Lakes & Creeks
Over forty perched dune lakes can be found on K’gari. These lakes are formed when organic matter, such as leaves, bark and dead plants, gradually builds up and hardens in depressions created by the wind.
The island also has barrage lakes (the most famous being Lake Wabby), formed when moving sand dunes block a watercourse, and "window" lakes, formed when a depression exposes part of the regional water table.
