Abstract: The object of present study was Sukiel Lake (area 20.8 ha, max. depth 25 m), localised in north-eastern Poland (Mazurian Lake District), in Olsztyn city. The aim of this study was to analyse the phosphorus fractions in the sediments of two lake bottom zones - profundal (25 m) and sublittoral (7 m). Observed high P concentrations in the deposits of Sukiel Lake and quantitative domination of hard mobile P fractions (NaOH-TP, HCl-P and res-P) suggest that the sediments of Sukiel Lake are the effective trap for phosphorus and that limits excessive internal loading in this lake.
