Sensitivity of a large flow-through lake to meteorological condition and anthropogenic stress (hydromorphological assessment)

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