Because we wanted to further investigate the relationship between natural escapement and hatchery supplementation, we conducted cross correlation between pairs of time series where both natural escapement and hatchery return estimates were available for the same taxa. The pairs evaluated were: Total numbers of fall Chinook spawners (natural escapement + hatchery returns) in the basin vs. fall Chinook returns to both hatcheries, spring Chinook natural escapement to the Salmon River vs. spring Chinook returns to TRH, spring Chinook natural escapement to the Trinity vs. spring Chinook returns to TRH, late fall Chinook natural escapement to Blue Creek vs. Chinook returns (both spring and fall runs) to TRH, and summer steelhead natural escapement to Salmon vs. steelhead returns to IGH.
