In 1983, the lake got to its highest recorded water level in ~ 1,225 feet.

Since 2000, the water level has dropped 140 feet, Reuters reports. The previous document its short water level to be 1,071.6 feet in 2016. Now, the lake has actually ducked just below that level in ~ 1,071.56 feet. Researchers suppose the water will proceed receding for at least the next two years.

“It’s frightening the it"s happening so quickly,” water policy professional Felicia Marcus, who is at this time a visiting fellow at Stanford University’s Water in the West program, tells the Arizona Republic. “It"s past yellow alert. It"s the red alert,”

because its highest possible water level in 1983, Lake Mead"s water level has actually dropped more than 150 feet. Ethan fearbut / Getty images
