Abstract Grouping analysis offers a fresh approach to monitoring the quality of inland water bodies. In this study it has been applied to certain parameters from a network of stations on lake deeps. General trends were sought by examining the distribution of the means for 1971–1977 among five classes created by grouping the means for 1965–1970. Marked changes in water quality are seen to have taken place, mainly in lakes whose condition was almost natural (loss of purity). These changes are indicated by differences in the distributions of the values for conductivity, alkalinity, total nitrogen and oxygen. The results suggest an increase in the importance of loading from non-point sources.
