AbstractThe aim of the paper was determining, on the basis of physicochemical indices, the ecological state and usable values of water inflowing into and flowing away from a small water reservoir, and establishing its effect on the surface quality waters.The research was conducted in the „Nowy Zalew” rese rvoir in two measurement points situated on the water inflow to and outflow from the reservoir. Water samples were collected at monthly intervals from March to November, 2011. Mean values of 9 indices (the temperature, pH, SO42-,Cl-, Mg2+, H-NH4+, Mn2+, Na+ and K+) were almost the same, four (total suspended solids, electrolytic conductivity, dissolved solids and Ca2+) were slightly lower, whereas for N-NO3-, NO3-, Fe2+/3+ and P total clearly lower on the outflow. Moreover, aerobic conditions were more favour able on the outflow. Water in both measurement points revealed good ecological state (class II), however on the outflow this purity class was influenced by N-NO3- concentrations, whereas on the inflow also by oxygen concentrations. The inflow and outflow waters satisfied the requirements for waters in bathing resorts and those which are the natural habitat of cyprinid fish. Summing up, it may be stated that the water on the outflow reveals better physicochemical parameters than on the inflow, therefore owing to diverse processes occurring in it, the analyzed reservoir has been functioning as a biofilter, which advantageously affects the quality and usable values of surface waters.
