On the basis of generalization and analysis of long-term data, the peculiarities of the processes of pollution by nutrients of the waters of the Kuibyshev reservoir were studied and the specificity of the seasonal variability of nutrients was revealed. It was revealed that all the nutrients in the water of the Kuibyshev reservoir are characterized by seasonal variability, which is most pronounced in nitrate ions. The results of the study show that in 2009-2015 yrs perennial average monthly concentrations of nutrients did not exceed the fishery standards in the water of the Kuibyshev reservoir.
