Flood Risk Management

Many dams are designed to help manage floods or reduce downstream flood damages. These dams often provide flood storage that retains and slowly releases flood water to reduce the peak flow in downstream areas. Dams built with the assistance of the Natural Resources Conservation Service provide an estimated $1.7 billion in annual benefits in reduced flooding and erosion damage, recreation, water supplies, and wildlife habitat. Dams owned and operated by the Tennessee Valley Authority produce electricity and prevent an average of about $280 million in flood damage each year.
