Nasa imagees of Lake MeadStark images of the “bathtub ring” around Lake Mead have come to symbolize the devastating effects of drought at America’s largest reservoir. Now, newly released satellite pictures from Nasa offer a new view of how dramatically water levels have declined over the past 22 years.

The images, which cover the years 2000, 2021 and 2022, show once-full tributaries transformed into dry crevasses. The lake, which supplies water to roughly 25 million people across the American west, is currently at its lowest levels since it was filled in 1937. As of 18 July, it stands at just 27% of its capacity.

Michael Carlowicz, managing editor of the Nasa Earth Observatory, described it as “a stark illustration of climate change and a long-term drought that may be the worst in the US west in 12 centuries” in a post on the agency’s site.
