The Gippsland Lakes, in eastern Victoria, consist of a series of shallow coastal lagoons enclosed by sandy barriers, the outer barrier forming the Ninety Mile Beach. The largest lakes are Wellington, Victoria and King. The main lakes cover 340 sq km, with a shoreline of 320 km. Several rivers feed the lakes system which has a surface area of about 360 sq km. At the time of European settlement, the outlet to the sea was at the eastern extremity of the lakes, about 6 km from the present entrance.
