The Lake MacLeod wetland area lies adjoins Gnaraloo’s eastern boundary
Lake Macleod is approx. 120km long and 10 – 40km wide. The lake is normally dry, but occasionally fills with water after heavy rains. Water from the Indian Ocean also passes 18km underground through a karst system (coastal limestone) and surfaces at sinkholes and vents.
The northern ponds are one of the most important sites for migratory shorebirds in Australia with over 50,000 water birds sited every year. 70 species have so far been identified with 28 of them being listed on the Australian, Japan and China migratory agreements. The globally threatened Asian Dowitcher has also been recorded.
Lake MacLeod also supports the world’s largest inland mangrove habitat and is considered to be of high international significance. This system supports various insects, crabs, molluscs, nematodes, annelids, arachnids and various native fish species.
