Recent Reports
Yampa River Below Stagecoach Reservoir – April 2025 Fly Fishing Report: As of early April, the Yampa River below Stagecoach Reservoir is fishing exceptionally well with cold, clear flows around 43 CFS and water temps near 38°F. This tailwater section offers consistent conditions ideal for sight fishing and active trout feeding. Anglers are encountering productive midge and Blue-Winged Olive (BWO) hatches during late morning to early afternoon, making nymphing with Barr’s Emergers, Pheasant Tails, and soft hackles highly effective. BWO dries and midges are also working well during hatch windows, and streamers like Bunny Leeches and Mini Dungeons are producing in deeper slots. A stealthy approach and light tippet (5x–6x) are key to success, and with reliable access just below the dam, this stretch presents one of the top spring fly fishing opportunities in the state..

THE FISHERY
The Yampa River below Stagecoach Reservoir is a renowned tailwater fishery offering year-round fly fishing opportunities, particularly prized for its clear, cold waters and thriving trout population.
Fish Species
The Yampa River below Stagecoach Reservoir is home to healthy populations of both rainbow and brown trout, with some fish growing to trophy sizes, making it a prime destination for anglers seeking large, strong fish.
Unique Fishing Conditions
As a regulated tailwater, the river’s cold, consistent flows provide year-round fishing opportunities, with ideal conditions for nymphing, dry flies, and streamer fishing, particularly during hatches of midges, BWOs, and caddis flies.
Access and Regulations
The river is easily accessible via Stagecoach State Park, but strict regulations, including artificial flies and lures only, along with catch-and-release rules for certain sections, help preserve the fishery’s quality and sustainability.
TACTICS
AvidMax encourages anglers to explore their full repertoire on the Yampa River:
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 on the Yampa River brings unique joys and challenges for AvidMax anglers:
Spring
As snowmelt increases flows, trout tend to hold in deeper pools and slower runs, making nymphing with weighted stonefly or midge patterns especially effective. Keep an eye out for Blue-Winged Olive (BWO) hatches on cloudy days, offering opportunities for dry fly action.
Summer
During summer, lower flows and clear water create prime conditions for dry fly fishing with caddis, PMDs, and terrestrials, especially in the mornings and evenings. Midday fishing can slow down, so focusing on shaded areas and using smaller tippet sizes can increase success.
Fall
Fall brings cooling temperatures and aggressive brown trout preparing to spawn, making streamer fishing highly productive. Midges and BWOs remain a staple for nymphing, with afternoon hatches offering chances for dry fly anglers.
Winter
With reduced flows and frigid conditions, trout become more lethargic and congregate in deeper, slower-moving water. Fishing small midge patterns and focusing on midday hours when the water is warmest can lead to success during the coldest months.
REMEMBER
When heading to the Yampa River below Stagecoach Reservoir, it’s important to remember that this is a cherished and regulated fishery, so preserving its quality is essential for both anglers and the environment.
Water Conditions
Since the Yampa is a tailwater, flows can change quickly due to dam releases, so it’s crucial to check water levels and conditions before you fish to ensure a safe and productive day on the water.
Regulations
This stretch of the river is catch-and-release only, and anglers must use artificial flies and lures—barbless hooks are recommended to minimize harm to the fish population.
Safety
In colder months, icy banks and frigid water can pose safety hazards; wear proper gear like traction devices and waders to stay warm and safe while navigating slippery terrain.
