摘要

The Klamath River Basin, including Blue Creek, a major tributary to the lowerKlamath River, has historically supported large runs of chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (O. mykiss). The watershed has been altered substantially during the past century and particularly during the last four decades. During this period, anadromous salmonid fishery resources have severely declined. Reductions in the quantity and quality of instream habitat, as well as in the population sizes of salmon and steelhead, have coincided with expanded logging and fishing operations, construction of roads and dams, water export, mining, and other development (U.S. Dept. of the Interior, 1985). The USFWS Coastal California Fisheries Resource Office in Arcata, California submitted a five year study proposal in 1989 to the Klamath River Basin Fisheries Task Force to evaluate the status of fall chinook and their habitat in Blue Creek. Work has been ongoing since that time with the final report and recommendations proposed to include data and results from FY 1993.
