RIVERTON

city, Fremont county, west-central Wyoming, U.S. It lies along the Bighorn River at the mouth of the Wind River. Founded and incorporated as Wadsworth in 1906, it was renamed Riverton because of its location near the convergence of four rivers. Riverton is a shipping point for the Wind River basin, which is irrigated by the Riverton Power and Land-Reclamation Project. The city has livestock interests, uranium and sulfuric acid plants, and mills producing railroad crossties and fence posts. Oil and natural-gas fields are nearby. The Central Wyoming College opened (1966) in Riverton. The city is adjacent to the Wind River Indian (Shoshone and Arapahoe) Reservation. Pop. (1990) 9,202; (1994 est.) 10,060.
