Zavojsko Lake
Pirotski okrug
Zavojsko Lake is an artificial reservoir located in southeastern Serbia, approximately 17 km northeast of Pirot, on the Stara Planina mountain. It was formed in 1963 when a large landslide created a natural dam on the Visocica River, which was later reinforced by the construction of an artificial dam. The lake submerged the former village of Zavojsko, giving the lake its name. It is fed primarily by the Visocica River along with tributaries Gostuska and Belska. The lake's water is utilized to generate electricity at the Pirot Hydroelectric Power Plant through a tunnel system. The lake is a favored excursion spot for locals from Pirot and Nis due to its scenic surroundings and natural beauty. Its formation is geologically significant as an example of a colluvial (landslide) lake, a rare phenomenon in Serbia. The lake's length reaches over 7 km with an irregular shoreline and a maximum depth of approximately 60 meters after the dam construction. The surrounding area includes several small villages and is part of the mountainous landscape of Stara Planina. The lake's creation was a result of heavy winter precipitation and rapid snowmelt, which destabilized the slopes and caused a massive earth movement that blocked the river. Due to the potential risk of dam failure and flooding downstream, authorities intervened to stabilize and heighten the natural dam, leading to the current reservoir. Today, Zavojsko Lake is not only a hydropower resource but also a popular natural retreat offering picturesque views and outdoor activities.

Histoire
Zavojsko Lake originated in February 1963 following a massive landslide caused by heavy rain and rapid snowmelt, which created a natural dam on the Visocica River.
This natural dam initially held back the river water, flooding the area and submerging the village of Zavojsko.
Due to the instability of the natural dam and the risk of catastrophic flooding downstream, military and engineers intervened to breach and stabilize the dam.
Subsequently, an artificial dam was constructed to reinforce the natural barrier, creating the current reservoir.
The lake was also integrated into the regional hydropower system, with a tunnel and pipeline delivering water to the Pirot Hydroelectric Plant.
Over time, the lake has become a notable geographic and touristic feature in southeastern Serbia.
