caught a ton of carp and trout in that area.
I'm guessing your variety of Carp didn't have whiskers? Those would be Largescale Suckers, in no way related to Carp, and they are actually Native.
Carp and Suckers come from a totally different family, Carp - Cyprinidae and Suckers - Catostomidae, two totally, unrelated fish, although some may disagree just because they have a mouth that points downwards :wall:.
Not trying to shoot you down, just wanting to educate others that what they are catching from the Santiam is not 'invasive'.
They do look like Carp when your floating over deep holes in an inner tube from Greens Bridge to Jefferson, I believe some of those are monster Squawfish as well.
