Introduction This plan has been prepared by GHD Pty Ltd for the Lower Murray Darling Catchment Management Authority (LMD CMA), Darling Anabranch Environmental Flows (E-flows) Committee and the Darling Anabranch Project Steering Committee (DA PSC) to document; the previous management of the Darling Anabranch Lakes, current arrangements and make recommendations for future management. Future management for the purpose of this plan is related to the decision making process for regulators and structures in the event of a flood, where Anabranch Water (AW) is required to equitably partition water to lakes for the objective of providing economic benefits through lake bed cropping, restoring natural hydrological and ecological processes. This plan will be used by AW to operate lake regulators and structures and therefore requires formal endorsement by that body as well as relevant stakeholders and agencies, as described in Table 10. 31/22915/601562 Darling Anabranch Lakes Management Plan 1 2.

Assumptions Anabranch Water is the corporate name for the Board of Management of the Great Anabranch of the Darling River Private Water Supply and Irrigation District. Private water supply and irrigation districts such as this, are constituted under Division 2 of the Water Management Act 2000, and defined in the Act as Private Irrigation Districts (PID's). A PID may construct, maintain and operate water supply works on sites, which the Governor has authorised. The process of handing over responsibility from the Anabranch Water Trust to Anabranch Water will formalise the body that will be responsible for decision-making and regulator/structure operation under this plan. Therefore the body to be responsible for the future operation and maintenance of regulators/structures and hence water delivery decision-making to the Anabranch Lakes will be Anabranch Water. This management plan is reliant on the findings of processes and reports being developed in tandem. This document should be revised once the findings of the following processes and reports are finalised: » The Memorandum of Understanding for Nearie Lake (DECC); » Darling Anabranch Lakes Responsibility Plan (Arthur Latta); » Environmental Flows Implementation Plan (SKM); » Handover of the operation and maintenance of regulators from the Anabranch Water Trust to Anabranch Water; » Review of the cropping permit conditions for receding floodwater cropping (NSW Department of Lands); and » Adaptive Management Plan for DA Lakes (proposed by Darling Anabranch E-flows committee). 31/22915/601562 Darling Anabranch Lakes Management Plan 3 4. Purpose The purpose of this Anabranch Lakes Management Plan is to document the management of the Darling Anabranch Lake system’ s water, native vegetation and crop management practices that maintain or improve: » Environmental values; » Protect cultural values; » Economic resources; and » Social values. Previous management and decision-making processes of the Anabranch Lakes has not been formally documented. Decision-making was undertaken by individuals, acting in good faith for fair and equitable outcomes for lakebed croppers taking into account the recommendations from Jenkins and Briggs’ (1995) Guidelines on Lakebed Cropping. The aim of this plan is to document a transparent and practical process to ensure that the above values are maintained or improved. 31/22915/601562 Darling Anabranch Lakes Management Plan 4 5. Background The Greater Darling Anabranch is an ancestral channel of the Darling River, ephemeral in nature, which receives water from the Darling River when flows upstream of the Anabranch offtake exceed 10 000 ML/day or via Tandou and Redbank Creeks when flow passing Menindee exceeds 20 000 ML/day (Harriss et al 1991). The Lakes associated with the Darling Anabranch are therefore episodic wetlands, with varying wetting and drying cycles. There are 11 large lakes and several lesser lakes and wetlands which are connected at various levels and reaches of the Anabranch, having varying natural flooding patterns. Figure 1 outlines the location of major lakes of the Anabranch. Under natural conditions the Anabranch flowed about every two years out of three in the upper reaches and less frequently down stream (Irish 1992). About every two and a half years flows reached half way down the system (Withers 1994). The Darling Anabranch has, in the past serviced the stock and domestic water requirements of the adjoining farms. Replenishment flows in the order of 50 000 M/L were released annually from the Menindee Lakes system. During certain flood events, water was able to enter the lakes connected to the Anabranch and on private land where cultivation consents existed, crops were sown following the recession of floodwater. The role of the in-stream structures in aiding lake inundation by controlling water levels was reported in the Darling Anabranch Environmental Impact Statement (DA EIS) as minimal. Lakebed cropping commenced in the late 1950’ s, growing a variety of cereals, oil seeds and fodder crops dependant on the moisture content of the soil and the season when sowing conditions were suitable. Crops were generally sown when the lakebed was solid enough to support tractors. Due to the un-natural flow patterns and large system losses (47 000 ML, through evaporation and seepage) the Darling Anabranch Management Plan (DAMP) was developed to pipe the stock and domestic water requirements and re-instate more natural flows to the Anabranch (eg ephemeral rather than permanent) which included removing or modifying in-stream structures. The proposed implementation of the environmental flow regime flows will be documented in the Darling Anabranch Environmental Flows Implementation Plan (SKM 2008) and will assist the Department of Environment and Climate Change (DECC) and Department of Water and Energy (DWE) on the allocation of environmental water. 31/22915/601562 Darling Anabranch Lakes Management Plan 5 Tandou Tandou Creek Redbank Creek REDBANK LITTLE LAKES Darling Anabranch T Darling River CHINAMANS LAKE MINDONA POPILTAH AF POPIO LITTLE PINE BINJIE ROTTEN NIALIA YELTA NEARIE DR WINDAMINGLE TRAVELLERS WARRAWENIA THREE MILE NITCHIE LAKE MILKENGAY TOORA BULPUNGA Oakbank Murray River 1:500,000 0 5 10 20 Kilometres (at A3) Map Projection: Transverse Mercator Horizontal Datum: Geocentric Datum of Australia 1994 Grid: Map Grid of Australia, Zone 54 o LMD CMA Anabranch Lakes Management Plan Job Number Revision Date Anabranch Lakes Figure 1 Darling Anabranch Lakes G:\31\22915\CADD\GIS\Arcview © 31-22915 C 20 October 2008 2007.

