The Bistrica (Serbian Cyrillic: Бистрица), also Dobropoljka, is a left tributary of the Drina. It springs out of the massif of Treskavica mountain. The source-group is made up of a dozen smaller springs and streams, while the Bistrica spring itself is located in a cave at 1280 m above sea level at the site of Siljevice.^[1] It passes through Dobro Polje where it is called Dobropoljka or Dobropoljska Rijeka.^[2] Just beneath Dobro Polje, river creates a huge natural arch through the limestone rock of its canyon, which is protected Nature Monument.^[3]

The length of the river is 43.3 km, its catchment area is 425.0 km², and its mouth is located at Vučijak locality in Brod na Drini, near Foča, at 394 m above sea level. The most significant left tributaries are the Drazenica river at 10.8 km long, and the Miljevka river at 13.2 km long, while the right tributaries are the Oteša river at 15.2 km long, and the Govza river at 21.9 km long.^[1]
