400 feet in width at the widest point of the study area. During low discharges, the western tip of the isl and is a large sand bar . Both north and south banks contain rubble and cobble. Vegetation on the i sland consists of dense stands -58- • • DRAFT of alders . Although both mainstem Susitna River channels flow relatively fast, deep, wide and turbid, during low discha~es t he south channe l appeared to be the main channel. Portage Creek Portage Creek (Appendix A, Figure 45) is the uppermost gener~l habitat evaluation study site sampled within thi~ reach. Study area extends 475 feet upstream fro.1 the creek mouth , 380 feet down the Susi tna from the creek mouth, and 100 feet up the Susitna from the creek mouth. The creek width at the mouth is approximately 250 feet in medi um to high d ischarges . The rel ati vely high steep banks are densely vegetated with birch and alder. The creek occupies one channe l until it r eaches two main bars that are present at the mouth . Depending on the discharge of t he cree k , the two bars spl ft into s evera l sma ll er bars c ausing a delta t c form . Substrate shifted as the geomorphology of the mouth changed. The substrate is composed of gravel in the mainstem and near the mouth, and ru bble and cobble in the creek and on the highest part of the bars. The c reek in the study area is rapid, clear, and relatively deep {3 - 5 feet). Mainstem Susitna River water flow above the creek forms a turbid eddy. Mainstem Susitna River water below the mouth does not yet mix with the creek water, causing va riable turbidities. (3) Special studies -he licopter surveys of Ind i an Ri-ter a nd Portage Creek. Three sites eac h along the upper Ind ian River and upper Portage Creek were sampled for general habitat evaluation studies. Sampl ing wa s conducted v i a -59- • • DRAFT helicopter in early June, late August, and early October 1981. Sampling was not conducted in July and August due to bad weath.~r conditions. Sites I and II (the lower of the III sites) of both tributaries remained at the same locations during each sample period. Sites III on both Indian River and Portage Creek were relocated after the initial sampling period. Tributary miles and geographical codes of sampling locations are shown in Table 4. Table 4.

The river in the lower 400 feet of this site forms a single channel. Th~ river in the upper 400 feet contains two small gravel bars that become bank extensions under low discharge conditions. This shallow clearwater river flows fast over a gravel, rubble and cobble substrate. The east bank is steep and densely vegetated with spruce, birch, and cottonwood. The west bank is flat with similar vegetation. A small side channel (approximately 12 feet i n width) rejoins the ma i n channel at the lower site boundary . This channel was dry when the s i te was vi s i ted i n October . indian II Indian River at site II forms a single, shallow channel with fast flowing clearwater over a rubble and cobble substrate. A bar (approximately 100 feet in length) divides the channel midway up the site. A small creek empties into the river at the east bank above the bar. Both river banks are densely populated with overhanging willows and alders. During low discharges, riffles appeared along this stretch of the river. Indian III The J une location of site III differed from the August and October l ocation. When sampling in August and October, the June study site could not be located. -61- OI<AFT Thus a new representative s;te wc>c; establhhed nearby. At the latter site, the channel is braided and meandering. Both banks are low and vegetated. Mid-channel bars lack vegetation, but have debris pile ups. Substrate is gravel and rubble . At the upper end of the site, slow water from an upstream beaver dam empties into the river. This water source is clear with a red -brown tint . Substrate in this area is silt of a non-glacial origin. Fa l len trees and brush _pil es are scattered along t he mud banks of the slow water area. Portage Creek The lowest site ll) on Portage Creek has two side channels to the east of the main channel . In the main channel and nearest side channel, water is fast flowing. The substrate consists of rubble and cobble. The farthest of the -channels has slow moving water with several clear pools . This channel appe4red to have been dammed below the study site by beaver. Banks are low in relief with dense brush. Portage Creek II Portage~ Creek at site II has a fairly straight, main channel with two side channels present . Flows are fast and uniform over a rubble and cobble substrate . Low discharges in October dewatered the middle channel. The depths of the east channel varied from three feet to less than a foot. Banks are steep with bedrock outcrops. -62 - • • • DRAFT Portage Creek III Site III on Portage Creek was the uppennost site