I can belive it. I lived in that area and fished that part of the river a lot. I never did see any oversized fish released, but many keepers and lots of undersized fish released. I think a keeper has to be between 36-60", under and over must be released unharmed.
They regularly catch 10-12' sturgeon in the nearby Columbia River and take pictures and release them. It's easy to see how a bottom feeder can get that big in the Willamette R., when the lamprey eels are running up to spawn, there are millions of dead eels floating in the river, and the sturgeon gorge themselves. Also a big shad run, spring Chinook, and the usual carp and panfish keep plenty of feed floating around the bottom. I'll betcha that's not the biggest sturgeon in the Willamette. Wonder if I went to school with any of those guys? Were there any names mentioned in that email?
I have a jig with a face like this!:eek:
