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.
