Council Grove Lake is a reservoir on the Neosho River in east-central Kansas. Built and managed by the U.S. Army Corps of Engineers, it is used for flood control, recreation, and water supply. The surface area, surface elevation, and water volume of the reservoir fluctuate based on inflow and local climatic conditions. In terms of capacity, the Corps of Engineers vertically divides the reservoir into a set of pools based on volume and water level, and the reservoir is considered full when filled to the capacity of its conservation pool. When full, Council Grove Lake has a surface area of 13.09 km2, a surface elevation of 388 m, and a volume of 54,253,000 m3. When filled to maximum capacity, it has a surface elevation of 394 m and a volume of 161,682,000 m3.
