Lake Dubrava (Croatian: Dubravsko jezero) is a reservoir on the Drava in northern Croatia. It is administratively divided between Međimurje County and Varaždin County and is bordered by the municipalities of Prelog, Sveti Đurđ, and Veliki Bukovec. The Drava flows into the reservoir near the town of Prelog, while the dam is located near the village of Sveta Marija.
It is the largest of four reservoirs built on the Drava, the other three being Lake Ptuj in Slovenia, Lake Ormož on the Croatian-Slovenian border, and Lake Varaždin. Lakes Ormož, Varaždin, and Dubrava form the Hydro North group of reservoirs and hydropower plants run by the HEP Group. Lake Dubrava serves the Dubrava Hydro Power Plant, which was built in 1989.
With an area of 17.1 km2, it is the second-largest lake overall in Croatia, and also the country\\\\\\\'s largest artificial lake.
