River in the People's Republic of China
At the mouth it carries 717 m³/s on average: an Olympic pool every 3.5 seconds. Its basin covers 280,000 km², about the size of EC. 106 million people live in it. Highest water: from August to September; lowest: from January to April. It is heavily dammed: reservoirs can hold 180% of a year's flow.

Hai River, month by month
Highest water: from August to September
Lowest water: from January to April. Best months to visit: from April to June and from September to October.
From about 74 m³/s in the lowest month to 850 m³/s in the highest. An estimate: the monthly flow is modelled from the lowest and highest months of WaterGAP (RiverATLAS, 1971–2000) and the rain and snow along the river (WorldClim). Dams change the real rhythm. The chip is the average air temperature; below it, the month's rain.
