Water comes in from the Colorado River. The last I knew, there was actually too much water coming in. The excess was sent into the natural underground reservoir under Phoenix. Probably planning to tap into that water.
“The Central Arizona Project aqueduct system is shown west out of the Phoenix metro area. The aqueduct meanders more than 300 miles to divert Colorado River water to Phoenix and Tucson.”
“As soon as 2019, the water level in Lake Mead on the Colorado River could drop below an elevation of 1,075 feet. That will trigger mandatory cutbacks in water diversions from the reservoir under an agreement negotiated between the federal government and three lower-basin states that rely on the river: Arizona, California and Nevada.”
Also, if California just put in a few desalination plants, then there would be plenty of fresh water without the Colorado river water and the cycle of water shortages would end.
Their canal goes right by the area north of Tonapah.
