Lake Mead drop threatens Hoover Dam turbines; 12 of 17 damaged below 316m

Lake Mead's declining level is causing severe cavitation damage to 12 of Hoover Dam's 17 turbines once the reservoir falls below 316 meters, hampering power generation. The situation is expected to worsen, and turbine renovation will take years, posing a long-term threat to regional electricity supply and water management.
