Lake Chagan (Kazakh: Шаған, Shaǵan) or Lake Balapan, Kazakhstan, is a lake created by the Chagan nuclear test fired on January 15, 1965, part of the Nuclear Explosions for the National Economy. A 140 kiloton device was placed in a 178-metre (584 ft) deep hole in the dry bed of the Chagan River. The blast created a crater 400 m (1,300 ft) across and 100 m (330 ft) deep with a lip height of 20 to 38 m (66 to 125 ft).; it is often referred to as "Atomic Lake".

The lake's water comes from the Chagan River (tributary of Irtysh River). The crater lake's volume is approximately 10,000,000 m3 (350,000,000 cu ft)[1]. To the south, the rim of the crater holds back the waters of a second reservoir.
