Its basin covers 1,293 km², about the size of MQ. 251,000 people live in it. Highest water: March; lowest: from December to February and October. No large dam holds it back: it is one of the world's free-flowing rivers.

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

From about 18 m³/s in the lowest month to 260 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.
