English: The Peñuelas Lake, located 120 kilometres west of Santiago, was one of the main sources of water supply for the Valparaíso region in Chile. Together with the Los Aromos lake, it supplies water to almost two million inhabitants of the Valparaíso region, and supports the local fauna, which is now struggling to survive. In fact, because of the multiannual drought that is affecting Chile, the lake has now almost completely dried up. According to the latest report by the Valparaíso Sanitation Company, the Peñuelas Lake current capacity barely reaches 170 thousand cubic meters, which amount to only 0 .2% of its total capacity of 95 million cubic meters. These images, acquired by the Copernicus Sentinel-2 satellites on 4 April 2016 (left) and 24 March 2022 (right) show the dramatic effects of the drought on the Peñuelas Lake, which now looks almost completely dry.
