The progress of civilisations causes changes in the water catchment areas lakes. aquatic waters are order - phosphorus and nitrogen compounds. Level of activity alkaline phosphatase (APA) has an important impact on the chemical and biological processes taking place in the aquatic environment. APA belongs to a group of indicators, who tells us about the extent limitations to development of biomass in the tank water. To estimate differentiation of activity of total alkaline phosphatase in water of the Strazym Lake, in time July - September of 2009. Studies upon water revealed that, among the zones analyzed, upper sublitoral layer was characterized by the highest phosphatase activity. From the analysis of seasonal oscillations it follows that activity maximum for alkaline phosphatase, both in water, occurred in July 2009. Overall activity in alkaline phosphatase in water considered lake fluctuated seasonal throughout the period test bed.
