city, southeastern Saskatchewan, Canada. It lies along the Souris River at the latter's junction with Long Creek, just north of the North Dakota (U.S.) border, 125 miles (201 km) southeast of Regina. It was settled in 1892 with the arrival of the Canadian Pacific Railway, and its name is said to be an acronym of George Stephen and William van Horne, railroad developers. Estevan is mainly an agricultural service centre, with abundant supplies of lignite coal, clay, oil, and natural gas that have given the city a twofold orientation-mixed-farming and mineral extraction. The city is a port of entry from the United States, an administrative headquarters for the oil industry, and a manufacturer of coal briquettes, clay, brick, tile, flour, and dairy products. Extensive tree nurseries line the riverbanks. Boundary Dam, just south of the city, impounds Long Creek for irrigation and flood control. Inc. village, 1899; town, 1906; city, 1957. Pop. (2006) 10,084.
