Changes in capacity of water reservoir Cedzyna during its exploitation since 1972 till 2003 are presented in the paper. Analyses were based on cross sections of the reservoir's basin from before its fulfillment (1967) and those measured with the echo sounder Ceeducer in 2003. Silting of reservoir was predicted based on empirical methods. The volume of reservoir was found to decrease by 112.8 thousand m³ during 31 years of its exploitation and reservoir's life span was assessed at 685 years. An error analysis was additionally made of calculating the surface area of a cross section at varying number of sounding sites. It was found that there was no need to note too many coordinates and depths and for the Cedzyna reservoir the distance between measurement sites up to 16 m was sufficient.
