Effects of Iron Gate Dam Discharge and Other Factors on the Survival and Migration of Juvenile Coho Salmon in the Lower Klamath River, Northern Califo - Paperback

by U. S. Department of the Interior (Author)

Current management of the Klamath River includes prescribed minimum discharges intended partly to increase survival of juvenile coho salmon during their seaward migration in the spring. To determine if fish survival was related to river discharge, we estimated apparent survival and migration rates of yearling coho salmon in the Klamath River downstream of Iron Gate Dam. The primary goals were to determine if discharge at Iron Gate Dam affected coho salmon survival and if results from hatchery fish could be used as a surrogate for the limited supply of wild fish.