sampled on this tributary. Because of a waterfall below the original site III, the site was relocated from the east fork to the north fork of Portage Creek. The latter site III includes two small side channels; one on either side of the main channel . Substrate is predominantly gravel, rubble and cobble. Small pools in the west channel contain some sand substrate. Willow and alder provide bank cover . v. Impoundment Reach (1) General description . The upper Susitna River from Devil Canyon to the Oshetna River is a remote wilderness area of high aestheti c and recreational value. Mountainous terrain dom inates the area with elevations rang ing from 1000 feet near the basin floor of Devil Canyon to over 6000 feet on various mountain peaks in the area. The landscape varies from treeless alpine tundra at higher elevations to low lying areas dominated by black spruce interspersed with muskeg bogs. Occasional stands of cottonwood, birch and aspen are often found throughout the area, especially at lower elevations. Access to the area is limited mostly to aircraft. However, portions are also access i ble by boat on the Susitna River launched at the Denali Highway Bridge. Kayakers have been known to f i oat this enti r e reach through Devil Canyon. The water3hed of the Susitna River above Devil Canyon includes several major tributaries of glacial origin. These streams carry a heavy load of glacial -63- • • DRAFT flour during ice-free months. There are also many smaller tributaries which normally run clear year round. The Susitna River from Devil Canyon to the Oshetna River can be divided into two distinct geomorphological regions: Portage Creek to Fog Creek and Fog Creek to Oshetna River. The river between Portage Creek and Fog Creek fonns one channel which 1 ies in a deep valley along most of this route. The average gradient is a~proximately 20 ft./mile. From Fog Creek to the Oshetna River the channel is wider and often splits into two or more channels with an average gradient of approximately 12 ft./mile. According to a 1977 report by the Alaska District of the Army Corps of Engin~s updated by Terre~trial Environmental Services (Schmidt 1981) the two proposed impoundments in this a rea wou 1 d inundate approximate 1 y 80 mi 1 es of the main river with a total surface area of about 50,500 acres. This would include that portion of the Susitna River from the proposed Devil Canyon dam site (R.M. 152.0) to a point approximately four mi1es upstream from the Oshetna River (R.M. 231.0). The proposed Devn Canyon dam would create an impoundment 28 miles long with a maximum surface elevation of 1455 feet MSL and a surface area of 7,550 acres. The proposed Watana Dam (R.M. 182.0) would create an impoundment that would extend for 54 miles and cover 43,000 acres. It will have a maximum surface elevation of 2215 feet MSL. Due to the inaccessibility of the Devil Canyon area, and the lack of suitable fisheries habitat, the study area was limited to that section of the Susitna River from Fog Creek to the Oshetna River. Eight habitat locations were chosen within this area for general habitat evaluation studies. ihese sites were located on the eight major tributaries in the proposed impoundment area . -64- DRAFT The selection of these sites was based on preliminary studies done in 1977 by the Alaska Department of Fish and Game for the U.S. Fish and Wildlife Service (ADF&G, 1977). These general habitat evaluation study sites, along with their respective river mile and geographic code are presented in Table 5. All study sites within the impoundment reach are 500 feet in length with alternating 500 foot non-study areas i n be':ween (Figure 10). The initial site at a general habitat evaluation location is always located at the mouth of a particular tributary and successive sites are numbered upstream to a point not exceeding 4500 feet. This procedure essentially covers the lower mile of each tributary. In most cases there are a maximum of five study sites within each general habitat evaluation location. However, in some areas it was not possible or necessary to have the maxilllJm nuni>er of sites. In these cases fewer sites were utilized. Study sites were sampled on a monthly basis. However, various logistical problems and adverse weather sometimes interfered with this schedule. In addition to the regular sites 1 is ted in Table 5, Sally Lake was sampled for basic water quality data one time over the course of this season . Th i s data is presented in Appendi x B. Access to all general habitat evaluation locations required initial helicopter support . Where possible. rafts were used to gain access between areas. Individ~al study sites were reached by hiking upstream from the mouth of each tributary. Remote areas in the upper sections of selected streams also required helicopter support. -65- Table 5.

