A forecast about the process of silting was prepared for two small reservoirs – Brzóza Stadnicka (the higher one) and Brzóza Królewska (the lower one) – located on the same, hydrologically uncontrolled, stream Tarlaka. An analysis of the silting of the lower reservoir was performed taking into consideration the trap efficiency of the higher reservoir. The amount of the incoming sediment was calculated using the DR-USLE method. The trap efficiency was determined using Brune’s method, which allowed the use of Gončarov’s method in the next step. The forecast suggests that the life time of the Brzóza Królewska reservoir may be prolonged from 77 up to 124 years.
