The source of the middle route project of South-to-North Water Transfer Project is

Danjiangkou Reservoir, the source of the Middle Route of South-to-North Water Transfer Project.

The first canal is located in Danyang Village, Xichuan County, Nanyang City, Henan Province. Water dispatching belongs to South-to-North Water Diversion Office of the State Council, and is known as "the first canal in the world". The middle route project of South-to-North Water Transfer Project is about 1432 km long, and the annual average water transfer after the completion of the first phase project is 9.5 billion cubic meters. This is one of the most magnificent water diversion projects in the world.

The original intention of the headwater is to build a water conservancy hub consisting of several buildings in a suitable position in the river course to meet the needs of farmland irrigation, hydropower generation, industrial and domestic water, which is called water intake hub or water diversion hub. Because it is located at the head of the water diversion channel, it is also called the source or source project.
