Description: Chinook salmon escapement is monitored on the South and North fork of Anchor River beginning early-May through early August. The South Fork watershed is approximately twice the size of the North Fork. Escapement is primarily monitored using a resistance board weir on the South and on the North Fork. An underwater video system is installed within each weir and motion-detected fish passage is recorded 24 hours per day seven days each week. In some years if high spring flows prevents installation of the South Fork weir, a DIDSON sonar maybe used early in the season until flow subside.

Sustainable Escapement Goal for Chinook: 3,800 - 7,600 (Graphed above)