Fog Creek is 1 oca ted at river mile 173.9 on the south side of the Sus i tna River and is approximately 23 miles upstream from the proposed Devil l:anyon Dam. The stream would be inundated to a point approximately 0. 7 miles up- stream by the proposed impoundment. Three study sites (Appendix A, Figures 46-48) were established in the lower 2500 feet of the stream. This clearwater stream is relatively narrow and shallow with widths ranging from 50-75 feet and average depths of 1-2 feet. The stream habitat is predominant i y riffle with few pools and little cover present. Substrate consists mostly of rubble and cobble. Most of the study area consists of one stable channel except for the lower 500 feet where it becomes braided. During periods of high discharge, many backwater areas were present. The stream channel at the mouth was dynamic during the season due to the fluctuating discharges of both the Susitna River and Fog Creek. Tsusena Creek Tsusena Creek i s located at river mile 178 .9 on the north side of the Susitna River and lies approximately 28 miles upstream from the proposed Devil Canyon Dam. Only the mouth of this stream will be affected by the proposed impound- -68- DRAFT ment since it lies nea r the projected Devils Canyon impound ment elevation of 1455 feet . Therefore, on ly one study site (A ppend ix A, Figure 49) was established at this location. The study site co nsi sts of a split chan nel with two distinct habitat types. The eas t channel is a wide fast f l owing secti on approxi mat~ly 100 feet wide with average depths of 2-4 feet. This section is characterized by riffles and whitewater areas with no prominent pools or cover available. Substrate consisted of co bble and large boulde rs. The west channel was between 25-50 feet wide ~ith average depth of 1-2 feet. This channel consisted of alter- nating pool /riffle areas with some cover availabl e along the bank. Substrates consisted of grave 1 and rubb 1 e. Both stream channe 1 s \lere stab 1 e and the water remained extremely cl ear desp ite heavy rains dur ing the su11111e r. The s plit channel resulted in the formation of two mouth s with a large gravel bar separating them. Th is area was dynamic throug hout the season and was often i nundated by the high water of the Susitna . Deadman Creek Deadman Creek i s located at river mile 183 .4 on the nor t h side of the Susitna River and lies approximately 1.0 mile upstream from the proposed Watana Dam. Approximately 2.3 stream miles would be inundated by the proposed i mpoundmen t . Becau se of a deep canyon and large waterfall past the first half mile, acces s to this area was limited and orly two study sites (A ppendi x A. Fi gures 50-51) were established in the firs~ 1500 feet of stream . -69- DRAFT The study area of Deadman Creek is an extremely fast and turbulent whitewater area with a relatively steep gradient resulting in few pools and little cover. A large waterfall, which is presently a barrier to fish migration, is locot ed approximately 1.0 mile upstream from the mouth. The stream c~annel below the falls is stable and is situated in a deep canyon for most of this length . Channel widths are between 75-100 feet and average depths are 3-5 feet. Substrates consist mostly of cobble and boulder. Above the falls stream gradient is not as steep and many pools are present. The proposed impoundment would inundate the waterfall a nd allow fish migration between Deadman Lake, approximately 10 miles upstream, and the Susitna River . Watana Creek Watana Creek is located at river mile 190.4 on the north side of the Susitna River and is approximately 8 miles upstream from the proposed Watana Dam. About 9.0 stream miles would be inundated by the proposed impoundment . Five study sites (Appendix A, figures 52-56) were established in the lower 4!>00 feet of stream. Due to high water and steep terrain study sites 4 and 5 were inaccessible after t he month of June . Watana Creek is a shallow meandering stream approximately 40-60 feet wide with depths averaging 2-3 feet. It has a shallow gradient resulting in a moderate flow with few pools interspersed between the predominent riffl e areas. The substrate consists mostly of gravel and ru ~ble. The water was often turbid during the summer because of heavy rains and unstable soils present upstream. The stream channel itself was stable and did not appear to shift except at the -70- -------------------------- DRAFT mouth where a dynamic multi-channel system was present during periods of high flow. During low discharge periods only one main channel was present at the mouth. Kosi na Creek Kosina Creek is located at river mile 202.4 on the south side of the Susitna River and lies approximately 20.0 miles upstream from the proposed Watana Dam. About 4.0 stream miles would be i nundated by the proposed impoundment. Fiva study sites {App endix A, Figures 57-61) were established in the lower 4500 feet of stream. Kosina Creek is a deep ar.d turbulent stream which is predominantly whitewater interspersed with deep pools and shallower riffle areas which provide excel- lent fish habitat. Average depths are 3-4 f 'et but there are several pools which exceed 6-8 feet in depth. Substrates consist mostly of sand, large cobble and boulders. The stream channel is stable and is situated in a narrow valley with a moderate gradient. It is often braided with total widths frequently over 200 feet. A split channel resulted in the fonnation of