Re: Red Feather Lakes
Red Feather has some really good fishing. There are numerous lakes up there, and also some small streams/beaver ponds.
The most popular lake is Dowdy, and its shorelines are normally filled with people in lawn chairs throwing their powerbait, so if you want to avoid that, stay away from Dowdy.
There's also Bellaire (Which I believe is the biggest?) and West Lake, which are also popular fishing areas for both lures/flies and bait fisherman.
If you're looking to fish with flies/lures, especially in a float tube, Parvin Lake is amazing. It's flies and lures only, thus giving it less pressure than the other lakes, and has some fairly large trout in it. Big browns, rainbows and also cutties and brookies are in there. They have signs for Tiger Muskie in there, but I've yet to actually see any evidence (Anyone ever caught one outta there?).
Other than that, grab a map and do some exploring. There are a lot of smaller waters up there, and many of them have fish.
