Its basin covers 35,545 km², about the size of TW. 1.6 million people live in it. Highest water: from February to March; lowest: from June to September.

Mantaro River, month by month
Highest water: from February to March
Lowest water: from June to September. Best months to visit: from April to May and from September to November.
From about 290 m³/s in the lowest month to 1,500 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.
