Predictions

Arrival distributions, historical timing, transport, and survival for various Snake River yearling chinook, steelhead, subyearling chinook and sockeye stocks. Forecasts are based on PIT Tag detections at Lower Granite Dam.

Arrival distributions and historical timing for combined stocks of yearling chinook, steelhead, subyearling chinook, sockeye, and coho. Forecasts are based on Passage Index data at each dam, individually.

Arrival distributions and historical timing for yearling chinook, steelhead, subyearling chinook, and sockeye. Forecasts are based on Chelan PUD passage counts at Rocky Reach Dam.

Arrival distributions, historical timing, and survival for specific Snake River and Upper Columbia River ESU stocks. Forecasts are based on selected PIT Tag detections at McNary Dam.

Arrival distributions and total run size for spring and fall adult chinook at Bonneville Dam. Arrival distributions are forecasted to upstream dams for four stocks: Snake River, Upper Columbia River, Lower Columbia River, and Hanford Reach/Yakima. Forecasts are based on visual adult passage counts at Bonneville Dam.

Water temperature and total dissolved gas percent at various dams in the Columbia and Snake rivers. Forecasts are based on observed temperature and total dissolved gas percent data at each location.
