Colorado Fly Fishing Report for Deckers on the South Platte by Pat Dorsey
The mileage below Cheesman Canyon is the renowned Deckers area, a world-class fishery with easy access and lots of opportunity. The best fishing is from Bridge Crossing to the lower boundary of the Tee Pee Club. Like Cheesman Canyon, the fish are challenging to catch, and there is no substitution for a good dead drift. Deckers can offer good dry fly fishing at times but like upstream in the “The Canyon” a good nympher will catch the majority of fish. Anglers can expect to catch assortment of browns and rainbows with some exceeding 20 inches. The river is made up of riffles, runs, shelves and gravel bars, and nice pocket water. The ideal flow for Deckers is between 150 and 400 cfs. The regulations are two trout over 16 inches in length and flies and lures only. Please consider catch and release on all fish caught in the area.
Deckers is a world-renowned stretch of the South Platte River. There are miles of public water to fish in and around the hamlet of Deckers.
Tips & Other Information:
Outflows are about 75 cfs and the feeder creeks are adding an additional 20 cfs. Denver Water tells me Cheesman Reservoir will NOT spill this year and they are gonna have a tough time fiilling it. Fishing has been good in the Deckers area as of late for 10- 14 inch trout. Fish over 14 inches are fewer in numbers. This is my personal finding and is supported by the latest electro-shocking data. Colorado Parks and Wildlife recently stocked 10 inch catchables in the immediate Deckers area. Plan for a good midge hatch in the morning, followed by a mid-day lull, then some sporacic blue-winged olives in the afternoon. Overcast days are producing the best hatches. Size 22-24 Mercury Midges, Black Beauties, and Top Secret Midges have been the flies of choice lately for the midge-bite. Top Secret Baetis, and Chocolate Foam Wing Emergers are a good choice when you start to see some Baetis moving. When the BWO hatch becomes evident, it’s hard to go wrong with a Sparkle Dun, Para BWO, Hi-Vis Baetis, Mole Fly, Blue Quill, Blue Dun, or Para Adams in sizes 18-20. Caddis are starting to become a factor so make sure you are carrying a few larvae and pupae. Revised 5/29/25
