Current estimates generated by the Loss and Salvage Predictor tool. Predicts loss and/or salvage of endangered steelhead and winter run Chinook salmon at the CVP and SWP pumping facilities at the southern end of the Sacramento-San Joaquin Delta. Available Decemer to mid-June.
Single-Year Loss Thresholds (PA 4-69)
In each year, typically January/February, Reclamation and DWR propose to avoid exceeding an annual loss threshold equal to 90% of the greatest annual loss that occurred in the historical record 2010-2018 for each of:
