An attempt at a typology of karst lakes in the Połaniec Basin (Małopolska Upland)

In the belt of the Polish Uplands, including the Holy Cross Region, lakes occur sporadically. In some places, however, they are somewhat more abundant. They are usually objects with a small surface area. The majority of them have not been subject to thorough investigation. Therefore, the objective of the paper is the expansion of knowledge regarding these lakes. The paper among others presents the characteristics of several lakes with aeolian genesis located on the Przedbórz Upland in the catchment area of the Wierna River and in the Nida Basin near the towns of Busko-Zdrój and Pińczów. The study results determine the morphometric parameters of the lakes, also pointing to an exceptionally high variability of physical and chemical water properties, as well as the possibility of periodical disappearance of the lakes. Moreover, the study results provide a necessary and solid basis for further investigation of the lakes, which in the context of the observed increasingly serious water deficit and decrease in the level of surface waters and groundwaters is undoubtedly of high importance.

“…Another, more abundant group of lakes in the Holy Cross Region includes lakes with karst genesis. They are located in the northern part of the Nida Basin (Zieliński 2013;Stachura et al 2018).…”

“…Duży Staw, with the three other lakes mentioned above. constitute one hydrological system with an area of around 5 ha (Zieliński 2013;Stachura et al 2018). In turn, the lakes of Łajba and Donica are small with areas less than 1 ha and separated from water cycling in karstic sediments (Zieliński 2010a).…”

Chemistry of Bottom Sediments from Selected Karst Lakes in the Vicinity of Staszów (Nida Basin)

The aim of this study was to reveal the chemical composition of bottom sediments in karst lakes located in the northern part of Połaniec Basin (eastern part of the Nida Basin, vicinity of Staszów municipality). A field investigation was carried out in 2010 on four lakes: Duży Staw, Donica, Dziki Staw and Łajba. The contents of a very wide range of chemical elements were determined, which is a rarity. On the basis of our research, it was found that the analysed lakes differed considerably between each other in spite of their close location. In general, sediments contained fair amounts of organic substances as well as Fe, Al, Ca and Mg due to the type of source rock and soligenic lake water supply. Increased concentrations of V, Cr and Ni might be explained by the weathering of rock material. In turn, higher contents of Zn, Pb, Cu and Co in the bottom sediments from Duży Staw indicated anthropopression. The measurement results obtained in this study will allow a future comparative analysis with bottom sediments from other lakes.

“…Lakes located south of the range of the Baltic glaciation, particularly those with a surface area of more than 1 ha, show sporadic occurrence (Choiński 1995). Nonetheless, in the Holy Cross region that for simplicity was herein treated as the equivalent of the Świętokrzystkie Voivodeship (Holy Cross Voivodeship), such lakes can occur more frequently (Zieliński 2010(Zieliński , 2013Stachura et al 2018). Lakes with various genesis are encountered here (aeolian, karst, and fluvial).…”

Transformation of the morphometry of Lake Osieckie – largest lake in the Holy Cross region

2021

Self Cite

The paper presents the analysis of the transformation of Lake Osieckie, the largest lake in the Holy Cross region until 2016. It is a valley lake that according to cartographic materials had undergone no changes in the shoreline since ca. 1938. The nearby activity of a sulphur mine required building three dikes on the lake, dividing it into four independent water bodies. The paper presents the analysis of their morphometric properties in comparison to those of the original lake. Although the basins of the new lakes are of natural origin, the currently existing four lakes can be described as quasi-natural.
