 note = {A large silver deposit Mangazeyskoe at the headwaters of the Yana River basin in North-East Yakutia has a considerable impact on vulnerable ecosystems of Alpine tundra. In the case of inadequate environmental protection measures, adverse environmental consequences may occur. The particular interest is the hydrobiological status of the rivers affected by the mining production waste water. In this regard, quantitative and qualitative baselines for water pollution indicators were studied. For the first time, preliminary data on the species composition of algae in the phytoplankton, phytoperiphyton, and zoobenthos of the watercourses at the Mangazeyskoe deposit. In the algal flora of reservoirs in the area of the Mangazeyskoe deposit, 230 identified species have been as represented by 260 intraspecific taxa, including those represented by a nomenclature type from 8 divisions. In the zoobenthos of the area under study, 28 species and forms belonging to three types have been found: annelids, arthropods and mollusks. It has been determined that the main part of the species of zoobenthos belongs to amphibiotic insects, which accounts for more than 70%. It has been noted that the current studied background condition of algae and zoobenthos in the area of the deposit consists mainly of cryophilic species.},
