Popis: Increase of water treatment efficiency in water supply systems during the spring period directly depends on the forecast accuracy related to mass blossoming of phytoplankton in drinking reservoirs. Object of research is the Uchinsky reservoir – the drinking reservoir having insignificant its own water collection area, and fed by water of Moscow Canal. The data on seasonal phytoplankton dynamics received in Akulovsky Hydrosite Laboratory of the MCUE "Mosvodokanal" for two stations: Pestovo (reservoir’s headwater) and Listvyanka (reservoir’s lower part), and also actinometric data of continuous supervision from 1998 to 2003 performed by Lomonosov Moscow State University’s Geographical faculty Meteorological Observatory (MOMGU) have been used in this work. Results of mathematical modeling for dependence of start date and peak values of phytoplankton’s spring blossoming in the Uchinsky reservoir depending on intensity of total solar radiation during the period preceding the phytoplankton blossoming have been presented. It has been established that the more solar energy streams’ values in the range of photosynthetic active radiation (PhAR) will be received by the reservoir surface in the middle of February, the later peaks of phytoplankton’s spring blossoming will be observed. Research results represent undoubted interest for the analysis of reservoir’s light factor influence on phytoplankton’s seasonal dynamics, and also for the exact forecast related to beginning of phytoplankton’s spring blossoming in drinking reservoirs when planning water treatment actions.
