An attempt was made to predict the amount of silting in small water reservoirs in the case of a lack of hydrological data. The current silting volume of the Cierpisz, Głuchów and Brzóza Stadnicka reservoirs was measured and a forecast was prepared using Gončarov’s method. Since the silting volume of the reservoirs for the first year of operation was not known during the computations, it was calculated as a product of sediment trap efficiency and average annual sediment transport. The trap efficiency of the reservoirs was determined from Brune’s chart and the amount of the incoming suspended load was computed using the DR-USLE method. The forecasted lifetime of the reservoir in Cierpisz is 90 years, in Głuchów – 62 years, and in Brzóza Stadnicka – 19 years.
