In 1958, it was thought that the redevelopment of lake would cause the waterbirds to disappear, as it was believed the development would destroy the reed beds and
paperbark around the lake, which provided habitats for the birds. It was suggested that part of the lake should be left undisturbed, or for an island to be established. In 1968, the reed island was created by dredging a channel around a section of the bank, hoping to provide breeding sites for the birds. == References ==
