Lake Mead in Nevada is suffering from a historic drought along with the rest of the Western United States. Historically, the reservoir has provided more than 90 percent of Las Vegas’ drinking water.

Federal water managers are now projecting that the lake won’t have enough water to fulfill deliveries to Nevada and Arizona in 2018 according to a report released on August 16, 2016.

Here, the water levels are down more than 60 percent of capacity in May 6, 2015. In September 2015, the reservoir was down 147 feet from full capacity in 1983 and only 38 percent full. In 2016, the levels the reservoir is just 36 percent full, at its lowest level Wednesday since the reservoir was created.
