The object of the study is the Taloe lake tract (Republic of Khakassia), which is an isolated hollow periodically filled with precipitation, melt and groundwater. This basin includes two temporary reservoirs – western and eastern, with dimensions of 3300×960 m and 1610×385 m, respectively. The geochemical characterization of brines and evaporites is based on data from a titrimetric analysis and mass spectrometric analysis with inductively coupled plasma. Samples of surface and groundwater were analyzed, as well as bottom sediments of water bodies. The waters of the western reservoir belong to the type of weakly alkaline sulfate-chloride, and the waters of the eastern reservoir to the type of alkaline sulfate-chloride. The main difference in the macrocomponent composition is the enrichment of the waters of the eastern reservoir with a bicarbonate ion. Groundwater is characterized by higher salinity and, in our opinion, is the main source of useful macro and micro components in Taloe lake. The microcomponent composition is typical for the waters of mineralized lakes in the arid zone. The main microcomponents are lithium, strontium, bromine, boron, and to a lesser extent barium. The main difference is the enrichment of the waters of the eastern reservoir with boron. The geochemistry of bottom sediments (salt marshes) is completely comparable with the geochemistry of the waters of lake Taloe. The main macro and micro components are similar, but the content of the components is much higher than in the waters.
