Kusmuryn
Kusmuryn is a long, shallow lake in the northern Turgay depression, crossed from south to north by the Ubagan River. Its waters change with the seasons: spring inflow freshens the lake, while in dry periods it becomes more saline and contracts. Reeds line the shallows, offering shelter to waterbirds. The lake forms a conspicuous wetland in the open steppe of northern Kazakhstan.
