Water (estimated flow)Air (average) Rain (mm)Best months

From about 2.5 m³/s in the lowest month to 150 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.
