Chernorechensky reservoir, Reservoir in Balaklava District, Sevastopol

The Chernorechensky reservoir lies in the centre of the Baydar Valley near the village of Ozyornoye, on the Chernaya River. It is 3.45 km long and 3.55 km wide, with a surface area of 6.04 km², an average depth of 10.7 m and a maximum depth of 31.7 m. Its volume is 64.2 million m³, and its 36-metre dam is a gravity spillway that works automatically.

Surveys on the Chernaya River for supplying Sevastopol with water were carried out in 1938–1940, and on 26 April 1949 the USSR Council of Ministers ordered a reservoir in the centre of the Baydar Valley. The 28 m dam was finished in 1956, collecting 33.2 million m³. Between 1977 and 1984 the dam was raised to its present 36 m, making it the largest reservoir by volume in Crimea.

The area around the reservoir is quiet and typically less crowded, with flat terrain and mostly natural surroundings where you can observe birds and water. Access is generally straightforward, and it is worth checking water levels beforehand, as these fluctuate significantly depending on the season and rainfall.

In 2014–2015 wells were drilled near the reservoir; their water flows by gravity into it at 10,000–15,000 m³ per day. In 120 m from the water's edge, on the southern shore in the village of Rodnikove, stand the Skelskiye menhirs, a Bronze Age archaeological monument.
