The attempt of evaluation of chosen lakes from Łęczna-Włodawa Lakeland using E. Bajkiewicz-Grabowska method

E. Bajkiewicz-Grabowska method, basing on evaluation both the drainage area as matter supplier and lake resistance to degradation, has been used to assess five differing lakes from Łęczna-Włodawa Lakeland. The Krasne Lake and the Rogoźno Lake have been classified as first type – parameters of lakes and their drainage areas are not favourable for degradation. The second type – lake is resistant with the catchment having great ability to supply the reservoir with matter – was not represented by any of the selected lakes. The Rotcze Lake has been ranked as the third type – lake is not resistant but the drainage area is not active as matter supplier – pace of eutrophication is moderate but any interference in drainage area condition can lead to an increase in its rate. Two lakes Kleszczów and Miejskie have been classified as the forth type – lakes show great dependence on external factors and the catchment has a great ability to supply the reservoir with matter – the eutrophication is fast.The method can then be applied to asses lakes and their basins independently from their genesis, water trophy, water characteristics, lake and basin morphometry and catchment land use structure, geology or geographical location.
