Sergeyev Dam or Sergeyevka Dam (Kazakh: Сергеев бөгені; Russian: Сергеевское водохранилище) is a gravity dam in Shal akyn District, North Kazakhstan Region, Kazakhstan.[2]
The dam is located a little upstream from Sergeyev town on the Ishim River.[3] It has a road bridge, as well as a pumping station for the Sergeev city water supply, which is part of the Ishim Water Supply Network (Kazakh: Есіл су құбыры) that operates in the North Kazakhstan and Akmola Regions.[4]
The Sergeyevka Dam was commissioned in 1968 at the time of the Kazakh SSR. It had a hydroelectric power station with an installed power generation capacity of 2 MW. The hydroelectric power station building has a bottom spillway. The reservoir of the dam has a maximum storage capacity of 693000000m2 and a surface area of 117km2. The Imanburlyq, a tributary of the Ishim River, has its mouth in the reservoir.[2]
Currently the power station has a capacity of 3.5 MW with two propeller turbines connected to VGSP 213/29-14 generators with a capacity of 1.23 MW each. The average annual electricity generation is 16 million kWh. The dam is owned by RSE "Kazvodkhoz", which manages 78 reservoirs in Kazakhstan.[1]
