What is the longest river in Norway?
Skarnes
Skarnes is divided by the river Glåma, the longest river in Norway. The river Oppstadåa runs into Glåma at Skarnes. Oppstadåa is one of the longest rivers running both ways in Norway. This effect is created by floods, dams, melting snow in the mountains in spring and low water during summer.
Klarälven
It emanates from Lake Rogen in Härjedalen, Sweden, and then passes through the Norwegian Hedmark, where it flows through the lake Femunden. There it is known as Femundelva and Trysilelva (before the nationalistic movement in the 19th century the river was called Klara even in Norway; today it is called Femundelva in the municipality of Engerdal and Trysilelva in the municipality of Trysil, reflecting strong local patriotism in Norway). The rest of the river, the longest part, flows through Värmland to ultimately discharge in a delta into Vänern at Karlstad.
