The article is devoted to the study of intra-annual distribution of runoff in the southern and South-Eastern part of Bashkiria and center of Orenburg government, on the example of a river basin the Ural. For rivers of the area calculated norms, coefficients of variation and average standard deviation of monthly, seasonal, annual, maximum and minimum flow, and the tendencies of its changes. The calculated ratio of average and maximum water discharge spring high water, the ratio of the maximum and minimum monthly and annual discharges, the calculated annual runoff layer. Using the method of wavelet transform in the data flow of the rivers of the study area identified a cyclical pattern of water availability. Moreover, it revealed the narrowness of correlation between average monthly expenditure of each month and annual average water consumption, as well as between the average monthly water costs. Determined the statistical significance of the detected correlations.
