The Rio Costilla, the main fishery in the Valle Vidal, is a medium size tailwater springing from the bottom of Costilla Reservoir in Vermejo Park. The Rio Costilla is loaded with Rio Grande Cutthroats averaging 8 to 12 inches, and some much larger.
It runs through beautiful, wide-open high mountain meadows, making it a superb stream for beginners.
There are several ponds and lakes nearby as well. Some lakes have an abundance of fresh water shrimp which the large Cutthroats gorge on. These are the places for float tube fly fishing at its best!
