14027: Lake Yangebup nutrient stripping basin and living stream
Lake Yangebup is a regionally significant flora and fauna reserve within the Beeliar Regional Park. The Tramways Reserve borders Lake Yangebup and forms part of the green corridor connecting Lake Yangebup, Kogalup Lake, Thompsons Lake and the Harry Waring Marsupial Reserve within the City of Cockburn. The City of Cockburn and the Department of Parks and Wildlife work closely to responsibly manage and enhance the condition of the reserves and parks within the Beeliar Regional Park.
Lake Yangebup is one only a few remaining wetlands in the metropolitan area that continues to hold water year round and as such it is a haven for waterbirds and a wide range of fauna and flora species. However the lake is eutrophic (ENV Australia 2009) containing high levels of nutrients. A natural basin adjacent to Lake Yangebup will be re-contoured to act as a living stream nutrient stripping basin that will significantly lower nutrient levels in the lake, provide additional wetland habitat, and enhance the amenity for Tramway Reserve Trail users and local residents.
Experienced contractors will be engaged to design and build a nutrient stripping basin and living stream to return the water to the lake, with design input from, and construction supervised by the City of Cockburn. Community volunteers under the supervision of the City of Cockburn Bushcare Officers will plant local, native, nutrient stripping species (sedges) in and around the basin. A solar pump will be installed to lift nutrient rich waters from the lake to the stripping basin, and nutrient stripped waters will return (gravity driven) to the lake via the living stream and via the superficial aquifer.
