ADF&G USGS USGS ADF&G Alaska Power Authority ADF&G TES R&M R&M R&~1 R&M TES TES TES Jim Gill opened the meeting by introducing key project personnel in a.ttendance. He reviewed the meeting objectives and mentioned the review studies completed so far and planned for 1980-81. He also stressed the need to set up coordination procedures for ~groups involved in the downstream river (_Watana to Cook Inlet) studies on the Susitna River with special attention on fisheries habitat, vegetation, and instream flow studies. ITEM 2 Woody Trihey, a special consultant to Acres, reviewed the draft FERC license requirements as outlined in the Federal Register on February 2, 1981, in terms of downstream river studies on the Susttna River. Pertinent sections of the Federal Re.g_ister are i"ncluded as Attachment A. t4r. Trthey explai'ned that FERC would be looking for a general description of the project, i.e. setting, locale, nature of the project, as well as discussion on the project's potential ACTION BY [ L [ [ r [ L E [ [ [ c p L ~:~ 6 E c L r: 8 [ effect on existing uses of flow in the Susitna. Baseline data collected during the study should describe nonnal and seasonal variability in streamflow and water quality. With this information the long and short term effects of the proposed project on the natural variability_of background streamflow conditions can be explained. Mr. Trihey felt the baseline data collection currently bei·ng carried out on the river was adequate for the first phase of the study and initial license application in that the project effects on the normal and seasonal variability of stream flows can be described. As more specific infor- mati"on is obtained on instream flow uses which may conflict wi·th the. proposed hydro-:-development additional data collection and analysis can be incorporat~d into later work phases. He stressed that there is no requirement by FERC that the initial license application be based upon a detailed environmental analysis, but the application must be complete and comprehensive. Meaning that the magnitude and consequences of the proposed development needs to be considered with respect to all other existing/competing uses for streamflows in the project area. In addition the license application must describe actinns which could be undertaken to mitigate any adverse impact associated with the project. The mitigation plan must be prepared in consultation with State and Federal Agencies. The FERC "'!ill review the license application, request an outside review oy appropriate State and Federal Agencies, then decide on its adequacy. When FERC determines the license application is deficient they generally provide the applicant with a statement of what additional data, analysis, or inter-agency consultation is required. - 2 ACTION BY It was ~1r. Trihey's opinion that a license application could Acres/TES be submitted in the spring of 1982_, but it would be returned to the applicant with the statement that considerable additional work would be required in several areas. ITEr~ 3 r~r. G. Krishnan of Acres, Buffa 1 o opened the next section of the meeting by outlining hydraulic and hydrologic projects completed by Acres/R&~1 team during the first year of the feasibility study. These included the fall owing: -Compi.lation of his tori cal streamflow, cl imatol ogi ca 1 and water quality data on the Susitna River Basin. -One year of climate and hydrological data collection in the oasin during 1980. -Freezeup and breakup observations on the river. l:lydrographtc surveys completed in the reach from Talkeetna to Deadman Creek. ~, [ [ f' l~ [ [ -, [: c._. ·~ ~ L: I c~ ~~ I. -Regtonal flood analysis showing relationship of flood peak and flood volume, and recurrence in the Susitna Basin. -Preliminary report on Subtask 3.10-Lower Susitna Studies addressing pre and post project flows and flood peaks based on either a one or two dam scheme. He added that future analysis downstream will be based on the flows from a two dam scheme. Brent. Drage from R&r1 Consultants fo1l owed with· more detailed description of work items completed to date by R&M on the Susitna River. Attachment B is a summary of this description. Bob wn liams, a consultant working with Terrestrial Environmental Specialists (TES), explained TES's role 1'n the first phase of the Susitna project. They are currently compiling an. extensive literature review on fish species as applicable to the Susitna River system which should be available to project personnel by mid- summer. They have also provided input to Acres on selection of dam development plans, access route, and transmission corridors. Christopher Estes suggested they coordinate their fishery literature review with the ADF&G fish habitat preference literature review project supervised by Rich Cannon. He also requested a copy of the bibliography, listing all of the literature reviewed. Milo Bell, also working' with TES, described several literature reviews he has prepared in connection with this project including one on dissolved nitrogen studies in rivers. He is currently working on an extensive liter- ature review on the effect of silt on fisheries. Copies of this review will be made ava.ilable to interested project personnel when it is completed. Chri stophe.r Estes and Tom Trent from ADF&G concluded this section of the meeting bypresenting an outline of the fisheries studies to be conducted on the river pri"marily from Talkeetna to Devil Canyon. The field program has been designed to better define the relationship between various fish species and habitat in terms of water quality, substrate, and streamflow parameters. In addition, numerous staff gages will oe installed throughout the project area in order to identify those habitat areas where problems may occur due to flow regulation. - 3 ACTION BY Acres/TES TES Acres/TES -·~ ""' ;_;_;i __ji ...;; -~ ~ ~-ii ~J Christopher reminded Acres of their committment to supply Leitz Levels and an electronic distance finder. Bob Williams verified that John Hayden has agreed to this. Estes also referenced a November 30, 1979, letter to Eric Yould on this subject. Jim Gill said he would follow up on this. A procedures manual is being developed describing the specific data to be collected outlining the three elements of ADF&G's Phase I program: anadromous. adult study group, resident juvenile fish studies, and the aquatic habitat study group. Further discussion of this program was continued under Item 4 of the meeting agenda. The meeting proceeded to discuss the Acres/R&M water quality program as being conducted in the light of ooservationsmade by Tom Trent in a memo to APA (Attachment C). Krishnan briefly traced the development of the water quality program as currently being carried out by R&M citing the meetings last year with representatives of USGS, ADF&G, APA, DNR, TES, R&M, and Acres. Bob Madison of USGS stressed the point that the methods of USGS and. R&M for water quality sampling were not comparable. It was difficult, however, to say how the sampling procedure affected the anlaytical resu 1 :ts. Chris top her Es-tes emphasized the need for the compatability of results of the R&M and USGS observations so that R&M could compliment and extend the USGS historical records. He also stated that 1t would be logical to insure that the same paremeters be evaulated at each sampling·site as discussed in the memo from Tom Trent to Dave Wozniak (April 15, 1981). Dana Schmidt indicated that the vJQ parameters presently measured by R&M are adequate for purposes of preparing the initial license application and Phase II study plan; hence expansion of the present WQ data collection program is not necessary at this stage. After some discussion it was agreed that: la) R&M wi·ll call ect depth integrated WQ samples and three surface samples during their nex·t field observations at Gold Creek and analyz.e the two samples. The results would be evaluated jointly with USGS to determine the comparability of the two sampling procedures. - 4 ACTION BY Acres Acres/TES/ ADF&G [ [ [ [ c [ ! - I . -~ D u r = f.? l.-.P t I = L~ u l~ (_b) Brent will set up a meeting with USGS personnel to determine the sampling schedule and analysis tech- niques which will be followed to resolve the present question concerning incompatability of WQ data. Christopher requested that the APA·consider funding the Chulltna water quality program, with the understanding that R&M and the USGS would resolve the comparability issue, adding that the Chulitna data would be of value to all study participants. Jim Gill said APA would have to· make the final decision on the Chulitna water quality monitoring. ITEM 4 During this segment of the meeting, each of the agencies involved gave a short description of their 1981-82 field programs and analyses to be undertaken. Mr. Krishnan began. by outlining the proposed Acres activities for the comming year. Four key tasks were described: (a) Water Surface Profile Modeling Water level and discharge observations made during 1980 field program along wi{h river cross section data in the reach from Talkeetna to above. ~Jatana dam site gathered during hydrographic surveys is presently being computerized for input into the HEC-2 water surface profile model. This model will be"used to estimate water surface elevations during the open water seasons for various stream- flows at different sections along the river. The model is proposed to be calibrated using 1980 obser- vations and will be independently verified with 1981 data. The model will be used to predict water levels under pre and post project flows under open water conditions. (b) Ice Modeling Ice observation carried out during freezeup and break- up will be used to calibrate an ice model developed by Acres to simulate ice cover formation, stability, and thickness in the river reach. An associated backwater profile program will use the information from the ice simulation model to predict water levels for ice cover conditions under pre and post project conditions. - 5 ACTION BY R&M/USGS Acres/APA R&M/Acres Acres [ f~~ r~ L [ [ [ [ [ [ u [ c c L [ L [ ~ ~ (~} Reservoir Modeling Both HEC-2 and ice modeling wi 11 be carried out in the reservoir pools to determine the upstream effects of various water-levels in the reservoir. Ice cover formation on the reservoir, its behavior, and stability will also be evaluated with respect to various reservoir operations. (d) Reservoir Temperature and Sediment Modeling It is proposed to use HEC models for temperature and ·sediment modeling of the reservoirs. The prime objective in using the models will be to arrive at multilevel power outlets that may be required to con- form to environmental requirements as to temperature and sediment concentration in the downstream flow. There is essentially scant data available on river water temperatures and sediment loads. Data from the continuous water quality monitor near Watana Camp will be used as supplement to historical and 1980 data collected for input in the models. Correlations where possible will be made between observed long-t~tm air temperature and water tem- peratures fo extend the data base for analysis. A reevaluation of the extent of mathematic modeling is under way in view of limited base line infor- mation available. (e) Morphological and Sediment Yield Studies These were discussed by Brent Drage (R&M). For morphology studies below the dam sites the river will be divided into two parts -Susitna River upstream of the Chulitna River confluence and the river downstream of the confluence up to the mouth. Regime type relationships will be developed for the upper, more stable part of the river, above the Chulitna confluence. Once these