The monitoring results of the Saratov reservoir water quality for the period 2000-2018 are presented. The observations were carried out monthly at a stationary point located in the downstream of the Zhiguli hydroelectric station. It is established that the water quality in the water supply source is characterized by a significant seasonal variability. During the period of algal nuisance, the reservoir organic pollution increases, and the concentration of nutrients decreases. Excessive content of organic substances in the summer low water period complicates the technological processes of water purification. Phosphates, whch concentration drops to almost zero at the peak of water «bloom” are the limiting indicator inhibiting the algal nuisance.
