Sand dredged from Lake Conjola will be used as part of a beach stabilisation project at Mollymook.
The lake dredging is planned to take place after the school holidays, with more than 6,000 cubic metres used to repair erosion damage at both the lake entrance and at Blackwater Creek on Mollymook Beach.
Preliminary work is already underway at Mollymook, with fencing erected along Mitchell Parade near Blackwater Creek.
Shoalhaven City Council’s Ulladulla office manager Warwick Papworth said work was already being carried out in preparation for the sand to be delivered from Lake Conjola.
He said a rock wall and sand bag groin would be used to stabilise the creek and to prevent further coastal erosion towards the pumping station and to the north near private dwellings.
Storms have caused gradual erosion of the creek area which has been deemed at immediate risk of erosion during an extreme storm event.
Mollymook Beach is one of nine beaches in Shoalhaven which are especially vulnerable to coastal hazards, including beach erosion and flooding during storm events.
In recent times during storm events, Blackwater Creek has been breaking out to the south of the entrance, however, at other times in can swing to the north, creating a flood and erosion risk to the houses.
Once the wall has been built, 3,000 cubic metres of sand will be used to backfill and replenish the dune area.
It will be spread in front of the existing dune for a distance of approximately 300 metres and will include some revegetation with grasses such as spinifex to reinforce the existing dune, increase its resilience and providing added protection to public and private assets behind the beach.
