It was created in 1981-1987. according to the project of the Ukrhydroproekt Institute. The gate of the Dniester hydroelectric power station is located 677.7 km from the mouth of the Dniester River ; the catchment area to the target is 40500 km². The flow rate is 274 m³ / s. The maximum flow rate for which the hydraulic system is designed is 13260 m³ / s.
Located in the Khmelnytsky , Chernivtsi and Vinnitsa regions of Ukraine. The dam of the Dniester hydroelectric station is located near the city of Novodnistrovsk, Chernivtsi region [1] .

- usable volume - 2.0 km³;
- mirror area - 142 km²;
- length - 194 km;

The reservoir was filled from the end of 1981 to 1987, which is associated with a long period of low water content.
The reservoir allows seasonal regulation of the Dniester runoff with a transition to an annual one and provides irrigation of 500 thousand ha of land. In addition, for 25 years, the settlements of Moldova and Ukraine , located on the banks of the Dniester below the Dniester hydroelectric station and to the Black Sea, have not suffered from catastrophic floods and spring ice jams.
The main purpose of the reservoir is hydropower . At the same time, protection of settlements from floods , water supply to the population, industry and irrigation are provided.
The Dniester hydroelectric power station with a capacity of 702 MW was built in the site of the reservoir hydroelectric complex.
Dniester reservoir (buffer)
20 km downstream from the Dniester hydroelectric station -1 near the village. Nagoryany (Vinnytsia region) Vinnytsia region built a buffer waterworks - Dniester reservoir (buffer) [1] :
- length - 19.8 km;
- total volume - 0.0324 km³;
- mirror area - 6.1 km²;
- maximum depth - 9 m;
- average depth - 5.3 m.
The Dniester reservoir (buffer) is intended for leveling releases from the Dniester reservoir (main) and their influence on the river. Dniester with daily and weekly power regulation of the Dniester hydroelectric station-1 .
The dam of the buffer reservoir has 12 spillways.
To the left of the dam, a small Dniester hydroelectric station-2 was built with a capacity of 40.8 MW.
The buffer reservoir is simultaneously the lower reservoir for the Dniester PSP .
Operation
The Dniester reservoir (main) and the Dniester reservoir (buffer), which are part of the Dniester complex waterworks (DKGU), are operated by the Dniester-Prut Basin Department of Water Resources . web.archive.org . Date of appeal April 16, 2019 .
The operation mode of the reservoirs is determined by the "Rules for the operation of the reservoirs of the Dniester complex hydroelectric complex (DKGU)." Due to the lag in actual water use from the design level, excess runoff can be used in the interests of any participant in the water management complex by decision of a permanent interdepartmental commission.
In order to prevent flooding in the downstream of DKGU, the average daily water discharge of the Dniester hydroelectric station (with the exception of floods) should not exceed 1000 m³ / s.
