Italian river
At the mouth it carries 60 m³/s on average: an Olympic pool every 42 seconds. It drops from 690 m to 47 m, 5.5 m per kilometre on average. 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).

Nera, month by month
Highest water: from November to December
Lowest water: from July to August. Best months to visit: from May to September.
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.
