Eleven Mile Fly Fishing Report

Latest update: 10/20/18 -- Flows in 11-Mile Canyon continue to be really good for this time of year. They are currently at 112 CFS. As long as this continues, it should be a place you consider if you are in the area especially with the Zooish like crowds at the Dream Stream. BWOs and Midges are going to be the dominate food sources right now. That means RS2s, Black Beauties and things along those lines with be the most productive nymph patterns. Also don't shy away from dry flies and streamers. Both can be productive at times, so if you begin seeing noises tie on a combo of a BWO and Midge dry. As for streamers, why not? If you find yourself in the middle of a slow stretch, give it a shot. You might be surprised.

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.

Seasonal Conditions

Like all stretches of the South Platte, Eleven Mile Canyon is another great piece of water to spend a Fall / Winter day. This section of the Platte often gets overlooked this time of the year as the Dream Stream commands so much attention. The crystal clear water 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.

Fishing here in the Winter is going to follow the weather trends. Fishing will be most productive up near the top of the canyon where the water will be warmer. 

For consistent 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.

Don’t shy away from stripping streamers in the lower canyon stretch as well. As cold weather slows fish down, they are eager to grab a big protein meal in the plunge pools.

Bug life here will mirror most other stretches of the Platte with BWO / Midge showing up throughout the season. 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.
