ABSTRACT
The aim of this study was to assess a trophic state of reservoirs in southern Poland under diversified human impact with different morphological, hydrological and river basin features. Three reservoirs were studied: Wapienica, Goczałkowice and Łąka. To estimate a trophic state of reservoir waters criteria based on measured total nitrogen, total phosphorous and chlorophyll a concentrations and limiting values of trophies differentiation as well as the Carlson trophic index (TSI) were used. Relationship between river basin operation use and a trophic state of reservoir waters was found. A trophic state described by TSI indices and concentration criteria for the Wapienica reservoir water were encountered between oligothropy and mesotrophy. For the Goczałkowice reservoir the trophic state was described between mesoeutrophy and eutrophy and for the Łąka reservoir it had both eutrophic and hypertrophic features.
