Nemunas

The Nemunas, sometimes known as the Nioman, Neman, or Memel, is the Longest River in Lithuania, and is a river in Europe that originates in central Belarus and runs through Lithuania before forming the northern boundary of Kaliningrad Oblast, Russia's western exclave, which follows its southern channel. It drains into the Curonian Lagoon, which is only tenuously connected to the Baltic Sea. It has a length of 937 kilometers (582 miles) and is considered a prominent Eastern European river. It runs mainly west to Grodno, about 12 kilometers (7.5 miles) from the Polish border, then north to Kaunas and west again to the sea.

It is navigable for the majority of its length and is the biggest river in Lithuania and the third-largest in Belarus. It begins with two minor headwaters that merge around 15 kilometers (9 miles) southwest of the village of Uzda – about 55 kilometers (34 miles) southwest of Minsk, the capital city. A 17-kilometer-long (11-mile-long) eastward meander adds to the Belarus–Lithuania boundary. Following that, the river makes noticeable loops over a small tectonic fault. Its drainage basin settled in the late Quaternary to be about along the border of the last glacial sheet and hence dates to between 25,000 and 22,000 years BC. It ranges in depth from 1 meter (3 ft 3 in) in the higher courses to 5 meters (16 ft) in the lower basin.
