Loch McNess, a freshwater lake located near Yanchep in the north of the coastal plain in Perth, Western Australia, is part of the Wanneroo wetlands a chain of lakes. It is part of the Yanchep National Park and named after Sir Charles McNess, a wealthy Western Australian philanthropist. Galaxiidae (fish) and Gilgies (freshwater crayfish) are endemic to the region. Introduced species include mosquofish (Gambusia). The lake is also known as Wagardu Lark by the Nyoongar aboriginals and along with the caves is of significant cultural importance including for boating outings. Since 1943 people have seen an increased decline in water levels and there is not enough water for these activities at present.
