Fly Fishing Colorado. Jackson Streit

       Arkansas River

      The “Ark” is a relatively under-fished river, known for a prolific May to June Caddis hatch. Many other hatches combine to make this a true western “big water” fly fishing experience.

      The mountain section flows 150 miles from the old mining town of Climax through central Colorado to the Pueblo Reservoir. From 12,000-foot elevation at the Continental Divide, it drops to 4,700 feet in the eastern plains. There are hundreds of year-round fly fishing opportunities, especially below Lake Creek and from Salida to Pueblo.

      The recent acquisition of the Hayden Ranch Recreation Area adds another 5.8 miles of public water access to the Arkansas. Located just south of Leadville, Hayden Ranch is quickly becoming a favorite of the knowledgeable angler.

      There are numerous rafters, termed “the rubber hatch” by local anglers, May to August.

      The Brown’s Canyon and Royal Gorge runs are particularly popular.

      Fishing from boats can be quite successful especially when casting streamers at the banks and behind structure. Boaters need knowledge of class III-V water. Contact a qualified guide if you’re new to river rafting.
