Escapement Monitoring of Some Naturally Spawning Columbia River Basic Chinook Salmon Stocks, 1987
As part of ongoing efforts to implement the 1985 United States-Canada Pacific Salmon Treaty, the found tribes of the Columbia River Inter-Tribal Fish Commission (CRITFC) in 1987 monitored nine substocks of naturally reproducing upper Columbia River Chinook Salmon for purposes of estimating their spawning escapements. Monitoring was done in eight Columbia River tributary systems in Idaho, Oregon, and Washington.
