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 15 kilometers (9 mi) southwest of the town ofUzda– about 55 km (34 mi) southwest of capital cityMinsk.Only 17 kilometres (11 mi), an eastward meander, contributes to theBelarus–Lithuania border.Thereafter the river includes notable loops along a minor tectonic fault.

Itsdrainage basinsettled in the lateQuaternaryto be roughly along the edge of the lastglacialsheet so dates to about 25,000 to 22,000 years BC. Its depth varies from 1 meter (3 ft 3 in) in its upper courses to 5 meters (16 ft) in the lower basin.

Nemunas loops

500litasbanknote featuring Nemunas loops

Due to their location, "the Nemunas loops" are often described using the Lithuanian name for the river. In 1992Nemunas Loops Regional Parkwas founded. Its goal is to preserve the loops (Lithuanian:vingis) that the river makes in thePuniaforest. NearPrienai,the river makes a 17-kilometer-long (11 mi) loop (like a teardrop) coming within1.2 km (3⁄4mi) of completing the loop. Nemunas flows along the double bend betweenBalbieriškisandBirštonasfor 48 km (30 mi) and then moves in a northerly direction for only4.5 km (2+3⁄4mi). The loops are not conventional rivermeanders;they follow underlyingtectonicstructures. Thefaultsare the source of local mineral springs.The area is historically and culturally significant. Its castles served as the first line of defense against forays by theTeutonic knights.

Delta

Main article:Nemunas Delta

At itsdeltaNemunas splits into a maze of river branches and canals mi xing withpoldersandwetlandsand is a very attractive destination foreco-tourism.The four maindistributariesare Atmata, Pakalnė, Skirvytė (the southern mouth, marking the international border) and Gilija. The river plays a crucial part in the ecosystem of theCuronian Lagoon.It provides the main water inflow to the lagoon and keeps the water almost fresh. This allows fresh water andbrackish wateranimals to survive there. As the delta extends north the lagoon opposite narrows. Since the delta is in Lithuania, it is often referred to asNemunas Delta.Nemunas Delta Regional Parkwas created in the delta in 1992.

Significance in culture

Ptolemyreferred to Neman as Chronos (although competing theories suppose Chronos was in factPregolya).

The river has lent its name to theNeman Culture,aNeolithicarchaeological subculture.

Napoleon and his army crossing the Neman in June 1812

InGerman,the part of the river flowing through historicPrussiahas been calleddie Memelat least since about 1250, whenTeutonic KnightsbuiltMemelburgcastle and the town ofMemelat the mouth of the Curonian Lagoon, naming it after the indigenous name of the river, Memel. The city of Memel, now in Lithuania, is known today asKlaipėda(confusingly, another city of Memel was on the Dange River, now called theDanė). In German road maps and lexika, only the 112-kilometer (70 mi) section within Prussia (starting atSchmalleningken) was named Memel; the bulk of the river was Niemen.

The border between theState of the Teutonic Orderand Lithuania was fixed in 1422 by theTreaty of Lake Melnoand remained stable for centuries. TheTreaty of TilsitbetweenNapoleonandTsarAlexander Iwas signed on a raft in the river in 1807.Napoleon's crossing at the outset of the 1812French invasion of Russiais described inWar and Peaceand also mentioned inPan Tadeusz.In 1919, theTreaty of Versaillesmade the river the border separating theMemel Territoryfrom GermanEast Prussiaas of 1920. At that time, Germany'sWeimar Republicadopted theDeutschlandliedas its officialnational anthem.In the first stanza of the song, written in 1841, the river is mentioned as the eastern border of a (then politically yet-to-be united)Germany:

Lithuanians refer to Nemunas as "the father of rivers" (Nemunasis a masculine noun in Lithuania). Countless companies and organizations in Lithuania have "Nemunas" in their name, including afolkloreensemble, a weekly magazine about art and culture, asanatorium,and numerous guest houses and hotels. Lithuanian and Polish literature often mention the Nemunas. One of the most famous poems byMaironisstarts:

Kur bėga Šešupė, kur Nemunas teka	Where theŠešupėruns, where the Nemunas flows
Tai mūsų tėvynė, graži Lietuva	That's our fatherland, beautiful Lithuania

Smaller rivers and rivulets in Lithuania with namesmorphologically derivedorcognateare the Nemunykštis, Nemuniukas, Nemunynas, Nemunėlis and Nemunaitis.

Theetymologyis disputed: some say that "Nemunas" is an old word meaning "a damp place",while others that it is "mute, soundless river" (fromnemti, nėmti"to become silent", alsomemelis, mimelis, mėmė"slow, worthless person" ).The name is possibly derived from the Finnic wordniemi"cape".

Art critics praised its depiction in the paintings byMichał Kulesza.

Economic significance

Schematic map of Kaunas Reservoir area

Much of the river is used for fishing, hydropower generation, water supply, industry, agriculture, recreation, tourism, and water transport.

Lithuania has tabled local plans to dredge it, below Kaunas, to make it more consistently usable.

The largest cities on the river areGrodnoin Belarus,AlytusandKaunasin Lithuania, andSovetskin the Kaliningrad Oblast of Russia. The river basin has a population of 5.4 million inhabitants. Industrial activities in theBelarusiansection include metal processing, chemical industries, pulp and paper production, and manufacturing of building materials, as well as food-processing plants. In Lithuania, the city of Kaunas, with about 400,000 inhabitants, is the country's principal user of the river; the local industries that impact the river are hydropower generation, machinery, chemical,wood processingand paper production, furniture production, textile and food-processing. In Kaliningrad, industrial centers near the river include Sovetsk and Neman, which have large pulp and paper production facilities.

AboveKaunasadamwas built in 1959 to serve theKaunas Hydroelectric Power Plant.The resultingKaunas Reservoir(Lithuanian:Kauno marios) is the largest such lake in Lithuania. It occupies63.5 km²(24+1⁄2sq mi); its length is 93 km (58 mi); its greatest depth is 22 m (72 ft). The reservoir is a popular destination for Lithuanianyachting.

TheAugustów Canal,built in the 19th century, connects Neman toVistulariver.

Biological communities

Fish found include the:perch,pike,zander,roach,tench,bream,rudd,ruffe,andbleak.

Its tributaries have borne stoneloach,three-spinedstickleback,minnows,trout,sculpins,gudgeon,daceandchub.

Atlantic salmonmigrated upstream to spawn; however, dams on the river, most of them built in the 20th century, have depleted them. The dam at Kaunas does not providefish ladders.The spawning season took place in the fall. Ethnographic studies, from before the dams, state night fishing, using torches andharpoons,was a common technique.

Environmental issues

Neman sunset

A report by theSwedish EPA(Environmental Protection Administration) rates the river's quality in Lithuania as moderately polluted to polluted. High concentrations of organic pollutants,nitratesandphosphatesoccur in parts of the river. Environmental issues include water quality (eutrophicationand pollutants largely due to outdated technology sewage treatment works), changes in the hydrological regime, and flooding control. The environmental problems in each of the countries that make up the basin are slightly different. In Belarus, the main problems are oil products as well as nitrogen andBOD(biological oxygen demand). The environmental issues in the Kaliningrad section include high concentrations of BOD, lignosulphates, andnitrogen.In Lithuania, theKaunas Hydroelectric Power Plantbarrage affects theriparianecosystem.

Co-operation which would be beneficial is complicated by the geographical split between three nations but water quality improvement initiatives are underway.
