Eleven Mile Fly Fishing Report
Latest update 12/1/2016: Eleven Mile Canyon is another great winter fishing option. Flows are a very good for this time of the year holding at 84.7 CFS. This will help reduce some of the usual spooky tendencies for fish this time of the year. Midges and Baetis are going to be the main course meals for trout in the canyon this time of the year. However, leading with a bigger attractor nymph like a san juan worm or a stone fly pattern will entice a few fish throughout the day. Also don't shy away from lengthening your leader and fishing to pods of risers if you see fish consistently sipping. Go to patterns here are going to be Griffiths Gnats sz. 20-22, Sprout Midges sz. 20-22, D Midges sz. 20-24, Red Copper Johns sz. 20-22, Rainbow Warriors sz 20-22, RS2s sz. 20-24, Tube Midges sz. 20-22, wd-50s sz. 20-22, Zebra Midges sz.20-24, Black Beauties sz. 18-24

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.
Match the Hatch

Like all stretches of the South Platte, Elevenmile Canyon is another great piece of water to spend a Fall day on. The crystal clear waters of this canyon can provide some incredible sight fishing opportunities with both dries and nymphs on any given day. Streamer fishing can also be quite good in here as well- particularly on cloudier days.
For consistant activity I recommend nymphing unless you see fish actively feeding on the surface. Look for fish to still be holding near the riffles and shallow shelves, buckets, drop-offs and rock gardens.
Bug life here will mirror most other stretches of the Platte with the PMD/trico/caddis game slowly fading throughout the season. However, as these bugs disappear you can expect baetis and midges to take their place so match your flies accordingly. As is always the case on this river, cover water and don't spend too much time in an area if it's not producing.
