South Platte River Fishing Information
Wildcat Canyon - near Deckers, CO
A tough hike in and out, wildcat canyon has a lot of fishable water that remains fairly untouched throughout the year. Most people don’t fish it because of the name (which is accurate, lots of cougars up here) and because it’s a long hike and there is ample fishing closer. You either pass over eleven mile canyon and dream stream or you pass over cheeseman canyon and deckers, all of which are world-class fisheries. Stuck in the middle it’s likely the canyon holds good fish, but few make the effort. Browns and rainbows live here and they range from 12” to 16” most of the time with a few getting bigger. Plan accordingly before access this rugged section and be in good shape to make the trip for the day. Not a great idea to get stuck in cougar town overnight.
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.
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.
Let me start by saying, no matter what, you can’t have a bad day in the canyon. That said, it is one of the hardest places to fish in the world. Many say it is the most technical fishery in the country and for good reason. It’s a steep canyon so access is tricky. Once you get to the clear water, the fish are spooky and require perfect drag free drifts through the multi and cross currents that the large granite boulder create. Mainly a nymph fishery these fish are indicator and split shot shy and require small flies to have success. Pretty much all the tough aspects of a river are rolled up into one on the Canyon (or as I like to call it, the Chedda). Cheeseman canyon is popular but requires a hike to access keeping the less adventurous out. There are some days in the canyon that are lights out and even if you spend your whole day not cathing a fish, the water is gorgeous and you’ll see more fish than you do in most other rivers. The canyon gives you a birds eye view to the fish and I often spend half the day just watching the trout feed from the big boulders above. Fish range 12-18” in this section and can get much bigger than that if you know where to look.
Deckers Tailwater
On the other side of the wigwam club private water below cheeseman, Deckers section begins and continues to the confluence with the north fork of the south platte. This section has a ton of fish and is only an 60-90 minutes from the front range. The proximity to denver makes this place often pretty crowded, but with some driving, you can find open water. There are miles of fishable water and the fish are plentiful. There are more fish above the bridge in deckers most times, but there are also 3x the amount of crowds. Fishing downstream of the bridge often yields more fish. I’ve seen some real beasts down there too, so don’t overlook these sections. There are a lot of 18”+ fish in the river that are worthy of a picture or two. Practice good catch and release here as the fish get pressured hard. It’s a fun and challenging place to fish for the day.

Hatch Charts
Knowing what flies to use is only have the battle. You have to know when the insects are active on the water and when it's likely the trout are feeding on them. Refer to our hatch charts below to understand when the insect categories and some of the possible hatches on the river.
Midge Hatches
Midges hatch year round, but their importance is from September through winter into April. During the warmer months, the trout often focus on larger insects as they are more active on the water like mayflies, caddis and stoneflies.
Aside from Blue wing olives, mayflies are active most commonly from May to August in Colorado. There are many different mayfly hatches found on most rivers and the most common are listed below.
Blue Wing Olive: September throut winter to April
Colors: Green/Olive
Sizes: #16-24
Pale Morning Dun: June to Mid September
Colors: White, Yellow
Sizes: #14 - #20
Green Drakes: June to August
Colors: Olive/Green
Sizes: #8 - #14
Caddis Hatches
Caddis hatch starting early in May and continue to the end of October.
Colors: Olive, Green, Yellow, Tan, Orange, Brown and Black.
Sizes: #10 - #20
Stonefly Hatches
We have some great stonefly hatches in Colorado and while not all rivers carry all species of salmonflies, you can often fish stonefly adult patterns with confidence from May to September. Start off in bigger sizes and get smaller till September hits (size 8 - 16)
Golden Stone: June to August
Colors: Yellow, Tan
Sizes: #8 - #14
Yellow Sally Stonefly: Mid June to August
Colors: Yellow, Tan
Sizes: #12 - #18
Terrestrial Activity
Terrestrials don't hatch since they are out of the water, but they can have importance starting in Mid April and ending in September.

View our access map for the South Platte River and learn public and private access points as well as other notable features around fly fishing this river. We include headwater and confluence data and in an effort to not "hotspot" river access points that are better than others, we list every access point available. This serves two purposes. First, it keeps us from hotspotting, which is just showing the best spots and bringing unwanted and harmful attention to the specific access point. The second reason is while we want to help you catch fish and find great places to explore, we don't want to spell it all out for you. If you get it all spelled out, we're doing the exploring, not you. Missing out on the journey of exploring places to fly fish is one of the more enjoyable aspects of fly fishing. While not everyone has time to go explore everything in person, we provide some of the top level data to help you know if something is worth your time, then pass it off to you to explore and find your own adventure. Now enjoy the info, if you're on this page then this river is worth exploring! Go out and find some memories.
