This paper intends to know the fundamental surface hydrological characteristics of the system formed by the Upper and Upper-Middle Sub-basins in the Sauce Chico river up to the limnigraphic station HL6005 (Nueva Roma - National Route 35). The river is developed on a total area of 1573 km 2 with a main collector of 104.5 km length which rises in the Sierras Australes in the province of Buenos Aires. The complex situation of irrigated agriculture in different tranches of the valley, creates the need for a preliminary assessment of the potential of integral and sustainable use of soil and water resources for the study area. Instantaneous daily fluviometric data available is analyzed and the zonal rainfall, evapotranspiration and the potential for monthly, annual and event runoff are examined. An hydrological modeling program that provides outflow hydrographs of each sub-basin, peak flows, peak times and volumes of runoff from an individual storm event is applied. From the point of view of supply for irrigation, the duration of average monthly flows for percentages of probability of occurrence of 90, 50 and 10%, determined average flow of 0.51, 1.63 and 3.98 m 3 /s, respectively.
