Existing data were used in conjunction with onsite measurements to evaluate the water resources on the Wind River Indian Reservation, Wyoming. The reservation is located mainly in the Wind River drainage basin. Ground water is used for public- supply, domestic, agricultural, and industrial purposes, and potentially for irrigation. Deposits of Quaternary age provide water for domestic and public-supply uses. Median well yields from different types of Quaternary deposits ranged from 6 to 20 gallons per minute. The Wind River Formation of Tertiary age is a major source of water for domestic and public-supply uses; well yields ranged from 0.1 to 350 gallons per minute. For the Tensleep Sandstone and Madison Limestone of Paleozoic age, wells might yield as much as 1,000 gallons per minute. The dissolved-solids concentration of water from the Little Wind River and Popo Agie River flood-plain alluvium near mountains was generally less than 400 mg/L (milligrams per liter), but with increasing distance from mountains, the range was about 600 to about 750 mg/L. Dissolved-solids concentrations of water in the Wind River Formation ranged from 211 to 5,110 mg/L. Streams provide most water used for irrigation. Discharge records from streamflow-gaging stations indicate flow characteristics of streams on the reservation are extremely variable. Average annual runoff was 122 to 1,150 acre-feet per square mile on perennial streams with gaging stations. Near the mountains, most perennial streams had dissolved-solids concentrations less than 200 mg/L, and with increasing distance from the mountains, concentrations were about 400 to 600 mg/L.
