Fisheries managers say upriver Columbia River spring chinook return unlikely to meet preseason expectations

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.
