I read the same article and thought man is that guy gonna confuse some folks!!! From Aug1 through Sept 30 you can keep 2 adult salmon on the Cow in any portion of the river as long as they are not chums or wild Coho. After Oct. 1 you must release all Chinook between Blue Creek and Mill Creek. Follow Aunty's link and the regs are pretty clear. I think I will send an e mail or phone the guy who wrote the article on Monday and maybe He'll retract it next week.
Good luck and tight lines, Jeff
