Eleven Mile Fly Fishing Report

Latest update 2/4/16: Eleven Mile Canyon is feeling the full effects of Colorado winter. Most of the lower canyon is locked up in a thick layer of ice but the upper section towards the dam is flowing low and clear. I strongly recommend paying attention the weather forecast if you’re planning a trip up the canyon. Extremely low temperatures combined with a nasty wind rolling off the lake can make for a frigid day of fishing. IF temperatures cooperate, fish can be found at the heads of deep pools on shelves and in shallower riffles and buckets a the sun warms the water. Fish will stack up in these areas to feed on midges and other tailwater fare. I’d mostly likely be fishing a 6mm chartreuse Trout Bead trailed with some type of darker midge pupa or emerger such as an RS2 or a zebra midge. You may find some fish feeding on top and a small parachute adams or an Eric’s Hi-Vis Midge will do the trick.

River Information

Eleven Mile Canyon is another very popular and productive spot to fish along the South Platte River. Approximately 2 hours from Denver, this tailwater section of river created from 11 Mile Reservoir, holds Rainbow, Brown and Cutthroat trout. Fish numbers are very high in the first several miles below the dam and the river is abundant with aquatic bug life. This river sees some phenomal BWO, midge and PMD hatches providing exceptional dry fly fishing at times.  12"-18" fish would be considered average here, however fish much bigger than this are taken every year- especially within the first two miles of the dam. Given it's proximity to Denver, angling pressure can be quite high here, however the fish are typically still quite catchable. 



Hatches

winter/spring: midges, baetis

summer: mayflies, tricos, stoneflies, caddis, terrestrials

fall: midges, mayflies, tricos 


Seasonal Conditions

With flows hovering just around 170cfs, 11-Mile Canyon should be fishing great for the foreseable future.  There should be consistant hatches of BWO's, Midges, Caddis and small Stones which will  have the fish feeding.  Attractor patters like Stimulators, Royal Wulffs and Humpy's will also work well, 
particularly as the fish begin to see bugs consistantly on the surface.  Nymphing will continue to be a productive method of fishing, primarily during midday when bug activity slows.  Mornings and evenings will offer the best dry fly fishing as air temps will be the coolest during this time of day.  
Riffles and faster moving water will be ideal spots to fish, especially when bugs are hatching.


River Access

11 Mile Canyon is best accessed via US Hwy 24 in Lake George. Once here, take Country Road 96. Stay to the right at the fork in the road. There is an entrance station which is manned during the day. A self service fee tube is also availble for after hours. The park is generally accessible year round.
