Studies in surface runoff formation reveal the significance of its formation conditions. They show also that temporal dynamism of occurring changes increases pro rata to spatial changes. The prevailing impact of anthropogenic factor on environment formation becomes more evident recently. The creation of the large engineering and technical facility - Kuibyshev reservoir - significantly affected the surface runoff formation at the new basin territory. Shallow and drying out watercourses prevail among the flat rivers of the acclivitous slope in Volga river valley at Western Zakamia of Tatarstan Republic. Their hydrological network structure has changed drastically during Kuibyshev reservoir existence. A comparative analysis of the rivers water low flow rates showed a significant increase in water content.
