0002:'0 . CHAPTER V WATER RESOURCES Chapter III. The water supply is designated as adequate on lands having a good early-season supply and a fair sillIlll1er supply for the crops being grown . About 98 percent of the irrigated area is devoted to crops that sup- port the livestock industry, such as alfalfa, pasture, and small grains. The remaining 2 percent is used for garden crops and fruits, mostly for local use. Most of the irrigation is by the land corrugation method, which is well adapted to the topography and crops grown. Sprinkler irrigation is used on about 8 percent of the irrigated land, mostly on systems that re- quire pumping from wells or streams. Sprinkler systems operate in West Paradox, Castle, and Spanish Valleys and along Montezuma Creek and the San Juan River. Sprinklers provide efficient use of water, particularly in areas of uneven topography and coarse-textured soils. Municipal and industrial use . The principal communities in the area have municipal water systems. The few people living outside of communities pipe water from springs and wells or haul it from nearby sources. Residents of the small community of Eastland, Utah, also haul their water. Moab obtains water from springs and wells. The water is of good quality, requiring only chlorination. Measured water use in millions of gallons was 326 in 1964, 298 in 1965, and 347 in 1966. The municipal sys- tem also supplied unmeasured water to the city cemetery and a 9-hole golf course. The community water supply is adequate for present needs although system improvements are being made. At Monticello a network of intakes of springs and streams on the east side of the Abajo Mountains feeds into a pipeline which conveys the water to the city's storage and treatment facilities, including reservoirs with a combined capacity of 65 acre-feet. The city is studying means of in- creasing its storage capacity to better meet peak use requirements. Water use in millions of gallons was 195 in 1964, 273 in 1965, and 275 in 1966. Water for Blanding is diverted near the head of Indian and Johnson Creeks and conveyed by a 15-mile pipeline to city storage and treatment units. The city's three reservoirs have a total capacity of 900 acre- feet. Water use in millions of gallons was 178 in 1964, 157 in 1965, and 180 in 1966. The Blanding municipal water system is adequate for present uses and anticipated near-future growth. . Mexican Hat obtains its municipal water from the San Juan River. Bluff, Aneth, and Montezuma Creek obtain water from wells near the San Juan River. 55
