The water source for Community Water System is Greers Ferry Lake, a White River Basin project built by the U.S. Army Corps of Engineers and completed in July of 1964. The dam is located on the Little Red River just northeast of Heber Springs, Arkansas. The purpose of the lake is flood control and the generation of hydroelectric power, but it also provides exceptional recreational opportunities as well as an excellent source for water. To give you some idea of it's size, Greer's Ferry Lake has 40,500 surface acres when the pool level is at it's highest point, and 31,500 surface acres during low or conservation levels. There are from 276 to 343 miles of shoreline depending on lake levels.
