The purpose of these reports is to present the progress of a study program designed to assess the effect of a large impoundment (Brownlee Reservoir) on the passage of anadromous fish stocks, primarily chinook salmon Oncorhynchus tshawytscha and steelhead trout Salmo gairdneri.  The program has been pursued under five major areas:  1.  The limnology of the reservoir system, 2.  the migration of adult salmonids through the reservoir, 3.  the recruitment of juvenile salmonids to the reservoir, 4.  the migration of juvenile salmonids through the reservoir, and 5.  the escapement of juvenile salmonids from the reservoir.  This research was conducted simultaneously and is reported upon in separate sections by senior biologists in charge of each study.  In addition, close cooperation and liaison were maintained with other state and federal agencies doing allied work in the vicinity or actively participating in certain phases of the program.  These include the Oregon Fish Commission, Oregon Game Commission, Idaho Department of Fish and Game, Bureau of Commercial Fisheries River Basins Studies, and the U.S. Public Health Service.
