Lake Lelång is part of the Dalsland Canal system and one of the largest lakes in the whole area. The southern part of the lake reaches the Värmland province border and the part to the north of this border calls for a separate fishing licence. Several streams empty into the lake, including the Greaströmmen and Blomälven rivers. Much of the shoreline is barren and mountainous. These sections are not only a pleasure to look at. They are exciting fishing sites.
Lake Lelång is a clear lake and its deepest parts are in the middle just south of Gustavsfors. The deepest point reaches 61 metres. Most of the shoreline is rocky, offering a barren wilderness character comprising forest, mountain and beautiful nature. The Skarsdalsbergen Nature Preserve is on the east side some kilometres north of Bengtsfors. The east side north of Kråkviken presents steep mountains and cliffs rushing into the water.
