OK theres been sturgen recorded in the chehalis since the late 1800s as well as the hoquiam river. So I have a hard time saying there columbia fish. Maybe Theres old stories of these monster fish being hooked while fishing for salmon. and scaring them. When my Dad was a kid in the 40s all he talked about was fishing for these fish, and there was lots of them, in the cosmopolis area all the way up to the black river. But as anything else logging and nets ect has pretty much done them in.. But they have been in there for many years, there recorded go to the libary and look at the history of grays harbor. I was told by an old timer there was a small springer run up till the 70s
