Ballina Shire CouncilWater Quality in North Creek - what (or who) is affecting our oyster industry?
Show project summary
This project utilises a partnership approach to investigate long standing water quality issues impacting on primary industry and ecosystem health. It aims to identify the particular land use issues contributing to compromised water quality in the catchment, using oyster deaths as the 'canary in the goldmine'. The use of the EcoHealth water quality monitoring program, supplemented by event based elemental and faecal coliform sampling and regular testing of oysters in a parallel timeframe, will build on previous work in the catchment to provide a scientific picture of the issues and contributing factors. It also continues the development of the successful EcoHealth WQ monitoring program (which incorporates the NSW MER Indicators) in North Coast estuaries. Findings will be applicable to the wider Richmond River estuary.
Bega Valley Shire CouncilBega Valley Shire Estuary Monitoring program Show project summary

    Clarence Valley CouncilClarence Ecosystem Health Monitoring Program (“Ecohealth”) Show project summary
    The development of a standardised means of collecting, analysing and presenting riverine, coastal and estuarine assessments of ecological condition has been identified as a key need for Coastal Catchment Management Authorities and Local Councils who are required to monitor natural resource condition and water quality in these systems. Using the framework of the South East Queensland Ecosystem Health Monitoring Program (EHMP) and protocols developed by the NSW MER Estuaries team, this monitoring program will provide consistency in monitoring and reporting, and establish the partnerships required for local and regional dissemination of outcomes. This monitoring program will provide a means of benchmarking the health of the estuary against historic data and will provide a vital mechanism to educate the community about estuary health and the issues influencing it. The Project will also provide a means of refining and updating the remedial actions and direction of the established EMPs for the estuary and contribute to SOE reporting.
    Coffs Harbour City CouncilCoffs Creek Estuary Management Plan Show project summary
    The project will be managed by the Coffs Harbour Coast and Estuary Management Advisory Committee and will develop a plan of management for the Coffs Creek Estuary in accordance with the Estuary Management Manual. The project will include the assembly of existing data on the creek, the development of an Estuary Processes Study, Estuary Management Study and Estuary Management Plan, of which prioritised strategies can then begin to be implemented.
    Coffs Creek Infilling and Hydraulic Capacity Show project summary
    The nature of the Coffs Creek catchment means that Coffs Creek is subject to heavy sediment loads. This ongoing sedimentation is encroaching on stormwater infrastructure and exacerbating flooding and estuarine issues. This project will be in the form of a technical study which will investigate the sources and settlement points of sediment throughout Coffs Creek (including modelling, undertaking creek depth cross-sections, sediment sampling, aerial photograph analysis, and modelling the hydraulic and flushing capacity of the estuary). This technical study will coincide with the Coffs Creek Estuary Management Plan and Stormwater Management Plan (Review) and will assist in management options for the estuary.
    Pipe Clay Lake: Stormwater Community Education Program Show project summary
    This project is designed to improve the water quality of stormwater and catchment inputs to improve estuary health and to reduce the percentage of time that harvesting of wild resources is not safe (e.g. reduction in pathogen inputs to the system as determined by bacteriological indicators). This will include, gutter stencilling, signage, bins and bags for dog owners, information packs for existing and new residents and articles in the community newsletter. There is high potential for this to improve stormwater quality (in terms of nutrients, sediments and other pollutants as well as bacteriological indicators) as a number of interested community representatives from Corindi Beach were not aware that stormwater was not treated and that town stormwater ultimately flowed to the estuary.
    Eurobodalla Shire CouncilEEC Conservation works across Eurobodalla Estuaries Stage 3 Show project summary
    This project will control threats in the five major estuaries of the Eurobodalla Shire (Clyde, Tomaga, Moruya, Tuross/Coila and Wagonga estuaries) to protect and enhance the condition of key estuarine Endangered Ecological Communities (Coastal Saltmarsh, Swamp Oak Floodplain Forest and Bega Candello Dry Grass Forest) in high priority locations. The project will implement key environmental actions identified within the Estuary Management Plans for these areas. The project will also involve undertaking on-ground works and implementing localised community education programs at each target site to improve the condition of these habitats and increase the communities’ awareness and participation in environmental protection works. On-ground works will include weed control, controlling access to public areas and revegetation with planting at priority sites by recreational fishing clubs and school groups.

