ASCE —
Ninety years after the Hoover Dam opened to great fanfare, and following decades of rapid dam building across the country, more dams in the U.S. are now being removed than built.
In 2024 – which tied 2019 for the most dams (108) removed in a single year – the largest dam removal effort in U.S. history was completed. The Klamath River dam removal project dismantled four aging hydroelectric dams along the 257-mile Klamath River in Oregon and California.
