The Gippsland Lakes are a network of coastal lakes, marshes and lagoons in East Gippsland, Victoria, Australia covering an overall area of about between the rural towns of Lakes Entrance, Bairnsdale and Sale. The largest of the lakes are Lake Wellington (Gunai language: Murla), Lake King (Gunai: Ngarrang) and Lake Victoria (Gunai: Toonallook). The lakes are collectively fed by the Avon, Thomson, Latrobe, Mitchell, Nicholson and Tambo Rivers, and drain into the Bass Strait through a short canal about southwest of Lakes Entrance town centre. History The Gippsland Lakes were formed by two principal processes. The first is river delta alluvial deposition of sediment brought in by the rivers which flow into the lakes. Silt deposited by this process forms into long jetties which can run many kilometres into a lake, as exemplified by the Mitchell River silt jetties that run into Lake King. The second process is the action of sea current in Bass Strait which created the Ninety Mile Beach and cut off the river deltas from the sea. Once the lakes were closed off a new cycle started, whereby the water level of the lakes would gradually rise until the waters broke through the barrier beach and the level would drop down until it equalised with sea-level. Eventually the beach would close-off the lakes and the cycle would begin anew. Sometimes it would take many years before a new channel to the sea was formed and not necessarily in the same place as the last one. In 1889, a wall was built to fix the position of a naturally occurring channel between the lakes and the ocean at Lakes Entrance, to stabilise the water level, create a harbour for fishing boats and open up the lakes to shipping. This entrance needs to be dredged regularly, or the same process that created the Gippsland Lakes would render the entrance too shallow for seagoing vessels to pass through. Due to flooding in 2011, Gippsland Lakes experienced blooms of bioluminescent Noctiluca scintillans. Overview Tourism The Gippsland Lakes provide a major hub for tourism, particularly for recreational boating and fishing enthusiasts. The lakes network can be explored by cruise, water taxi, or boat and kayak hire. On the fringes of the lakes are several tourist towns that swell to support the tourist trade, particularly in the summer months. Lakes Entrance is the largest of the towns on the lakes with a
