Its basin covers 4,100 km², about the size of CV. 3.0 million people live in it. Highest water: from April to May; lowest: from December to February. Its dams hold back little of its water (2.1% of a year's flow).

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

From about 210 m³/s in the lowest month to 510 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.
