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.

Wreck Creek Mouth Condition Monitoring Site, located at the end of the Wreck Creek access path opposite 178 Surf Parade Inverloch.
14-07-2020 - 14-07-2020
In April 2020, following a large storm surge event, a new opening was formed at Wreck Creek. There are now two locations where the creek can flow out to sea. This site will be monitored in conjunction with the mouth condition monitoring site established several years ago (further east).

Site located at end of beach access path opposite 178 Surf Parade Inverloch. Site located on grassy mound (site of proposed Fluker Post).

Wreck Creek West end Opening
|23-06-2020 Estuary Entrance Opening
A natural estuary opening at the 'new' wreck creek opening (i.e. further west of the original opening) exposed a large Amazon Ship Wreck, before ocean swells covered it over again with sand later in the afternoon.
|24-04-2020 Estuary Entrance Opening
In April 2020, a new mouth was established at Wreck Creek. Traditionally when flows in the creek increased over late winter / spring, water would flow out of the sand berm into the ocean at the most easterly extent of the creek. In April large ocean swells removed a large section of coastal vegetation and separated the creek into two (i.e. an east and west tributary). Recent high creek flows have been flowing out to the ocean through this section of the creek ever since this event.
|05-04-2020 Estuary Entrance Opening
Following a significant down poor (around 40mm) the mouth of Wreck Creek was artificially opened to alleviate the risk of inundating surrounding houses.
|23-01-2020 Estuary Entrance Opening
After 40 mm of rainfall overnight, the estuary water levels increased rapidly from 1.4m AHD on the 22 nd of January, to 2.0m AHD on the morning of the 23 rd of January 2020. With steady inflows, consistent rainfall and a sand berm height of approximately 2.4m AHD, an opening was required to prevent the inundation of adjoining houses.
The estuary was completely fresh and the oxygen levels were good.
|08-11-2019 Estuary Entrance Opening
After 30mm of rain the mouth of Wreck Creek opened naturally to the ocean. The sand berm was at 2.15m AHD on the afternoon of the 7th of November, and the water level was at 1.85m AHD on the same afternoon. The water levels must have risen more than 30mm overnight to break through the sand berm.
