Animas River near Durango – April Fly Fishing Report: As of early April, the Animas River in Durango, Colorado, is experiencing variable spring conditions, with fluctuating weather patterns influencing river flows and water clarity. Anglers should monitor flow rates and target periods of stable or dropping flows for optimal fishing. Effective nymph patterns during this time include Pheasant Tails, Copper Johns, and RS2s in sizes 16–20. For dry fly action, Blue-Winged Olive (BWO) and midge patterns in sizes 18–22 can be productive during midday hatches. Streamer fishing with patterns like Woolly Buggers and Sculpzillas may also yield positive results, particularly in off-color water. Employing light tippets (5x to 6x) and a stealthy approach is advisable due to the river’s clear water and wary trout. Focusing efforts during the warmest parts of the day, typically late morning to early afternoon, can enhance success rates. Overall, the Animas River near Durango offers rewarding opportunities for anglers this April, especially for those who adapt to the dynamic spring conditions.

THE FISHERY
The Animas River at Durango offers a dynamic mix of wild trout fishing, with diverse water conditions and year-round angling opportunities, making it a prime destination for fly fishers seeking a variety of experiences.
Fish Species
The Animas River at Durango is home to healthy populations of wild brown trout and rainbow trout, with the potential for landing trophy-sized fish. The river is managed as a wild trout fishery, and catch-and-release is encouraged in certain sections.
Unique Fishing Conditions
The river flows vary throughout the year, with higher flows during spring runoff, making summer and fall the prime times for fly fishing. The river features diverse fishing conditions, from fast riffles to deep pools, providing a range of opportunities for different fly fishing techniques.
Access and Regulations
Anglers should be prepared with a variety of nymphs, streamers, and dry flies such as midges, caddis, and blue-winged olives, especially during hatches in the warmer months. Some sections of the Animas are regulated as Gold Medal Waters, which means artificial flies and lures only, and strict catch-and-release regulations are enforced to protect the fishery.
TACTICS
AvidMax encourages anglers to explore their full repertoire on the Animas:
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 Animas brings unique joys and challenges for AvidMax anglers:
Spring
Spring runoff can lead to high flows, but nymphing with stoneflies and baetis patterns in slower water along the banks remains productive. Focus on deeper pools and eddies where trout take refuge from fast currents.
Summer
Summer brings excellent dry fly fishing with hatches of caddis, PMDs, and terrestrials like hoppers. Early mornings and late evenings provide the best dry fly action, especially in riffles and along the edges.
Fall
Fall is prime for targeting brown trout as they prepare to spawn, with streamers and egg patterns working well in deeper pools. Look for aggressive trout near structure and in slower runs as they gear up for spawning.
Winter
Winter fishing can be productive by nymphing with small midges and baetis patterns in slower, deeper water. Fish during the warmest part of the day when trout are more likely to be active.

REMEMBER
The Animas River at Durango is a beautiful freestone river offering year-round fishing opportunities, but conditions can vary significantly with seasonal changes and water releases. Respect the river’s fragile ecosystem by practicing catch-and-release and adhering to local regulations, ensuring this fishery remains productive for future generations.
Water Conditions
Spring runoff can lead to high and murky flows, making wading difficult and fishing more challenging. Be sure to check current water levels before heading out.
Regulations
Certain sections of the Animas River are designated as catch-and-release only. Familiarize yourself with local regulations and ensure you’re following appropriate gear and bait rules.
Safety
The Animas River can have fast currents and slippery rocks, especially during runoff. Use caution when wading, and wear appropriate wading gear to stay safe in swift-moving water.
