Last week, a Siberian hydroelectric dam failed when an explosion rocked the site’s turbine room, killing dozens and taking 6,000 megawatts of electricity offline.
While the tragedy’s ultimate causes are unclear, Russian media has been questioning the state of the aging Soviet-made infrastructure. Dams are getting older in the United States, too. The average age of America’s 80,000 dams is 51 years. More than 2,000 dams near population centers are in need of repair, according to statistics released this month by the Association of State Dam Safety Officials.
