When is the Best Time to Fly Fish in Colorado?
Colorado offers fishing year round. With that said, there are some times of year that will have better catch rates than other times. Some of the waters will freeze over in the winter, but ice fishing may still be offered. Obviously in the winter months it is quite cold to be out there fishing, so you’ll need to dress appropriately.
Basing your fishing on the hatches is always a great idea so here are some tips to keep in mind. If you're heading to the Upper Colorado River you'll want to go in early June when for the Salmonfly hatch. If the Fryingpan is your destination then aim for mid-August all the way until October when the Green Drake mayfly hatch. If it's the Arkansas River that you are going to check out April through to May is ideal as that's when there are some serious Caddis hatches.
Although not everyone enjoys winter fishing, there are still opportunities to enjoy it in Colorado and the fish are still hungry. Advantages include off-season pricing and much less crowds.

For nymphs consider the juju emerger, San Juan worm, prince, and gold-ribbed hare's ear.
