Large Columbia spring chinook run forecast
SALEM -- The Columbia River could see a return of 470,000 spring chinook in 2010 -- the largest since 1938 -- if the forecast of the technical committee advising Columbia River fishery managers holds true.
The forecasted run is up significantly from last year's final run of 169,300 fish, officials said.
Because of challenges in forecasting the spring chinook returns in recent years, members of the Technical Advisory Committee had to reconsider the model they have used in past years to predict the number of returning fish, the group said in a statement.
Stuart Ellis, current chair of the committee and fisheries scientist of the Columbia River Inter-Tribal Fish Commission, said committee members were leery of the record number of spring chinook jacks counted at Bonneville Dam in 2009.
Forecasts relying heavily on jack counts from the previous season had overstated the actual return of adult fish by an average of 45 percent.
An accurate preseason forecast is necessary to set commercial and recreational harvest levels that meet treaty obligations under U.S. v. Oregon and conservation mandates to protect fish runs listed under the federal Endangered Species Act.
Ellis said this year the committee considered several additional models that took into account other factors such as ocean conditions.
