Type 3 claims explains why water levels mead have changed?

Explanation:

1- The lake has remained below full capacity since 1983 due to drought and increased water demand. As of April 2020, Lake Mead held 42.97% of full capacity with 11.3 million acre feet (1.39×1013 L), up from 10.4 million acre feet (1.28×1013 L) in 2019 and the low of 9.8 million acre feet (1.21×1013 L) in 2016.

2- Caption by Michael Carlowicz. In August 2010, Lake Mead reached its lowest level since 1956, the result of a persistent drought and increasing human demand.

3- 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.
