Records of Kvichak River spawning ground observations for Lake Iliamna and Lake Clark in Bristol Bay, Alaska began in 1920. Bureau of Commercial Fisheries (BCF) agents conducted ground, boat, and to a lesser extent, aerial counts or surveys of a number of spawning areas over the period 1920-1938. During 1939-1955, except 1942 and 1943, BCF personnel established a program of systematically surveying a group of index areas within the Kvichak system which obtained a yearly escapement index. From 1955-1987, except 1984, the University of Washington, Fisheries Research Institute (FRI) conducted systmatic spawning ground surveys in the Kvichak system. The number of stream, pond, and mainland/island beaches surveyed increased considerably in relation to earlier years. Due to funding cuts in 1988, aerial suveys of the Kvichak system were taken over by Alaska Department of Fish and Game, Division of Commercial Fisheries personnel. ADFG has flown the surveys from 1988-1998. The purpose of this report is to document and archive 1955-1998 Kvichak River spawning ground aerial survey estimates in a readily accessible format...
