River Health Strategy

APPENDIX B1 – RAMSAR WETLANDS WITHIN THE CORANGAMITE CMA REGION The Ramsar Convention on Wetlands is an inter-governmental treaty that provides the framework for international cooperation for the conservation of wetlands, one of the most threatened habitats in the world. There are currently 1,150 wetlands listed under the Ramsar Convention. As a Contracting Party to the Ramsar Convention, Australia is required to meet a number of obligations including the maintenance of the ecological character of its Ramsar sites through conservation and wise use. Australia has 57 sites listed under the Convention, including 11 sites in Victoria of which parts of two are in the Corangamite Region, namely: ● Port Phillip Bay (Western Shoreline) and Bellarine Peninsula – specifically

Limeburners Bay and the Bellarine Peninsula (extending from Edwards Point to Barwon Heads)

● Western District Lakes – including Lake Corangamite (the largest permanent saline lake in Australia and the largest natural lake in Victoria).

B1.1 PORT PHILLIP BAY (WESTERN SHORELINE) AND

BELLARINE PENINSULA RAMSAR SITE Sites specific to the Port Phillip Bay (Western Shoreline) and Bellarine Peninsula Ramsar site located in the Corangamite Region include: ● Point Wilson to Limeburners Bay ● Swan Bay ● Lake Connewarre and Reedy Lake. This Ramsar site includes a variety of wetland types ranging from shallow marine waters to seasonal freshwater swamps. These areas support a large and diverse population flora and fauna, especially birdlife. Notable rivers and streams that flow into these Ramsar sites include: ● Barwon River (Lake Connewarre and Reedy Lake) ● Hovells Creek (Limeburners Bay) ● Yarram Creek and adjacent tributaries (Swan Bay).

-B1-


Values of Ramsar Site Lake Connewarre and Reedy Lake • The Connewarre wetlands absorb and recycle sediment, nutrients and other

pollutants from the Barwon catchment, improving water quality and flows in the lower Barwon River and adjacent coastal waters

• The Vegetation in Lake Connewarre State Game Reserve is very diverse, with 137 native plants. Forty Five (85%) of the 53 salt marsh which occur in Victoria occur at Lake Connewarre

• 135 species of avifauna have been recorded • Lake Connewarre contains the most extensive example of Wilsonia herblands

and Distichilis grassland in Victoria • Flows down the Barwon and Moorabool Rivers are important to the health of

Lake Connewarre and associated wetlands, and to the availability of water for regulating levels in Reedy Lake

• White Mangrove reaches its western most limit in Victoria in the Barwon River estuary

• Lake Connewarre State Game Reserve is the largest area of native vegetation on the Bellarine peninsula and Reedy Lake is the largest freshwater lake in central Victoria.

Point Wilson to Limeburners Bay • Two geomorphological sites of State significance – Hovells Creek (mid Holocene

sea level site) and Limeburners Bay (estuary) • Limeburners Bay contains a zone of Halosarcia halocnemoides (Grey Glasswort)

broader than is commonly found in Victorian coastal marshes • The largest stand of White Mangroves in Port Phillip Bay occurs in Limeburners

Bay • Limeburners Bay is probably the largest intact salt march complex: • Valuable fish breeding ground. Swan Bay • Valuable fish breeding ground • Forms part of the Harold Holt Fisheries Reserve, is listed on the Register of

National Estate and forms part of a Marine National Park (Port Phillip Heads Marine National Park)

• Rich diversity of habitat, including seagrass meadows, foreshore dunes, mudflats, salt marsh and remnant woodlands

• Sites of geological and Geomorphological significance are present.

