About this water

The Dream Stream is the meadow tailwater between Spinney and Eleven Mile that grows big run-up rainbows and browns and draws every angler in the Front Range who's heard about them — which is all of them. It's open, clear, technical sight-fishing, and on a good hydrograph it can be extraordinary. It can also be a parking lot. Two honest cautions come with this water: the crowding is real enough that a perfect release doesn't guarantee a good day, and the spring and autumn spawning runs bring out behaviour that's better left alone. Fish the run, not the redds.
