Neman

The Neman (based on Russian spelling), Nioman (Belarusian), Nemunas (Lithuanian), Niemen (Polish), or Memel (German), is a river in Europe that rises in central Belarus and flows through Lithuania then forms the northern border of Kaliningrad Oblast, Russia's western exclave, which specifically follows its southern channel. It drains into the Curonian Lagoon, narrowly connected to the Baltic Sea. The long Neman is a major Eastern European river. It flows generally west to Grodno within of the Polish border, north to Kaunas, then westward again to the sea.

The largest river in Lithuania, and the third-largest in Belarus, it is navigable for most of its length. It starts from two small headwaters merging about southwest of the town of Uzda – about southwest of capital city Minsk. Only , an eastward meander, contributes to the Belarus–Lithuania border. Thereafter the river includes notable loops along a minor tectonic fault.

Its drainage basin settled in the late Quaternary to be roughly along the edge of the last glacial sheet so dates to about 25,000 to 22,000 years BC. Its depth varies from in its upper courses to in the lower basin. Provided by Wikipedia
