Wenatchee River Salmon Escapement Estimates Using Video Tape Technology in 1991

Abstract

Accurate determination of escapement is necessary for fish stock status analysis. In an effort to devise more accurate salmon escapement estimation techniques, a time-lapse video tape recording system was installed and operated from 22 April through 23 September, 1991, in the fish counting station at Tumwater Dam on the Wenatchee River. This was a continuation of studies conducted in 1989, and 1990.
