UNCOMPAHGRE VALLEY

The 'Uncompahgre Valley' is an agricultural valley of the Uncompahgre River around the town of Montrose in the western part of the U.S. state of Colorado. The valley is bounded to the south and east by the San Juan Mountains and to the west by the Uncompahgre Plateau.
Agriculture in the Uncompahgre Valley was made possible by the construction of the Gunnison Tunnel which diverted irrigation water from the Gunnison River in the Black Canyon of the Gunnison to augment irrigation waters from the Uncompahgre River which could run low in summer after the spring snowmelt.
