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).

The Basin of the Vilyui river is located on the territory of Western Yakutia, one of the most developed and industrialized parts of Yakutia, which is of great economic and strategic importance for Russia. The region is the center of the diamond mining industry of the Russian Federation, where primary and alluvial diamond deposits are developed, a cascade of hydroelectric power stations is located on the river Vilyui. This causes environmental and social problems, negatively affecting all components of the natural environment. It is necessary to study the stability of northern landscapes to technogenic impact and study the hydrobiological state of aquatic ecosystems, in particular, the state of the algoflora of watercourses. As a result of studying the degree of stability of landscapes in the basin of the river Vilyui to technogenic impact on permafrost and bioclimatic indicators, the degree of their resistance is determined. It was revealed that, according to the permafrost characteristics, the northern taiga open forest and haze landscapes are defined as predominantly weakly resistant, the middle taiga as medium resistant. The most unstable in terms of bioclimatic indicators were mountain-tundra landscapes, characterized by the coldest and most humid conditions. As a result of studies of the current hydrobiological state of the rivers in the basin of the river Vilyui determined the low development of phytoplankton and phytoperiphyton in the river Irelyakh, M. Botuobuya and in the upper reaches of the river Vilyui, consisting of a monotonous species composition of diatoms and green algae. The maximum average number of algae varies from 82290 cells/l to 20700 cells/l, the highest biomass was noted in one area and is 1.58 mg/l. The Shannon-Weaver biodiversity index varies by sampling points along the river. Vilyuy from 0.19 bits / copy. and 1.00 bits/copy. up to 2.40 bits/copy. According to the sanitary-biological characteristics, mass species-indicators of water saprobicity were identified, which indicates the III class of water purity, as moderately polluted. Thus, it was determined that the state of phytoplankton and phytoperiphyton is under the influence of the technogenic load of diamond mining and hydropower enterprises.The work was carried out according to the state assignment 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; draft state task (No. FWRS-2021-0014) of the program in the priority area of the PFNI RF for the long-term period (2021-2030).
