The Ugar (, known as the Brzica until 1878) is a river of Bosnia, a tributary of the Vrbas river. It originates at the slopes of Vlaà ¡iÃÂ, upstream of Saà ¾iÃÂi and Melina villages (at around of 1,590 meters above sea level), a watershed area of Vrbanja, Ilomska and Bila rivers. The valley along the Ugar is known as Pougarje.
The Ugar's length is around 44.5 kilometres, and its catchment is around 328 km<sup>2</sup>. Its largest right tributaries are: PljaÃÂkovac, Ilomska, Kobilja, Zirin Potok and Kusin Potok (Ziro's and Kuso's creeks), and UgriÃÂ; left tributaries are the creeks: namely Luà ¾nica Potok, DediÃÂa Potok, AndrijeviÃÂa Potok, Bunar, Oraà ¡ki Potok, and KukaviÃÂki Potok.
At its source, the Ugar and its headwaters tributaries create a series of waterfalls. After short, but deep canyon (below the Babanovac plateau), it enters Pougarje, under the RanÃÂa Mountain. The Ugar then flows into a deep and long canyon under Skender Vakuf, around 20 kilometres downstream of Jajce. Notch of the Canyon is a very arduous and its maximal depth is (approximately) 500 m. The area in the valley along the Ugar, from Vitovlje to its Canyon, is marked as Pougarje
The area along the Ugar is known as Pougarje. Pougarje extends from the Vitovlje village to the Ugar's entrance into the canyon below Skender Vakuf. It is located between RanÃÂa Mountain (left) and rock's massif KoriÃÂanske stijene - Ugarske stijene (Ugar's rocks). From Vitovlje to Ugar's canyon it is known as the Lower (Donje) Pougarje, while the area on RanÃÂa's slopes is Upper (Gornje) Pougarje.
The valley (especially the slopes of RanÃÂa) is rich in coniferous and mixed deciduous-coniferous forests. The upper and middle part of the basin in the area still has the character of a salmonid water, now there are only (brown trout), while the huchen and grayling have disappeared in the recent past. The surrounding forests are inhabited by the big game (fox, wolf, bear, wild boar, and the others). At in a brushwood at the mouth of the Ilomska, in a protected hunting area, there is feeding place for carnivores.
