Outcomes of the Lake Krivoye main algal characteristic studies have been presented. The lake is located in Novosibirsk Oblast Karasuk Rayon and relates to the Karasuk River cultural landscape. There are very few easily accesible materials concerning the lake status, and the most of tham are dated back to the middle of the past century. Therefore, the lake contemporary ecological status is of special interest. Within the framework ofthis study the phytoplankton species composition and its seasonal succession have been investigated. Analysis of the qualitative development (abundance, biomass, etc.) has been performed, the role of the main algae divisions in its formation has been considered. In the process of studying sets of the main predominate species for each stage of selection has been found and the species diversity and community uniformity indices have been analysed. Such a significant indicator of the hydrocoles community morpho/functional structure as dimesional cell characteristics has been discussed. The pollution level has been assessed on the basis of the saprogenic/biological analysis data and the water quality class gas been determined.
