A dependence of physicochemical indices of lakes on urbanized territories on their morphometric parameters has been determined through factorial analysis using the method of main components by considering an example of water bodies of the city of Kazan. Hydrophysical indices are influenced by the volume of water mass, and by the index of openness, while hydrochemical indices are influenced by the mean width, and by the specific water catchment. The study revealed also the reciprocal influence of hydrochemical and hydrophysical indices of the lakes (between oxygen and the pH value, oxygen and water transparency, oxygen and mineral phosphorus in the water, and between phosphorus and BOD5).