two mouths approximately 150 feet apart with a large tree cove red island separ-. ating them. The west channel, which is the larger of the two, is predomi - nantly whitewater and is about 125 feet wide. The east channel is slow f lowing and shallow with alternating pool/riffle areas. -71- DRAFT · Jay Creek Jay Creek is located at river mile 203.9 on the north side of the Susitna River and lies approximately 22 miles upstream of the proposed Watana Dam. About 3.0 stream miles would be inundated by the proposed impoundment. Fi•1 e study sites (Appendix A, Figures 62-66} were established in the lOOAe 4500 feet of stream. Jay Creek is a relatively narrow, snallow stream predominantly riffle with a moderate flow. It is between 40-60 feet wide wi t h depths averaging 1-3 feet . Substrate consists of gravel, cobble and rubble often embedded in sand . Although the water is generally clear, unstable soi ls 1n upstream areas often result in landslides which can ch ange the wat~r to a turbid condition wi thin minutes. The stream channel itself is stable. The channel splits about 100 feet from the Susitna resulting in two distinct mouths. These mouths are influenced by the changing water level of the Susitna but the effects are minimal. Goose Creek Goose Creek is located at river mile 224.9 on the south side of the Susitna River and 1 ies approximately 43 miles upstream from the proposed Watana Dam. About 1.5 stream miles would be inundated by the proposed impoundment. Five study s ites (Appendix A, Fi gures 67-71} were established in the lower 4500 feet of stream. -72- DRAFT Goose Creek is a narrow, shallow stream approximately 40-60 feet wide with average depths of 2-3 feet. The habitat is predominantly riffle with a moderate flow and few pools. Substrate consists of rubble, cobble and boulders often embedded in sand. The stream channel and banks are stable and the water usually remains clear even during periods of moderate rains. The discharge of Goose Creek would fluctuate considerably with a significant amount of rainfall and this would often result in a braided channel at the mouth. The mouth was also influenced significantly by the water level of the Susitna River. Durin~ periods of high discharge, large amounts of silt and sand were deposited at the mouth only to be washed away by the waters of Goose Creek after the water level of the Susitna had receded. Oshetna River The Oshetna Ri ver f s 1 ocated at river mile 226.9 on the south side of the Susitna River and lies approximately 45 miles upstream from the proposed Watana Dam. About 2.0 stream miles wo ul d be inundated by the proposed impoundment . Five study sites (Appendix A, Figures 72-76) we r e established in the lower 4500 feet of stream. The Ushetna River is a large, meande ring stream approximately 100-125 feet wide with average depths of 3-5 feet . StrP.amfl ow is s 1 ow to moderate with alternating pool/riffle areas which provide excellent fish habitat. Substrate consists mostly of rubble and cobble with some large boulders. The stream channe 1 is stab 1 e throughout the study a rea and contains many 1a rge grave 1 bars. This stream is partially under glaci al i nfluence and the water was often turbid even during periods of dry weather. -73- DRAFT b. General Habitat Evaluation Study Site Physiochemical Data Dissolved oxygen, pH, water and air temperatures, turbidity and specific conductance were measured twice monthly at each general habitat evaluation study site, except in the Impoundment reach, whe r e these parameters were measured monthly. The data are presented for each site in a graphical format versus specific points in time (Figures 11-93). The data are also presented in tabular form in Appendix B. c. Thermograph Data Water temperature data were continua'ly recorded at 29 sites in the study area (Figure 94, Table 6) using Ryan Model J 90 day thermographs. The data were converted into daily means, calculated as the mean of twelve, two hour point temperatures. The temperature data for each thermograph site are presented as a function of time (Figures 95-117; Appendix C, Tables 1-23). d. S~age Data Stage data were collected at three AA f ishwheel sites and each lower river general habitat evaluation study site (Figure 94, Table 7).

B. SELECTED HABITAT EVALUATION 1. Methods a. Physi·ochem1 c~ 1* Water quality and discharge data were collected on a cooperative basis with the USGS at five selected habitat evaluJtion ~tudy sites. Sampling was timed to coincide with other USGS sampling of the mainstem Susitna River at the Gold *Specific methods are presented in Appendix G. -192- l • • ' DRAFT Creek bridge. A sampling site within each selected habitat evaluation study site was chosen to ensure that a representative sample would be obtained and in an area where the sampling apparatus would operate most efficiently. All sampling was done accordingly to USGS standard operating procedures. The following is a brief outline of the sample procedures used. Discharge was measured using a Price AA or a pygmy flow meter. Five points along the transect were deterined which divide the discharge into 20~ increments. At each of these points a depth integrated sample was taken using a DH-75 sa~ler. These five samples were then composited using a "churn splitter11 , a device that thoroughly mixes the samples. Portions were withdrawn and treated appropriately for shipment to the USGS laboratory in Colorado for analysis of