I should have said that it isn’t a river in Colorado that I recognize. Wasn’t trying to say it was the Colorado River.

Yes, there are some dandy Kokanee in Colorado. I think Eleven Mile reservoir is the location of the state record and I think it is over 6 lbs, but I have been gone for 20 years. Blue Mesa has Kokanee, as does Granby and Green Mountain. CDOW/CPW used to give away limits of Kokanee from their spawning operations.
