And once it did cool, the concrete would crack, rendering the dam useless. The situation required innovations to expedite the curing process.
What will happen if Lake Mead dries up?
‘The pie keeps shrinking’: Lake Mead’s low level will trigger water cutbacks for Arizona, Nevada. … Those reductions could eventually increase in the next few years if Lake Mead drops further. The estimates show the reservoir near Las Vegas will likely begin 2021 about 10 feet above a level that would trigger larger cuts …
