The Drina flows between the mountains of Zvijezda and Sušica and it is flooded by the artificial Lake Perućac on the northern slopes of the Tara mountain, created by the Bajina Bašta power plant. The villages of Prohići and Osatica (in Bosnia and Herzegovina) are located on the lake, as well as the ruins of the medieval town of Đurđevac. The river is dammed at the village of Perućac, where a strong well springs out from the Tara mountain, flowing into the Drina as a waterfall. In addition, the waters of Drina are used for several fish ponds for the rainbow trout spawning.
