Geography
The CDP consists of lakefront communities surrounding two lakes, North Twin Lake and South Twin Lake. The lakes, which do not have a discernible surface outlet, are part of the North Raccoon River watershed, a tributary of the Des Moines River. Twin Lakes State Park occupies the surface area of the two lakes plus small portions of the shoreline. U.S. Route 20 runs just south of the southern edge of the CDP, leading east to Fort Dodge and west to Sioux City. Rockwell City, the Calhoun County seat, is to the south.
