River in Donetsk Oblast, Ukraine
At the mouth it carries 8.2 m³/s on average: an Olympic pool every 303 seconds. It drops from 133 m to -11 m, 0.7 m per kilometre on average. Its basin covers 5,070 km², about the size of TT. 1.6 million people live in it. Highest water: from March to April; lowest: from December to February and October. No large dam holds it back: it is one of the world's free-flowing rivers.

Kalmius, month by month
Highest water: from March to April
Lowest water: from December to February and October. Freezing months (average below −4 °C): January. Best months to visit: from May to September.
From about 8.0 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.
