Tens of thousands of islets dot the emerald waters of Danjiangkou Reservoir, creating a fairy tale scene in Danjiangkou City, Hubei Province. As one of the largest reservoirs in Asia, it serves as a regional freshwater supply and is also used for irrigation, electricity generation, and flood control.
It forms part of the South-to-North Water Diversion Project that stretches from the Danjiangkou Reservoir on the Hanjiang River, a tributary of the Yangtze River, to Tuancheng Lake at the Summer Palace in Beijing.
The project aims to provide water to 20 major cities and over 200 counties and districts, benefiting over 80 million residents along the route.
