Elevenmile Canyon Stream & Fly Fishing Conditions on the South Platte River in Colorado

The South Platte River below Elevenmile Reservoir is absolutely beautiful. The South Platte River tumbles and twists through a majestic canyon as it carves its way downstream to the small community of Lake George. Parts of the scenic canyon remind you of the fabled Cheesman stretch while others look much like the renowned Deckers area. Elevenmile Canyon is a great winter and early spring fishery with tremendous opportunity to consistently hook nice fish. The river is loaded with Rainbows and Cut-bows with the occasional brown trout.

The average fish ranges between 12 and 17 inches and are strong as an ox. Occasionally you will hook fish between 17 and 24 inches in the upper reaches below the dam. The river is comprised of riffles, runs, shelves, gravel bars, and nice pocket water. The scenery is fabulous with logjams, huge granite boulders, fallen trees, waterfalls, and bald eagles soaring above the canyon’s lip. The ideal flow for Elevenmile Canyon is between 150 and 250 cfs. The best fishing is in the upper two miles. The aforementioned two-mile stretch is flies and lures only. This section is catch and release and all fish must be returned to the water immediately. Pinch down your barbs and protect this incredible resource.

Eleven Mile Canyon is known for its superb dry fly fishing. The Trico hatch is one of many that anglers should concentrate their efforts on. Mark Adams photo

Tips & Other Information:

Eleven Mile Canyon is fishing fair to good right now. Anglers can expect to see reliable hatches of midges, Tricos, and blue-winged olives.  Nymphing with an assortment of midge and mayfly nymphs has been productive before the hatch.  Matt’s Midge,  CDC Biot Trico Comparduns, and Mathew’s Sparkle Duns are effective during the height of the hatch. Dry and droppers are a good option right now with the heavy aquatic vegetation that is clogging the substrate in many areas.
