South Platte River: Eleven Mile Canyon

Difficulty Intermediate
Ideal Days To Fish 4/9, 4/10 & 4/12

Weekly Report

Report DateApril 8, 2021
Considering the recent bump in flow on the Dream Stream and the fact that Eleven Mile Reservoir is sitting at 97% capacity, the odds that we see an increase in flow through Eleven Mile Canyon sometime over the next few days is high. So, if you have your sights set on fishing Eleven Mile this weekend, keep a close eye on flows and be prepared to make adjustments. Until flows increase, anglers should focus on the pronounced sections of the river during the morning and faster moving water during the afternoon. Slow riffles, transitions and pockets have been a blast and highly productive during the warmest hours of the day. Along with baetis and midge larva, larger patterns such as leeches, eggs, scuds, Pheasant Tails, Guide’s Choice Hare’s Ears and Rainbow Warriors are solid lead patterns. For your trailer, keep it simple with midge pupa and baetis emergers. Black/olive RS2s, Mercury Black Beauties, Chocolate Foam Back Emergers and Jujubee Midges are hot trailers right now. Similar to last week, keep an eye out for surface activity between 11 am and 4 pm. If flows increase, water clarity will decrease, trout will adjust their holding positions and large and/or flashy lead patterns will be key.

Detailed River Info

Background:

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.

Angling:

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.
