The Elkon uranium-ore region is located in the upper reaches of the river Aldan of the Republic of Sakha (Yakutia) within the Elkon mountain range. The resource potential of the massif allows us to consider it as the largest reserve source of uranium, gold and many other minerals in Russia and the world. During the development of deposits, environmental problems arise, for example, the quality of watercourses. In this regard, it is important to study the algal flora, which are natural indicators of the qualitative state of the waters and study of the hydrochemical state of water. The results of field and laboratory hydrobiological and hydrochemical studies of the rivers of the study area are presented. For the first time, an inventory of phytoplankton and phytoperiphyton algae in the study area was carried out. It was revealed that the basis of the taxonomic spectrum of algal communities is formed by the algoflora of the Bacillariophyta division, Cyanobacteria are less diverse, Chlorophyta and Ochrophyta are single. Phytoplankton in all studied rivers is extremely poor in terms of the number of species, abundance and biomass. Hydrochemical studies have shown that the content of the majority of normalized ingredients in the studied watercourses of the river Aldan in the area of the Elkonsky horst is below the maximum permissible concentrations. There is a high content of petroleum products. In summer, a high content of sulfides in the water of the Neprokhodimyi stream, which flows into the river Kurung, is noted. This circumstance, as well as the very low levels of phytoplankton at the stations of the Propadajushij stream, are the result of many years of mining in the past years of polluted mountain dumps in the Kurung river basin. In general, it has been determined that the qualitative state of the rivers in the Aldan river basin within the Elkon uranium ore region is due to the low-temperature regime of the climate and waters, as well as the location in the area of discontinuous distribution of permafrost. The work was carried out according to the state task on the topic “Vegetation cover of the permafrost zone of the taiga Yakutia: biodiversity, habitat-forming functions, protection and rational use” (scientific topic code: FWRS-2021-0023; within the framework of the draft state task (No. FWRS-2021-0014) of the program in the priority area of the Program of Fundamental Scientific Research in the Russian Federation for the long term (2021-2030).
