Lake Hugh Muntz

Constructed in the early 1980s, Lake Hugh Muntz is about 17 hectares in area, located in Mermaid Waters on the Gold Coast. It is set in a developed suburb with a relatively small catchment of around 43 hectares. Run-off into the lake is controlled through 16 stormwater pipes that discharge into the lake at various locations.

History of Lake Hugh Muntz

Construction of Lake Hugh Muntz started in the early 1980s. The lake is in a well-established urban area in Mermaid Waters and is about 17 hectares in size and up to 12 metres deep in places. It holds around 704,472 cubic metres of water. The shape of the lake was designed to ensure maximum waterfront land, resulting in an extensive shoreline of 3298 metres.

Run-off from the catchment of around 43 hectares is controlled through 16 constructed stormwater pipes that discharge into the lake at various locations around the shoreline. Water discharge from the lake is via overflow pipes at Barrier Reef Drive and into the adjacent canal.

Prior to urban development, the site was part of an extensive wetland and floodplain, consisting of vegetation communities such as Melaleuca swamp land. There is little evidence of these historical communities remaining.

Pest plants and animals in Lake Hugh Muntz

Lake Hugh Muntz has a relatively low abundance of free-floating aquatic plant species. These species can congregate and create a mat-like appearance that some residents find visually unappealing. Presently, the following weed species are not known to be present in the lake despite it being a suitable habitat for them:

A number of pest aquatic fish species have been found in Lake Hugh Muntz with residents expressing concerns over Tilapia (Oroechromis mossambicus) populations. Unfortunately, pest fish species are introduced into the lake through both accidental and intentional release. The following pest fish species are found in the lake:

Native plants and animals in Lake Hugh Muntz

Lake Hugh Muntz is a freshwater aquatic ecosystem artificially created during the residential development of the Mermaid Waters area. The lake provides a variety of freshwater habitat, from shallow vegetated and bare foreshores to deeper areas. While the lake provides limited habitat for most native species; more than 34 bird, five mammal, eight fish and one amphibian species have been recorded.

Native aquatic vegetation is an important component of freshwater ecosystems such as Lake Hugh Muntz. Aquatic vegetation provides habitat and food for a variety of native fish, birds and other wildlife. Plant growth also allows removal of excessive nutrients washed into the lakes, not just through the growth of plants but as a result of the habitat they provide for algae, epiphytes (plants that don’t require soil) and bio-films (colonies of micro-organisms), which filter out and consume nutrients in the water. Common native aquatic plant and animal species found, or likely to occur in Lake Hugh Muntz are:

Common native aquatic plants

Water quality monitoring

The City conducts a number of water quality monitoring activities within Lake Hugh Muntz.

  • What is Council doing to monitor water quality in Lake Hugh Muntz?

    Currently, Lake Hugh Muntz has a number of water quality sampling sites part of Council’s coordinated city-wide water quality monitoring program. For information on Council’s water quality monitoring program, please see Water Quality Monitoring and Management.

  • How can I help to improve Lake Hugh Muntz?

    The stormwater entering Lake Hugh Muntz is largely untreated, therefore the growth of aquatic plants is highly dependent on the condition of the catchment and the way in which residents use chemicals (e.g. fertilisers) and dispose of waste (e.g. grass clippings, dog faeces). It is vital that all residents ensure that fertilisers, detergents, pet droppings, lawn and garden clippings don’t wash into the lake. When washed into the lake, these substances break down into a ready supply of plant-available nutrients, stimulating further aquatic plant and algal growth.

  • Who manages revetment walls within Lake Hugh Muntz?

    Further information can be found on Revetment Walls.

  • Who do I contact when I find injured wildlife?

    If you find injured wildlife and can safely transport it, Currumbin Wildlife Sanctuary provides emergency veterinary care. Further information on injured wildlife can be found at Currumbin Wildlife Hospital Foundation.

    Alternatively, you can contact one of the Wildlife Rescue and Care organisations which can be found at Wildlife Rescue and Care.
