Water budget of the Zdworskie Lake in 2008–2012 period
Journal Title: Annals of Warsaw University of Life Sciences – SGGW. Land Reclamation - Year 2013, Vol 45, Issue 1
Abstract
The paper presents the results of water balance calculations for the Zdworskie Lake, Poland, based on meteorological and hydrological data of 2008–2012 period. Meteorological data have come from automatic measurement station located near Łąck in a distance of about 7.5 kilometer from geometric center of the Zdworskie Lake. The station is a part of the monitoring system of The State Forests National Forest Holding. Hydrological data has been collected from fi ve water-gauging stations located in the Wielka Struga River catchment to which belongs the Zdworskie Lake. The water-gauging stations has been established by Department of Water Engineering of Warsaw University of Life Sciences – SGGW within monitoring net constructed as a part of the Restoration Programme of the Lakes in the Łąck Commune, Płock district. Water bal- ance calculations revealed that throughout the analyzed period the retained water amount in Zd- worskie Lake should be much larger than it was actually observed. Groundwater level fl uctuations observed in one of the water-gauge sections together with geological conditions in the immediate lake catchment area suggest periodic outflow of the lake water into the ground. In the years 2008–2012 the annual loss of lake water caused by the groundwater alimentation varied ranging from about 761,000 to 2,078,000 m3.
