Tara
The Tara is a river that flows through Montenegro and Bosnia and Herzegovina. It flows from the confluence of the Opasnica and Veruša rivers in Montenegro's Komovi Mountains, which are part of the Dinaric Alps. The total length is 146 kilometers, of which 141 kilometers are in or near Montenegro's border; it also forms the border between the two countries in several places. The Tara flows from south to north - north-west and joins the Piva at the border between Bosnia and Herzegovina and Montenegro, between the villages of Šćepan Polje (Montenegro) and Hum (Bosnia and Herzegovina), to form the Drina river (a branch of the Danube watershed).
The Tara River carves the Tara River Canyon, which is 78 kilometers long and 1,300 meters deep at its deepest point, and is the longest canyon in Montenegro and Europe, as well as the second longest in the world after the Grand Canyon. The canyon has been designated a UNESCO World Heritage Site. Durmitor National Park is located in the canyon. The river was named after the Illyrian Autariatae tribe, whose territory included the river valley in classical antiquity.
The Tara river is rich in endemic salmonid fish species, huchen (Latin: Hucho hucho), which are otherwise globally endangered, and, along with the Drina river and most of its tributaries, such as the Piva river before damming, the Bistrica, Ćehotina, Lim, Prača, Drinjača, Sutjeska, it is still Europe's prime habitats and spawning grounds.
