We studied the species diversity and quantitative distribution of benthic organisms of the Chirkey and Miatlinsky reservoirs. During our research, the benthic communities of the Chirkey and Miatlinsky reservoirs were represented by a small number of species, which were mainly found in places, where soft silt was deposited. It was established that in the Chirkey and Miatlinsky reservoirs, argylophilic and psammopelophilic biocenoses are developed, which include single specimens of Crustacea (Gammaridae, Mysidacea), Gastropoda, Oligochaeta and, mainly, insect larvae and other secondary aquatic organisms - Chironomidae, Оdonata, Ephemeroptera, Coleoptera, Plecoptera, Tipulidae. It was noted that the species diversity of bottom organisms of the Miatlinsky reservoir was slightly richer compared to the Chirkey reservoir. It was noted, that the benthos biomass was distributed unevenly depending on the nature of the soils: the highest biomass values were associated with soils with autochthonous silt located at great depths, while in areas with a pebble bottom and allochthonous sediments in the coastal zone, its biomass was noticeably reduced. In general, the benthos of the studied reservoirs is poorly developed and its production capabilities as a food base for fish are small.
