Its basin covers 8,000 km², about the size of PR. 864,000 people live in it. Highest water: from November to December; lowest: August.

Tanaro, month by month
Highest water: from November to December
Lowest water: August. Best months to visit: from June to September.
From about 93 m³/s in the lowest month to 240 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.
