The river os 75 km long and the catchment area (702 km2) has only few lakes, so the water level can change quite rapidly in the river. Silveråns nature reserve area is located near Jönköping where the river meanders in the shadows of variable forest areas and steep ravins. The water quality is high and the river has a unique and rich water fauna because of the high currents and multiple biotopes. Trout and pearlmussel populations have many breeding areas due to the stream bed that consists of sand, gravel and rocks. Also the strandzone provides vital substance for the stream ecosystem.
