context_page_description: Des Moines County is a county located in the U.S. state of Iowa. As of the 2010 census, the population was 40,325. The county seat is Burlington. It is one of Iowa's two original counties along with Dubuque County; both were organized by the Michigan Territorial legislature in 1834.
  Des Moines County is part of the Burlington, IA–IL Micropolitan Statistical Area.
  Des Moines County should not be confused with the city of Des Moines, which is the capital of Iowa. Des Moines County sits on Iowa's eastern border alongside the Mississippi River. The city of Des Moines is in Polk County in central Iowa. Both places derive their name from the Des Moines River, which flows through the city of Des Moines and originally flowed through the county. When the county was divided early in Iowa's history, the river ended up further west, forming the border between Lee County, Iowa and the state of Missouri.
context_section_description: According to the U.S. Census Bureau, the county has a total area of 430 square miles (1,100 km²), of which 416 square miles (1,080 km²) is land and 14 square miles (36 km²) (3.2%) is water. The Mississippi River forms the east border; Skunk River, the south border; and the county is drained by Flint Creek.
