Vision: Werribee catchment community values, enjoys and actively participates in managing the health, connectivity and resilience of our rivers, estuaries and wetlands Goals: • Waterways and water resources support and are supported by balanced and sustainable practices within industry, agriculture and the growing population. Innovation and knowledge guides appropriate use of our waterways. • Viable, healthy, resilient and connected ecosystems across the catchment. • Special places (rivers, estuaries and wetlands) within the catchment are recognised and managed for their significant values. • Our community appreciates the values of our waterways and is engaged to positively and actively contribute to waterway outcomes.

Target is to maintain as moderate. Fish score is currently very low, but can be improved to moderate through improved instream connectivity.

Cherry Main Drain Management Unit
Cherry Creek was once a drainage line with a series of shallow wetlands and ponds on basalt plains populated by native grasses around Laverton and Altona. Today its form has been substantially modified to improve drainage and reduce flooding on nearby industrial land. A large coastal swamp in its lower reaches has been formed into a retarding basin and the very popular recreation area, Cherry Lake. Sedgeland around the lake is home to the rare Altona skipper butterfly and several species of waterbirds.

Laverton Creek Management Unit
Laverton Creek originates in Ravenhall immediately south of the Western Freeway and passes through Derrimut, Truganina and Laverton before discharging to Port Phillip Bay at Altona. The main tributaries include Kayes and Dohertys drains, which join the creek in its lower reaches. The creek originally terminated in Truganina Swamp but a channel was constructed to drain water to the bay following flooding in the 1960s. The original grassland ecosystem has largely been replaced by farmland or housing. Patches of remnant landform and vegetation such as rocky Values – current status, trajectory and target (10-50 year targets) escarpments are significant surviving features of the creek.

Toolern Creek Management Unit
Toolern Creek is a small tributary of the Werribee River. The creek rises near Toolern Vale and flows through Melton and Melton South, separating the industrial and residential areas.

The Laverton Creek estuary opens to Port Phillip Bay near Altona adjacent to the Cheetham Wetlands. Rock weirs at 2.2 and 2.4 km upstream from mouth are likely to limit tidal flow and possibly fish passage at times of low fluvial flow. Modification has included the removal of native vegetation, some channelisation and construction of a basalt rock wall around the entrance. The substrate in the estuary is silty and riparian vegetation is primarily halophytic shrubs, grass, sedge tussocks and some exotic trees. There is moderate lateral connectivity between the waterbody and coastal saltmarsh communities north of Queens Street, and some connectivity to saltmarsh in the Cheetham Wetlands to the south.

The Little River Estuary is continuously open to Port Phillip Bay and extends about 3.6 km upstream from the river mouth. The estuary is in good ecological condition and largely unaltered. The estuary entrance is within the Western Treatment Plant and access to the estuary entrance is restricted. It is a partially mixed estuary with occasional defined ‘salt wedge’. The estuary forms part of the Port Phillip Bay (Western Shoreline) Ramsar site; shorebirds and waders use the estuary for feeding and roosting during high and low tides; marsh saltbush is a threatened species in this estuary; and the area is important for Orange‐bellied Parrot.

Page: 77 of 115 Cheetham Wetlands
The Cheetham Wetlands were originally a natural salt marsh and grassy woodlands; the area was later used as a saltworks. The later use created the lagoons, which attract many birds to the area. In 1996, the land was set aside to protect the wetland system and its diverse fauna and flora, including migratory birds. It is a Nationally Important Wetland, listed in the Directory of Imporant Wetlands Australia. Parks Victoria manages Cheetham Wetlands.

Page: 78 of 115 Cherry Lake, Cherry Creek
Cherry Lake, which is managed by Melbourne Water, is a flood retarding basin created in the 1970s to help prevent flooding of the rapidly expanding Altona residential area. The wetlands were converted to a lake with construction of retaining walls, levees, and flow channels. The lake and surrounding reserve is an important wildlife habitat and popular for recreation. The wetland provides habitat for the endangered Altona skipper butterfly (Hesperilla flavescens flavescens).

Page: 81 of 115 Deans Marsh, Rockbank
Deans Marsh at Rockbank incorporates several enclosed depressions (intermittent lakes) on the surface of the lava plain. They are sites of geological and geomorphic significance. Although there are many enclosed depressions on the Werribee Plains, most have been severely disturbed by draining, grazing, reclamation or other processes. The two wetlands at this site are therefore important remnants to illustrate the formerly complex drainage and surface water distribution of the plains. The shorelines of the lakes are low and rocky and illustrate the weathering of basalt boulders in a saline wetting and drying environment.
