Fly Fishing Rio Grande River - Upper

The Upper Rio Grande above Creede is a high-country headwater experience framed by alpine meadows, dense spruce forests, and the dramatic peaks of the San Juan Mountains. Flowing cold and clear from the Rio Grande Reservoir outlet, this freestone section is a dry fly paradise — consistent summer flows, prolific insect hatches, and wild trout eager to rise in water that rarely sees heavy pressure.

In late spring and early summer (June-July), as snowmelt tapers and the river drops into wadeable shape, riffles and pocket water come alive with caddis, blue-winged olives, and stonefly hatches. The salmonfly emergence in mid-June is the headline event, bringing aggressive surface eats from trout tucked behind boulders and undercut banks in the deeper canyon stretches.

Throughout summer, cold water temps keep fish active all day. Dry-dropper rigs with elk hair caddis, Chubby Chernobyls, and attractor dries paired with beadhead pheasant tails or hare’s ears consistently produce. Brook trout and cutthroat dominate the uppermost reaches near Thirtymile Campground and the Weminuche trailheads, while browns and rainbows become more prevalent closer to Creede.

Fall (September-October) transforms the valley into a tapestry of golden aspens, and steady low flows reveal perfect walk-and-wade conditions. Blue-winged olives and midges draw trout into slow seams and tailouts, while streamer fishing becomes increasingly productive along deeper bends.

Public access is abundant along Forest Road 520, especially near Thirtymile Campground, the Rio Grande Reservoir outlet, and pullouts upstream of Creede. This section is ideal for anglers seeking solitude, scenic beauty, and technical small-stream fly fishing in one of Colorado’s most spectacular alpine settings.
