The Tribes improved fish habitat in Agency Creek by placing in-stream structures. The reach to be enhanced is approximately 1.5 miles in length and is located between Yoncalla and West Fork Agency Creeks. Habitat structures would be created using large logs or trees and boulders in several locations in this reach. Approximately 90 logs would be placed in complexes of 3-7 logs, with a goal of 40-60 logs per mile. Large diameter logs with a length adequate for the stream channel would be used to ensure that placed logs are stable and provide habitat for as long as possible. When possible, logs with root wads attached would be used. Structures would be designed and placed to maximize the benefit to fish by creating and maintaining pools and complex channels and providing cover. Log placements would take place in 2004 during the instream work period of July 1 to October 15. The Tribes would begin planning for the enhancement work in 2003. Existing stream survey data for the reach would be evaluated to assess current stream channel conditions and needs. Site visits would be made to determine the placement and locations of structures. Based on the outcome of evaluating the current channel and site visits, detailed site plans and costs would be developed. At this time the final number of logs and structures would be determined. Log structure design, location, and placement would follow the guidelines of A Guide to Placing Wood in Streams published May 1995 by Oregon Department of Forestry and Oregon Department of Fish and Wildlife. The project would follow the Oregon Aquatic Habitat Restoration and Enhancement Guide and would follow the timing guidelines of the Oregon Guidelines for Timing of In-water Work to Protect Fish and Wildlife Resources. Additional technical support would be sought from experts with Oregon Department of Fish and Wildlife.
