Lake Balkana
Republika Srpska
Lake Balkana is an artificial lake comprising two connected oval basins, known as the Upper (larger) and Lower (smaller) lakes, with a total surface area of approximately 56,000 square meters. Located on the slopes of Lisina mountain near Mrkonjić Grad in Republika Srpska, Bosnia and Herzegovina, the lake is fed by several mountain springs and two streams, Cjepalo and Skakavac. Its outflow is the Crna Rijeka (Black River), which flows northward through Mrkonjić Grad and eventually joins the Vrbas River. Surrounded by lush oak and conifer forests as well as pastures, the lake offers a tranquil natural setting. The smaller lake area is developed as a swimming spot, with water temperatures reaching around 20°C in July and August, making it suitable for bathing. The larger lake is rich in fish species such as trout, grass carp, and tench, attracting anglers. The lake is part of the Upper Sana-Pliva tourist zone and is a popular local excursion destination, offering opportunities for relaxation, fishing, and enjoying the natural beauty of the region.
