Results of ichthyologic research in the Gorky and Cheboksary reservoirs upstream and downstream technological zones, as well as at the Nizhny Novgorod hydro power station facilities have been presented. The research has been carried out with the use of advanced standard ichthyologic approaches and methods. According to outcomes of larvae and baby fishes check counting in water receiving windows, technological water supply systems and the power station tail race the total number of the aquatic biological resources species passing through the systems has been stated. An experiment on determination of baby fishes’ survival rate after passing the work chambers and water transporting ducts has been conducted to estimate hydro mechanisms’ mechanical and physical impact upon lethality degree. On the basis of the data obtained the measure of natural harm to aquatic biological resources incurred by operation of power station mechanisms and technological water supply system, as well as in the process of hydroelectric units modernization has been determined. Various options of compensation measures aimed at balancing the damage incurred have been listed. Proposals on composition and application of the set of efficient protective/preventive measures to mitigate annual aquatic biological resources losses caused by the Nizhy Novgorod hydro power station hydro power units and water supply system.
