"SALT LAKE CITY — A massive reservoir known as a boating mecca dipped below a critical threshold on Tuesday raising new concerns about a source of power that millions of people in the U.S. West rely on for electricity.
Lake Powell’s fall to below 3,525 feet (1,075 meters) puts it at its lowest level since the lake filled after the federal government dammed the Colorado River at Glen Canyon more than a half century ago — a record marking yet another sobering realization of the impacts of climate change and megadrought.
It comes as hotter temperatures and less precipitation leave a smaller amount flowing through the over-tapped Colorado River. Though water scarcity is hardly new in the region, hydropower concerns at Glen Canyon Dam in Arizona reflect that a future western states assumed was years away is approaching — and fast.
“We clearly weren’t sufficiently prepared for the need to move this quickly,” said John Fleck, director of the University of New Mexico’s Water Resources Program."
