Some perspective from those that’ve seen these rivers for several decades would be great.

Are these conditions approaching historic levels? How did the salmon react in previous times? Just trickle in until at some point their biological clocks couldn’t wait anymore and then just a mad rush through shallow water? Any effect on the returns 3-4 years later?

Scenarios like this are what I wish WDFW had in mind when allowing a 2 fish non-select harvest on Coho this fall. Could really burn escapement if it gets bad enough.
