Greetings from Boulder,CO!
Colorado keeps giving these sunny windy windows of decent fishing between spats of snow and cold. If you can cast in the wind and don't mind getting cold the fish seem pretty aggressive, and the lack of crowds has the fish less spooked.
Last week in Boulder, 16" brown and many smaller fish including rainbows.
Friday night tailwater fishing, 24" brown (estimate 8 lbs. it was a fatty!) and too many 15-19"ers to count
Sunday in a narrow canyon on the front range, 16" bow and many others.
Tuesday at some bass/carp ponds East of Boulder, 15" largemouth on a crayfish pattern.
To the OP: I found a local lake that has walleye, I tried stripping streamers along a rocky shore one very windy day. This seem like nice large fish to fight with a fly rod... Mind if I ask what you use for Walleye? I'm guessing large/medium sized streamers still. Do walleye hang in the shallows? Deep? Rocks, grass? got some google searching to do, but I am looking forward to fishing for Walleye in Colorado at some point. Kind of new here, so I apologize If I have just totally missed previous posts on 'Walleye on the fly'...
Anyway, if you are dying to fish, and your local water is frozen, maybe a trip to sunny CO could cure your blues.
