RECONSTRUCTION OF NON-EXISTENT BATHYMETRY LAKES KROKOWO

Intensive land reclamation works carried out a few centuries ago in Poland contributed to a significant impoverishment of the hydrographic network. Currently, more and more often there are problems related to water deficit and implementation of a programme aimed at expansion of retention, e.g. through the construction of artificial reservoirs or damming of natural jellies. In this work, the morphometry of the non-existent Krokowo Lake was reconstructed. It was established that as a result of the anthropopressure impact, the body of water of the area 58.0 ha and capacity of 2.6 millions m3 disappeared. In the light of the increased retention capacity in Poland, the restoration of natural lakes seems to be an interesting approach. Renaturalisation of these environmental elements in the context of improving the water balance components seems more justified than the creation of new (artificial) components.
