'''Lake Chagan''' (or '''Lake Balapan'''), [[Kazakhstan]], is a [[lake]] created by the [[Chagan (nuclear test)|Chagan nuclear test]] fired on January 15, 1965, part of the [[Nuclear Explosions for the National Economy]]. Its water comes from the [[Chagan River (tributary of Irtysh River)]]. Often referred to as &amp;quot;Atomic Lake,&amp;quot; the crater lake's volume is approximately {{convert|100000|m3|acre.ft|abbr=on}} and the lake is still [[radioactive]]. To the south, the rim of the crater holds back the waters of a second reservoir.&lt;br /&gt;
