Tributary of the Tarn in France

At the mouth it carries 55 m³/s on average: an Olympic pool every 45 seconds. It drops from 737 m to 106 m, 3.3 m per kilometre on average. Its basin covers 3,497 km², about the size of CV. 210,000 people live in it. Highest water: from December to February. Dams and reservoirs hold back a large share of its water (11% of a year's flow).

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

From about 13 m³/s in the lowest month to 83 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.
