Fly Fishing Denver

Does anyone know a good place for fly fishing in the Denver area?
I know that mountains are a good place, but I'm looking for a creek or stream or something (in the Denver metropolitan area) where I can practice my skills beginner. Suggestions? Thank you!
Although if the lakes, here's a list for you to start. Hope this helps. Good luck!
