Estimated water use in South Dakota, 1985

Open-File Report 88-313
Prepared by U.S. Geological Survey in cooperation with South Dakota Department of Water and Natural Resources



Water use in South Dakota during 1985 is estimated to have been 674 million gal/day. This is a slight decrease from the 1980 estimate of 690 million gal/day. Of the total use, 63% was from surface-water sources and 37% was from groundwater sources. About 75% of the total water use was for agriculture, 16% was for domestic and commercial use, 8% was for industrial and mining use, and 1% was for thermoelectric and geothermal uses. Of the total used, 361 million gal/day were consumed and 313 million gal/day were returned to the surface- and groundwater system. Water use by agriculture, the largest user, was mostly for irrigation. Total use was 516,000 acre-ft (460 million gal/day) for irrigation of 397,000 acres. Non-irrigation use, mainly for livestock, was 47.1 million gal/day. About 12% of the total use was by public-water suppliers. Seventy-five percent of the deliveries by public-water suppliers were for domestic use by 78% of the population. In addition to offstream use, instream use was substantial because of hydroelectric-power generation by the four dams on the Missouri River. During 1985, 60,500 million gal/day were used to generate 6,095 gigawatt-hr of electricity.
