South Platte River Fishing Information
Dream Stream - near Lake George, CO
Some of the biggest fish each year are caught here. Fish over 30” have been landed during the spring and fall as the fish spawn and come out of eleven mile reservoir. Large resident fish stay here as well and are tough but rewarding to catch. There are a lot of fish in this section and though it can get crowded, it’s a rewarding place to fish. Nearly 3 miles of public fishing are available from the tailwater below spinney mountain reservoir to the inlet of eleven mile reservoir. During the fall Kokanee run up the river as well giving you a chance to catch them on the fly. Though there is some good dry fly fishing from time to time, it is sporadic and this section is most commonly a nymph fishery.
The South Platte River
The South Platte is Colorado’s primary river for fly fisherman. There is more river access, tailwaters and fish on this river than you could explore in a year. There is a ton of variety on this river. Whether you want to catch high mountain brook trout in solitude, or hunt large trophy bows on tailwaters you can find it on the platte. You can even chase carp and smallmouth bass in the heart of Denver. Much of the water is protected and catch and release is almost always preferred and regulated. It’s important to preserve this river and let fish go so they can grow.
The river begins up in South Park and the Middle Fork and South Fork run through the South Park area. This river is a meandering meadow stream until it gets into the first canyon below Eleven Mile Reservoir. Granite rocks make for some scenic views and excellent runs, holes and riffles to find eager trout. The river continues the granite formations until it enters Denver from Chatfield Reservoir. As it enters several reservoirs downstream, it provides excellent tailwater fishing for some of the largest trout in the state. After moving through several of the best places to fish in Colorado, it enters into Denver and provides anglers an opportunity to catch carp and small mouth bass on the fly.
You can catch Rainbows, Browns, Cutthroat, Cutbows, Brook Trout, Tiger Trout, Smallmouth Bass, Common Carp and more in this river and the fish are all different sizes. The real difficulty to the south platte is learning each section. The difference in fishing techniques and flies is drastic from section to section. See the list below and use our river explorer app to find the section that is right for you.
Reservoirs of the South Platte
There are 6 reservoirs that dam the south platte. Every reservoir except Antero provides a tailwater section below that is publically accessible See the list below and their related tailwater sections. These make up the majority of the fishable sections on the South Platte.
Eleven Mile Canyon has one of the highest fish per mile counts on the south platte and holds rainbows, browns, cutbows and cutthroat. Fish are gorgeous in this section and you can experience some excellent dry fly fishing during hatches. Fishable year round, you can often sight fish to many of the trout in this section. Some very large fish are caught here every year to the angler who gets lucky or works hard to find them.
