State, federal and tribal biologists have upgraded their forecast of the Columbia River sockeye run to 400,000, a four-fold increase from the initial prediction.
An update on the summer chinook run is expected Tuesday, however counts at Bonneville Dam are consistent with the initial forecast of 93,300.
State biologists reported on Thursday that approximately 52 percent of the summer chinook are fin-clipped. Since nearly 90 percent of the upper Columbia summer chinook hatchery fish are fin-clipped, the 52 percent mark rate is a sign the run contains a significant number of wild fish.
Sockeye return to the Wenatchee and Okanogan rivers of north-central Washington, plus a small number to the Snake River watershed in central Idaho.
