Three large reservoirs—Lake J.B. Thomas and the E.V. Spence and O.H. Ivie Reservoirs provide 97 percent of the District’s water. Together, the lakes can store well over 1.2 million acre-feet of water and supply up to 115 million gallons, or the equivalent of 174 Olympic swimming pools, each day. In addition to providing crucial water supplies for the area, these lakes offer a wide range of local recreation such as fishing, boating, skiing, hiking and camping.
