Uvac originates in Caričina village, at some 1460 meters above the sea level, and empties into the Lim river at around 440 meters above the sea level.
Uvac valley is partly submerged due to construction of three dams and creation of artificial lakes: Uvačko Lake, Zlatarsko lake and Radoinjsko lake.
Uvac lake was created by building a dam in Akmačići village, at the altitude of 985 meters. The dam is 160 meters long and 110 meters high, length of the lake is 25 kilometers.
At 885 meters altitude, in Kokin Brod near Nova Varoš, Uvac was held back by another barrier that is 83 meters high and 1.264 meters long. The lake is 27 kilometers long.
The third lake, situated in the lowest part of the river course is Radoinjsko lake, at the 805 meters altitude. The dam is 40 meters high and 150 meters long. Wedged between steep limestone banks, the lake is 11 km long.
Water from accumulated lakes is mainly used for production of electricity and water supply. “Uvac” Special nature reserve is a high quality natural resource with the capacity of 500 million cubic meters of drinking water.
