Dalälven

The Dal River is a river in central Sweden that flows from the north of Dalarna and runs into the sea in northern Uppland; it is commonly considered to be the southern border of Norrland, however only the last part correlates with Limes Norrlandicus . The northern part is split into two rivers: Österdalälven and Västerdalälven. The two connect in Djurås. It is over 520 kilometres long — the second longest river in Sweden, and has a hydropower potential of 1420 megawatts, of which 2/3 is utilized. The largest power plant is located at the Trängslet Dam. Dalälven has been significant historically as a raft transport route.
Nedre Dalälven River Landscape, Sweden, covers 308,000 hectares with a mixture of wetlands, rivers, lakes, flood plains and productive forests. It includes Lake Hovran and Färnebofjärden Bay Ramsar site.
