River
At the mouth it carries 175 m³/s on average: an Olympic pool every 14 seconds. It drops from 195 m to 133 m, 0.7 m per kilometre on average. Its basin covers 581 km². 1.1 million people live in it. Highest water: from November to December. No large dam holds it back: it is one of the world's free-flowing rivers.

Sutla, month by month
Highest water: from November to December
Best months to visit: from May to September.
From about 97 m³/s in the lowest month to 290 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.
