Abstract: Kraśnicki reservoir is a small (390 ha), shallow (mean depth 2.5 m) water body where as soon as 2 years after filling up cyanobacterial blooms had been observed. Research of basic limnological parameters had been taken in 2008 - 2009 to identify the scale and causes of water quality deterioration. Trophic State Index of the reservoir ranged from 74.4 to 75.5, and estimated phosphorus load from the inflow (Wyżnica River) ranged from 4.50 up to 5.87 g P m-2 year-1 which indicates that ecosystem deterioration could be induced by overfertilisation. Reservoir catchment, with arable land exceeding 70%, proved to be a potentially important source of nutrient supply both for the river and the reservoir. Also point-sources of nutrients has been identified: it is shown, that huge amounts of P was delivered to Wyżnica River from wastewater treatment plant, relieving water from dairy factory.