It will incorporate climate change impacts and sea level rise predictions and involve collecting field data and utilising the eShorance tool to determine the impacts of sea level rise on the foreshore of Wallis Lake. This information will be used to undertake a desktop analysis on the impact of climate change on valuable ecological communities such as saltmarsh and mangrove communities.
    Wallis Lake Estuarine Islands Weed Management - Stage 1 Show project summary
    This project will protect and enhance wetlands of National Importance within the Wallis Lake estuary through the reduction of invasive species, which have been recognised as a threatening process. Due to the remote nature of the site and the complexity of the issue, the project will be broken into a multi staged approach. This project will implement Stage 1, focusing on Mathers and Cockatoo Islands within Wallis Lake. These islands have been identified as a priority in the Wallis Lake Crown Estuarine Islands - Weed Management Strategy 2010. Both of these islands have a high resilience to invasive species and have been deemed to have the highest chance of native regeneration. Works will involve the use of contractors, targeting specific weed species at different times of the year to ensure maximum weed treatment is achieved.

    Water quality & habitat improvement addressing riverbank erosion & enhancing riparian vegetation Show project summary

    The Wallamba River is in the Wallis Lake Catchment near Forster/Tuncurry within the Great Lakes Local Government Area. It is exposed to severe bank erosion due to past vegetation clearance, ongoing cattle grazing and wash from boats. Sedimentation downstream is impacting on the ecosystem health of Wallis Lake. Sedimentation directly affects oyster leases and turbidity reduces the depth at which seagrass will grow to, thus reducing fish habitat. This project will address the water quality decline associated with bank erosion and disturbance of the riparian zone through the installation of temporarrock fillets/revetment to allow the establishment of mangroves to protect the toe of the riverbank from wash. In addition stock exclusion fencing and revegetation of the crown foreshore reserve will restore 12.7 hectares of estuarine riparian and wetland vegetation, thus improving significant aquatic and terrestrial habitat and providing bank stabilisation.

    Hornsby Shire CouncilImpacts of climate change on estuarine wetland & migratory waterbirds in lower Hawkesbury estuary Show project summary
    This project will undertake a risk assessment, through survey mapping and modelling to determine where important migratory and estuarine waterbird populations may be lost or re-established as a result of climate change. Impacts considered include sea level rise scenarios, altered inundation regimes and altered hydrodynamic flows. This project builds on work conducted during the 2009-2010 financial year and will:
    • Increase the baseline data on estuarine waterbird species distribution and abundance
    • Improve protocols for monitoring estuarine waterbirds as indicators of climate change
    • Examine climate change impacts on estuarine waterbird habitats using GIS, LIDAR and Digital Elevation Models (DEM)
    • Further develop adaptive actions for incorporation into the Lower Hawkesbury Estuary Management Plan

    The project will fulfil data gaps identified to enable estuarine Councils to manage wetland and migratory bird habitat within the Lower Hawkesbury estuary into the future. This will ensure that sites with current and potential value are protected by relevant planning instruments and/or capital works programs.

    Hunter-Central Rivers Catchment Management AuthorityHunter River (Ash Island) Bank Stabilisation Project - Riverside Park Show project summary
    This project seeks to stabilise the eroding river bank at Riverside Park at Kooragang Wetlands (Ash Island) in the Hunter River estuary through the construction of rock fillets and rock revetment and revegetation. Rock fillets will promote the recovery of mangroves and riparian vegetation, leading to improved fish habitat. Rock revetment will prevent further erosion of the river bank while allowing public access (fishermen) to the river bank. Revegetation with local native riparian species will help protect the top of the river bank, increase biodiversity and enhance native habitat.
    Riparian restoration for stabilisation and biodiversity, Hunter Estuary, Ash Island Show project summary
    This project will revegetate 500m of the riparian zone with local native species to help redress the degradation of the riparian zone due to clearing and invasion of exotic herbaceous vegetation. This project will augment previous works of removing grazing from the intertidal zone, which allowed the regrowth of mangroves, and re-establishing a shelterbelt of local native woodland species along the river bank. This final stage will restore the protective, overhanging native vegetation which will provide shelter for fish; restore native biodiversity and provide long term stability for the river bank, especially during flooding to buffer against the early effects of sea level rise.
    Stockton Sandspit Habitat Restoration - Hunter Estuary Show project summary
    The Stockton Sandspit in the Hunter estuary is one of the State's most significant migratory shorebird roosts; is of international significance as a Ramsar site; and is a key destination for bird observers and international delegations. In this project, 1.5ha of local native habitat will be restored along 210m of river bank on the approach to the shorebird roost. This ecosystem will provide a more natural, biologically complementary ecosystem to the roost area as well as becoming a significant enhancement to native biodiversity in it own right.  


