Single-Year Loss Thresholds

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 from 2010 through 2018 for each of:

Natural Winter-Run Chinook Salmon (loss= 1.17% of JPE)
Hatchery Winter-Run Chinook Salmon (loss= 0.12% of JPE)
Natural Central Valley Steelhead from December through March (loss =1,414)
Natural Central Valley Steelhead from April through June 15 (loss = 1,552)

(More information on 4-70)
