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.

Tips & Other Information:

Anglers should prepare themselves for sporadic hatches of midges.  The optimum window of opportunity is between 10:30 a.m. and 3 p.m.  Eleven Mile Canyon is known for its excellent midge hatches this time of year.  Make sure you are carrying plenty of brown and black pupae and several adults to match the hatch during the height of emergence.  Its important to target the slow, deep pools where the trout overwinter. The best fishing is up near the dam as the lower part of the canyon freezes during the winter. Make sure you dress warm…Eleven Mile Canyon is a frigid place during the winter.
