Karakoro River, month by month
Highest water: September
Lowest water: from January to April. Best months to visit: from December to February.
From about 0.0 m³/s in the lowest month to 12 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.
