The lake was created as a reservoir for the Bajina Bašta Hydroelectric Power Plant, which opened in 1966.
The water temperature in the lake remains significantly lower than typical surface water temperatures due to the deep-water intake from the Drina River.
Perućac Lake is narrow and winding, flowing through a deep canyon that reaches depths of up to 70 meters in certain sections.
The floating beach is constructed to be modular, allowing the facility to remain functional regardless of the drastic water level fluctuations required for power generation.
Pontonska Plaža Na Jezeru Perućac is a floating beach platform situated on the surface of Perućac Lake, formed by the damming of the Drina River. The beach consists of a series of interconnected wooden pontoons that rise and fall with the lake's water level. It serves as a primary swimming and sunbathing access point in the Rastište area near the border between Serbia and Bosnia and Herzegovina. The water depth beneath the pontoons is significant due to the canyon geography, providing clear, cool swimming conditions. Visitors use the site as a starting point for renting pedal boats or viewing the surrounding Tara National Park landscape. The site is maintained as a seasonal recreational facility during the warmer months.
The edge of the pontoon platform looking toward the steep, forested cliffs of the Drina Canyon.
Bring water shoes, as the edge of the pontoon can be slippery and entering from a platform differs from a gradual sandy shore.
There is very little natural shade on the floating pontoons, so bring portable sun protection.
Check the water level status if visiting during periods of heavy energy production, as it can affect dock access.
Do not attempt to swim across the main channel of the lake toward the Bosnian side, as it is a frequent transit route for tour boats and barges.
The pontoon facility is installed and operational only during the summer season; it is typically dismantled or inaccessible during winter months.
Standard swimming attire is required; jumping from the sides of the pontoons may be restricted based on local safety signage.
