The NID is the central repository for information about dams in the United States and its territories that meet specific criteria.  The congressionally authorized database shows the location of these dams and serves as a resource to support awareness and preparedness for a dam-related emergency.  The website hosting this database just got a “make-over” with new features and is easier to use.

The U.S. Army Corps of Engineers (USACE) is responsible for maintaining the NID and closely collaborates with federal and state dam regulating agencies to obtain accurate and complete information about dams in the database.

The new website has better navigation, and there are important new components such as flood inundation maps.  These maps are very important to users who can now quickly and easily download and share maps showing different flooding scenarios in their area. This enables them to identify people and places at risk during likely flooding events so they can take critical action ahead of time and be more prepared.
