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.
Hydroelectric & non-power
Summer net capability
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.
Kayaking, rafting and trout fishing—all activities that you can do in the tailwaters below TVA dams—are growing in popularity. Find out more about how you can “go with the flow” and get involved with these fun sports.
