Flat Lake is a shallow, natural lake located in Campbell County, South Dakota. It is part of the Prairie Coteau region and is characterized by its relatively flat topography and surrounding agricultural lands.

Flat Lake is primarily fed by surface runoff and precipitation. Its water level can fluctuate significantly depending on rainfall patterns, leading to periods of high water and drought. The lake drains into the Missouri River watershed.

The area surrounding Flat Lake is primarily used for agriculture, including crop production and livestock grazing. The lake and its immediate surroundings provide habitat for various species of waterfowl, shorebirds, and other wildlife. Common bird species observed in the area include ducks, geese, and various migratory birds. The lake also supports populations of fish, although its shallow depth and fluctuating water levels can impact fish populations.

Recreational activities on and around Flat Lake are generally limited due to its shallow depth and fluctuating water levels. Hunting and birdwatching are popular activities in the surrounding area.
