Bylkyldak (Kazakh: Былқылдақ; Russian: былкылдак),[1] also known as Balkyldak[2] is a salt lake in Pavlodar District, Pavlodar Region, Kazakhstan.[3]
The lake lies within an industrial zone 11 kilometers (6.8 mi) to the north of Pavlodar town.[4][5]
Geography
Bylkyldak is a natural lake part of the
Koryakovka is located 8.5 kilometers (5.3 mi) to the east.[4]
The lake was used as a reservoir by a
Kazakh SSR which operated until 1993. Nowadays the sediments of the lake are highly contaminated with mercury. A clay wall was built along the western shore to prevent the polluted Bylkyldak water to reach the oxbow lakes of the Irtysh to the west. Close to the northeast there is an artificial reservoir.[6][7][4]
Ecology
Despite warnings from environmentalists, the lake is used by local people for swimming in the summer. Fish caught in Bylkyldak, such as
dace, tench and crucian carp are heavily contaminated with mercury, but they are eaten by locals.[6] The lake is also visited by wild ducks, which are hunted and consumed by local people as well.[8]
