How long will a dam last without maintenance?
Many dams built during the 1930-70s, an era of intensive dam construction, have an expected life of 50-100 years. Due to inadequate maintenance and/or for environmental reasons, some of these dams will fail or be removed in the next 50 years.

How long are dams like Hoover Dam engineered to last?
It’s the little ones you should worry about. Most of the small and medium-sized dams in this country were built to last just 50 years. (Nowadays, from what structural engineers tell me, the typical design life is more like 100 years.)
How old are the dams in the United States?
According to the U.S. Army Corps of Engineers, about 30 percent of the more than 76,000 dams in the United States are older than 50 years — and by 2020, that number will increase to more than 80 percent.
