Spring Chinook Run Forecast
• Columbia Basin Management Decisions are Based on Annual Run Predictions
• Harvest Regulations above and below Bonneville Dam
• Harvest Allocation for Treaty and Non-treaty Fishers
• Science from Yakima Basin may Assist in Refining the Predictor Model

• Why has the traditional jack predictor resulted in increased divergence between
forecasted and actual returns in recent years?
• Can we correct for this?

Jacks (as sampled at Roza Dam/Yakima R.) were much bigger in 2008 than in

Adjusting the predictor model for these two variables results in much greater
forecast accuracy for years since 2001
