State and Development of Phyto- and Zooplankton in Lower Reach of the Angara River: Prognosis for Forming Plankton in Boguchanskoe Reservoir

Abstract

Long-term data (1997-2007) on phyto- and zooplankton from the near-dam area of the head water of the Ust-Ilimskoye Reservoir and the Lower Angara River have been presented in this paper. Species composition, development and spatial distribution of plankton, as well as water quality have been analyzed in the area of the river bed of the future Boguchanskoye Reservoir. The prognosis of qualitative and quantitative characteristics of phyto- and zooplankton and stages of plankton formation after the damming of the Angara River by the Boguchanskaya Power Station has been made on the basis of the data obtained for the Ust-Ilimskoye Reservoir.
