Lake Tengiz is three times larger, than Lake Constance and dotted with undisturbed islands. The lake water is salty, as an out-flow is lacking. Not far away are the Korgaljinski Lakes fed by the Nura river. Having both, an in-flow and an out-flow, these lakes contain fresh water. In 1968 large sections were placed under protection. Unlike other lake regions, the Kazakhs are taking the matter seriously, an effort that deserves our praise, since most of the steppe lakes have been vandalised.