-B2-


Threats to Ramsar Site • Stormwater represents a potential risk at Limeburners Bay, Reedy Lake and

Southern Swan Bay • Significant urban development adjacent or close to Limeburners Bay, Southern

Swan Bay and Lake Connewarre • Limeburners Bay, Lake Connewarre and Lake Murtnagurt are directly affected by

hydrological and water quality changes due to catchment processes and land use • Salinisation of the Lower Barwon Wetlands from diffuse saline discharge and

point sources in the Barwon River • Specific threats affecting values in the Hovells Creek catchment include degraded

riparian vegetation, Algal blooms, poor water quality, channel modification, stock access and loss of instream habitat

• Specific threats affecting values in the Barwon River and Catchment include bed and bank erosion, sediment and nutrient transport, salinisation, degraded riparian vegetation, stock access and changes in hydrology. There are numerous other threats

• Specific threats in the Swan Bay Catchment associated with streams and their catchments include loss of instream habitat, stock access, declining water quality, urbanization and stormwater inputs. Stormwater drains from eastern ocean grove along constructed channels through lakes and wetlands (Lakes Lonsdale and Victoria). Also, stormwater drains from parts of Point Lonsdale and Queenscliff.

B1.2 WESTERN DISTRICT LAKES RAMSAR SITE The Western District Lakes Ramsar site comprises nine separate lakes covering an area of approximately 32,898 Ha. The nine lakes include: ● Beeac ● Bookar ● Colongulac ● Corangamite ● Cundare

● Gnarpurt ● Milangil ● Murdeduke ● Terangpom

All lakes lie within the Lake Corangamite Basin with the exception of Lake Murdeduke which is located in the Barwon Basin and Lake Bookar which is in the Hopkins Basin. In the Lake Corangamite Basin, the Woady Yaloak River, fed by the Naringhill, Kuruc a Ruc, Mt Misery and Ferrars Creeks tributaries, is the basins major stream. Other streams include Pirron Yalloak, Dean, Spring Gully and Barongarook Creeks, Mundy Gully and the Gnarkeet chain of Ponds. Mia Mia Creek is the major waterway that feeds Lake Murdeduke.

-B3-


Values of Ramsar Site There are numerous values associated with Western district lakes Ramsar site. Environmental values include representativeness of wetland type and significant flora and fauna. Other values include natural function, cultural heritage, scenic, economic, education and interpretation, recreation, tourism and scientific. Five wetland types including areas of the State’s most depleted wetland habits and wetlands least represented. Lake Corangamite is the largest permanent saline lake in Australia and the largest natural lake in Victoria. More than 40 species of indigenous flora and 100 species of indigenous fauna have been recorded. Two flora species and three fauna species are considered nationally threatened and 2 flora and 25 fauna species are considered to be threatened in Victoria. A total of 16 bird species listed under the Japanese-Australia Migratory Birds Agreement (JAMBA), 19 species listed under the China-Australia Migratory Birds Agreement (CAMBA) and 26 species listed under the Bonn Convention have been recorded. In total the Western District Ramsar site provides important feeding and roosting habitat for 67 waterbird species. The Western District Lakes Ramsar site is a natural flood mitigation area, storing excess runoff and releasing it slowly during times of low stream flow. It acts as a sink for sediments and nutrients washed from the surrounding catchment. The Lakes have been a focus for the Djargurd Wurrung and Gulidjan Aboriginal people for thousands of years. Many archaeological sites have been registered including fish traps, surface scatters, middens and burial sites. There are European cultural heritage sites of note as well. In addition, the lakes have many scenic values resulting from past volcanic activity, economic values including a commercial eel fishery with an estimated value of over $1 million per annum and educational and scientific values. Recreation and tourism is popular in the lakes area with people partaking in activities such as camping, fishing, boating, bird watching and duck hunting. Threats to Ramsar Site Water diversion and regulation schemes have altered the natural water regimes of most of the nine lakes that form the western districts Ramsar site. The impact from these changes is most evident in Lake Corangamite where salinity has risen, water levels have fallen and the composition of biota has changed, resulting from the diversion of the Woady Yalloak River.

