The name of the Uncompahgre River comes from the Ute word that means red water, muddy water or a water that is slow moving. The Utes lived along the river since early times because of the water, plants and wildlife. Flowing from the headwaters in the San Juan Mountains, the river is the artery of a large watershed and one reason many people choose to live here in Ouray County. Whether enjoying recreation on and around the river and the Ridgway Reservoir or using the valuable natural resource for irrigating agricultural fields, we rely on the watershed to support our lifestyles.
The Uncompahgre River drains 1,115 square miles of the Gunnison Basin in southwestern Colorado. This drainage area includes parts of Delta, Montrose, Ouray, Gunnison, Hinsdale, San Juan and San Miguel Counties in southwest Colorado. The elevation ranges from 14,158 feet at the peak of Mt. Sneffels to 4,915 feet at the mouth in Delta. The Uncompahgre River originates in Lake Como at 12,215 feet in the Uncompahgre National Forest. It flows approximately 75 miles northwest past the City of Ouray, Town of Ridgway, City of Montrose, and Town of Olathe and joins the Gunnison River at Confluence Park in the City of Delta.
