Stamp winter steel start late Nov and run til end of March maybe into early April. So 250 estimated fish divided by 4ish months is 60 to 70 fish per month entering the river. I am sure back in the height of the winter steelhead fishing on the stamp there were times when at least 60 or 70 fish entered the river on a single high tide.
Arguing the numbers now is a mute point, it sucks and looks to continue to suck into the foreseeable future, likely never to return to anything resembling the not too distant past.
