This paper presents a statistical correlation procedure to predict a master depletion curve by use of basin characteristics and the specific storage of water available for runoff at a particular recession discharge in small watersheds. Percentual lake area, drainage density and a weighted lake inflow area index are the most significant parameters to explain differences in specific storage among basins. The significance shows time-dependency. Percentual lake area has a decreasing contribution to a total explanation from high to low specific discharges, while drainage density increases its importance.
