The need for specific knowledge of the functioning and interaction of hydrological phenomena in a basin necessitates the application of monthly water models to quantify the change in storage of an area where collected data are scarce or very recent. This work was performed in the hydrologic period from 1980/1981 to 2000/2001 in the Simpson river basin (basin of the river Aysen), located in the Aysen Region, Chilean Patagonia (South Latitude 45°20'-46°10'). A parsimonious model of 6parameters, slightly modified to the characteristics of the study area, is used; for which a spatial distribution of precipitation and potential evapotranspiration is obtained with geostatistic and Hargreaves and Samani reference evapotranspiration. The result was a monthly distribution of the storage model with correlations of 0.88 and 0.83 for the calibration and validation periods, respectively, and an average annual water balance error less than 5%.
