As a resident of the Pacific Northwest, I think there is a lot of untapped Hydro potential, especially in places where there aren't any fish runs. Of course, some of them are pretty remote, but there's a lot of untapped kinetic energy going to waste.
The thing that gets me, is that a lot of the power for the Portland area comes from fossil fuel-powered plants. Not because there are a lack of hydroplants, but because most of the power that's being generated along the Columbia is sent via HVDC along to California. I don't particularly like being the battery for LA, since all the money goes to the Federal Government (DoE/Corps of Engineers). Let them build their own plants.
