Dikes- that is the Army core of Engineers, local diking districts and FEMA. It is all backwards economics.
Forestry practices- DNR (with some science help from WDFW. In fact, WDFW has been pushing for greater buffers. This is on public and private lands
Agricultural impacts- State Ag and Ecology- whenever any change is proposed the legislature threatens to defund ecology
Groundwater and surface water withdrawals- Ecology and now local planning offices after recent court cases
Culverts etc- DOT
Wetlands- local planning, Ecology and EPA. Mostly local planning
Shoreline reg's- local planning and ecology (ecology approves local reg's)
Dams- FERC, NMFS and others
The only thing WDFW really does is harvest (sport and cowboy commercial) and hatcheries. Honestly, I used to think hatcheries were a big problem. I no longer do. I think there are issues with harvest because of them at times. If you look at the amount of hatch fish in the PS, it's hard to say they are limiting anything. On the coast? I don't really think so with the exception that they allow for harvest of wild fish at hatchery rates and bi-catch etc.
The problem as I see it is that people say that WDFW is in charge of the fish. Fish runs are down. So, it stands to reason that WDFW is to blame. The thing is, WDFW has no real power over anything habitat wise. They are in charge of harvest and hatcheries.
