Caledon River, month by month
Highest water: from February to March
Lowest water: from June to September. Best months to visit: April and from September to December.
From about 38 m³/s in the lowest month to 350 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.
