Definitely commerical (tribal and non-tribal) over harvest. Lots of rivers and spawn beds but like /\ said, no fish. Look at places in Alaska and B.C. Salmon are/were doing very bad in some places with pristine habitat yet fish are in danger. What was the one thing that B.C. did to revive it's salmon fishery? Did it have anything to do with habitat? NO! They drastically cut back on commerical fishing.
