Its basin covers 4,280 km², about the size of CV. 283,000 people live in it. Highest water: from November to December; lowest: from July to August. Dams and reservoirs hold back a large share of its water (23% of a year's flow).

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

From about 20 m³/s in the lowest month to 110 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.
