Kandiyohi County [2] is a county in the U.S. state of Minnesota. As of the 2020 census, its population is 43,732.[3] As of November 20, 1871, its county seat is Willmar.[4]
Kandiyohi County comprises the US Census Bureau's "Willmar, MN Micropolitan Statistical Area".
Kandiyohi County is named for a Dakota word meaning "where the buffalo fish come".[5] (kandi’ - the buffalo fish + oh-hi’-yu - v. of hiyu - to come through).[6] It was organized on March 20, 1858, with Kandiyohi established as the county seat in 1870 (it was then called Kandiyohi Station, as it was merely a stop on the railroad line). The original county occupied only the southern half of its current area. Development was slow, and in 1870 the state legislature called for Monongalia County to merge with Kandiyohi. It took until November 21, 1871, to agree on the centrally located Willmar as the county seat.
The terrain of Kandiyohi County consists of rolling hills, partly wooded, mostly devoted to agriculture.[7] The territory slopes to the south and west, with the highest point near its northeastern corner, at 1306feet ASL.[8] The county has a total area of, of which are land and (7.6%) are covered by water.[9] Kandiyohi County is one of seven southern Minnesota counties that have no forest soils; only prairie ecosystems of savannas and prairies exist.
