United States Department of the Interior IN REPLY REi=E:M TO: ~. i "',"J - • • ~ ! ,.: ~'.'\J ~~ ,:~ 1'~:;5;.A ~;',:t:.:n. 'W!mlt Sara Hunt 400 Willoughby Avenue Suite 400 Juneau, Alaska 99801 FISH AND \VILDLIFE SERVIC=: p.o. Box 1287 Juneau, Alaska 99802 May 22, 1985 Re: ADL 51675 Certification No. 611 Salmon Creek Dear Ms. Hunt: We have reviewed your request for comments on the Alaska Electric Light and Power Company's (AEL&P) application for a chanqe of appropriation of water. The U.S. Fish and Wildlife Service (FWS) has met with Dave Hoopes of R.W. Beck and Associates, Inc., representing AEL&P in the relicensing coordination for the Salmon Creek hydroelectric project. Mr. Hoopes has worked closely with the Alaska Department of Fish and Game (ADFG) in establishing a minimum acceptable flow for the creek. On April 29, 1985, biologists from the FWS and The National Marine Fisheries Service walked the lower portion of the creek up to the staff gauge. The staff gauge indicated a water depth of 1.5 feet. The staff gauge was in poor condition, but did not appear unstable. At a depth of 1.5 feet, all areas that we exaJnined which appeared to be of potential importance to anadromous fish were floooed. Previous field work by the Division of Commercial Fisheri.es indicates that the recorded low flows of 1985, corresponding to 1.4 feet at the staff guage, were sufficient to protect all documented s-pawning habitat within accessible portions of the creek. Although this figure reflects a very low flow for this creek, we will concur with ADFG. Because changes in channel contours and elevations of natural drainages occur over time, we believe it is necessary to correlate the minimum acceptable depth with a value in cubic feet per second (cfs). He understand that AEL&P has obtained a range for this value using discharge data from the u.s. Geological Survey. The amount of discharge at 1.4 feet depth varies between 7 and 9 cfs. Because of this variability and because of our concern that spawning beds remain inundated throughout the winter, it is appropriate that the higher figure serve as the standard. Should there be changes in the course or contour of the stream, a new staging gauge value should be selected which corresponds to a discharge of approximately 9 cfs. Of additional concern is the national record of fish loss which results when flow levels are not adequately monitored. Monitoring is absolutely critical if minimum flow standar.ds are to have any value. Monitor.ing and proper regulation must also insure that excessive water is not dumped from the Salmon Creek Dam.
Our corrnnents to the Federal Energy Regulatory Cornnission for the relicensing of this hydropower project will include the following recorrmendations. The licensee shall: ]) Provide a permanently enclosed staging gauge to be established by survey. 2) Require a minimum staging gauge depth of 1.4 feet which will reflect the corresponding discharge of 9 cfs. Should the physical character of the stream bed change such that 1.4 feet is no longer reflective of a 9 cfs, a new staging gauge valve would be established. 3) Develop flow management operational plan which will ensure that minimum flows are maintained at all times and that -dumping- of impounded water will not occur. We appreciate the opportunity to cornnent on this action. Sincerely, Field Supervisor cc: FWS-ARD-HR, Anchorage AEL& P, Juneau R.W. Beck and Assoc, Inc, Seattle
