Columbia River Sockeye Return Surges and
by Mark Yuasa
While one updated salmon forecast has been downgraded, another one continues to exceed state Fish and Wildlife's prediction.
The Columbia River Technical Advisory Committee met yesterday (July 6) and updated the chinook and sockeye run sizes.
The updated summer chinook run size is 58,000 at the Columbia river mouth, compared to the preseason forecast of 70,700. This is based on average counts from now through July 31 at Bonneville Dam, and an estimated below Bonneville harvest of 5,100 chinook.
The group also increased the sockeye run size to 190,000 at the river mouth, compared to the preseason forecast of 183,800. This forecast is based on an average run timing curve. The preseason forecasts was 183,200 sockeye.
Through July 6, 167,593 sockeye have been counted at Bonneville Dam, and at McNary Dam, 100,278 sockeye have been counted.
