On the basis of data for 29 small stream lakeside watersheds examined in August, spatial diversity of chemical composition of fluvial waters supplying the lakes of Suwałki Landscape Park (north-eastern Poland) has been studied. Differences in chemical composition of waters (consistent for lake waters and the supplying ones) were shown in connection with watersheds of three principal river systems in the Park, i.e. the Szelmentka, Czarna Hańcza, and Szeszupa. The monthly values of areal surface runoff (kg · ha-1) of phosphorus and nitrogen for summer was estimated and compared with data for Masurian lake watersheds. There was a negative correlation between the flow of streams and phosphorus concentration at the outlet to the lake. Differences in concentrations of some elements significant for phosphorus transformations (Ca, tot-Fe), in phosphorus content in seston and in a dissolved form between fluvial and lake waters were found. This allows to assume that sorption of dissolved phosphorus in lakes is fast (e.g., precipitation in the form of calcium phosphates) and followed by transport to deeper waters on sedimentating seston particles (probably mostly mineral ones).
