Description: A 420 kHz dual-beam sonar system has been used since July 1987 to estimate the riverine abundance of chinook salmon Oncorhynchus tshawytscha in the Kenai River. In 1995, following a one-season comparative study, the dual-beam system was replaced with a 200 kHz split-beam sonar system. Daily abundance estimates of chinook salmon were generated from 16 May through 9 August 1995. The total seasonal estimate of 66,220 chinook salmon was comprised of 21,884 early-run and 44,336 late-run fish.
