River Management
TVA uses its 49 dams to manage lake levels and river flows to balance the competing demands on the reservoir system. Whether it’s heavy rains or drought, TVA’s River Management Team works around the clock, managing the Tennessee River system to provide a variety of benefits, including flood control, navigation, hydroelectric generation, recreation, and water quality and supply.

Lake Levels
Taming the Tennessee River was TVA’s first task, and it got the job done by building a system of dams and reservoirs to control flooding and generate power.
