Lake Powell's drastic drop in water level shown in clear satellite images


Lake Powell, a massive reservoir that millions of people rely on for water and hydropower electricity, dipped to a critical point last month.

The difference is glaring.

The lake's elevation dropped to 1075 m above sea level, its lowest level since the lake filled after the federal government dammed the Colorado River at Glen Canyon more than 50 years ago.

The satellite images show changes of the reservoir near Bullfrog Marina between March 2018 and March 2022. 

The drop comes as hotter temperatures and less precipitation leave a smaller amount flowing through the over-tapped Colorado River.
