History[]

Founded on April 10, 1862 as Cole County, it was renamed Union County on January 7, 1864, when its boundaries were changed to encompass land previously part of neighboring Lincoln County. The county seat was moved from Richland to Elk Point on April 30, 1865.

Geography[]

Union County lies on the southeast corner of South Dakota. Its east boundary line abuts the west boundary line of the State of Iowa (across the Big Sioux River), and its south/southwest boundary line abuts the north boundary line of the State of Nebraska (across the Missouri River). The Brule Creek flows southeasterly across the central part of the county, emptying into the Big Sioux. The county terrain consists of rolling hills, devoted to agriculture except around built-up areas.[3] The terrain slopes to the south and east; its highest point is near its northwest corner, at 1,509' (460m) ASL.[4] The county has a total area of 467 square miles (1,210 km2), of which 461 square miles (1,190 km2) is land and 6.6 square miles (17 km2) (1.4%) is water.[5] It is the fifth-smallest county in South Dakota by area.
