The Gippsland Lakes were formed by two main actions. The first was by silt from the rivers creating river deltas. The Mitchell River created silt jetties which run into Lake King for several kilometres. The second action was the sea in Bass Strait which created the Ninety Mile Beach which blocked the rivers from reaching the sea.
Once the rivers were blocked the water level of the lakes would gradually rise. The water would finally break through the barrier beach and the level would drop to sea-level. Eventually the beach would close-off the lakes and the cycle would begin again. Sometimes it would take many years before a new channel to the sea was formed and it was not always in the same place as the last one.
In 1889 a wall was built to fix the position of a natural channel between the lakes and the ocean at Lakes Entrance. This stabilised the water level, made a harbour for fishing boats and opened the lakes to shipping. This entrance needs to be dredged regularly, or the same process that created the Gippsland Lakes would maker the entrance too shallow for ships to pass through.
Due to the flooding, in 2011, Gippsland Lakes were experiencing bioluminescence.[1]
Environment
The lakes support numerous species of wildlife. There are two protected areas: The Lakes National Park and Gippsland Lakes Coastal Park. The Gippsland Lakes wetlands are protected by the international Ramsar Convention on wetlands. There are also approximately 400 indigenous flora species and 300 native fauna species. Three plants, two of them being orchid species, are listed as endangered.
Lake Wellington covers an area of 148.19 square kilometres. It is connected to Lake Victoria by McLennan Strait.[4]
Lake Victoria
Lake Victoria covers an area of 78.14 square kiolmetres.[4]
Lake King
Lake King covers an area of 96.84 square kilometres.[4]
Lake Reeve
Lake Reeve is a long lake, with many salt marshes.[4]
Lake Tyers
Lake Tyers is not connected to the other Gippsland Lakes, and makes its own entrance to Bass Strait.[4]
Lake Coleman
The eastern shore of Lake Coleman is part of the Lake Coleman Wildlife Reserve.[5] There is also a small reserve on the western shore called the Lake Coleman West Wildlife Reserve. The reserve covers an area of about 1500 hectares.[6] Most of Lake Coleman is used by the Department of Defence for training purposes.[4]
