I was just up at Red Feather today. Ice was 10-12" and the stockers were eating.
Boyd is really popular and has a pretty large variety of species.
You can fish a lot of the park ponds in fort Collins. I know city park has stockers and some perch. Other ponds have bluegill, bass, etc. You cant fish any of the state wildlife ponds though, like riverbend or arapahoe bend ponds.
