Lagan, a river in Sweden

The rivers in Denmark are few and they rarely swell, as Lagan does.
Lagan River is a popular place for salmon fishing.
‘The Lagan is one of four main west coast rivers in south-western Sweden besides Göta river. It is with 244 kilometres one of the longest rivers in southern Sweden.
People have been following the river from the coastal areas since the Viking Age and settling in its vicinity.
Along Lagan was a trading route, the so-called Lagastigen, which is now part of the road E4.’ Wikipedia.
