INDIANA RESERVOIR REPORT

Last Updated: December 5, 2025

Indiana has several major reservoirs and dams used for flood control, water supply, and recreation. Some of the notable reservoirs include the Brookville Lake, Cecil M. Harden Lake, Patoka Lake, and Monroe Lake. These reservoirs rely on streamflow from nearby rivers and creeks such as the White River and its tributaries, the Patoka River, and the Salt Creek. The state's terrain is relatively flat, and there are no significant mountains or snowpack that contribute to the hydrology of the area. Record levels and drought conditions are relatively rare in Indiana, although occasional droughts have affected some regions. The state typically experiences a humid continental climate with warm summers and cold winters, and seasonal trends in precipitation can affect the water levels in reservoirs. Overall, Indiana's reservoirs and dams play a crucial role in managing the state's water resources, providing essential water supply and recreational opportunities while mitigating flood risk.
