Awesome, I have a view of the McNary dam on the Columbia from my window. Keep up the research! Let us us know what you find.
Do you think he will use the fish ladder or go for it and go over the top with all the water they are spilling to flush little salmon downstream?
For those out of the area, the 13 dams on the Columbia dump about 1/3 of the annual flow over the spillways each year instead of making electricity with it on the theory that it helps little salmon get to the ocean. It does kill adult fish in the river by increasing the dissolved nitrogen in the water and the fish get bubbles under their skin that rupture and infection sets in.
State law says hydropower in not renewable so our hills are littered with turbines to meet the mandate of 20% renewable power sometime in the future.
