Its basin covers 130,000 km², about the size of NI. 14.5 million people live in it. Highest water: from September to October; lowest: from January to April. Dams and reservoirs hold back a large share of its water (21% of a year's flow).

Mun River, month by month
Highest water: from September to October
Lowest water: from January to April. Best months to visit: from November to February.
From about 280 m³/s in the lowest month to 2,400 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.
