Perućac features what is reputedly Serbia's smallest river — the Vrelo. It is known as the "year-long river", due to its length — 365 m — from its source to its end, with the length in metres corresponding to the number of days in a year. The Vrelo flows into the Drina just a few hundred metres downstream the dam.
During the summer days, Lake Perućac is the place where many of the residents of the surrounding area and the town of Bajina Bašta come to sunbathe, swim and fish. Perućac is also where the 56 km-long canyon of the River Drina begins.
