Steelhead in southern California have been known to be resident through years of drought. Enough water returns and they smolt.

Folks now are regulalry documenting resident males spawning with anadromous females (successfully). In some situations in WA (late in spawning season), the only males that are spawning are resident as the anadromous males have all finished.

Are humans so convinced that we know it all that we know the Elwha residents won't migrate so we have to import fish for recovery. It's been close to century that the dams have been in. We can't wait a reasonable amount of time to see how nature reponds?
