While I certainly am no fan or the current WDFW management of anadromous fish, just what can they actually control?

Habitat? That's county and city rules for allowance of development.
Hydro? That's the feds (FERC)
Marine Mammals? That's the feds, too.
Predatory birds? Da Feds again through the Migratory Bird Treaty
Fisheries? Withe the Tribe's concurrence they can control the non-indian fisheries in WA. Tribal, BC, and AK gets back to the feds.

WDFW had very tiny hammers in this game and this is before Tribal donations to politicians get factored in.
