South Platte River: Eleven Mile Canyon

Difficulty Intermediate
Ideal Days To Fish 3/8, 3/9 & 3/14

Weekly Report

Report DateMarch 4, 2021
Flows are healthy and stable in Eleven Mile Canyon, but with the recent flow reduction on the Dream Stream, we wouldn’t be surprised if we see Eleven Mile Canyon flows follow suit in the coming days. With that in mind, we highly recommend hitting the river while flows are still up. Mornings have been slow but mild afternoon temperatures have brought trout to life. Midge pupa/emergers have been hot when trailed behind small midge larva, flashy attractors, Mini Leeches or scuds. Mercury Black Beauties, Top Secrets, Jujubee Midges, Mercury Midges, WD-40s and Chocolate Foam Back Emergers are must have pupa patterns. Spend most of your time picking apart deep pools and runs but don’t ignore transitions, slow riffles, shelves and faster seams during the afternoon. With 40 degree weather in the forecast this weekend, keep an eye out for midge hatches and surface activity. Griffiths Gnats and #24 Parachute Adams are great dry fly patterns right now.

Detailed River Info


The Eleven Mile section of the South Platte is a gorgeous stretch of river that offers anglers amazing fishing year round. The canyon experiences some great hatches throughout the warmer months and because it's a tail water, it can be fished in the winter. As you explore this river you'll notice that it has blended characteristics of the Cheesman Canyon and Deckers sections of the South Platte. While the best fishing usually occurs within two miles of the dam, the road that parallels the river makes it easy to jump in and out of the car to explore different sections. Eleven Mile has quickly become one of our favorite places to fish.


The Eleven Mile stretch of the South Platte offers a wide range of features that caters to any style of fly fisherman. The canyon sections of the river provide deep pools for the streamer junkie and the nymph fisherman who likes to sling around a lot of weight and drift flies down deep to try and catch a picture worthy fish. Other sections of the river remind us more of Deckers with medium depth riffles, runs and tail outs. Considering this section is a tail water, the standard South Platte flies are the way to go. Classic examples are size 18 - 24 RS2's, Top Secrets and Zebra Midges. Other than the beauty, our favorite part about this river is it's ease of access and the ability to fish 2-4 sections in a day. Our favorite thing to do is drive up close to the damn, fish a quarter mile section, jump back in the car and move down river until we find another quality section to fish. No need to haul around a big back pack either! With the road so close to the river, you can access your lunch and river beers with ease! 

River Access

The Eleven Mile  section of the South Platte river is easy accessed from County Road 96. County Road 96 is a dirt road that starts in Lake George and runs along the river up to the dam. The road consists of pull-offs and designated parking lots making it easy to jump in and out of the car to fish different sections of the river. One thing to be aware of is the $7 entrance fee that needs to be paid to enter the canyon. Plan on bringing a check or cash to pay this fee.
