The U.S. Army Corps of Engineers (USACE) operates and maintains approximately 700 dams nationwide and in Puerto Rico that provide significant, multiple benefits to the nation—its people, businesses, critical infrastructure and the environment.  These benefits include flood risk management, navigation, water supply, hydropower, environmental stewardship, fish and wildlife conservation and recreation. 

USACE’s dams are part of our nation’s landscape, integral to many communities and critical to watershed management.  Our dam safety professionals carry out a dam safety program to make sure these projects deliver their intended benefits while reducing risks to people, property and the environment through continuous assessment, communication and management. (By comparison there are more than 87,000 dams in the National Inventory of Dams (NID) that are federally, state, locally and privately operated and maintained.)
