Fly Fishing Green River - Warren Bridge

Fly fishing the Green River – Warren Bridge Section delivers an accessible, high-desert freestone experience in one of Wyoming’s most iconic trout fisheries. Just north of Daniel, WY, this reach of the upper Green flows through open sagebrush valleys with the Wind River Mountains rising dramatically in the distance. The Warren Bridge Public Access Area provides miles of easily reached water, making it a favorite for both local anglers and traveling fly fishers looking for wild trout in a scenic setting.

This stretch of the Green is a freestone river with a moderate gradient, offering a variety of water types. Anglers will find classic riffle-run-pool sequences, long glides perfect for dry-fly presentations, and cutbanks that fish well with streamers. The cobbled bottom and mix of deep and shallow water create diverse holding lies, and the broad valley setting means the river is wide open to drifting dry flies during summer hatches. While it is not as large or float-oriented as the downstream reaches near Fontenelle, the Warren Bridge section is tailor-made for wade fishing.

The river supports a healthy mix of brown and rainbow trout, with occasional brook trout in cooler tributary-fed areas. Browns are especially common here, with many fish in the 12–16 inch range and opportunities for larger specimens, particularly in fall. Rainbows provide steady action throughout the season, and while this section is not a numbers fishery like some tailwaters, the trout are wild, strong, and rewarding to pursue.

Hatches are reliable and varied. Spring features blue-winged olives and midges, while early summer brings prolific caddis and PMDs. Stoneflies, including golden stones, appear in June and July, and by midsummer terrestrials become a staple, with grasshoppers, ants, and beetles producing some of the best dry-fly action of the year. Fall brings another round of BWO hatches, and streamer fishing heats up as browns become aggressive ahead of the spawn. The river’s freestone flows make hatch timing highly dependent on runoff, with prime fishing typically beginning in late June once flows recede.

Wading is best when flows run between 150 and 600 CFS, allowing anglers to cross safely and target mid-river seams. Above that range, the river becomes swift and challenging to fish effectively. The Warren Bridge Public Access Area provides multiple miles of entry, with parking areas and trails leading directly to the river. Additional access is available downstream near Daniel and through parcels of public land managed by the Bureau of Land Management. With easy roadside access, broad casting lanes, and consistent insect life, this stretch is well-suited for anglers of all experience levels.

For anglers seeking a classic Wyoming freestone experience with easy access, wild trout, and sweeping mountain views, fly fishing the Green River at Warren Bridge is a must. It offers a blend of convenience, beauty, and opportunity that makes it one of the most beloved fisheries in the state.
