Nemunas loops
Due to their location, "the Nemunas loops" are often described using the Lithuanian name for the river. In 1992 Nemunas Loops Regional Park was founded. Its goal is to preserve the loops (Lithuanian: vingis) that the river makes in the Punia forest. Near , the river makes a loop (like a teardrop) coming within of completing the loop. Nemunas flows along the double bend between Balbieriškis and Birštonas for and then moves in a northerly direction for only . The loops are not conventional river ; they follow underlying structures. The faults are 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 the .


Delta
At its Nemunas splits into a maze of river branches and canals mixing with and and is a very attractive destination for . The four main are Atmata, Pakalnė, Skirvytė (the southern mouth, marking the international border) and Gilija. The river plays a crucial part in the ecosystem of the . It provides the main water inflow to the lagoon and keeps the water almost fresh. This allows fresh water and animals to survive there. As the delta extends north the lagoon opposite narrows. Since the delta is in Lithuania, it is often referred to as Nemunas Delta. Nemunas Delta Regional Park was created in the delta in 1992.

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 Belarus, and 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 section 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, and 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.

Above a was built in 1959 to serve the Kaunas Hydroelectric Power Plant. The resulting () is the largest such lake in Lithuania. It occupies ; its length is ; its greatest depth is . The reservoir is a popular destination for Lithuanian .

The Augustów Canal, built in the 19th century, connects Neman to river.

Environmental issues
A report by the (Environmental Protection Administration) rates the river's quality in Lithuania as moderately polluted to polluted. High concentrations of organic pollutants, and occur in parts of the river. Environmental issues include water quality ( and 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 and BOD (biological oxygen demand). The environmental issues in the Kaliningrad section include high concentrations of BOD, lignosulphates, and . In Lithuania, the Kaunas Hydroelectric Power Plant barrage affects the .

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