Exactly one reservoir (or a number of tiny ones not worth mentioning), because even all the way from Richland to Portland there is hardly any elevation drop.

- usrusr 3y agoPS: oh, you meant reservoirs in contributory valleys left and right of the main river. Sorry about the misread, "above and along" should have been clear enough.
- s1artibartfast 3y agothis works for water storage, and some for hydro generation, but for hydro stroage, you really want two large basins with as big of a elevation change as possible. This is because dams are very expensive, have height limitations, and some inherent risk. Hover dam is only ~200 meters high. The big hydro storage projects have height changes ~400 meters.
