Current River Flow Updates

Latest update: 10/23/23

11 mile canyon is flowing at 54 CFS and has been fishing quite well. An indicator rig has been working well as of late. Use a smaller worm, egg or mini leech (#14-16) as your point fly trailed by a smaller midge or baetis imitation. RS2's, chocolate thunders, pheasant tails and black beauties are all great choices in an #18-22. Expect to see BWO's hatching particularly on cloudier afternoons and come prepared with dries to match. Parachute BWO's in an 18-22 are an excellent choice.

River Information

11 Mile Canyon is one of Colorado's most famous trout fisheries in every way possible. As a fishery that boasts more than 3,000 fish per mile and is known as one of the most scenic stretches of the South Platte River, you can assume that these trout are seeing some sort of angling pressure 365 days a year. The rainbow trout, brown trout, and cutthroat trout that call this river home are not the easiest fish to entice. Make sure you have a large assortment of small midges and baetis patterns for the winter months and shoulder seasons. Summertime in the canyon can produce some of the most abundant dry fly hatches you will ever see in your lifetime. No matter what time of year you will be fishing 11 mile canyon, tippet selection will make or break your success. Small tippet sizes for both nymph fishing and dry fly fishing will increase your chances of fooling these fish to eat a fly. One of the biggest keys to success in the canyon is your eyes. Make sure to have a good pair polarized sunglasses and use sight fishing to your advantage.
