Lake Mead

Lake Mead, which is the largest reservoir in the United States, is formed by the Hoover Dam on the Colorado River. It is located in the states of Nevada and Arizona in the southwestern part of the US. It provides water to the states of Arizona, California, and Nevada and also to some parts of Mexico. Nearly 20 million people and a large portion of agricultural land depend on the reservoir for water source.
For the first time, federal officials declared water shortage in Lake Mead amid the historic decade-long mega-drought in the region. The water levels at the Hoover and Glen Canyon Dam reservoirs dropped to the lowest since they were first filled because of 22 years of drought.
