Of the tens of thousands of dams in the Corps’ National Inventory of Dams database, the Corps operates and maintains about 700, including six of the 10 largest U.S. reservoirs and half of all federally owned dams. However, like many other infrastructure assets in this country, money is short when it comes to funding repairs and upgrades.
Almost all of the dams the Corps manages are more than 30 years old, and more than half of those have passed the 50-year-old mark, which is when most dams will have exceeded their service lives.
