Abstract:

Annual total-P input (TP) to 20 lakes of Suwałki Landscape Park (SLP) with a fluvial inflow, surface runoff and precipitation has been estimated. In most cases, the annual TP input is lower than the dangerous one ace. to Vollenweider's (1976) criteria, whereas the weight ratio TN:TP points to stimulation of the phosphorus deficit. A relatively high correlation has been found between the annual load expressed in TP per lake surface unit and TP concentration in surface layers in summer. TP concentration in surface layers does not determine the variation of water transparency (SD) and chlorophyll a concentration with sufficient accuracy, whereas the relation between the latter two trophic parameters and algal biomass is high. For the majority of lakes, and practically for all mesotrophic and deep lakes, regressions of SD or TP vs. chlorophyll found for different groups of Masurian lakes, do not apply. The values of these parameters are much lower than they should be according to these models at relevant TP concentration. A conclusion has been drawn about the low bioavailability of TP supplied and present in SLP lakes, and thus the slower eutrophication rate of SLP lakes. This conclusion is convergent with results of previous investigations (Hillbricht-Ilkowska 1990).
