Lake Chagan, created by a Soviet nuclear test -

the site for the Chagan shot was the dry bed of the Chagan River on the edge of the Semipalatinsk Test Site (STS) in Kazakhstan. The shot location was chosen so that the crater lip would form a dam in the river during its period of high flow in the spring. The crater formed by the Chagan explosion had a diameter of 408 m and a depth of 100 m. A major lake (10,000,000 m 3 ) was quickly formed behind the 20-35 m high upraised lip. Shortly after the explosion, earthmoving equipment was used to cut a channel through the lip so that water from the river could enter the crater.
