Eleven Mile Fly Fishing Report
Latest update: 8/19/2017: We can't complain about the current flows in the canyon right now. We have been taking two approaches to the canyon lately. The first method is fishing a Hopper-Dropper rig. They have been really successful as of late or two dry rigs, a Hopper or Stimulator, with a small Trico as the trailer. If you are fishing dry droppers the biggest factor of your success will be covering water. Don't find yourself sitting on fish because they will generally move to the dry withing the first 5-10 casts. If you can't get away from all the fish you see stacked in the runs. If you are nymphing, big attractors and various caddis combined with a healthy mix of small black emergers is a great place to start. RS2s, Juju emergers, Trico Spinners have all gotten it done this week.

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.

Like all stretches of the South Platte, Elevenmile Canyon is another great piece of water to spend a spring day on. This section of the Platte often gets overlooked this time of the year as the Dream Stream commands so much attention. 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.
Fishing here in the spring is going to follow the weather trends. Fishing will be most productive up near the top of the canyon early in the spring. As the weather warms later into spring, fishing will improve further down the canyon.
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 warm spring weather brings the river back to life, fish 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/Caddis 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.