nutrients, sediments, cations and trace metals listed in Table 2. Field parameters (dissolved oxygen. specific conductance, pH, and temperature} were measured using a Hydrolab Model 4041 at each of the five sampling points on the transect. Substrate was categorized as shown in Table 3 . Thennographs were placed in two sloughs {19 and 21} to measure surface and intragravel water temperatures. The intragravel thennographs were placed in weighted fry traps and buried approximately one foot into the substrate. The thennographs measuring surface water temperature were also placed within weighted fry traps and placed upon the substrate. Each were secured to the shore using 1/4 inch wire cable. b. Surveying Methods The survey-hydraulic portion of the study consisted primarily of the selection and surveying of transects within each selected habitat evaluation site. -193- DRAFT Transects in the slough were selected to characterize the variety of hydraulic and instream habitat availab le. Transects were located at the head (upstream confluence with the mainstem) and at the mouth (downstream confluence) of each slough to relate mainstem water surface elevation to the sloughs. Transects were also placed to characterize major control points, pools and riffles. Transects were marked on each bank with four foot sections of 1/2 inch rebar as head pins. These were driven into the ground leaving approximately 3 inches above the surface in areas on the bank that were, where possible, above the high water mark. Standard surveying techniques using a Lietz A-1 level, rod, and fiberglass tape, were employed to determine the cross sections, diagonal and longitudinal distances between each head pin and head p i n e l e- vations. The elevations were determined in relatit'n to an AOF&G bench mark which in turn was tied into an elevation datum previously established by an R & M Consultants transect bench mark for true elevation s. Cross sectional profiles were plotted for each transect to illustrate the morphology of the channel". A Topcon OMS1 Electronic Distance Measuring system and Raytheon DE-719-B depth sounder were modified for use with a boat boom suspension system for surveying deep water and wide river stretches. Photographs of the substrate were taken a 1 ong the cross secti ona 1 transect using a grid to identify substrate and its locations in relation to the left bank head pin. Photographs were 1 abe 1 ed and fi 1 ed for referenc·~. One staff gage was placed in each slough on a transect which exhibited channel characteristics suitable for accurate discharge measurements. Discharge and stage were determined in order to begin a period of record from which to -194- ·• DRAFT de'l~lop stage discharge relationships with subsequent measurements. Staff gages were also installed in the rr.ainstem at most study slough locations to characterize whether slough flow regimes are related to those of the mainstem. c. Si te Selection The fi'le selected habitat evaluation sites studied are sloughs located along the Sus1tna River from approximately five miles downstream of Sherman (R.M. 131 ) to approximately four miles upstream of Indian River (R .M. 138.5). These sites with their respective river miles and geographic codes are presented below: Site River Mile Geographic Code Slough 8A 125.5 30N 03W 30 BCD Slough 9 129.0 30N 03W 16 ABC Slough 16B 138.0 31N llW 17 ABO USGS Mainstem Site @ Gold Creek Bridge 136.7 31N UW 20 BAC Slough 19 140.0 31N llW 10 OBB Slough 21 142.0 31N llW 02 AAA The sites were selected to represent varied types of habitat, water quality and fishery activities {spawning and rearing), as determined from data collected by ADF&G (ADF&G, 1974, 1978, 1979), discussions with Acres American and R & M Consultants personnel, and by a reconnaissance trip in June of 1981 by AOF&G Su-Hydro and uSGS personnel. An add i tional objective was to select sites which would cnaracterize the general hydraulie conditions of sloughs in -195- DRAFT the river above the confluence of the Talkeetna River and below Devil ~nyon. Table 8 illustrates the parameters chosen in selecting the sites and how each slough compared. A comparative analysi s of the parameters presented in Table 8 indicates that each slough is relatively unique. An overview of the sites illustrates how slough SA with a pH range of 7 .D-7 .5 and a specific conductance of 88-98 contrasted with slough 168 which had a pH range of 6.2-7.2 and a conductivity of 85 while both were sites of coho and chinook rearing. Slough 19 was selected due to its relatively high range of specific conductance (140-150 }, and its popu lation of sockeye spawners and coho rearing fish. Additional chinook fry have not been observed in this slough whereas slough 21 (upstream } and slough 168 (downstream} each supported chinook fry. Slough 9 was selected because it supported high numbers of coho spawners a,;d numbers of sockeye (spawners } and few salmonid fry . Slough 21 was chosen being a site of high numbers of chum spawners with both chinook and coho fry. 2. Findings a. Site Descriptions . Slough 21 (Appendix A, Figure 77) is a forked, open channel stream approxi- mately 0 .5 miles in length with sloping 5 foot cutbanks. The main source of water i s generated from the mainstem Susitna River except during periods of low discharge. At low discharge of the mainstem, the slough is fed by a small, clearwater tributary entering the northeast ct.lnnel of t he slough . -196- • • • Table 8.

