Las Vegas & Lake Mead 1972-2021 Satellite Timelapse NASA Imagery #lasvegas #lakemead #water #drought

Las Vegas & Lake Mead - 1972 to 2021

These newly released time lapse images were created using reflected light from the near-infrared, red and green portions of the electromagnetic spectrum. The large red areas tracked by this imagery are "green spaces" that indicate vegetation or irrigation; usually golf courses, city parks, washes and other water sources.

It should be noted that even though the population of Las Vegas has doubled in recent decades, their overall water use has DECREASED due to conservation and reclamation efforts shared by the community.

Satellite images were obtained from USGS Earth Explorer Landsat Program courtesy of NASA/Goddard Space Flight Center.
