Lake Tributary Flood Studies
Let’s thrive in Lake Mac and continue building a resilient City by planning for flood risks. We have adopted six flood studies and floodplain risk management studies and plans with the help of our community. Now it is time to study the eight tributary catchments across Lake Mac to inform risk management plans protecting residents and property.
The tributary catchments include:
1. Plains Gully Creek at Swansea and Caves Beach
2. Sheppards Creek at Croudace Bay and Valentine
3. Muraban Creek at Floraville and Belmont North
4. Mills Gully Creek at Belmont and Valentine
5. Fullers Creek and Freshwater Creek at Bonnells Bay
6. Mannering Creek, Swampy Creek and Wyee Creek at Wyee
7. Postmistress Creek at Sunshine and Morisset East
If you are a resident within the study areas, we need your help. Please provide any information on flood history in your area, including photographs, personal recollections or flood marks. Share your information and upload your photos via our quick survey or our interactive map before Friday 17 April. Stay up to date with the project by joining our eNewsletter - subscribe below.
We’ve appointed WMAwater, a specialist consultancy in flood models and floodplain management, to carry out the eight flood studies. The studies will be undertaken in accordance with the NSW Government's April 2005 Floodplain Development Manual and other related guidelines. The project is scheduled for completion later this year.

Right now, we recognise this tributary is a small catchment located at Caves Beach and draining into Black Ned’s Bay. Nuisance flooding has been recorded at the downstream end but projected sea level rise (exacerbated by localised flooding) may be an issue at Bowman Street where the Plains Gully Creek flows into Black Ned’s Bay.
