Arkansas Upper Basin
Fishing Report
UPDATED: 6/7/25
Flows: 470 CFS @ Hayden
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.

Guide Tip of the Week:
The upper Ark is looking good! The water height looks to have peaked a few days ago. However, future temps will dictate what we see moving forward. As of now, the nymph fishing will be tough. It is definitely the time to focus on streamer fishing. Smaller yellow, olive and dark articulated streamer on a 6 IPS versaleader is the ticket. Focus on seems tight to the bank and slack inside bends. don’t negate shallow water as the fish will look for refuge from the high water there.
