United States Department of the Interior FISH AND WILDLIFE SERVICE P.O. Box 1287 Juneau, Alaska 99802 (907)586-7240 Mr. William A. Cbrbus, Manager Alaska Electric Light and Power Company 134 N. Franklin street Juneau, Alaska 99801 August 06, 1985 Dear Mr. O>rbus: The u.s. Fish and Wildlife Service (FWS) has reviewed the draft • Al;plication for New License for the Annex Creek and Salmon Creek Hydroelectric Project,. FERC Project No. 2307,· as prepared by the Alaska Electric Light and Power Conpany (AELP). We offer the following comnents: General Comments: Generally, the draft appears to be an adequate review of the proposed action. Some of the issues could be expanded to better address future demands which may be placed upon Salmon Creek. In recent years, the drainage has been involved in sustaining the Twin Lakes recreation area, a salmon hatchery, an increasingly popular sport fishe~, and most recently a Borough water supply system. The projection of relative impacts of power generation in relation to total inpacts, both present and future, would be of interest. The documentation of the preliminary project review and interagency coordination suggests only limited interaction with federal agencies. Should any dispute arise on discharge regimes, inadequate federal coordination could necessitate further evaluation. §pecific Cbmments: Page B-8: Paragraph 3: The text indicates that releases from the upper power house will be made during periods of low flow in order to maintain the level at the staff gage at 1.4 feet. FWS believes that the 1.4 staff gage reading should be used to reflect a required discharge of 9 cfs. The staff gage reading should be adjusted as a result of channel fluctuations or contour changes in the streambed or if discharge is insufficient to inundate spawning beds. If discharge should fall below below 9 cfs, a new staff gage value should be established to reflect 9 cfs. Cooperative monitoring by AELP, ADFG, NMFS, and FWS would assure adequate habitat protection. Page E-4, E-6: The text indicates that no wetlands exist within the project boundaries. This is incorrect since the creek beds are considered wetlands that would fall under the jurisdiction of the Clean Water Act.
Page E-ll: The text states that analysis of streamflows from July 1982 to September 1984 indicates that natural streamflow in Salmon Creek often drops to 0 cfs during cold winter spells. FWS believes that the extrapolation is inaccurate. We have no record nor is there evidence to suggest that Salmon Creek has ever been an intermittent drainage. Page E-15: The text states that during the Januaroy 17, 1985 scoping meeting, the only concern identified was the need to develop an operating plan to avoid excessive releases into Salmon Creek. FWS records indicate that other concerns were brought up, including the maintenance of minimum flows to protect spawning habitat. It was announced that David Hoopes and ADFG biologists would walk the lower portion of the creek to identify areas of required habitat protection. Rick Reed, ADFG, cited FWS jurisdictional interest and expertise in the establishment of instream flow criteri~. Page E-20: FWS recommends that a monitoring program be established to ensure that operational procedures do infact provide adequate inundation of spawning habitat. Page E-19, Table E-3.2: Mammals: Silver-haired bat, bushy-tailed wood rat, coyote, and lynx are not common in the area. Birds: This bird list should be revised with more recent information since many species listed are rare or accidental. We recommend Armstrong R.H. 1984, A Guide to the Birds of Alaska, Alaska Northwest Publishing conpany, Anchorage. Summary: We believe that the draft is generally acceptable. We recommend that minimum flows be referenced to a discharge of 9 cfs, the value of which would be reflected by the stream gage reading of 1.4 feet. We further recommend participation of resource agencies and the applicant in a monitoring program to assure sufficient water quantity and quality in winter and to prevent ramping of discharge water from release valves. cc: NMFS, DNR, ADF&G, Juneau R.W. Beck, Seattle FWS-ARD, Anchorage Sincerely, ~··~~V . /U1---~~ ~~-.-__ ~N(r Field Supervisor
