The Nemunas River is used for a variety of purposes such as fishing, hydropower generation, water supply, industry, and agriculture, as well as recreation, tourism, and water transport.
There have been proposals to deepen its watercourse below Kaunas to make it more consistently usable.

The largest cities on the river are Grodno in Belarus, Alytus and Kaunas 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 Belarusian 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, wood processing 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 Kaunas a dam was built in 1959 to serve the Kaunas Hydroelectric Power Plant.
The resulting Kaunas Reservoir (Lithuanian: Kauno marios) is the largest such lake in Lithuania.
It occupies 63.5 km² (24 ¹⁄₂ sq mi); its length is 93 km (58 mi); its greatest depth is 22 m (72 ft).
The reservoir is a popular destination for Lithuanian yachting.

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