Physical Characteristics

Description Lake Balkhash, although slightly less saline than the conventional limit, is usually considered a saline lake. It is a terminal lake, i.e. it has no outlets. The two largest rivers flowing into Lake Balkash are the Ile and the Karatal. The drainage area of Lake Balkash and the Aral Sea are geographically separate, but the waterbodies shared many common species until massive local extinctions in the Aral.
