Abstract: An attempt was made to evaluate the process of lake disappearance over the years 1886-2019 in the Łęczna-Włodawa Lake District. The analysis were based on archival cartographic materials (WIG maps published in 1936 and maps in the PUWG 1965 system) and on vector map based on BDOT10k. It was determined that over a period of 133 years, the surface area of selected natural water reservoirs was reduced by 10,26%. Changes have been influenced by many factors: the building of the Wieprz-Krzna canal and the drainage system connected with it, agricultural land use, rapid development of tourism and coal mining. Results presented in this paper show that the greatest risk of decreasing of lake area concerns reservoirs of small size (<50 ha) due to their more limited ability to self-purificate and lower resistance to degradation. A greater change was observed in the case of lakes located in the Poleski National Park and its buffer zone (-16,51%) than in the case of other studied water reservoirs (-8,91%).
Key words: lake disappearance, lake area, Łęczna-Włodawa Lake District, Wieprz-Krzna canal
