Low water levels on the Colorado River could force water shortages in Arizona, Nevada and Mexico in 2020, according to a new forecast from the U.S. Bureau of Reclamation.
A shortage on the river is tied to the level of its main reservoir, Lake Mead near Las Vegas, Nevada. If the lake drops past an elevation of 1,075 feet, water users downstream have to start cutting back how much water they use. The U.S. Bureau of Reclamation projects the lake to drop below that level next year, triggering water cutbacks in 2020.
Westerners in many states are using less water. However that’s not the case in the Mountain West. In Colorado, Wyoming, Utah and Idaho, home usage went up; in Montana it stayed the same. Experts say these figures are based less on population growth and more on state water policies.
Between growing populations and changing climate conditions, our water sources are only expected to get more crunched. Communities in some very dry states have had to get creative about where to get their water, sometimes purifying sewage into drinking water. More western cities are beginning to get on board, too. But there’s a problem: the ick factor.
