This pair of satellite images were taken by NASA's EO-1 respectively on May 31, 2018 and June 19, 2019 to compare the conditions of reservoirs in Chennai, the sixth largest city of India. Basically, critical drought attached most parts of India, about 2/3 of reservoirs are getting drier due to the less amount of precipitation, heatwaves, and water management. The Red Hill Lake (central above) is becoming smaller and shallower than one year ago, the same phenomenon occurs on most visible reservoirs in the city. From a macro view, this image set indicates how climate change worsen water shortage in tropical countries such as India; on the other side, it also provides reliable data by satellite to help relative departments make possible solutions.
