Is The Lake Safe to Swim in?

This question is asked quite often. Historical monitoring suggests that water quality is generally of a high standard suitable for primary contact and recreational activities.

City of Gold Coast tests water for E.coli weekly in summer. Test results take 48 hrs and if continued high results are recieved, the lake will be closed. This last occurred in 2007.

There is a strong link between rainfall events and the health of our waterways.  Rainfall often collects pollutants from streets, gardens and farms, before it is flushed into our creeks, rivers and oceans via the storm water system. Stormwater runoff can increase bacterial levels in the water and on occasion make them temporarily unsafe for swimming.

City of Gold Coast City is currently monitoring 26 popular recreational water locations within the Gold Coast (including Lake Hugh Muntz). These areas include a combination of our open beaches, creeks, estuaries, enclosed lakes and swimming enclosures.

As a general precaution it is recommended that swimming is avoided during and:

  • one (1) day after heavy rainfall at open beaches.
  • three (3) days after heavy rainfall at river, estuarine and lake locations (such as Lake Hugh Muntz).

How Can You help Keep all our Waterways Clean?

✓Use designated toilet facilities.

✓Ensure young children have frequent toilet breaks.

✓Dispose of human waste correctly when boating and do not discharge sewage, litter or other waste into recreational waterways.

✓Avoid swimming if you have symptoms of diarrhoea or vomiting.

✓Clean up after your pets, ensuring faeces do not enter the stormwater system or waterways.

✓Report sewage spills to your local water utility and report other pollution incidents to your local government.

✓Maintain on-site sewerage facilities such as septic systems, contact your local government for advice.

✓Ensure household stormwater is not connected to the sewerage system.

✓Take home with you and pick up any litter you see.

2014 Water Quality Results Released

The latest water quality results unfortunately show record levels of nutrients, including Phosphorus and Nitrogen, particularly in the middle of the year. This increase coincided with the sand replenishment works that started in the middle of the year. Residents showed concern over the cleanliness of the sand used in the works. The disturbance of bottom sediments as well as the collapse of a retaining wall with subsequent testing of foreshore stability has added greatly to nutrients in the lake.


Fortunately nutrient levels have decreased toward the end of the year but still remain well above the Water Quality Objectives for a healthy lake.

The results are disappointing  as the care group were looking forward to some improvement in water quality as a result of the installation of litter baskets in all drains in March 2014. Hopefully the 2015 water quality results will show some positive results!
