The Uncompahgre Valley project (Pl. XXII) includes mesa and valley land on the western slope of the Rocky Mountains at an elevation of 5,000 to 6,000 feet above sea level. About 60,000 acres are fruit lands and 80,000 acres general farming lands. The fruit lands when properly irrigated and cultivated are very valuable, and when planted with apples and peaches some of them net as much as $500 per acre per annum. The valley lands, when properly handled and with an adequate supply of water, are also valuable for raising sugar beets and other root crops, as well as many kinds of grasses and cereals. About 20,000 acres have been very inadequately irrigated with the waters of Uncompahgre River. Six miles away, and about parallel with the Uncompahgre Valley, is Gunnison River, which drains a large area reaching to the summit of the Rocky Mountains.

As Uncompahgre River does not carry sufficient water to irrigate the crops in the valley, the water of Gunnison River will be brought to the Uncompahgre Valley, through the intervening mountain range,
