Overview

Estuary name Wreck Creek
CMA West Gippsland CMA
Description

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.

Recent Events

Event Details
20-07-2018 Estuary Entrance Opening

Estuary opened naturally as a result of freshwater inflows

16-07-2018 Estuary Entrance Closure

Estuary mouth closed again following low rainfall and consistent ocean swells over the past couple of weeks.

16-07-2018 09:10
16-06-2018 Estuary Entrance Opening

An artificial opening was performed @ 7:30 am to alleviate the risk of inundating surrounding houses. Water levels were above 2.10m AHD with the sand berm height approximately 30 cm above the water level height (i.e. the water levels had the potential to reach a height greater than 2.4m AHD, which would have inundated some of the lowest lying houses). Significant rainfall was also forecasted for the days following this opening.

22-05-2018 Estuary Entrance Opening

An artificial estuary opening was performed at 6pm, with water levels at 2.18m AHD and the sand berm 0.50m above this height (i.e. water levels had the potential to reach 2.68m AHD, which would have inundated surrounding houses, which start at 2.4m AHD), if the forecasted rainfall transpired.

11-05-2018 Estuary Entrance Opening

An artificial estuary mouth opening was performed to alleviate the risk of inundating surrounding houses. With water levels reaching 1.95m AHD and a significant amount of rainfall forecast to come it was decided an opening was required (lowest house at 2.4m AHD).
