If Lake Mead were to reach dead pool, it would technically still be able to supply drinking water to Las Vegas. But there will not be enough water for agricultural activities.
Lake Powell and Lake Mead are unlikely to refill for another 50 years - and would need SIX consecutive years of deadly atmospheric rivers to replenish.
Mead reaches dead pool at 895 feet. If Lake Powell reaches dead pool, the US Bureau of Reclamation—which declined our interview requests—would be unable to meet its obligation to deliver water downstream to Lake Mead. In which case, 40 million people would be affected.
The lake, which was created by the Hoover Dam, has been decreasing in size since the 1990s. This is due to a number of factors, including drought, population growth, and climate change. The lake delivers water to Las Vegas, Los Angeles, and Phoenix, so the water crisis is a concern for all three of these cities.
The oldest operational dam in the world, the Lake Homs Dam in Syria, was built around 1300. The masonry gravity dam is over one mile long, 23 feet high, and creates Lake Homs, which still supplies water to the people of Homs today.