The substrate, from the mouth upstream approximately 750 feet, is composed primarily of silt sparsely interspersed with grave1 and cobble . Above this portion in the main channel and northeast channel the substrate is composed of silt, gravel and rubble. It was in these channels that all spawning activity was observed. The northeast channel substrate consisted primarily of rubble and cobble interspersed with gravel. No fish were observed spawning in this site here during the sampling period. The channel was also the first to dewater. The northeast channel due to the contribution of a small tributary was never found dewatered nor was the main channel of the slough. Slough 19 {Appendix A, Figure 78) is a spring fed stream backed up at its mouth by the Susitna River which fonns a pool for approximately half the sloughs length. The slough is aporoximately 0.2 miles long and has the unique feature of being completely spring fed •• The banks are sloping five foot cutbanks in the upper portion and generally sloping throughout the lower portion. The substrate is composed of 100% silt with scant aquatic vegetation from the m~Jth upstream approximately 200-300 feet. Abo \e this the substrate is primarily grwel with a layer of silt ending with cotble and rubble near the head of the slough. Sockeye were observed spawning in the slough. Redds were loc~ted by noting areas where the f i sh had fanned the silt to access the underlyin~ gravel. Slough 168 (Appendix A, Figure 79) is a free flowing channel approximately 0.4 mile in length consist~ng of steep, cutbanks along the entire length on both sides which range from 1-5 feet i n height. The substrate is fairly homo- -198- ' ' DRAF I geneous throughout, consisting primarily of gravel and rubble. The main sources of flow is from the ma1nstem Susana Ri ver which enters the head of the slough. During periods of low mainstem discharge, groundwater percolation contributes most of the water as the head of the slough is dewatered, isolating the slough from the mainstem i nfluence. Although s pawning was not observed during our surveys, a few chum salmon carcasses were found in de- waterd areas within the slough. Slough 9 (Appendix A, Figure SO) is an open water channel approximately 1.2 miles long having slopi ng six-foot cutbanks and substrate composed of gravel. rubble and cobble. The main source of water for the slough consists of flow from the mainstem Susitna River except during periods of low discharge. Two small tributaries which are located on the northeast and southeast banks maintain flow in the slough during low discharge periods . They provide the entire low flow discharge. The northeast tributary is a known site for coho spawning. s ·lough SA (Appendix A, Figure S1}, is approximately l.S miles in ~t.ngth . The initial 1/4 mile from the mouth upstream is influenced by the mainstem Susitna Ri ver and except during periods of extreme low flows, a backwater area is created in the slough. Above this the flow is free flowing except for be aver dams which are located within the middle section of the slough . Slough SA can be characterized as having sloping six-foot cutbanks and six 11 heads 11 which contribute flow from the mainstem except for periods of low mainstem dis- charge. During those periods, flow is generated through groundwater perco- lation and release from beaver dams. Sockeye and chum salmon were observed -199-_ ___..l. I ' DRAFT spawning in the lower stretches of the slough. Slough SA was the longest of the 5 s 1 oughs samp 1 ed and ex hi bi ted the greatest diversity. Transects were located only at the "head" and mouth of Sloughs 8 and 9 due to their length. b. Morphometry Data The survey data included head-pin and cross-section elevations, and longi- tudinal, diagonal and horizontal distances. w~tar $ edge locations and head-pin distances are illustrated in Figures 122-124 . Cross-sectional profiles of the slough mouth and head portion were also plotted (Figures 125-!40) t o provide a basis for illustrating the stage req tt ired from the mainstem to provide flow into the study sites. Head pi n and cross section elev~t i ons are presented in Appendix E. c. Stage/Discharge Data Stream discharge and stage measurements were recorded from June to September, 1981. Table 9 illustrates the stage changes versus time and discharge. The mainstem discharge as determined from the USGS gaging station at Gold Creek is presented in Appendix F to allow comparison of mainstem and study slough flows. -200- ~ Q :. z: ..... b -c..

The field parameters are available for the September sampling period. These provisional data ar~ presented in Table 10. Data from the mainstem at G~ld Creek and the rest of the September data are not yet ava il able thus no analys 1s has been made. Thermographs Two sets of thennographs were install ed to obtain surface water and intra- gravel temperature data. The instruments installed in Slough 19 were r emoved by a bear, thus only one set of data was obtained. The data illustrate diurnal temperature fluctuations, ranging from 4.5 -8.5°C, of the surface water and a constant temperature {3.0°C ) of the intergravel water. The intergravel temperatures were consistently 2°C below the lowest temperature in the surfac~ water {see Figure 141). -222- Tab l e 10 .

