Innovative drainage systems at developments such as Lynbrook Estate treat stormwater to improve the quality of waterways.
Dandenong Creek is the major waterway in the catchment and its source lies in the forested Dandenong Ranges National Park, where waterway health is excellent. Once out of the forest, the creek flows into the urban areas of Boronia and The Basin and its health declines significantly. The upper part of the creek discharges to the Liverpool Road Retarding Basin, where native plants and the rare Swamp Skink can be found. In its middle section, the creek is urbanised and in places has been straightened to reduce flooding. Although quite urbanised, significant corridors of parkland still remain and support environmental values, including native plants and the threatened Dwarf Galaxias.
The creek has been modified as it runs through urban areas for the remainder of its length to Mordialloc Creek, Patterson River and Port Phillip Bay. Key issues for the waterway are protecting threatened flora and fauna, reducing the impact of stormwater, weeds, loss of habitat and barriers to fish and fauna movement.
Improvement works: The focus of recent works has been erosion control, reinstating the creek's natural channel form, replanting native plants and establishing major wetlands to treat stormwater run-off and improve water quality. Replanting works are planned and the section from Heatherton Road to Clow Street, Doveton, has been examined in terms of stability and the potential to restore habitat in this area.
