Lake Mead's Decline Threatens 70% Cut to Hoover Dam Hydropower Capacity
By
Erin Schulte
Summary
Lake Mead is projected to drop below 1,035 feet above sea level within the next 12 months, a critical threshold that will trigger a 70% reduction in hydropower generating capacity at Hoover Dam. This drastic cut in cheap, responsive power will have significant consequences for regional power customers and the broader electric grid, as the Colorado River continues to struggle to meet demand amid ongoing drought and water management challenges.

· 3 pulledSome day in the next 12 months—maybe in late August, maybe not until next spring—Lake Mead will drop below the critical threshold of 1,035 feet above sea level.
That is the water-level elevation at which hydropower generating capacity at Hoover Dam, the largest in the Colorado River basin, will be cut by 70 percent.
The drastic and immediate reduction in a cheap source of power that is responsive to hourly changes in electricity demand will have consequences for the region's power customers and the broader electric grid alike.
