Lake Mead provides the vast majority of the drinking water for the Greater Las Vegas region and the population there will continue to grow at a high rate for the foreseeable future:

"Accounting for these factors and anticipating future trends, the population of the Las Vegas-Henderson-Paradise metro area in Nevada is projected to grow from 2,335,600 in 2022 to 4,450,000 in 2060. The 90.5% projected population growth in the metro area is the fifth highest of all 384 U.S. metro areas." - https://www.thecentersquare.com/nevada/las-vegas-nv-will-be-among-the-fastest-growing-cities-by-2060/article_daa06351-54fc-5b41-95ae-f8f07eab4fdf.html

The federal government should have a plan of action in place for supplying enough fresh water for the growing population of the Greater Las Vegas region, and also should have a plan of action for supplying enough water for the continued operation of the Hoover Dam, in the event of Lake Mead drying up in the near future. I am curious to know what those two plans are.

What are the U.S. government's plans for dealing with the event of Lake Mead drying up in the near future?
