Current River Flow Updates

Latest update: 6/16/2022--

Flow rate and water temperature has been great in 11 Mile lately. Dries, nymphs, and streamers are all still in play. Classic tailwater options will work great for nymphs and dries- any small/sparse midge or mayfly imitation in #18-22 will make up the bulk of your fly box. Parachute adams, griffiths gnats, Jujubee midges, zebra midges, massacre midges, RS2's, etc. are a few go-to's here. Streamers are working too- bugger and baitfish style patterns in #4-8 are preferred. These suggested patterns are listed below in our "Recommended Flies" section!

Historical River Flow

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.

Seasonal Conditions

In the Summer Months, 11 Mile Canyon sees an abundance of bug life with key hatches being midges and baetis.
