Rio Grande River near Del Norte – April Fly Fishing Report: As of early April, the Rio Grande River near Del Norte, Colorado, is transitioning into spring conditions. Anglers can anticipate hatches of midges and Blue-Winged Olives (BWOs) during warmer midday periods, providing opportunities for both nymphing and dry fly fishing. Effective nymph patterns include Pheasant Tails, Copper Johns, and RS2s in sizes 16–20. For dry fly enthusiasts, BWOs and midge patterns in sizes 18–22 can be productive during active hatches. Additionally, streamer fishing with patterns like Woolly Buggers and Sculpzillas can yield positive results, especially during overcast conditions. Employing light tippets (5x to 6x) and a stealthy approach is advisable due to the river’s clear water and wary trout.

THE FISHERY
The Rio Grande at Del Norte provides anglers with diverse fishing opportunities, featuring productive riffles and deep runs in a stunning river valley surrounded by the rugged beauty of Colorado’s San Luis Valley.
Fish Species
The Rio Grande River at Del Norte is known for its healthy populations of wild brown trout and rainbow trout, with browns being more dominant. Trout in this section typically range from 12-20 inches, and there are opportunities to catch larger browns, especially in the fall during their pre-spawn activity.
Unique Fishing Conditions
This stretch of the Rio Grande offers a variety of fishing conditions, including deep pools, runs, and riffles, making it ideal for both wade and float fishing. Spring runoff can cause high flows, but late summer and fall provide excellent dry fly fishing with hatches of caddis, blue-winged olives, and stoneflies. Nymphing with midge, mayfly, and caddis patterns (sizes 16-22) is effective year-round. Streamers are particularly productive in the fall for targeting aggressive brown trout.
Access and Regulations
Public access to the Rio Grande at Del Norte is abundant, with several public lands and access points, including boat ramps for float fishing. This section is not designated as Gold Medal Waters, but anglers are encouraged to practice catch-and-release to maintain the quality of the fishery. Water flows can vary with seasonal snowmelt and irrigation demands, so checking current conditions is advisable for optimal fishing.
TACTICS
AvidMax encourages anglers to explore their full repertoire on the Rio Grande:
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 Rio Grande River brings unique joys and challenges for AvidMax anglers:
Spring
Spring runoff brings high flows, but trout can still be caught by nymphing with large stoneflies and streamers in slower water near the banks. Focus on fishing deeper pools and eddies where fish seek refuge.
Summer
Summer offers great dry fly action with caddis, PMDs, and hoppers, particularly in the early morning and late evening when water temperatures are cooler. Target riffles and undercut banks for the best dry fly fishing.
Fall
Fall is prime for targeting aggressive brown trout during their pre-spawn phase, making streamers and egg patterns highly effective. Fish deeper runs and pools where these larger fish hold.
Winter
Winter fishing is slower, but can be productive by focusing on deeper, slow-moving water where trout gather. Nymphing with small midges and baetis patterns during the warmest part of the day is most effective.
REMEMBER
The Rio Grande River at Del Norte offers a diverse and productive fishing experience, with opportunities to target healthy trout in its broad waters. As this is a popular stretch of river, practicing responsible angling is key to maintaining the quality of this exceptional fishery.
Water Conditions
Water levels can fluctuate significantly, especially during spring runoff and irrigation season. Always check current flow rates before heading out, as high flows can impact wading safety and fish activity.
Regulations
Certain sections near Del Norte may have catch-and-release rules and gear restrictions, such as artificial flies and lures only. Familiarize yourself with local regulations to ensure compliance and help sustain the fish population.
Safety
The wide, fast-moving waters of the Rio Grande at Del Norte can be challenging for wading, particularly during higher flows. Wear proper wading boots with good traction, and exercise caution when navigating deeper pools or stronger currents.
