A year ago, California’s Oroville Dam almost failed. The nation’s tallest dam — says the Federal Energy Regulatory Commission (FERC) — had some serious structural failures. It is hard to imagine how weaknesses built into the dam were overlooked for decades.
The commission oversees the nation’s 90,580 dams and says there are another 1,700 hydroelectric dams in other parts of the country that just might have similar flaws since most are now 50-years old or older.
The FERC owners of those dams are expected to take a very hard, and very honest, look at them.
“We are focusing on how to improve our program to identify and prevent incidents, regardless of magnitude, that could result from similar dam safety and organizational factors that contributed to the Oroville incident. We expect our regulated dam owners to have similar internal discussions,” the FERC wrote.
