This article presents the results of an integrated water quality assessment of Markakol lake. The adopted integrated water quality index is a mathematical tool used to transform the complex influence of large multi-parameter water quality indicators into unambiguous indices, to facilitate informing the public and legislative decision makers, to establish a common reference system of the water body. Integral assessment of water quality of Lake Markakol was carried out according to physico-chemical and toxicological parameters, which is based on already existing developments, but due to a number of objective reasons it is extremely simplified, contains limited data, was made using values of pH of water, total mineralization, total water hardness and the complex index of water pollution (CIWPhc) taking into account the hazard class, based on groups of toxic ingredients on the signs of the hazard class. The optimal parameters selected for the integral assessment, although limited, the resulting assessment for each parameter is representative. Conducted integral assessment of water quality of Markakol lake by hydrochemical and toxicological indicators shows that the water generally meets regulatory requirements and refers to class 1 (conditionally clean).
