Arkansas Upper Basin

UPDATED: 4/26/26

Flows: 40-60 CFS

Guide Tip of the Week:

The upper Arkansas River is beginning to round into Spring form, but there is not a lot of water in there so fish will be concentrated in specific areas. Fish have been found in deep water to deeper medium riffles. We have found recent success with frenchies, zebra midges, golden stones and a variety of Baetis nymphs. The baetis should still be hatching on overcast day, but the caddis are a little ways off. So a parachute Adams or comparadun #18-20 can produce some fish . The Ark brown are feeding right now. It is a wonderful time to fish the river.

The Headwaters of the Arkansas start near Climax Mine along Fremont Pass (Highway 91 South), and then flow along Highway south of Leadville, all the way to Buena Vista. The upper stretches near Leadville offer tighter fishing along cut banks with willowy vegetation. Good dry fly fishing can be found here as a large variety of aquatic insects dwell in the freestone river. The Caddis population is especially high, and is always a good insect to imitate in the Arkansas River. As the Arkansas flows downstream it becomes wider, with fast canyon areas containing large boulders. These lower stretches from Granite to BV are sometimes better fished with a heavy hopper dropper set up, or a nymph rig.
