The algoflora of the surveyed areas is characterized, and the dominant species are identified. The annotated list of cyanobacteria and algae includes 309 species (including varieties and forms - 330 taxa) from 9 divisions and 140 genera. The diatoms were the most numerous and diverse - 178 species (including varieties and forms - 197). Among the most interesting and rare species with a limited distribution are cyanobacteria Nostochopsis lobatus , diatoms Tetracyclus glans , Gomphonema pseudoaugur . For the first time, 38 species were found for the flora of the Amur region, five species were found for the first time in the Far East, the genus Nostochopsis is indicated for the first time for the territory of the Russian Federation.
