Windmills could be the solution for our hatcheries. They could generate power for the pumps, lighting, and housing for the workers. The blades would serve to kill the coumorants that kill the smolts.
Could try this out at the Sol Duc and Bogey/Calawah hatcheries.

I've heard that they are going to install tidal turbines on Admiralty inlet. Might be a problem for the fish.
