Small water reservoirs play many important natural, hydrological and economical functions in the agricultural landscape. They are subjected to very strong anthropogenic pressure, leading to their quantita-tive and qualitative degradation. A classification proposal for small water reservoirs in an agriculturals from a deterioration point of view is presented in this paper. Classification is based on analysis of the following phenomena and processes: drainage, sewage drops, landfills, cattle pasturage, fish farming, fishing, tress and shrubs cut out as well as bordering on urban areas, country roads, landfill sites or cultivated fields. Four classes of anthropogenic impact were distinguished. Reservoirs free from any anthropogenic impact constitute the first class.
