Madre de Dios River, month by month
Highest water: from February to March
Lowest water: from July to October. Best months to visit: from May to August.
From about 2,000 m³/s in the lowest month to 12,200 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.
