Summary

Description
English: This image, acquired by one of the Copernicus Sentinel-2 satellites on 14 July 2021, shows the current state of Lake Mead in the United States. Comparing the water level in the latest Sentinel-2 image with an extrapolation from a Landsat-5 image acquired in October 1984 (green line) shows that the level of the lake has significantly dropped in several points, with the coastline retreating by more than one kilometre in 37 years. As of June 2021, the level of Lake Mead has dropped to about a third of its total capacity and is at its lowest point in the lake's history. As a consequence of water levels, cuts in downstream water allocations from the Colorado river are planned for 2022. According to experts, the mega-drought that is affecting the west coast of the United States is driven by climate change and is leading to an irreversible aridification of the territory. Data acquired by the Copernicus Sentinel satellites are used to detect and monitor water bodies globally.