APPENDIX G METHODS SUPPLEMENT Water Qua 1 ity Water Quality was evaluated at the fishery habitat evaluation and selected habitat evaluation staff gage placement sites i n the study area below Devil Canyon and from the center of each index area in the study area above Devil Canyon. General habitat evaluation water quality data were collected twice monthly below Devil Canyon and once per month above Devil Canyon. Selected habitat evaluation water quality data were collected one time per seasonal period of low, medium, and high flows. Dissolved oxygen lDO), pH, temperature, and specific cond•.!ctance of surface waters were measured in the field with a Hydrolab model 4041 multiparameter meter. The instruments were operated following the manufacturers' instruc- tions and when applicable calibrated according to the procedures established by the USGS (1981). Water samples for turbidity analysis were collected at I the same time the preceding water quality field paramete-:-s were measured. Samples were collected in 250 ml plastic bottles filled two-thirds full and stored in a cool, dark location prior to analysis. Turbidity samples were returned to Anchorage at the conclusion of each sampling period for analysis on a Hach model 2100A turbidimeter. Air temperature was measured at these sites with a thermometer and shielded from the direct rays of the sun. ' DRAFT Surface \'latL•r temperatures were continuously monitored at selected sites by ~1od e l J -90 Ryan thermographs to identify thermal cha racteristi cs within the study area. In addition to surface water temperatures, intragravel tempera- tures were continuous l y monitored by thermographs buried in the gravel to characterize the relationships between surface and ground water temperatures at selected habitat locations . Hydrology ~lean column, point velocity, and depth measurements were measured with Marsh- r~cBirney, Price AA, or Pygmy flov1 meters and topsetting wading rods according to the respective manufacturers' instructions and procedures approved by the USGS (Smoot and Novak 1977; Buchanan and Somers 1973). Point velocities were measu red at the same depth as the organism (i.e., fish) or object (i.e. minnow traps, spawning redd, etc.} of interest. The mean column velocity is the measurement of the average veloci ty in the same vertical plane as the preceding point velocity. In water with a depth of 2.5 feet or less, as measured with a topsetting wadi ng rod, the mean column velocity was measured at the point located .6 of the total depth from the surfa ce of the water. For depths greater than 2.5 feet , two velocities were measured to compute the mean column velocity. They were meas ~red at .2 and .8 of the total depth from the surface of the water and averaged. When using a Price AA or Pygmy flow meter, the ve l ocity at the point of the current mete r was determined by counting the number of signa ls (11 clicks") per unit of time. Each meter was calibrated by the corrmercial supplier and an 2 ' DRAFT equation for the relationship between v< locity and revolutions per unit time was derived. To facilitate field use, the equation was solved for a number of revolJtions ("stop cou nts") and various time steps. A rating table (Figure 1) whi ch shows the velocity for a given number of revolutions per time interval was provided with each meter. The real trick in using the ra ting table was to memor ize the "stop cou nts ". One cot."lted clicks for at least 40 seconds, remembering to stop counting at one of the stop counts in the rating table. (Fail ure to do so would negate t he ability to obtain the velocity directly trom the rating table . One could not simply interpolate between stop cou nt values given in the table; the rating curve equation had to be solved). The rating table was usuall y constructed in one -second steps from 40 seconds to 70 seconds . When using a f1arsh -,.,d~.,rney electronic flow meter, the meter was set at the des ired wate r de pth and allowed to calib rate for 20 seconds prior to reading the meter . Locations of point and mean column velocity measurements included minnow traps, salmon redds, gill nets , and trot l ine sites. Velocities were also measured at sites where fish were observed. Minnow trap velocities were measured at the upstream mouths of traps each time they were set. Location and identification of salmon redds where velocity and depth were measured ~ere based on standards established by the ADF&G (Estes, Hepler , and Hoffm ann 1981) and the Arctic Environmental Information and Cata Center , AETDC (Bal dridg e 1981).

Polarized sun glasses were worn to screen out reflected glare from tr.e water and int:rease the observer's efficiency. Redds were defined by direct observation of the repeated fanning and digging actions of the female at the same site. Redds were located by observing character- istic spawning behavior including biting and chasing of intruders by a male - female pair , or a'l inci i vidual adult remaining over a distinct excavated depression in the s treambed. When a redd was located, the site was marked by methods similar to those used by Bovee and Cochnauer (197~). After all of the redds within a sampling site were identified, the velocities and depths were measured. Velocities at set gillnet and trot line sites were measu red at th ree equally s~aced intervals al ong the length of t he initial set wh en set perperdicular to the flow. When set paralle1 to the flow, one velocity measurement \'las taken immediately upstream of the net or trot line. Measu rements which were recorded were collected when the gillnets and t rot lines were let . [very attempt \'las made to obtain velocity measurements . When location of fish sampling gear and water depth made these meas uremen ts impossible t o obtain , this was noted on the point specific habit"'t evaluation f orm . Staff gages were install ed at fishery habitat and selected habitat evaluation sites in the stud)' an~a below Devil Canyon. Staff gages were read twice monthly, with the except io~ of side sonar and fishwheel site staff gages which were read every six (6) hours when the sites were manned by AA crews. 