Biffchan, based on these numbers for the last 5 years, it's a conservative guess of 30,000 Cohoes expected to return this year. Some runs currently hold large numbers of Coho. BP posted a great report..

I'm still hooking into chrome fish which indicates late arrivals. It's wonderfull to know that these fish are still in the system.