-B4-


Lake Beeac Surface water runoff is the main natural supply of water to this lake. There are no natural streams. Due to the extensive clearing of the surrounding catchment, surface runoff to the lake has increased, resulting in flooding of adjacent farmland. In addition, the former Beeac tip site is being exposed from wave action and the leachate of heavy metals and chemicals may pose a threat. Lake Bookar This lake is not in the Corangamite CMA Region. Lake Colongulac Camperdown sewage treatment plant has an EPA licence allowing the discharge of secondary treated wastewater into this lake. This has resulted in the deposition of heavy metals such as mercury. In addition, three other intermittent streams drain agricultural catchments into this lake. Lake Corangamite As stated above, water diversion and regulation schemes have had a dramatic effect on this lake. There are numerous streams and springs that flow directly into the lake, the most notable including Pirron Yalloak and Spring Gully Creeks in the south and Gnarkeet Chain of Ponds in the North. Within these streams and their catchments threats include stock access, degraded riparian vegetation, loss of instream habitat, algal blooms, declining water quality and channel modification. All these threats would have a negative impact upon the lake. Lake Cundare There are no significant streams associated with Lake Cundare. Surface water run off in an agricultural catchment is the main water supply for this lake. Lake Gnarpurt Major streams that flow into this lake include Salt Creek and Mundy Gully. Threats associated with these streams include bed stability, channel modification, declining water quality, algal blooms, degraded riparian vegetation, loss of instream habitat and stock access. All of these threats would have a negative effect on this lake. Lake Milangil No major streams are present.

-B5-


Lake Murdeduke Mia Mia Creek is the major stream that flows into this lake. Major threats associated with Mia Mia Creek include degraded water quality, algal blooms, degraded riparian vegetation, and loss of instream habitat. There is also a piggery on the shores of the Lake. Lake Terangpom Only intermittent streams flow into this lake. B1.3 SPECIFIC PLANS AND ACTIONS TO MANAGE

APPENDIX B2 – MARINE NATIONAL PARKS AND SANCTUARIES In June 2002, legislation was passed which made Victoria the first jurisdiction in the world to establish an entire system of highly protected marine national parks where activities such as harvesting, extraction of seabed materials, and dumping of waste is not permitted. The system comprises: • 13 highly protected marine national parks which feature representative examples

of Victoria’s marine habitats and their associated flora and fauna; and • 11 highly protected marine sanctuaries to protect small areas with significant

natural values. Within the Corangamite region, the following marine national parks exist: • 12 Apostles (including the tidal reach of the Gellibrand River) • Point Addis • Port Phillip Heads and the following marine sanctuaries: • The Arches • Marengo Reefs • Eagle Rock (including the tidal reach of Painkalac Creek) • Point Danger • Barwon Bluff (including the tidal reach of the Barwon River) The most serious issues in Australia’s environment stem from poor catchment use, and therefore declining water quality. Increased levels of nutrients and sediments are the major problems. Diffuse sources of sediments, nutrients and toxicants from catchments draining to the coast pose significant risk to the environmental quality of estuaries and shallow embayments in particular. The Senate Inquiry into Marine and Coastal Pollution (1997) concluded that the most serious threat to Australia’s marine environment stem from catchment activities. Furthermore, the State of the Marine Environment for Australia (1991) stated that integrated catchment management is probably almost as important to the sea as it is to the land. As such, a key recommendation of the Environment Conservation Councils “Marine, Coastal and Estuarine Investigation” states:

Catchment Management Authorities and Boards ensure that reviews of regional catchment strategies specifically address the impacts of land use and management on the marine and estuarine environment, particularly where important physical or biological features may be affected.