    Hunters Hill CouncilLane Cove River - Stormwater improvement works to protect saltmarsh, Boronia Park
    Show project summary
    Boronia Park along the Lane Cove River is part of an important estuarine habitat link between Sydney Harbour and Lane Cove National Park. It is 15 hectares and forms part of the Great North Walk. Uncontrolled stormwater runoff is resulting in erosion, sedimentation and weed infestation of key Coastal Saltmarsh and Swamp Oak Forest communities on the Lane Cover River. Stormwater quality improvement works will reduce erosion and sedimentation in these communities. It will also improve water quality in the estuary. Bush regeneration works will restore 3.5 ha of core habitat for threatened fauna including Grey-headed Flying Fox and Powerful Owl.


    The project has been identified as a high priority action in the five-year estuary vegetation rehabilitation plan for the reserve. The project will consolidate bush regeneration works funded by the CMA in Sydney Turpentine Ironbark Forest and Coastal Saltmarsh and funded previously by OEH along Brickmakers Creek riparian zone.

    Lake Macquarie City CouncilDeciding for the Future - sea level rise risk and community values Show project summary
    The project will identify the main factors - social, ecological, economic - that influence vulnerable communities' response to the effects of sea level rise in coastal estuaries. It will consider the possible responses to sea level rise - retreat, protection, modification - and prepare a decision-making matrix to help communities and planners understand the process, and make decisions on the best course of action for future planning and risk management, within an uncertain biophysical environment. The decision making matrix will weight factors based on analyses such as cost-benefit analysis, and estimations of environmental and social impact. A structured process of community consultation will allow community values and expectations to be included in the weighting of factors in the matrix.
    Improving foreshore & littoral habitats Lake Macquarie improve ecology & resilience sea level rise Show project summary
    The Lake Macquarie Estuary Management Plan identifies foreshore erosion, and the loss of foreshore (littoral) vegetation as being a key issue affecting the health of Lake Macquarie. While significant improvements have already been achieved through completed foreshore and littoral vegetation works around the Lake (undertaken as part of the 'Lake Improvement Project') a number of high priority degraded foreshore sites remain. This project aims to remediate a number of prominent foreshore sites where active erosion is occurring and littoral vegetation has become degraded. Priority sites include Rathmines, Myuna Bay and Arcadia Vale. Remedial works involve the use of 'soft engineering' techniques, such as the re-instatement of cobble beaches, which have proved to be highly successful at other localities around the estuary. Outcomes from undertaking this project include water quality improvements, increased recreational amenity, improved littoral habitats, as well as increased corridor connectivity.
    Sea Level Rise Adaptation by Design - low-impact protective measures for estuarine foreshores Show project summary
    The project will develop detailed design guidelines for works to protect property on estuarine foreshores from inundation and recession as a result of sea level rise. The proposed works, which may include vegetated berms, cobble beaches, and buried rubble walls, will preserve natural foreshore processes, and will protect property while preserving ecosystems and water quality. The project builds on recent studies of the effect of sea level rise on estuarine foreshores in Lake Macquarie, and earlier work by the Office of the Lake Macquarie and Catchment Coordinator on soft engineering designs for foreshore and streambank stabilisation. The guidelines will be incorporated in Council's Development Control Plan, and will be suitable for use by other coastal Councils
    Wetland and Saltmarsh Rehabilitation in Lake Macquarie Show project summary
    The project aims to address the on-going degradation in wetland and saltmarsh areas around Lake Macquarie by undertaking wetland/saltmarsh restoration works in priority locations (as identified in the Lake Macquarie Estuary Management Plan and subsequent management plans). These works aim to increase the improve water quality, restore/preserve habitat values on these areas, as well as improve their buffering capacity for predicted sea level rise.
    Lane Cove Municipal CouncilGore Creek - Stormwater Works to Protect Saltmarsh (EEC) Stage 1 - Planning, Design Show project summary

    Stage 1 of this project is for the investigation, design and documentation for erosion control works on a tributary of Gore Creek at Greenwich. The erosion control works being designed are needed to reduce the amount of sediment and nutrient laden runoff from entering the bay at the mouth of the creek where there are patches of saltmarsh. Water quality and sediment loadings will be monitored to assist with planning and design works. A project plan, including detailed designs, will be produced at the completion of Stage 1 of the project.

