Фёдоровское водохранилище, Reservoir in Kazakhstan

Fedorovskoe Reservoir is an artificial water body on the outskirts of Karaganda created by flooding a coal mining site. The body of water reaches depths of about 65 meters, while shallow areas near the shore allow for safe swimming and wading.

The reservoir was created by flooding the Fedorovsky coal open pit at the end of 1960. Filling of the former Mikhailovka mine's coal-depleted seam with water from the Sokyr River began in 1966 and reached its normal level in 1969. Since 1981, water has also been supplied via a pumping station from the Irtysh–Karaganda Canal.

The reservoir lies in southern Karaganda, near the Novaya Ala, Bolshaya Mikhaylovka, Fedorovka and South-East residential areas. Its water is used to irrigate many suburban garden plots. A rescue station and yacht club operate on the reservoir, and in 2015 the city began transferring the shoreline to the parks authority for a recreation zone.

The reservoir filled the worked-out coal seam of the former Mikhailovka mine: flooding began in 1966 and the water reached its normal level in 1969. Its deepest point is close to 70 metres, and in winter the ice grows to about one metre thick. The water is fresh, with mineralisation around 1 g per litre, and slightly brackish.
