An Integrated Approach

TVA operates the Tennessee River system to provide a wide range of public benefits: year-round navigation, flood damage reduction, affordable electricity, improved water quality and water supply, recreation, and economic growth.

Most reservoir projects in the United States were built for a single purpose, such as irrigation, power production, or water supply. The Tennessee River system is different. Its dams, locks, and reservoirs were designed specifically to operate as one system that meets many needs.

Every day, TVA balances these competing – and sometimes conflicting – needs for water in order to deliver the greatest value for the 8.5 million people of the Tennessee Valley.

The Board has approved changes in TVA’s reservoir operating policy as a result of extensive analysis including input gathered from the public and other agencies. Read about how these changes will affect river and reservoir operations.


Recreation Release Schedules

Go fishing or experience the excitement of canoeing, kayaking, or rafting on the many stretches of river below TVA dams.


2003 River System Performance (PDF file, 656 kb)

Thanks to the Tennessee River system, we can enjoy boating and fishing, the presence of good jobs in our region, and a greatly reduced risk of flood damage to homes and businesses. Read this annual report to find out about these and other benefits provided through TVA’s integrated operation of the river system.


Shoreline Stabilization

Lakeside property owners can help reduce shoreline erosion through well-designed landscaping plans. Read fact sheets on shoreline stabilization and access the Native Plant Selector, an extensive database that includes information and color photos of plants suitable for specific locations such as the water’s edge.


Hazardous Waters

Strong currents around dams, locks, and powerhouses can pose a great danger to fishermen, boaters, and others who venture too close. Learn about the potential dangers surrounding these TVA facilities, and read about important safety measures you can take.
