The Uncompahgre River is a waterway in southwestern Colorado, originating high in the San Juan Mountains near Ouray and flowing northward for approximately 75 miles before joining the Gunnison River near Delta. This river system drains a significant portion of the Uncompahgre Valley, passing through the towns of Ouray, Ridgway, Montrose, and Delta along its course. Paddling opportunities on the Uncompahgre vary greatly, offering everything from intense whitewater in the upper reaches to more mellow floats in the lower sections.

The river can be divided into several distinct paddling sections: 1. The Uncompahgre Gorge near Ouray: A challenging Class IV-V+ run with steep gradients and technical rapids, suitable only for expert kayakers. 2. Ouray to KOA Campground: A 4.6-mile stretch of Class III-V+ whitewater, featuring continuous rapids and beautiful mountain scenery. 3. Ridgway to Ridgway Reservoir: A popular 3.2-mile Class II-III+ section, ideal for intermediate paddlers and introductory whitewater experiences. 4. Montrose Town Run: A 2-mile urban paddling experience with Class II-III rapids, featuring the Montrose Water Sports Park. 5. Billy Creek SWA to Trout Road: A longer, more mellow 19-mile stretch popular for fishing and scenic floating.

The overall difficulty of the Uncompahgre ranges from Class I to V+, requiring varying levels of skill depending on the section. Paddlers should carefully assess their abilities and choose appropriate sections. The best paddling season typically runs from late spring through early summer when snowmelt increases water flows. However, some sections, like the Montrose Town Run, can be paddled from late March into October due to sustained irrigation flows.

The river corridor supports a diverse ecosystem, home to brown and rainbow trout, as well as occasional cutthroat trout. Wildlife such as deer, elk, and various bird species can often be spotted along the banks. Key landmarks include the dramatic Uncompahgre Gorge near Ouray, the Ridgway Reservoir, and the Montrose Water Sports Park. The river also passes through scenic ranchlands and offers stunning views of the surrounding San Juan Mountains.

Access points are numerous, with popular put-ins and take-outs in Ouray, Ridgway, and Montrose. Many sections are easily accessible from Highway 550. Historically, the Uncompahgre River played a crucial role in the development of the region, supporting mining and agricultural activities. Today, it continues to be an important water source for irrigation and recreation.

Safety considerations include scouting unfamiliar rapids, being aware of potential wood hazards, and respecting private property along the river. Some access points, like Billy Creek State Wildlife Area, may require a hunting or fishing license for use. While most runs on the Uncompahgre are day trips, multi-day adventures can be planned by combining different sections or incorporating camping at designated areas along the river corridor.
