The Technical Advisory Committee who oversee the Columbia River fisheries met today to review the upriver run size and concluded:
The upriver spring chinook run is unlikely to meet the preseason forecast of 314,200 fish at the river mouth.
Flows at Bonneville Dam have been over 400kcfs during April 26-29, with 46-percent of the flow coming from spill.
Based on the 10-year average, the 50-percent passage date is May 6 (range April 24-May 12).
Fish counts at Bonneville Dam in recent days looked promising for spring chinook, but have since plummeted. Here is a look at the numbers:
April 23, 4,376; April 24, 4,873; April 25, 2,427; April 26, 1,382; April 27, 781; April 28, 603; April 29, 823 for a total return to the dam of 21,558.
