Colorado River Below Glenwood Springs – April Fly Fishing Report: As of early April, the Colorado River below Glenwood Springs is experiencing elevated flows (around 3,270 CFS) and variable clarity due to warming temperatures and early snowmelt. While runoff conditions can be challenging, anglers willing to adapt are still finding success. Productive strategies include nymphing with large attractors like stoneflies, eggs, and worms, as well as throwing streamers in white, yellow, purple, or black to move bigger fish in off-color water. Midday hours offer the best action as water temps rise, with blue-winged olives, caddis, and stoneflies starting to show up. Staying flexible and monitoring conditions closely is key to unlocking this powerful section of river during spring transitions.

THE FISHERY
The Colorado River at Glenwood Springs is a renowned fishing destination, offering anglers ample opportunities to target large trout amidst the backdrop of towering canyon walls and famous hot springs.
Fish Species
The Colorado River at Glenwood Springs is known for its healthy populations of brown trout and rainbow trout, with browns being more dominant. Trout here typically range from 12-20 inches, with the chance of landing larger fish, especially in the fall when browns are in their pre-spawn phase. This section is also known for its seasonal runs of mountain whitefish, adding diversity to the angling experience.
Unique Fishing Conditions
This section of the Colorado River offers diverse water conditions, including deep pools, riffles, and seams, ideal for various fly fishing techniques. Spring and early summer runoff can create high flows, but late summer and fall are prime times for dry fly fishing with caddis, blue-winged olives, and stoneflies. Nymphing is highly effective year-round with small midge, stonefly, and mayfly patterns (sizes 16-22). Streamer fishing is particularly productive in the fall when targeting larger, aggressive browns.
Access and Regulations
Glenwood Springs provides excellent access to the river, with public fishing areas, boat ramps, and numerous trails along the riverbanks. The river here is part of Colorado’s Gold Medal Waters, meaning it is managed for trophy trout, with regulations encouraging catch-and-release for rainbows and the use of artificial flies and lures only. Anglers should practice responsible fishing to maintain the health of this popular and highly productive fishery. Checking water levels before heading out is recommended, as flows from upstream reservoirs can impact fishing conditions.
TACTICS
AvidMax encourages anglers to explore their full repertoire on the Colorado 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 Colorado River brings unique joys and challenges for AvidMax anglers:
Spring
Spring runoff can cause high flows, but nymphing with stoneflies and baetis patterns in slower water and along the edges is effective. Focus on deeper pools and seams where trout find refuge from fast currents.
Summer
Summer offers great dry fly fishing with hatches of caddis, PMDs, and green drakes. Early mornings and late evenings are ideal for surface action, especially in riffles and along the banks.
Fall
Fall is prime for targeting large brown trout during their pre-spawn period, with streamers and egg patterns working well in deeper pools. Look for trout near structure as they become more aggressive.
Winter
Winter fishing is productive in the deeper, slower runs where trout hold in colder water. Nymphing with small midges and baetis patterns is most effective during the warmest part of the day.
REMEMBER
The Colorado River at Glenwood Springs is a renowned fishery, offering incredible trout fishing opportunities alongside one of Colorado’s most scenic towns. However, with its popularity comes the need for careful stewardship—practicing catch-and-release and following regulations are essential to preserve this river for future generations.
Water Conditions
Flow rates can vary significantly depending on dam releases and runoff, especially in spring. Always check water levels before heading out to ensure safe wading and optimal fishing conditions.
Regulations
Certain stretches of the river near Glenwood Springs may have specific regulations, including catch-and-release or artificial flies and lures only. Be sure to review local regulations to help protect the fishery.
E
Safety
The river’s swift currents and rocky bottom can make wading tricky, especially during higher flows. Wear proper wading gear, exercise caution in faster water, and be aware of the river’s popularity with boaters and rafters, particularly in summer.
