Modern state of a phytoplankton and microphytobenthos of boreal reservoirs of Krasnoyarsk region

The algas of boreal reservoirs posed in district Vankorck of a petroleum deposit, guessed boreal path of an oil pipeline and sea of the terminal, represented 231 species and specific taxon from 7 division (phytoplankton - 149 species from 7 division; microphytobenthos - 138 species from 5 division). Values of a biomass of a phytoplankton in Yenisei - 0.59±0.07, in reservoirs of left bank - 0.23±0.04 and in reservoirs of right bank - 0.11±0.02 mg/l.; microphytobenthos in reservoirs of right bank - 30±5, Yenisei - 10±7 and in reservoirs of left bank - 9±3 mg/10 cm2. The evaluation of water quality in terms of saprobicity indexe of a phytoplankton (2.06±0.07) and microphytobenthos (1.76±0.08) determine water of reservoirs by 3 class of quality, satisfactory cleanness, b- mezosaprobicity of zone. The category trophic of water on a biomass of a phytoplankton (0.25±0.04 mg/l) corresponds mezotrophic by the class of polar series; biomass of a phytoplankton of lower Yenisei river (0.59±0.07 mg/l) - evtrophic by the class of polar series; biomass of a microphytobenthos (15±5 mg/10 cm2) - polytrophic the class of polar series.
