Anthropogenic eutrophication and ways of lake systems restoration in northern Kazakhstan

Abstract

The article is concerned with the processes of eutrophication of lake systems in Northern Kazakhstan. A
comprehensive assessment of the current state of the ecosystem of the Zhamanovskoe Lake was carried out. The main reasons
for the eutrophication of the Zhamanovskoe Lake have been identified: plowing of the catchment area, use of pesticides, cattle
grazing and watering. Activities on land reclamation were developed. The Zhamanovskoe Lake is a typical reservoir of Northern
Kazakhstan in terms of size, water receiving, origin of the lake basin, etc. Research undertaken can be applied to more water
