About
Lake Vrana (Croatian: Vransko jezero), in the centre of Cres island, is a fresh water lake, 1.5 kilometres (0.93 mi) wide and about 4.8 kilometres (3.0 mi) long. The town of Cres has been supplied with drinking water from the lake since 1953, and the towns of Mali and Veli Lošinj received their supplies ten years later. It was thought at one time that the water in the lake was linked to some mainland source by underground streams, but it has since been established that in fact it originates from the atmosphere.
