Abstract:

Hydrologic division of the Great Masurian Lakes (North-eastern Poland) into the northern and southern drainage basin was found to be reflected in different trophic status of lakes. Chlorophyll (but not nutrient) concentrations in the northern part of the system were significantly lower than those in lakes of the southern part. It has been shown that tunnel-valley lakes (numerous in the southern watershed) appear to be more eutrophied in terms of chlorophyll abundance than morainic stratified lakes. Hypolimnetic enrichment and internal loading were probably responsible for the lack of in-lake phosphorus and chlorophyll decline in spite of the evident decrease of the external nutrient loading which had taken place between 1985 and 1996. Such a positive response was observed, however,in the case of nitrogen. Only in a hypertrophic Lake Niegocin some symptoms of recovery were noted after reduction of external point source pollution.