regime relationships are developed for natural flow conditions, sediment discharge and flow parameters can be altered to identify possible changes in river characteristics such as gradient and channel width under regulated flow conditions. Significant problems of aggradation or degradation if expected to occur will be addressed. The river downstream of the Chulitna confluence is a more complex situation and much less historical data is available. Reports such as the Subtask 3.10 Preliminary Open Water Report provide some - 6 ACTION BY Acres Acres R&M [ r~ ,- [ [ L [' "' [ t 1: w ~ c [ F = [ l l~ b l~ guidelines for problem identification and further studies. The analysis carried out will be refined as more data becomes available and also extended to address needs of environmental groups for such tnformation. Bob Lamke of the USGS was asked about the status of a USGs· bedload measurement program for the Susttna. He explained that their-three year study for bedload, bed material, and suspended sediment data collectton was being negotiated with the Alaska p·ower Authority. Bill Emmett (USGS, Denver, Co.) is being consulted on developing the program based on his previous experienc~ in sediment transport and discharge on other Alaskan rivers. Bob Lamke did feel that it would not be possible to get geared up to begin data collection this summer. The aquatic studies program was outlined by Christopher Estes (ADF&G). Five locations are to be selected as representative of the reach between Devil Canyon and Chulitna confluence. At these selected sites substrate and water quality data will be collected at three times during the year based on seasonal discharge changes and will include pH, dissolved oxygen, specific conductance, water temperature, and turbidity measurements. Hater samples will also be taken in the sloughs for more detailed analysis by the USGS. This wHl permit the ADF&G to compare the water qualtty/discharge relationships beb.reen the mainstream river and sloughs, thus adding further importance for all water quality data collected to be comparable. ADF&G need some tnput from R&M on selection of five typical reaches. Brent Drage wi 11 get together with Christopher Estes for finalizing the reaches. Numerous staff gages will be installed at sampltng sites in the side channels or sloughs of. interest for habitat studies and readings collected at varying intervals (from 3 times daily at selected sites to twi.ce weekly at others) to correlate water levels in the main stem with those in the· se 1 ected s 1 oughs and channe 1 s. Periodic discharge measurements and water velocities will be carried out at several sites to refine - 7 ACTION BY Acres/APA ..

Joint crews consisting of representatives from the adult anadromous section, resident juvenile section~ and aquatic habitat section will work on the river from Cook Inlet to ~Jatana · collecting the information outlined above, as well as maintaining fishwheels, sonars, and thermographs to be set up at several locations along the river. These fisheries studies should characterize and identify locations of typical fish habitat areas for different species, improve our present under- standing of fish movement in the Susitna River system and provide some initial insight as to responsiveness.of the various habitat types to changes in stream flow. From the data collected it would be possible to answer questions like how readily are the side channels or sloughs watered and dewatered, are they relatively stable or subject to rapid changes, etc. Woody Trihey stated that the final product from ADF&G Phase I field program should be an initial characterization of typical fish habitats in the· project area and uti 1 i zati on of these habitats. Knowing this and post project stream flow conditions TES could provide initial comments pertaining to the generic type of impacts that might occur to the various habitats due to the project. The final review of the 1981-82 program was presented by Bob Williams (TES). He explained that last year TES identified 50-60 impact issues associated with different phases of the project. During the coming year, they will take information generated by other involved agencies and apply it to the various impact issues. The detail of the impact analysis will be based on the relative importance of the issue as time and budget ~onstraints prohibit addressing all issues in great detail. A composite list of impact issues is included in the TES Procedures Manual produced last year, and a more detailed list will be available soon. Kevin Young (Acres) should follow up to obtain the details. Literature survey will be continued for species of salmon. Reviews are nearly complete for Chinook and Coho salmons; others are still being developed. - 8 ACTION BY TES/Acres TES TES/Acres I [ [ [ [ t ..--., =-~ I. 9 b r L~· f c [ I L~ L f = L" l~ Mr. Williams stressed that reports submitted toTES must be in good final form following the approved Acres• format as there is no time available for TES to do any rewriting. It was-agreed that TES will supply Krishnan with a detailed description of hydraulic and hydrologic information that is required for the:ir analysis and evaluation. A similar list should be drawn up by ADF&G as well. This will enable producing timely data/information to meet needs of different agencies. A p-lan for coordinating and channelizing information exchange among the study team members was discussed. It was concluded that Woody Trihey and Dana Schmidt should form the focal point of all field data collection and hydraulic analysis and information. Jim Gill would keep in touch with the progress. All corres- pondences should be copied to Kevin Young to continue coordination of all efforts in the environmental studies. , - 9 ACTION BY Acres/ADF&G TES/ADF&G/ Acres Acres/TES /? /) /~'1)~ Reported by G.

