Abstract
The water and hydrochemical balance of Shira and Itkul lakes located in the arid (steppe) zone in the Khakasia Republic (Russian Federation) has been calculated. Existence of hydraulic connection of these lakes is shown. Lake Itkul can be considered as flowing reservoir. Outflow of water from Itkul to Shira is 6791 thousand m3/year, and outflow of the dissolved salts is 35 697 tonn/year. In this case, Lake Shira can be only considered as unflowing reservoir with transpiration mechanism of water chemical composition formation. Lake Itkul appears to be a flowing reservoir. In Itkul salt concentration is not such as occurs in Lake Shira because of less influence of evaporation and time of water-rock interaction. This mechanism may be similar for other arid zones in Northern and Central Asia.
