The paper presents the water classification of four small retention reservoirs on the basis of selected physical and chemical indicators, such as: conductivity, pH level, dissolved oxygen, calcium hardness, general hardness and alkalinity. Three reservoirs (Ożanna, Kamionka and Cierpisz) are within the limits in terms of average values for the second class of water quality. Water in the Nowa Wieś reservoir does not qualify as second quality class of surface water. These reservoirs have had very irregular seasonal variations of water quality. Unambiguous correlations have not been established. Aggressive properties of water have been tested on the basis of Langelier (IL) or Ryznar (IR) indexes and calcium carbonate saturation [pHs]. Waters in the Ożanna and Nowa Wieś reservoirs do not have aggressive properties. Both the Kamionka and Cierpisz reservoirs are characterized by corrosive and leaching aggressiveness.