UJ C\1 ~ 0:: a.. a_ ;2 <t. ~ The present USGS and R&M Su Hydro Hater Quality sampling programs for sites on the Susitna River downstream from Devil Canyon (figure 1) have been reviewed by my staff. Inconsistencies with the types and level of analysis will prevent comparison of these sites for hydrologic appraisal of the overall lower Susitna Basin. Following is a summary of the existing USGS and R&M water quality program and our recommendations for improvement. According to the present USGS work plan, sediment samples are analyzed by particle analysis (Attachment 1) and suspended sediment at the Gold Creek Site; whereas the samples at ;he Sunshine site are analyzed to the sand break (Attachment 2). In addition, the water quality analysis at the Sunshine site is more comprehensive than the Gold Creek site (Attachments 3 and 4). · R&M is collecting water quality data above the proposed dam site and at Gold Creek (Attachment 4). There are three ba~ic differences between the R&M and USGS sampling and analysis schemes: 1) parameters; 2) methods of collection and preservation; and, 3) methods of analysis . Parameters The differences in parameters being analyzed are: USGS measures suspended sediment and R&M measures settleable solids and total suspended solids. These are not comparable (Madison 1981). The. specific nutrients which USGS and R&M measures are different. The USGS will measure a broader range of inorganic cations and anions than R&M. Collection and Preservation The differences between the methods of collection and preparation are significant and make comparison of samples questionable if at all possible at 3 stations. R&M composites 3 grab samples which are collected 1 foot under the surface across the river (right and left bank and center channel) (R&M 1980), whereas USGS takes a depth integrated composite sample at several points along a transect across the river. The USGS depth integrated method accounts for differences in concentration which will otherwise result if a sample is collected in too shallow of water or the water is stratified and not homogeneous, thus give a better representation of the river water Quality. The 3 R&M surface arab samoles mav not be sufficient .. ~ r~ l.-~ r-~ [ t ' [ [~ [ ~~ I .. -4 c c c. ~ E [ r L~ B [ D=ve ;...;czr.iat; - 2 -April 15, l 981 techniques for nutrients are not the same; thus, data comparison is questionable. ~ Analysis The methods and level of analysis used for trace metals by R&M are different; thus data comparison is questionable. With this wide variety of differences in sample collection and analysis, comparison of the USGS data which are collected on the Chulitna and Sun- shine Stations to R&M data at their Gold Creek stations would be inadvisable. USGS concurred with us concerning the advantages of modifying their program (attachment 1) to permit comparative analysis. It was also their opinion that a coordinated uniform hydrologic appraisal of the lower Sl,!sitna Basin. would be beneficial to the overall Su Hydro Feasibility Study Program. In addition, the USGS suggested that ·the· Chulitna River station be included in this proposed revised sampling and an~lysis scheme because of its proportionally high contribution to the Susitna· River and potentially significant influence on water quality and channel geometry (Attachment 5). ~ A summary of the suggested revisions to the USGS program currently funded by the APA and R&M program follow: Gold Creek USGS Modifications WATER QUALITY* present: change to: / USGS mini-USGS compre- mal and hensive R&M data SEDIMENT* present: particle. size change to: -::- .· ! : j:;. ·.- ~- ' Sun- shine USGS com- rehensive __----·-//~and . ~.r:._e_ak -~-'.\~ particle size Chulitna none USGS com-Oo prehensive particle size *examples of minimal and comprehensive water quality and particle size and sand break analysis are attached. /: Estimated additional costs to the existing APA/USGS cooperative sampling program to implement these changes would be: :..,.~---'"c.o_ .! -, j ., -~ :c:! _j -, ·--" =-> ~ c,.l ... To enable the use of R&M data for comparison purposes wlth existing and historical USGS data, uniform data collection and analysis procedures which are approved by USGS should be adopted by R&M. R&M and USGS Ev4luation The Steering Committee should reyiew the overall USGS and R&M water quality and hydraulic sampling and analysis procedures to evaluate the validity of the existing programs and determine whether they - are integrated. It is our understanding that the only Su Hydro study participants which are presently required to author procedure manuals are TES subcontractors and the AOF&G. We strongly support the changes to the USGS program and believe they will benefit all study participants. With respect to the Department of Fish and Game•s use of this information, it will be evaluated to assess the-present relationship between discharge and water quality on the river and eventually used to determine the physical and chemical changes which will occur with changes in flow regimes if the proposed dams were constructed. Therefore we suggest and request that these minor changes to the existing USGS APA program be adopted and funded by the APA. Madison, B. 1981.

