Lake Bohinj is the largest permanent and natural lake in Slovenia, which lies in the Julian Alps in the northwest of the country. The main tributary of the lake is Savica, which flows into the lake in the western part of the lake basin at Ukanc. The lake is flowing – from the lake the river Jezernica flows, which, after less than 100 m, along the left side, flows from Most, flowing from Voj, forms the river Savo Bohinjko.
At the northern edge of the lake there are several underwater karst springs, among which the best known is Govic. The coast is surrounded by Ribčev Laz and Ukanc, and in the vicinity of Stara Fužina, all belong to the Bohinj Municipality. Agriculture as a traditional economic activity has largely replaced tourism in the wider area of the lake.
