Summer chinook and sockeye runs to the Columbia River will be smaller than forecast, state and tribal fish biologists said on Monday.
The Columbia River Technical Advisory Committee downgraded the chinook run from an initial prediction of 73,500 to 60,000 and the sockeye run from 180,500 to 155,000.
Summer chinook pass Bonneville Dam from June 16 through July 31 and are headed for several tributaries in north-central Washington. Sockeye are headed mostly to the Okanogan and Wenatchee rivers.
The biologists will meet again on July 8 to refine the forecast.
