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 2010-2018 for each of:

  • Natural Winter-Run Chinook Salmon (loss= 1.17% 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)
