The Desna (Russian: Десна; Ukrainian: Десна) is a river in Russia and Ukraine, a major left-tributary of the Dnieper. Its name means "right hand" in the Old East Slavic language.[citation needed] It has a length of 1,130 km (702 mi), and its drainage basin covers 88,900 km2 (34,324 sq mi).[1]
In Ukraine, the river's width ranges from 60 to 250 metres (200 to 820 ft), with its average depth being 3 m (10 ft). The mean annual discharge at its mouth is 360 m3/s (13,000 cu ft/s).[1] The river freezes over from early December to early April, and is navigable from Novhorod-Siverskyi to its mouth, a length of about 535 km (332 mi).[1]
The water level of the river reached its lowest recorded point in 140 years in June 2020. This water level was 5 m (16 ft) below normal for that time of year.[2]
