Wreck Creek

Active WGCMA Estuary Management Group West Gippsland CMA

Wreck Creek is a small intermittently closing and opening estuarine lagoon located on the western edge of Inverloch. From the coast the estuary follows Cape Paterson - Inverloch Road towards the Inverloch RACV resort, for approximately 800 metres, before the creek becomes fresh. The creek has two main branches, one that begins well above the RACV resort (including the resorts wetlands) and the other flows out of farmland through the residential area to the north. For the majority of the year two branches of the creek are mostly dry (apart from a few ponds and billabongs that have been sighted on private property upstream). These creeks begin to flow during wet times (winter / spring), and for the majority of the time the main habitat available to biota is the estuarine lagoon itself.
