This study aimed to analyze the available amount of water in the Dragaçina River to meet the different water needs in the Municipality of Suhareka. The water problems in this city are more pronounced, especially in the vegetation period of July–September, where the area is significantly affected by drought. The Dragacina River carries about 10 hm³ of water per year, and affected neither by urbanism nor massive deforestation of the basin. However, there are no multi-year measurements of inflows for this river, whether they are average, maximum or minimum ones. Therefore, the study is based on several multi-annual monthly rainfall measurements and some characteristics of the Dragaçina River Basin. Knowing the average annual flow coefficient η = P_eff / P_bruto it is possible to convert these precipitations to P_eff [mm] flow and then to monthly flow. The inputs for other years from 1983/84 onwards are obtained by simulating time series. Then, for such inflows, the probability distribution functions of small waters are assigned and the usable volume balance is carried out. Assuming an average annual withdrawal from the reservoir QA_min^mes. = 0.63 × Q_mes. which should be constant throughout the years, then the length of the critical period will be 0.13 years or approximately 48 days, for P_H = 95%. Starting from the initial acquired volume of 1 hm³ it is possible to achieve 95% < P_H < 99%. Therefore, it follows from this analysis that this river can provide a significant amount of water for the needs of the Municipality of Suhareka.
