Our results of daily monitoring of the water temperature, hydrochemical parameters, as well as the zooplankton composition and structure in the protected overgrown and non-overgrown littoral of Berd’s Bay of the Novosibirsk reservoir are presented. The data obtained allow us to reveal differences in the daily dynamics of the water temperature, hydrochemical and hydrobiological characteristics of littoral areas of different types. Features of the horizontal migrations of zooplankton are determined by the water overgrowing degree.
