Show and La Plata Rivers for irrigation, municipal and industrial use, recreation, and fish and wildlife conservation. Animas River water would be regulated at the Howardsville Reservoir. The stored water would be released to the river and most of it, together with natural inflows to the river, would be diverted 23 miles downstream and conveyed in the Animas Diversion Canal to the La Plata River Basin. The remainder would be diverted from the Animas River for municipal use at Durango, Colorado, and Aztec and Farmington, New Mexico. Part of the Durango water would replace present diversions to the city from the Florida River, permitting the replaced water to add to the supply for the Florida Project. Water delivered to the La Plata River Basin and unused flows of the La Plata River would be regulated in the offstream Hay Gulch, Three Buttes, and Ute Meadow Reservoirs and distributed by private and project works for irrigation and anticipated industrial uses associated with the areas' extensive coal fields. A total of 72,120 acres would be irrigated, of which about 23 percent is in New Mexico and 77 percent in Colorado. The lands include 7,520 acres in Indian ownership. The project would provide 76,000 acre-feet of water annually for municipal and industrial use.

Dallas Creek Project The Dallas Creek Project would develop water of the Uncom-pahgre River and tributaries for irrigation and municipal and industrial use. It also would provide benefits to recreation, fish and wildlife, and flood control. Principal storage would be provided by the 146,500-acre-foot capacity Ridgway Reservoir. It would be formed by a 172-foot high dam on the Uncompahgre River and a 165-foot dam on Dallas Creek. Flows of Cow Creek would be brought to the reservoir by feeder canal.