At the confluence with the Chulitna and Talkeetna Rivers, the Susitna River changes abruptly from a meandering single channel configuration to a predominantly braided pattern. Upstream of Talkeetna to the proposed damsites, the Susitna River is being studied quite extensively under Subtask 3.06 -"Hydraulic and Ice Studies 11 and Subtask 3.07 -11 Sediment Yield. and River Morphology Studies 11 • Downstream of Talkeetna, a reconnaissance level study is being carried out under Subtask 3. 10 . A prime objective of this interim report is to quantify, as best as is practical, the potential changes in the flow regime during floods. Vegetation and habitat study personnel indicated that estimates of change in water levels during various floods would benefit their programs. There are currently only two stations that have existing hydrologic data; Susitna River at Sunshine and Susitna Station. At these two reaches, the river is constricted into a single channel which is not representative of the predominantly braided river pattern. With respect to potential changes in water levels during various floods under pre and post-project conditions, these two stations would probably reflect the extreme case. Therefore, a third station was added to this study which would represent the flow regime in a braided reach. A sample section was selected 8,000 feet down- stream of the Willow Creek confluence at the Delta Islands. This -~1 I -, -,.-' I -, __, ~ __, - ~ -~ . ...- 9 - -~ -=== ~ -~ _ _. _3 .] ~I cross-section was synthesized from a reconnaissance field trip and hydraulic regime relationships which enabled estimating hydraulic characteristics under pre and post-project conditions. With three sections in the Lower River, it is possible to interpolate the following results to intermediate locations of interest. ·- j -. .J . .

J --"' J J ] 2.2 -SuiTIJiary Variances in flow and-stage in the Lower:-Susitna as a result of flow regulation are reasonably bounded by this analysis for open water floods. The magnitude of change for pre and post-project floods of ·2, 5, 10 and 25 year recurrence interval can be estimated from this analysis. Since the data base is scant, the procedures utilized in this study were basic and perhaps oversimplified. However, generally the assumptions made were conservative and reflect higher changes in flow and stage than may occur. A summary comparing each station is presented on Table 2. 1. At Sunshine, the stage in the river is expected to be J.Z to o.8 feet lower during floods with a recurrence interval of 2 to 25 years. At Susitna Station, a change in" stage for the same flood intervals could vary from 1 • .3 feet to f.~ feet. Comparing these two stations to the Delta Island Station shows that the potential - decrease in stage for a braided section would be less at just below 2 feet. Since the rivers width increases more with an increase in stage, this is expected for a braided reach. Based on these three points, estimates of post project stage changes could be made for intermediate river reaches. Sunshine is representative of an upstream constriction, Susitna station represents a narrow downstream section, and the Delta Island is representative of a broad braided reach. Therefore, other river reaches would have stage changes equal to or less than Sunshine or Susitna station and equal to or greater than the Delta Island section, depending on the characteristics of the river reach being considered. Local variances in river reaches and effects of debris jamming, transitional -channel changes and other natural influences could distort these results. However, for the purposes of establishing 1·"2. ~~ I • ....... ..;u " 0 ...... . .. ., d " &~ u ,., ~~:;] t .. ~·!~' ~ ~.

Additional field data, that is scheduled to be collected during the 1981 open water season, should provide sufficient information to carry this study through another degree of refinement.
