It is 300 km in length, its catchment area being 6730 km2 .  The Shchara River is the 5th longest river in Belarus. Bisenė or Bisena was a wooden fortress of the Grand Duchy of Lithuania during the Lithuanian Crusade.  It was one of the Lithuanian defensive outposts along the Neman River and was burned down by the Teutonic Order in 1283 and 1316.  Its location was long debated and often confused with Pieštvė, but after 1985 research of Romas Batūra it has been generally accepted to be Kartupėnai Hill Fort near the confluence of the Kartupis and Neman in Jurbarkas District Municipality, Lithuania.  After the burning down of Kolainiai in 1291 and Bisenė in 1316, Junigeda (Veliuona) became the western-most Lithuanian fortress along the Neman. Vilijampolė (popularly known in Lithuania as "Slabotkė") is an elderate in the city of Kaunas, Lithuania, located on the right bank of the Neris River and the Nemunas River, near their confluence.

The Current River forms in the southeastern portion of the Ozarks of Missouri and becomes a 7th order stream as it flows southeasterly out of the Ozarks into northeastern Arkansas where it becomes a tributary of the Black River, which is a tributary of the White River, a tributary of the Mississippi River.  The Current River is approximately 184 mi long and drains about 2641 sqmi of land mostly in Missouri and a small portion of land in northeastern Arkansas.  The headwaters of the Current River are nearly 900 ft above sea level, while the mouth of the river lies around 280 ft above sea level.  The basin drains a rural area that is dominated by karst topography, underlain by dolomite and sandstone bedrock with a small area of igneous rock southeast of Eminence, Missouri.  The annual daily mean discharge of the river near Doniphan, Missouri is 2815 cuft per second.  In 1964, over 134 mi (160 km) of the upper course of the river and its tributaries were federally protected as the Ozark National Scenic Riverways, the first national park in America to protect a river system. Rambynas is a hill on the right bank of the Neman River in Rambynas Regional Park, Pagėgiai Municipality, western Lithuania.  The current hill, about 46 m above sea level and about 40 m above the Neman, is a remnant of the larger hill that was destroyed by erosion.  The hill was known as sacred among locals and played a role in the ceremonies of pagan Lithuanians.  It is featured in many local legends and is protected by the state as a mythological object.  A large stone at the top of the hill, known as the altar stone, was destroyed by a miller in 1811.  Rambynas became popular with Prussian Lithuanians at the end of the 19th century who organized various events, most notably celebrations of the Saint Jonas' Festivals or Rasos (summer solstice), on the hill.  They rebuilt the altar in 1928.  The hill is popular with Lithuanian neo-pagans and hosts the annual celebrations of the summer solstice on 23 June. Archaeologists use the name Neman culture to refer to two archaeological cultures (7th to 3rd millennium BC) which existed in the Mesolithic and continued into the middle Neolithic.  Neman culture represents a continuation of the Swiderian culture and was replaced by the Corded Ware culture.  It was located in the upper basin of the Neman River (present-day northern Poland, southern Lithuania, western Belarus and Kaliningrad Oblast).  In the north, the Neman culture bordered the Kunda culture during the Mesolithic and the Narva culture during the Neolithic.