    Stages 2 and 3 of the project will involve future implementation of the plan - i.e. installation of the recommended devices and environmental controls to reduce the amount of sediment and other run-off entering the bay, leading to a significant improvement in water quality. Works will also help to protect the Endangered Saltmarsh Vegetation Community in Gore Creek Reserve by reducing the sediment loading and improving water quality.

    Manly CouncilManly Lagoon Estuary Health Improvement - Sediment Interception Program
    Show project summary
    Manly Lagoon receives inflows from three creeks (Manly, Burnt Bridge and Brookvale Creeks). The Lagoon is now 10% of its original size and is considered one of the most polluted recreational waterways on the east-coast of Australia. It suffers from high levels of sediment pollution and eutrophication. Swimming, boating and fishing are prohibited due to the poor water quality. The stormwater system transports high levels of sediment, nitrogen and phosphorus to the Lagoon, with serious implications for estuary health. This project is for the construction of an online 180 cubic metre sediment basin within a major tributary into the Lagoon, Burnt Bridge Creek at Manly West Park, Balgowlah, as part of a sediment and organic matter interception program to improve estuary health and water quality in the Lagoon. Further, signs will be erected around the basin to educate the public and community on stormwater management in the Creek’s catchment.

    The project will fulfil data gaps identified to enable Pittwater Council to manage migratory bird habitat within the Pittwater estuary into the future. This will provide greater protection for sites with current and potential habitat value.

    Urban sedimentation and pollution audit in the Pittwater Estuary: Stage 1
    Show project summary
    Careel Creek and Mona Vale Main Drain are tributaries of the Pittwater Estuary, they drain urban, commercial and industrial lands within the suburbs of Avalon, North Avalon, Bilgola Plateau, Mona Vale and Bayview. Careel Creek is within the Careel Creek Catchment, around 4.5km2, and Mona Vale Main Drain is within the Winnerremy Bay Catchment, around 5.2km2 (which also drains Cahill Creek).


    The Pittwater Estuary Management Plan has identified these catchments as problematic in terms of urban pollution and sediment runoff. This project will undertake an urban pollution and sediment runoff audit for both catchments. The audit shall include assessing activities and land-uses which constitute potential sources of pollution. Water quality monitoring, sediment sampling, detailed mapping and site inspections will be carried out. The audit will prioritise areas of greatest impact, and provide key hot spots to focus mitigation measures on, to reduce sediment and pollution discharges into Pittwater Estuary.

    Shoalhaven City CouncilAssessment of Catchment Inputs Jervis Bay & likely role of anthropogenic influences on algae blooms Show project summary

    Since September 2009, there has been large amounts of green algae (Microdictyon umbilicatum) washed up on Jervis Bay beaches. This has raised community concerns related to smell, amenity, potential heath impacts and the impact on the economy (tourism) and recreational activities.

    The cause of the bloom has not yet been determined. The Jervis Bay Marine Park Authority is conducting research on the algae in partnership with the University of Wollongong as not much research has been conducted on Microdictyon umbilicatum to date. In addition, there is a need to determine if anthropogenic catchment inputs could be causing the bloom so that preventive management measures can be put in place. This project will investigate catchment pollutant sources and assess their potential influence on the water quality of Jervis Bay and algae blooms.

    Estuary Health Monitoring and Reporting Show project summary
    This project will build on the current Ecosystem Integrity Index project for the Shoalhaven River and other catchment areas. The project will redesign the current routine monitoring program undertaken by Council across the estuary network to align it with the statewide MER and the Southern Rivers Catchment Management Authority's Estuary Benchmarking project. A working group has been established to mentor this review.
    Sutherland Shire CouncilNorth West Arm Estuary Management Plan Show project summary

    In conjunction with the Port Hacking Management Panel and community, Council carried out an extensive review of the 1992 Port Hacking Plan of Management. The resulting Port Hacking Integrated Environmental Management Plan was adopted by Council in February 2009. The Plan contains a detailed assessment of issues facing Port Hacking and recommends various actions to address these issues.

    Specific concerns in the North West Arm catchment include, flooding, degraded water quality, erosion, siltation, littering and weed infestations. This is due to a number of factors such as the nature of the catchment, its topography, land use, areas of population concentration, level of ongoing construction, condition of tributaries and natural characteristics of the estuary. It is expected that a North West Arm Estuary Management Plan will propose a range of actions to address these concerns.

    Warringah CouncilEstuarine Health Assessment of Coastal Lagoons Show project summary
