Surface area of this reservoir is 570 ha. Maximal depth is 10 m, total volume 20 mln m3• In results self-purification processes water in the ecosystem is in I and II quality class. In the saprobity clasassification it is in betamezosaprobic class. Low number of macrobenthos organisms is the result of the Czarna Przemsza river pollution. In the I Part of this paper results of hydrochemical investigation was given.}, type={Artykuł}, title={The Hydrobiological Researches of Przeczyce Dam-Reservoir (Czarna Przemsza River). Part II.
