Crna River (Željeznica)
Crna River is a right-hand tributary of the Željeznica, which is a tributary of the Bosna River, in Bosnia, Bosnia and Herzegovina. It springs between the slopes of Jahorina and Trebević. It arises from two streams: Duboki Creek and an unnamed one, both at an elevation of around 1320 m.
The water of the river is very clean, so that its utilization is planned in order to supply Sarajevo with drinking water by constructing a dam and a plant and connection to the water supply network.
