Coomera Catchment Management Plans

Several catchment and waterway management plans, studies and on-ground projects have been developed for the catchment as listed below:

  • Environmental Inventory of the Coomera River Catchment and its Tributaries (WBM, 2003)
  • Coombabah Creek Environmental Inventory Management Plan (GHD, 2003)
  • Coombabah Creek Catchment Stormwater and Waterway Management Plan  (KBR, 2007)
  • Saltwater Creek Foreshore Master Plan (Griffith University & Belleng VDM, 2008)
  • Draft Saltwater Creek Stormwater Management Plan (BMT WBM, 2010)

Restoration projects

Coomera River Estuary Stabilisation Project, Damian Leeding Memorial Park

In 2015 the Coomera River foreshore in the upper estuary at the Damian Leeding Memorial Park was experiencing severe erosion and destabilisation of the bank. The City managed an innovative and multi-focused restoration treatment to stabilise the foreshore. An erosion assessment commenced in 2016 and the stabilisation works were finished in April 2018. These works protect the foreshore bank from erosion and keep our park safe. The project also improves the river health and creates mangrove and fish habitat. Hardwood trees and fallen trees were used for this unique project.

Our Catchment Management Unit commenced a five year monitoring program with third year science students from Griffith University. Observations so far include:

  • sediment deposition around the logs
  • no more fallen trees
  • new mangrove seedlings growing along the foreshore
  • birds, fish and other aquatic fauna using the site.

Saltwater Park Coir Log Trial

In 2010 the City undertook the Saltwater Creek Coir Log Trial in response to the Saltwater Creek Foreshore Master Plan. The trial was undertaken in Saltwater Park, Helensvale Road, Oyster Cove and involved battering the eroded banks and placing coir logs (made of coconut husks) in the toe for protection from wave action. The upper and lower banks were planted with native plants suitable to the area. Mangrove restoration works were commenced in the intertidal area. This restoration takes a minimum of five years.

The trial was supported by undergraduate students from Griffith University, who surveyed the success of several aspects of the project. The engineering students assisted in the design of the foreshore protection (coir log configuration) and the science students developed a survey to measure the increase in habitat for flora and fauna. The City sends annual reports to Queensland Fisheries describing the recovery of the mangrove habitat and integrity of the coir logs protecting the foreshore.

Little Clagiraba Reserve Rehabilitation Plan

The rehabilitation and revegetation of the riparian zone of Clagiraba Creek commenced in 2009 and is ongoing.  A site plan was developed by the City's Natural Areas Management Unit allowing several stakeholders to continue working on this project. Works include weeding, planting, mulching, watering and monitoring which is being carried out by stakeholders such as the Coomera River Catchment Group, and students from local schools together with the Gold Coast Waterwatch team and Council. The water quality and annual in-stream macro invertebrate surveys measure the overall ecosystem health, which will give us an indication of the success of the works over time.
