The relationships between Secchi disc, chlorophyll, total phosphorus and total nitrogen were analysed basing on data from 25 sites in 21 Great Mazurian Lakes collected during 12 years. The best fit for the data were reached when picewise linear regression was used to approximate the relationship between chlorophyll and nutrient concentrations. The regression line divided the whole data set into two regions: lower, mesotrophic (chlorophyll to n and p was insignificant and higher, eutrophic
