The Yangtze is the longest and most economically important river in Asia and the fifth largest in the world in terms of flow. It is also the largest river entirely within a single country. Its estuary had an estimated annual flow of 995.8 km/a (31,550 m/s) between 1955 and 2021.

The last gauging station on the river is at Datong (30°50′57.9192″N 117°43′47.4096″E / 30.849422000°N 117.729836000°E / 30.849422000; 117.729836000). At this location, the water flow is regularly monitored. The chart below is based on average flows between 1950 and 2020.
