Here is the latest updated Columbia River upriver spring chinook run size by fisheries officials:
Bonneville Dam passage through May 5 totals 119,758 adult Chinook. Based on the 10-year average the 50% passage date is May 7, ranging from April 27 to May 12.
The U.S. v. Oregon Technical Advisory Committee (TAC) met Monday May 5 to review the status of the upriver spring Chinook run. TAC officially updated the run to a minimum of 185,000 adult fish. TAC will continue to meet weekly to review stock status and is scheduled to meet again Monday May 12.
Under the U.S. v Oregon Management Agreement, a Columbia River return of 185,000 adult upriver fish allows for a non-Indian ESA impact rate of 1.9% and a catch balance limit of 16,835 upriver mortalities. Commission guidance directs managers to allocate the impacts 70% sport/30% commercial. ESA impacts increase for runsizes of 217,000 fish or greater.
