Dworshak Kokanee Salmon Update - August 2016

Sean Wilson, Research Fisheries Biologist in the Clearwater Region, finished their annual trawl survey the last week in July on Dworshak Reservoir.  Survey results indicated high kokanee salmon densities and larger than average size (10 - 11") - which he attributes to our BPA funded nutrient enhancement program.  As the adult fish prepare to spawn, they are migrating up the reservoir with most fish from Gold Creek to above Grandad Bridge.  There are still good fish numbers near Magnus Bay and Dent.

Kokanee are just starting to show a hint of the changes they go through at spawning time.  Snout are starting to "hook" and a hint of red can be seen on the bodies - but flesh quality is still very good for eating.

Kokanee are a land-locked sockeye salmon.  Like their ocean-going relatives, their bodies undergo a colorful transformation (green head and red body) before they spawn in the fall and die.  Decomposing carcasses provide vital nutrients for the young fish to grow and continue the cycle of life.  They provide a great opportunity for fish viewing in the fall on tributaries to Lucky Peak, Arrowrock, Anderson Ranch, Ririe, Deadwood and Dworshak reservoirs, Lake Coeur d'Alene, Payette Lake and Lake Pend Oreille, as well.
