Your on the right track. Utilizing the escapement reports by week you can compare years as long as the hatchery production remains the same. Take Satsop Late Coho at Bingham you just compare years so this years is showing larger returns just compare it to each of the previous years to get a better view of things. This only gives you a general idea but it is a tool. The Wynoochee trap reports year to year are the same type of tool and when coupled with the spread sheet on escapement I set out to folks again you can get a flavor for how things are going. If you want the spread sheet just PM me and I will get it to you.

So Late Coho 2021 Jan 13 (same week for 2022 ) 1290H 35W 5J 2022 2750H 115W 10J. Then you have realize the ocean survival play a roll but you can look at Normal timed Coho for % reference on plus or minus. Looking at the numbers normal timed Coho over performed the preseason predictions but nothing like we are seeing with the Late Coho minus harvest. The wild number at 328% over 2021 is eye popping.

DW tracks the Wynoochee trap reports and last time we talked about this issue it was very similar to what Bingham's was showing for Coho. Steelhead not so much as this year lags behind last year.
