Description: Little Su weir:The Little Susitna weir is located at river mile 32.5, approximately 4 miles upstream of the public use facility off Point MacKenzie Rd. Escapement is primarily monitored using a resistance board weir. An underwater video system is installed within the weir and motion-detected fish passage is recorded during nighttime hours and at times when the river is heavily glaciated. The river is a strong producer of coho, chum, and pink salmon and a moderate producer of king salmon. Salmon fishing is allowed from its mouth upstream to the Parks Highway.

Sustainable Escapement Goal for Chinook: 2,100 - 4,300
Sustainable Escapement Goal for Coho: 9,200 - 17,700 (Graphed above)