5 • • DKAFT A transect was s urveyed and the s tream bed profile determined in a plane p~rpendicular to the flow of water at each selected habitat gage site prior to ins talling a gage. Selected habitat staff gage e levations in t he study area between Ta 1 keetna and Devil Canyon were determined from the R&M Co n s ultants datum used to establish streambed elevations. The staff gage was read before and after collecting the selected hab,tat discharge data . This infonnation can be used to develop s tage/d ischarge rating curves. Wh ere app licable, mainstem di scharge information wi ll be obtaine d from the closest USGS gaging station a s a control . Discharge was measured at selected habitat l oca tions during three seasonal flow periods (high, medium, and l ow}. Th ese measurements and the f o ll owing discussion we re based on procedures developed by the USGS (Smoot and Novak, 1977; Buchanan and Somers 1973}, and USFWS Jnstream FlO'il Group (Bovee and Milho u s 197 8 ; Trihey and Wegner 1981). D1scharge was computed from the mean column vel ocity and depth infonnation recorded a t vertical columns (verticals) collected along t he transects sur- veyed when placing t he staff gages . A tagline was stretched across the water parallel to t he transect . One attempted to subdivide the channel such that no more than St of the total flow passed between successive verticals. The spaces be tween verticals were termed cells. Vertical s were placed s uch that they best descri bed velocity distribution and c hanges in tht! cross sectional channel geomet ry. If the direction of flow was not at right angles to the cross s e c t i on , the ve l oci t y vector normal to the section was located. The cosine of the horizontal angle (Figure 2} wa s me a s ured by hol ding the di s - charge measurement note s heet in a horizontal po sition with the point of 6 ' DKAFT origin (0) on the left edge over the tag 1 ine, bridge rai 1, or any other feature parallel to the cross section. With the long side ~arallel to the dlrcction of flow, the tagline or bridge rail would intersect the value of the cosine of the angle (a) on the top, bottom, or right edge. The measured velocity was multiplied by the cosine of the angle to dete rmi ne the veloc ity vector component norma l to the section measu red. Vel oc ity V e c t o r \ Fi gure 2. Neasurement of Horizontal Angles (from Suchanan and Somers 1973). Substrate data were collected based on procedures used by the AEIDC ( 198 1 ), ADF&G (Estes , Hep l P~, and Hoffmann 1981) and Shirazi (1979), at fis he r y 7 ' DAAFT habitat evaluation (point specific and general habitat) and selected habitat eva l uation s ites. Selected habitat eva luation substrate data were col l ected along the discharge measure ment transect(s) at each ve l ocity and depth measurement site. Point s pec1fic ha bitat evaluation substrate data collected from a 2 foot radius around veloc ity and depth meas urement site s . Su b s trate c l asses were assessed by se lecting up to three prodomi nant substrate groups and record ing the percent of each. The size and type of s ub s trate was grouped into t he foll owin g classes: 0. Organi c Detrius 1. Silt Clay 2. Sand 3. 1/16" -1/4" 4, l /4" -1" 5. 1" -3" 6. 3" -5" 7. 5"-10" 8 . 10" + 9 .

The s ub s trate 8 • • DRAFT clas~ification \-lithin each of these distinct areas wa s also identified and recorded on the map . Subst rate from each of these areas was photographed. Photographs were taken at each transect using photography pr ocedures similar to those userl by R&f·l Consultant s (Griffiths 1981). A 60 x 60 em grid subdivi ded into 5 x 5 em squares (Figure 3) or a ruler was placed on top of the substrate and photograp hed (Kel l erhals and Bray 1970 ; Griffiths 1981). An upstream view cross-sectional pr ofile map was drafted for each staff gage t r ansect (Figure 4).

QUALITY CONTROL A systematic approach fo r maintain i ng desired standards for the measurement of field panme t e r s wa s establ ished for the instruments used in this study. ThermometErs were perio:!ically compared to a National Bureau of Standards {NBS) standard thermometer for the range of t em peratures to be encountered . I f present , variations were noted and corr ection factors ca l c ulated and taped onto each thermometer. Thermographs were ca l ibrated by the ma nufacturer for temperature and timing. Operationa l thermograph s were periodically inspected in the field comparing the temperature and ti me on the c ha r t with the known ti mP and t emperature data. A ma rk wa s made on t he ch art at tha t poi nt . ~!J t er qua l ity instruments were periodically evalu dted by the USGS . ~Jheneve r · a question a rose conce rning qual i ty contr ol, the US GS, EPA , and man ufac turer of the data coll ecti on devi ce we r e co ns u lted. 28 DRAFT literature was periodicall y reviewed to insure that state-vf-the-art datJ co l lection and anaiysis techn iqu es were being observed. A hydraulic engineer was consulted to evaluate the accuracy of data collection and analysis techniqu e s. The USFWS was periodically consulted to evaluate the accuracy of instream flow data col lecti on and analysis techniques. The p r oject biometrician was consuited to evaluate the accuracy and statistical merit for co llecting data. State-of-the-art habitat data collection and ana lysis courses were attended when it was determined att~ndance will improve the quality of the program. Th e n~ld data we re .. eviewed periodically by the field biologist responsible for its collection . A brief narrative (trip re por t) was prepared upon re turning from the field summa rizing the habitat characteristics described by t~e data set. Any abnormal or intervening field con d itions or sampling probl ems which might have biased the data set are also to be discus sed in the narrative . Da t a Routing Raw data were returned by the field crews to the Anchorage Su Hydro office for copyin9 and filing at the end of each sa w.~l1ng period. 29 • • DRAFT LITERATURE CITED AEIDC. 1981.
