Upper Cowtitz and Taco Power/WDFW

Does anyone know if they (Tacoma Power/WDFW) trucked fish up this spring to spawn in the upper river, or does that only occur in the fall?


edit: nvm, google FTW! https://www.mytpu.org/tacomapower/fish-wildlife-environment/cowlitz-fish-report.htm
They released 180 spring Chinook adults and 110 jacks into Lake Scanewa above Cowlitz Falls Dam and released 192 spring Chinook adults and 88 jacks into the Cispus River above the mouth of Yellow Jacket Creek.
