About Onalaska

Onalaska is a La Crosse County city built on a slightly elevated ridge above the Black River. It sits beside Lake Onalaska, a man-made reservoir at the city's western edge, giving the community a strong river-and-lake setting. The original village was platted by Thomas G. Rowe, and modern Onalaska functions as both a residential suburb of La Crosse and a regional destination, with the Onalaska Omni Center serving as its convention center and indoor arena.
