Every component of the river-lake system is characterized by a complex biological community interaction among among animals, plants, and microorganisms, as well as the abiotic determinants of a habitat in which they live. If one part of the ecosystem is disturbed, it affects other parts. Lake health assessment can advance our understanding of the health status of lakes and contribute to strengthening the protection and management of lakes. The key to evaluate the health status of several lakes linked with one watercourse and differed by trophic state requires selection of the most appropriate evaluation method. We studied
