Lake Zavoj (Serbian Cyrillic: Завојско језеро, Latin: Zavojsko jezero) is an artificial lake in eastern Serbia, on the Visočica river. It was created in 1963 after a major landslide which dammed the river and the natural dam was later replaced with a hydroelectric dam "Zavoj".

Location

Lake Zavoj is located in eastern Serbia, in the northern part of the Visok region, close to the Serbian-Bulgarian border. Lake in the valley of the Visočica river which is both its major tributary and outflow, between the mountains of Stara Planina on the north and Vidlič on the south. Lake is located 16 kilometers north of the town of Pirot, close to the Visočica mouth into the Temštica river and is not well connected with the rest of Serbia. Settlements in the vicinity of the lake, which is among the least populated in the entire Serbia, include Novi Zavoj, Velika Lukanja and Pakleštica.

History

On February 25, 1963 a huge landslide from the sunny side of the Stara Planina rushed into the valley of the Visočica river and dammed a river creating a natural earth dam which was 500 meters long and 50 meters high. Reservoir was created behind the dam, flooding the village of Zavoj. This original natural lake was dried, the natural dam was consolidated and the artificial lake was recreated, this time as a reservoir for the hydroelectric power plant "Zavoj". The village of Novi Zavoj was built on the higher ground instead of the flooded old village of Zavoj.

Immediately after the dam was finished, Serbian government began a project of conducting waters from Temštica's upper course (Toplodolska reka) into the lake. Project was continued in the early 2000s but the local population in the watershed of Temštica protested claiming that over 80% of the water was already taken out of their river and that further catchment of the water from it woul result in an ecological catastrophy, especially in the canyon of Temštica popularly called "Little Colorado". As a result of this, municipality of Pirot officially opposed the government's decision in 2004 and 2006, but the government insisted on continuing the project. In protest, population of the village of Temska boycotted the Serbian parliamentary elections in January 2007.

Paleontological site

The site, located at an altitude of 700-750 meters, has been discovered in 2004 and the preliminary research began in 2005 with the help of German paleobiologists from Freiburg. In the Upper Triassic, 230 to 200 million years ago, the area was a shallow, ending part of the large tropical sea, the Tethys Ocean. The mud and sediments petrified in the form of plates which are rich in remains of mollusc shells (which have been found on the slopes of the Stara Planina as high as over 1.440 meters]], sea worms, snails and other marine animals (sea crocodiles, sharks, giant molluscs) with indications that fossils of the dinosaurs can be found also. In some sections, Triassic sediments are over 7 meters deep.
