Abstract

The paper refers to the contemporary sensitivity of a ribbon flow-through lake to changeable meteorologicalconditions (precipitation, evaporation). We checked whether the lake morphology can affect the abruptchanges in hydrological conditions under which environmental changes occur. We analyzed changes in thelevel and extent of the water table in relation to morphological thresholds of a Charzykowskie Lake. Changesin the lake water level were disproportionate in relation to small changes in the volume of water involved in theexchange. During 55 years of observations, the lake water level did not exceed the threshold values of sensitivityto shortage or surplus stress.

Keywords: climate change, flow-through lake, Charzykowskie Lake, lake morphometry, lake sensitivity, natural resources management, physical limnology
