River in Ukraine and Russia
At the mouth it carries 19 m³/s on average: an Olympic pool every 132 seconds. It drops from 146 m to 122 m, 0.1 m per kilometre on average. Its basin covers 5,850 km², about the size of BN. 991,000 people live in it. Highest water, with the snowmelt: from April to June; lowest: from December to March. No large dam holds it back: it is one of the world's free-flowing rivers.

Sudost, month by month
Highest water: from April to June
Lowest water: from December to March. Freezing months (average below −4 °C): from December to February. Melting snow makes up much of its water. Best months to visit: from May to August.
From about 71 m³/s in the lowest month to 310 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.
