Survival rates are high going downstream, can the salmon get back upstream or are there no fish ladders past some point?

- intrepidhero 6y agoThe big dams on the upper Columbia do not have fish ladders. Although Grand Coulee did have one during construction. I've been looking for data on survival rates for upstream fish... but a brief search hasn't turned up the data I was looking for.
