“…Comparable findings to those reported in this study (e.g., due to climatic conditions and the scale of anthropopressure) were given in earlier studies concerning lakes in Poland, conducted in various periods and for a varied numbers of water bodies. They may be referred both to changes in area [26][27][28][29][30] and bathymetry [31][32][33][34][35]. In both cases they are consistent and thus they confirm that we are observing successive reductions of lake area and depletion of water resources.…”

“…According to Lossow [63], the primary causes of the acceleration of lake evolution in the Mazurskie Lakeland (east Poland) include changes in the land use in agricultural catchments, excessive tourist pressure, urbanisation, and the resulting sewage supply. An increase in the eutrophication and improperly conducted melioration are among the main causes of drastic changes in the surface area of Lake Udzierz and Lake M ątasek, which shrank by 53.3% and 97.9%, respectively, over the century [64]. Clear regulations regarding the supply of nutrients to surface waters were introduced at the moment of Poland's accession to the European Union, but in addition to the external supply, the issue of the accumulation of such compounds in lake sediments remains unsolved [65].…”

Lakes are an important element of the hydrosphere that contribute to the stabilisation of water circulation by providing biodiversity conditions or supporting the development of different branches of the economy. All these properties depend on the longevity of lakes in the environment and the processes related to their evolution. Based on archival morphometric data from historical maps and modern cartographic studies, this paper presents an analysis of changes in their surface area over a period of 100 years. Among 169 lakes, a decrease in surface area was recorded in 156 cases (including the complete disappearance of two lakes); no change was observed in four lakes; and seven lakes increased their surface area. The total surface area of all the lakes has decreased by 11.4% in comparison with the initial state in the early 20th century. The highest rate of decline concerned the shallowest lakes with a maximum depth of up to 5.0 m and lakes with the smallest surface area of up to 20 ha, averaging 24.1% and 22.2%, respectively. The spatial distribution of changes in the surface area of lakes is variable, and at a larger scale it presents no similarities. This suggests that factors determining the rate and direction of changes in the surface area of lakes depend on their individual features and local conditions, which is in accordance with similar studies from the territory of Poland. The obtained results reveal the scale of the changes in the surface area of the lakes, potentially providing important information for authorities in charge of water management in the context of activities aimed at slowing down the disappearance of these valuable ecosystems.

“…As they evolve, however, a vast majority of lakes are subject to successive disappearance. According to the current research in the scope, this process is usually associated with changes in the surface area [9][10][11], whereas the lake basin as a three-dimensional concave landform is also subject to the process of accumulation (filling) of sediment, consequently leading to the disappearance of a lake. The disproportion between the analysis of changes in the surface area of lakes and their complex disappearance (identified as a reduction in water resources) is determined by insufficient comparative data, namely, bathymetric maps from two or more periods [12].…”

The historical effects of land development on water management currently require a new approach, in many cases involving attempts at the restoration of the quasi-natural state. This is evident in reference to many regions in Poland, where the hydrographic network has been diminishing over the centuries, among others in favour of obtaining new agricultural land. Such activities overlap with natural processes causing transformations of the hydrosphere. The most serious problems currently include water deficits resulting from climate change and human activity. This paper employed archival bathymetric maps from the beginning of the 20th century for the determination of the scale of changes in the morphometric parameters of six lakes in western Poland. It was determined that over a period of more than a hundred years, the surface area (12.2%) and original volume of water bodies (13.9%) were largely reduced. This situation was caused by both natural (overgrowing and shallowing) and anthropogenic (change in water level) factors. The obtained information points to the need of an inventory of historical bathymetric maps of lakes. In combination with modern research, this will allow for the determination of changes in the water resources of lakes and, in a longer-term perspective, potential possibilities of their renaturisation. This knowledge is important in the context of the reconstruction of water resources in the territory of Poland, where their deficits are recorded increasingly frequently. It should also be emphasised that the restoration of the natural capacity of water retention in lakes is a more economical solution and, most importantly, it is not invasive for the environment.
