 abstract={In result of a lew years' investigations or silting of small water reservoirs located in South Poland, intensity ofthe silting process as well as the granulometrie and chemical composition ofbottorn sediments were evaluated. The content of heavy metals i.e. copper, lead and cadmium was determined in samples collected in various parts or five small water reservoirs. The content of heavy metals was appraised according to the regulation of the Minister of Environment, according to the criteria or Polish Geological Institute, of Inspection lor Environmental Protection, of Institute of Soil Science and Plant Cultivation, and according to the Muller's method. The obtained results or determination of the examined heavy metals concentrations were compared with the values or reservoir and river sediment concentrations determined by other authors in Europe. Appraisal or sill quality, respectively to the adopted criteria, showed only an insignificant degree of pollution. Concentrations ofmicroclemcnts do not exceed the toxic concentrations for soils and environment bul may have a harmful influence on living organisms. Recording of changes or heavy metal pollution during many years' operation or small water reservoirs, considering changes occurring in the basins, requires continuation of investigations. It will enable to record changes or pollution during a longer period or operation or reservoirs, also against the background 01· changes occurring in river basins.},
