Nemunas loops

The name is possibly derived from the Finnic word ''niemi'' "cape". Art critics praised its depiction in the paintings by Michał Kulesza.

Economic significance

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 are

in Lithuania, and Sovetsk in the Kaliningrad Oblast of Russia. The river basin has a population of 5.4 million inhabitants. Industrial activities in the
