Mudgeeraba Creek, Clear Island Waters & Robina Lakes Catchment Stormwater Management Plan

City of Gold Coast is implementing a stormwater management plan for Mudgeeraba Creek (including Worongary, Bonogin and Wyangan Creeks), as well as Clear Island Waters and Robina West and South Lakes. The plan provides an updated management tool to help implement strategies for stabilising environmental systems within this study area.

Project background

Gold Coast residents (and adjacent local governments) recognise that stormwater quality and quantity and the management of stormwater on local waterway health is of significance importance. This is reflected in local, state and federal legislation where proposed land changes in waterway catchments must be ecologically sustainable. The production and implementation of a stormwater and waterway management plan for the city's catchments can help ensure the expectations of the community and legislative requirements are achieved.

Study area

The Mudgeeraba Creek catchment lies within the southern region of the Gold Coast and forms part of the greater Nerang River catchment. It covers 121 square kilometres which accounts for almost a quarter of the total Nerang River catchment area of 493 square kilometres. The catchment consists of three major creek systems - Mudgeeraba, Bonogin and Wyangan Creeks. Worongary Creek is a neighbouring catchment to the north and is also considered in this study.

The Robina Lakes system is a manmade set of waterways within the Merrimac floodplain. The lakes receive run-off from the Mudgeeraba and Worongary Creek catchments and are separated from the tidal waters of Little Tallebudgera Creek and Boobegan Creek by three concrete weir structures. Floodwaters from the upstream catchments are stored in the lakes and then released across the weirs. The entry of waters to the lakes from upstream and adjacent catchments is the only source of flushing of the system. The three lakes that comprise the Robina System (Clear Island Waters, West Lake and South Lake) have a combined surface area around 180 hectares and a mean average volume of 12,000 megalitres (WBM 2003).

In April 2006, Council implemented the Mudgeeraba and Worongary Creek Catchment Management Study (GCCM 2006). A copy of this catchment study is at any Gold Coast City Council public library. As part of this study, water quality modelling was undertaken in these catchments. The study showed pollutant loads were predicted to increase as a result of planned development and increased run-off. The study recommends implementing a stormwater management plan and the construction of stormwater quality improvement devices to mitigate against these increases.

In 2006, the former Environmental Protection Agency (now Department of Environment and Science) listed Environmental Values (EVs) and Water Quality Objectives (WQOs) under schedule 1 for the Nerang River in the Environmental Protection Policy (Water) 2009. All tributaries of the Nerang River such as Mudgeeraba, Bonogin and Worongary creeks are included in this document.

Study objectives

The objectives are to:

  • provide a balanced and integrated approach to stormwater management (environmental, hydrological, social and economic issues) that will assist Council to deliver the City's Bold Future vision
  • assess the potential impacts of existing and future development on water quality (EVs), flooding and flood levels within the main channel, floodplains and tributaries in the study area
  • identify technically feasible areas suitable for the implementation of water sensitive urban design (WSUD) features and water cycle management initiatives (e.g. swales, bio-retention drainage devices, natural channels, precinct-style wetlands, roof water tanks or stormwater reuse)
  • investigate options to mitigate flooding for a range of flood events (i.e. Q2, Q5, Q20, Q50 and Q100) under existing and future development conditions
  • establish stormwater quality management planning priorities (including the sequential implementation of the management measures) for individual sub-catchments
  • develop a specific stormwater quality management strategy for the entire study area
  • fulfil legal requirements for local management of urban stormwater run-off and duty of care for the management of environmental resources under the EPP Water and Environmental Protection Act 1994
