The nearly 8100 major dams in the United States in 2006. The National Inventory of Dams defines a major dam as being 50 feet (15 m) tall with a storage capacity of at least 5,000 acre-feet (6,200,000 m 3), or of any height with a storage capacity of 25,000 acre-feet (31,000,000 m 3).
This is a list of the tallest dams in the United States. The main list includes all U.S. dams over 300 feet (91 m) tall, and a second list gives the tallest dams in each state.

There are over 80,000 Non-powered dams (NPDs) in the United States that could add 12 GW of nameplate capacity or 45 terawatt hours (TWh) per year. The top 100 NPDs alone could add 8 GW, which could add 15% to hydroelectric generation of the 78 GW that was online in 2012. 81 of the top 100 NPDs are owned by the Army Corps of Engineers , the U.S ...
