context_page_description: Onalaska is a city in La Crosse County, Wisconsin, United States. The population was 17,736 at the 2010 census. It borders the larger La Crosse, Wisconsin, and is a part of the La Crosse-Onalaska, WI-MN Metropolitan Area.
  Onalaska is built on a slightly elevated ridge above the Black River. Natural areas include both river bottom land and high, heavily wooded, scenic bluffs. A man-made reservoir at the city's western edge is known as Lake Onalaska. Onalaska is known as "The Sunfish Capital of the World."
context_section_description: According to the United States Census Bureau, the city has a total area of 10.73 square miles (27.79 km²), of which 10.13 square miles (26.24 km²) is land and 0.60 square miles (1.55 km²) is water.
  Onalaska lies immediately north of La Crosse, on the Black River. It is the second largest city in La Crosse County.
  Named streams within the current corporate limits of the city include the Black River, the La Crosse River and Sand Lake Coulee Creek. In the 1930s, the construction of Lake Onalaska resulted in the flooding and eventual disappearance of a shallow, natural body of water, Rice Lake, and several smaller ponds in the Black River bottoms area.
  Brice Prairie is an urban reserve area within the City of Onalaska, located below the ridge on which most of the city is situated. It lies to the northwest of the city's current northern border, and is directly on Lake Onalaska.
