It begins on the north-eastern slopes of the Vlašić mountain's plateau, and the mouth opens at Šiprage, where the town's sawmill was.

[1][2][3] In the relatively narrow area there is a fertile and wide riverhead between Ćorkovac, Ilomska, Čudnić, Kovačevići's stream, Grabovička rijeka, Kobilja, Ugrić and other confluents of Vrbanja and the Ugar river.

[4] The crest of the riverhead directs towards the villages of Petrovo Polje, Imljani, Vlatkovići, and the Skender Vakuf Municipality.

Local inhabitants were killed and displaced, as well as all Bosniaks and Croats settlements at the mouth of Vrbanja river (Vrbas).

After the 1996, the destroyed villages in Šiprage's region are reconstructed by Battalion BELUGA (Belgium – Luxembourg – Greece – Austria), from IFOR/SFOR Mission.
