The Zuvintas Lake. located in southern Lithuania in the basin of the Dovine River is one of the biggest takes and the oldest natural reserves of the country. However, the changes in the hydrology or the Dovine River basin, caused by large-scale melioration and water management works carried out in the 20th century, have resulted in significant alteration of hydrological regime aid decrease in biodiversity of the Zuvintas Lake and Surrounding wetlands. In order to prevent the ongoing deterioration or the Lake and wetlands solutions have to be found. Therefore, various scenarios have been analysed to evaluate the impact of water management alternatives. For these scenarios the physically-based distributed parameter model SIMGRO was used. The results have shown that natural water regime in the Zuvintas Lake is hardly reversible. However, the replacement of sluice-gates implemented at the Outlet of the Zuvintas Lake by overflow weir as well as the blocking of drainage ditches and the removal of scrubs and trees in the wetlands Surrounding the Lake call be highly successful measures to improve hydrological conditions.
