South Platte River – Deckers – April 2025 Fly Fishing Report: As of late March 2025, the Deckers section of the South Platte River is exhibiting favorable early spring conditions. Flows are currently at 170 cubic feet per second (CFS), slightly above average for this time of year. These stable flows have encouraged fish to spread out across various habitats, including riffles, runs, shelves, gravel bars, and pocket water. Anglers can anticipate hatches of midges throughout the day, with Blue-Winged Olives (BWOs) beginning to appear, especially during warmer midday periods. Effective nymph patterns include Pheasant Tails, Copper Johns, and RS2s in sizes 16–20. For midges, patterns like Top Secret Midge and Miracle Nymph in sizes 20–22 are productive. Dry fly enthusiasts may find success with Parachute Adams and Matt’s Midge in sizes 22–26 during active hatches. The river’s clear water necessitates a stealthy approach and precise presentations. Employing light tippets (5x to 6x) is advisable due to the technical nature of the fishery. Focusing efforts during the warmest parts of the day, typically late morning to early afternoon, can enhance success rates. Anglers should also be mindful of spawning activity during this period and avoid disturbing fish on redds to support the health of the fishery. Overall, the Deckers section of the South Platte River offers rewarding opportunities for anglers this April, particularly for those who adapt to the technical challenges presented by early spring conditions.

THE FISHERY
Deckers is a dream destination for AvidMax anglers seeking both variety and challenge. This stretch of the South Platte boasts:
Fish Species
The South Platte River near Deckers is home to healthy populations of brown and rainbow trout, with fish typically ranging from 12-18 inches, though larger trout are possible, especially in the fall during the brown trout spawn. Deckers is known for producing quality wild trout, and its proximity to Denver makes it a popular destination for anglers seeking both quantity and quality.
Unique Fishing Conditions
This section of the South Platte features a variety of water conditions, including riffles, runs, and deep pools. The clear water and high fishing pressure make for technical conditions, requiring stealth, light tippets, and accurate casting. Spring and fall offer the best dry fly opportunities with blue-winged olives, caddis, and midges. Nymphing with small midge, baetis, and caddis patterns (sizes 18-22) is effective throughout the year, especially in deeper runs. Streamers can also work well in the fall, targeting larger, aggressive trout.
Access and Regulations
Access to the South Platte near Deckers is excellent, with numerous public access points and parking areas along Deckers Road (County Road 126). This stretch of the river is part of Colorado’s Gold Medal Waters, meaning it is managed for trophy trout, with artificial flies and lures only. Catch-and-release is encouraged to maintain the wild trout population. Water flows can fluctuate due to releases from Cheesman Reservoir, so checking flow conditions before fishing is advisable for optimal wading and fishing conditions.
TACTICS
AvidMax encourages anglers to explore their full repertoire at Deckers:
Nymphing
Nymphing allows anglers to target trout feeding below the surface, with or without an indicator, making it an effective technique for covering deep runs and slow pools where fish are actively feeding on subsurface insects.
Dry Fly Fishing
Fishing with dry flies provides the ultimate surface experience, imitating adult insects and offering exciting visual strikes, particularly during hatches when trout are feeding on the water’s surface.
Streamer Fishing
Using streamers mimics baitfish and other larger prey, offering an aggressive approach that can entice bigger, predatory trout, especially when fishing deeper water or fast-moving currents.
SEASONS
Each season at Deckers brings unique joys and challenges for AvidMax anglers:
Spring
Spring runoff can lead to higher flows, but trout remain active in slower water near the banks. Nymphing with stoneflies, baetis, and San Juan worms is highly effective during this period.
Summer
Summer provides excellent dry fly fishing with hatches of caddis, PMDs, and terrestrials. Focus on fishing early in the morning or late in the evening when water temperatures are cooler and trout are more active.
Fall
Fall is prime time for targeting aggressive brown trout during their pre-spawn, with streamers and egg patterns being especially effective. Concentrate on deeper runs and pools where trout hold during this period.
Winter
Winter fishing at Deckers is best during the warmest part of the day, with trout seeking slower, deeper water. Small midge and baetis nymphs fished under an indicator are the most effective approach in cold conditions.
REMEMBER
The South Platte River at Deckers is a popular destination for trout fishing, offering accessible waters and healthy fish populations. However, the high fishing pressure and tailwater conditions require responsible angling practices to maintain this productive fishery.
Water Conditions
The flow in Deckers is controlled by releases from Cheesman Reservoir, so water levels can fluctuate quickly. Always check flow rates before heading out, as high flows can make wading difficult and change fish feeding behavior.
Regulations
Much of the Deckers stretch is catch-and-release only, with artificial flies and lures required. Familiarize yourself with these rules to help protect the fishery and ensure a sustainable trout population.
Safety
While Deckers offers relatively easy access, the riverbed is rocky, and the currents can be strong during higher flows. Wear proper wading boots with good traction, and exercise caution when navigating deeper pools and faster-moving water, especially near the bridges and popular access points.

I like it. A Lot! As a guy who shops at your store front (and CFB) all the time, and who checks everyone’s fishing reports to tie what I need before the weekend, it’s great to see you fill this niche (& gap). Trout’s was on it until they went under, and you are the logical business to carry the baton now. Anglers All does it but their browsing layout is just weird and missing details I need. Angler’s Covey’s version is fine, but they’re further down the range and I have to believe that if they’re driving 30 min. further than I am, which is a lot, that the info won’t be as current or as nuanced or updated as frequently.
There are some subtle web layout topics I’d consider, like alphabetizing based on common names (Deckers / Dream Stream / THE canyon) vs. the watershed then the N/S fork, etc. I can adapt to your approach navigating it all, and maybe that’s more technically correct, too. Not everyone uses the nicknames. We’ll see. And mobile reporting…well, that’s what everyone wants but you need a more enterprise grade tool like Microsoft Power BI to make that easier to support. I get it for free for 15K users, so that’s probably not realistic. Most mobile information comes from dedicated platforms with subscription fees.
Thanks for taking the time to build this all. I do this type of stuff for a living (Business Intelligence, online analytics, dash boarding, data management, etc.) and I know it is both a PITA and a labor of love. Keep at it. I sincerely hope you are in it for the long run! It takes a small army to gather the intel, too.