-B7-


B2.1 THREATS TO MARINE PARKS AND SANCTUARIES

ASSOCIATED WITH WATERWAYS. Catchment activities such as vegetation clearing, swamp reclamation and infrastructure development have altered drainage patterns and caused soil erosion. This has led to increased sediment and freshwater loads in coastal waters. Agricultural practices have resulted in nutrients and pesticides arriving in coastal waters from runoff, rivers and streams. The majority of Marine Parks and Sanctuaries within the Corangamite region are located in open coast areas. These areas are primarily influenced by wave energy and water depth, and to a lesser extent by freshwater inflows. The marine waters of bays, inlets and estuaries are influenced to varying extents by freshwater from surrounding catchments and rivers. These areas are important as they support seagrass beds, which play an important role in nutrient recycling. In addition, they provide habitat for a multitude of fish, invertebrate and algal species. Details of the marine national parks and sanctuaries with inflowing waters and associated threats are outlined below: Twelve Apostles Marine National Park The majority of this marine park is in an open coast area, therefore direct impacts from surrounding catchments and rivers would be limited. However, included within the park is the tidal reach of the Gellibrand River. There are numerous threatening processes within the Gellibrand river and its catchment that would have detrimental effects upon the estuary. These threats include loss of instream habitat, stock access, declining water quality, degraded riparian vegetation and instream barriers. In addition to the Gellibrand, the Sherbrooke River flows into the park near the western boundary. This waterway would have direct impacts on the park and threatening process in the catchments include minor erosion and agriculture in the middle and upper catchment.

-B8-


Point Addis Marine National Park The whole of this marine park is in an open coast area, therefore would be influenced by inflowing waters a minimal amount. However, there are unnamed waterways within the park that have relatively small and steep catchments. These waterways are subjected to high rainfall events and are eroding. These processes are being accelerated by human access in areas that are not fenced out to re-stabilize the dune and cliff system.

Port Phillip Heads Marine National Park In addition to its marine National Park status, Swan bay forms part of the Harold Holt Fisheries Reserve, is listed on the Register of the National Estate and is designated as part of the Port Phillip Bay (Western Shoreline) and Bellarine Peninsula Ramsar site. Swan Bay is a shallow embayment with numerous habitats including soft sediments (mud and sand flats), sea grass beds, mangroves and salt marsh. There are numerous waterways that drain into Swan Bay including Yarram Creek and other unnamed small streams. Threatening processes associated with these streams and their catchments include loss of instream habitat, stock access, declining water quality, urbanization and stormwater inputs. Stormwater drains from eastern ocean grove along constructed channels through lakes and wetlands (Lakes Lonsdale and Victoria). Also, stormwater drains from parts of Point Lonsdale and Queenscliff.

Eagle Rock Marine Sanctuary Eagle Rock Marine Sanctuary is in an open coast area, therefore direct impacts from surrounding catchments and rivers would be limited. However, included within the sanctuary is the tidal reach of the Painkalac Creek. Painkalac creek flows trough the township of Aireys Inlet that is inundated with tourists during holiday periods. Threats in the Painkalac Creek and associated catchments include stock access (agricultural and tourists), declining water quality, algal blooms, degraded riparian vegetation, stormwater inputs and urbanization. Artificial estuary openings are also a threat.

Barwon Bluff Marine Sanctuary Located at Barwon Heads in an open coast area and including the tidal reaches of the Barwon river. Threats in the Barwon Basin are numerous. However, there would be limited impacts from the river upon the sanctuary due to long shore drift.

-B9-


The Arches Marine Sanctuary This sanctuary is located 700m offshore of Port Campbell. May be influenced by Port Campbell Creek and possibly stormwater. However, any impacts or flows would be diluted.

Marengo Reefs Marine Sanctuary People will pose the largest impact on this sanctuary due to the large numbers of tourist that visit the area. Stormwater from Marengo township may have a limited effect.

Point Danger Marine Sanctuary Stormwater inputs pose the largest threat to this sanctuary, in an area known locally as “drainos”. B2.2 MANAGING THE THREATS To reduce the impacts from activities originating outside the management control of marine parks, strong partnership arrangements will be required between coastal and catchment managers. Partnership arrangements will include supporting catchment management projects, such as: • Construction of artificial wetlands, that reduce unnatural inputs into the marine

environment; • Arrangements for estuarine mouth openings; • Input to coastal and marine planning and policy instruments such as coastal

action plans and regional catchment strategies; and • Understanding interactions between catchment activities and coastal processes. A key objective of the Victorian Coastal Strategy (2002), to protect and improve the condition of estuarine biological diversity, will help address some of the threats to the estuaries within the Marine National Parks and Sanctuaries.

