The article deals with the study of intra-annual discharge distribution of the Ural River basin runoff. Norms, coefficients of variation, and average standard deviations of monthly, seasonal and annual runoff, as well as maximum and minimum flow and the tendencies of its changes, were determined for rivers in the area. The average and maximum water discharge spring high water and the ratio of maximum and minimum monthly and the annual runoff were calculated. Based on the wavelet transform method applied to the river flow data of the area under study, a cyclical pattern of water availability was identified. Moreover, the closeness of the correlation between average monthly expenditures and annual average water consumption, as well as the average monthly water costs was revealed. The statistical significance of the detected correlations was defined.
