The dam is partly concrete and partly sprinkled. The broken concrete part consists of a spillway dam and two dams with power plants. The dam is 78 meters high above the terrain, but if we include the depth of the foundations, its total height is then 106 meters. The lake, which was created by damming, has an area of 2,850 km2 and a volume of 45.5 km3.
The first power plant, which is located between the spillway part and the second of the power plants, has installed 12 units with an output of 350 MW and two smaller operating units with an output of 2 x 22.5 MW. The second-generation power plant has 11 units installed, but in this case with an output of 375 MW.
