Desna

The fourth one in Top 10 Longest Rivers in Ukraine that Toplist would like to introduce to you is Desna. The Desna is a major left-tributary of the Dnieper River in Russia and Ukraine. In the Old East Slavic language, its name means "right hand." It stretches for 1,130 kilometers (702 miles), and its drainage basin covers an area of 88,900 square kilometers (34,324 sq mi).

The river's width in Ukraine ranges from 60 to 250 meters (200 to 820 feet), with an average depth of 3 meters (10 ft). At its mouth, the average annual discharge is 360 m3/s (13,000 cu ft/s). From early December to early April, the river freezes over and is navigable from Novhorod-Siverskyi to its mouth, a distance of about 535 kilometers (332 mi).

In June 2020, the river's water level reached its lowest recorded level in 140 years. This water level was 5 meters (16 feet) lower than normal for the time of year.

The Desna is a Russian river that originates in the Smolensk Heights of the Smolensk Oblast. The river's headwaters are in the Yelninsky District, east-southeast of Smolensk and not far from Yelnya, in a forest near the village of Naleti. The Desna then flows south through a low, swampy valley to Bryansk, where the river's right bank rises.

The river widened after its confluence with the Seym near the Russian-Ukrainian border, splitting into numerous smaller branches. Its right bank drops again near Chernihiv, and again near one of its tributaries, the Oster, where the Desna continues its journey through a low, muddy plain until it reaches the Dnieper River near Kyiv.
