The Colorado River in Texas offers fly fishing enthusiasts a diverse and rewarding experience. Known for its healthy populations of bass and sunfish, as well as seasonal runs of other species, this river provides a unique setting for both seasoned anglers and those new to the sport. Flowing through varied terrain, from rugged canyons to more open stretches surrounded by towering trees, the Colorado River is an essential stop for fly fishing in Texas.
This river holds a reputation for its vibrant ecosystem and is a haven for fly anglers who enjoy the challenge of chasing a variety of fish. The diverse water conditions—ranging from calm pools to rapid currents—create opportunities for anglers to experiment with different techniques and fly patterns. For those seeking a well-rounded fly fishing experience, the Colorado River delivers both in quantity and quality of fish.
Fly fishing on the Colorado River is productive throughout the year, with some seasons standing out more than others. The peak time for fly fishing here is from late spring through early fall when water temperatures support active feeding behavior in bass and sunfish. During these warmer months, topwater action can be exciting, especially in the mornings and evenings when fish are most active. Watching a bass explode on a popper or a sunfish eagerly attack a small dry fly on the surface is an exhilarating part of summer fishing on the river.
Winter and early spring can still yield great fishing, particularly when targeting deeper pools where fish hold in cooler water. While the surface activity slows, deeper fishing techniques using weighted streamers or nymph rigs can be very effective. These months are ideal for anglers who prefer a quieter, less crowded river with a different set of challenges. Patience and the ability to adapt to colder water temperatures can lead to rewarding catches.
The shoulder seasons of late spring and early fall are perfect for anglers who enjoy seeing a mix of surface and subsurface activity. These times are marked by changing water temperatures that encourage fish to move between different levels of the water column, making it a great opportunity to use versatile fly patterns and techniques.
Preparation is key to a successful fly fishing trip on the Colorado River. Here are some critical points to keep in mind:
A 5-7 weight fly rod is ideal, especially when targeting larger bass. This weight range offers the flexibility needed to cast both large poppers and more subtle nymphs or streamers. For anglers focusing on sunfish, a lighter 3-4 weight rod can add to the fun and challenge. Bring floating line for topwater action and an intermediate line for deeper sections where fish may hold.
While there are several public access points along the river, some of the best fishing can be reached by kayak or canoe. This method allows anglers to explore longer stretches and reach less pressured waters. If you’re new to the area or prefer a seamless experience, consider a guided trip for access to more secluded sections and expert local knowledge.
The Colorado River’s flow can vary significantly, influenced by dam releases and rainfall. Checking river flow rates and weather conditions before your trip is essential to ensure safety and plan effective fishing strategies. High flows can make wading difficult, but they often push fish into accessible areas near the banks. Conversely, low flows may require a more delicate approach with lighter tippets and smaller flies.
Fly fishing on the Colorado River is an adventure that combines the thrill of casting for aggressive bass with the tranquility of drifting through diverse Texas landscapes. Anglers can expect varied conditions, from slow-moving deep pools to swift runs, making versatility key. The river’s changing depth and flow create natural holding spots for fish, making it essential to stay observant and adaptable.
Whether you’re wading or using a kayak, staying adaptable is essential to capitalize on the river’s many fishing opportunities. Watch for shaded spots under overhanging branches and areas with structure like submerged logs and rocks, as these are prime holding spots for bass and sunfish.

Understanding the local hatches can significantly improve your success on the water. Here’s a month-by-month guide to what you can expect from the myriad of local aquatic life in the area, helping you to choose the right fly and approach for the season. Paying attention to weather conditions and how they affect the trout stream can also enhance your fishing experience.
Bass may hold in deeper water. Streamer patterns like woolly buggers and crawfish imitations are effective. This time of year requires a slower retrieve to entice bites from fish in colder water.
As water begins to warm slightly, try using subsurface flies such as clouser minnows and leech patterns. Fishing deeper pools with a sinking line can be particularly effective during this month.
Activity picks up with the warming temperatures. Poppers and small baitfish patterns work well in shallower sections. Fish become more active and may move closer to shore in search of food.
Caddis and mayfly hatches begin. Use caddis patterns in sizes 14-16 and try using foam ants for topwater bites. The increased insect activity draws fish to the surface more frequently.
Prime time for topwater action. Poppers and foam hoppers are effective, as are streamer patterns when fishing deeper pockets. Bass and sunfish both respond well to surface presentations this month.
Continued success with topwater poppers and grasshopper patterns. Add dragonfly imitations to your lineup for days when you see these insects hovering near the water.
Early mornings and evenings yield the best results. Use stimulators and bass-specific streamers during cooler parts of the day. The heat of midday may push fish into shaded areas or deeper water.
Terrestrials are still strong. Grasshoppers, beetles, and foam ants are reliable choices, with subsurface flies like crayfish patterns working in deeper runs. Pay attention to any surface movement that suggests feeding activity.
As temperatures begin to cool, bass become more active throughout the day. Try a hopper-dropper rig for targeting sunfish and bass. The first signs of cooler weather bring a noticeable increase in fish energy levels.
Focus on subsurface flies such as woolly buggers and nymphs in deeper water as fish slow their surface activity. This is a good time to experiment with varied retrieval speeds.
Return to using streamer patterns and deeper nymphs. Small baitfish and crawfish imitations continue to work well. The holiday season offers a peaceful and scenic time to be on the river with fewer crowds.
