Re: Avon, Colorado
Just my $.02 but call some of the shops up there. The Eagle might very well be frozen solid by the time you get there.
The Blue is open year round. You might find that below the reservoir through town is combat fishing if you go at the wrong time. Winter it is usually not as crowded but can be. If you can get some open water downstream of the outlet malls the crowds tend to thin out down there, but the fish are still nice.
Most guys congregate right under the dam of Dillon Reservoir in hopes of landing one of the many 20"+ rainbows sitting there eating mysis shrimp.
Might also be worth it to see if the Colorado River at the Pumphouse recreation area is open too.
