Namsen River

a river in Norway. It is 210 km long and drains an area of 6,200 sq km. The Namsen issues from Lake Namsvatn, forms many rapids throughout its course (such as the 32-meter Fiskemfoss waterfall), and flows into Nams Fjord of the Norwegian Sea. In its middle course the discharge is 155 cu m per sec. A hydroelectric power station is on the river, which is used for floating timber and salmon fishing. The port of Namsos is on Nams Fjord.