-B10-


Specific actions outlined in the strategy include: • Opportunities will be sought to provide adequate environmental flows to estuaries

through the Victorian Environmental Flows program; • A better understanding of ecological processes will be achieved key management

requirements of enclosed marine waters will be determined; • A strategic approach to protecting and improving the condition of coastal and

estuarine wetlands, including mangrove, seagrass and saltmarsh areas, will be developed;

• Best practice guidelines for the management of estuary mouth openings will be developed, incorporating environmental, social and economic issues.

B2.3 SPECIFIC ACTION/MANAGEMENT PLANS Specific management plans for each Marine Park and Sanctuary are currently in development. In addition to these plans, a number of other plans and strategies will be important namely: Port Phillip Heads Marine National Park • Swan Bay Catchment Action Plan 2002. • Borough of Queenscliff Stormwater Management Plan • City of Greater Geelong Stormwater Management Plan 12 Apostles Marine National Park • Gellibrand River Estuary and Wetland Management Plan 2001. Barwon Bluff Marine Sanctuary • Lake Connewarre Management Plan • City of Greater Geelong Stormwater Management Plan Eagle Rock Marine Sanctuary • Surf Coast Shire Stormwater Management Plan Point Danger Marine Sanctuary • Surf Coast Shire Stormwater Management Plan

-B11-


APPENDIX B3 – HERITAGE RIVERS In June 1987, the State government directed the Land Conservation Council (LCC) to conduct a special investigation of the scenic, recreational, cultural and ecological values of Victoria’s rivers and streams and to make recommendations on the use of these rivers and how their identified values can be protected. Seventeen “Victorian Heritage Rivers” were identified from the investigation as having outstanding values that required protection for current and future generations. A 35km reach (or corridor) of the Aire River from Hopetoun Falls Scenic Reserve to the ocean was one of the rivers identified, and the only one identified within the Corangamite Region. A key Statewide target of the Victorian River Health Strategy (2002) is for “all Heritage Rivers to be maintained at least to their current condition and their Heritage River values protected”. B3.1 AIRE RIVER The following information is taken from “Rivers and Streams Special Investigation: Final Recommendations, LCC (1991)” and provides validation for the inclusion of the Aire as a Heritage River. The Aire River: • drains one of the highest rainfall areas in the State • contains undisturbed corridors of native vegetation comprising mostly cool

temperate rainforest species • has high scenic landscape value through the gorge and in the estuary • includes several geomorphological and geological features of State significance,

namely: the gorge, a lake created by a landslip, and a structurally controlled meander

• is considered good habitat for trout in the upper reaches with some of the best wild trout waters in the lower reaches

• has an exceptionally large population of platypus • has a diverse native fish fauna, with 12 species recorded (2 listed as vulnerable,

3 potentially threatened and 1 indeterminate) • includes a popular scenic drive with good access at points for picnicking and

camping.

-B12-


B3.2 SPECIFIC RECOMMENDATIONS Based on the above, a number of recommendations were put forward to assist the protection of this valuable State asset. R1. That the corridor be retained free from impoundments, artificial barriers, or

structures that impede the passage of instream fauna R2. That any new diversions of water only be permitted if their volumes, timing, and

offtake do not significantly impair native fish habitat conditions, or reduce scenic landscape value

R3. That scenic landscapes from the commencement of the corridor to the mouth of the gorge, and below Lake Craven be protected

R4. That cool temperate rainforest along the corridor be protected R5. That Australian Grayling and Tasmanian Mudfish habitat be protected R6. That native fish diversity be protected R7. That geomorphological sites of significance be protected R8. That habitat for platypus be protected R9. That opportunities for trout fishing be protected R10. That other recreation activities continue where permitted in accordance with

land status R11. That arrangements necessary to protect the values of the estuary and

associated lakes, and reduce flood impacts on private land, be investigated For the purposes of the Corangamite River Health Strategy, these recommendations have been further clarified into a series of proposed actions as follows.