With the establishment of Anabranch Water (PID), this body will be responsible for construction, operation and maintenance of the regulators/structures associated with the lakes. Anabranch Water will also have a management role in the distribution of floodwater to the lakes through agreement with agencies, under this Lake Plan. Table 1 outlines the various stakeholders associated with the Anabranch Lakes and the areas of interest and influence.

Previous Management of the Lakes and Lake Regulators Prior to the establishment of Anabranch Water, the Anabranch Water Trust was responsible for the management and decision-making associated with the Anabranch Lakes regulators / structures. The general principles adopted during the decision making process were taken from two reports, Guidelines for Managing Cropping on Lakes in the Murray-Darling Basin (Briggs & Jenkins 1997) and Ecological Management of Lakebed Cropping on the Lakes of the Great Anabranch of the Darling River (Jenkins & Briggs 1995). These principles as described by Keith Forster (2008, pers. comm.) include: » Lakes were to be fully inundated so that fringing native vegetation received water as well as the lakebeds; and » The sequential list was followed where complete inundation could be achieved. Figure 2 is a typical decision making process followed by the Anabranch Water Trust when a flood of sufficient magnitude was known to enter the Darling Anabranch and available for lake inundation. The flooding sequence of the Anabranch Lakes from 1970 to date is summarised in Table 2. To date 28 cropping permits exist over the lakes. 31/22915/601562 Darling Anabranch Lakes Management Plan 8 Anabranch Trust Notified of flood volume available. Equivalent of DWE From a list of previous flood events allocate water to lakes that are “next in line” Anabranch Water Trust Of those lakes that are “next in line” allocate water to those which, given the volumes available will fill Anabranch Water Trust Notify lake croppers of the allocation of water to their lake and expected timing of the flood. Anabranch Water Trust Regulators opened or block banks removed to allow flood-waters to enter lakes.

Values of the Anabranch Lakes The following chapter provides a brief overview of the values of the Anabranch Lakes, including ecological, indigenous, social and economic. The identification of values indicates the importance of the lakes due to the broad range of services they provide, be they for conservation, agricultural, cultural or visual amenity purposes. The focus of this chapter on the benefits provided by the lakes highlights the overall objective of this plan to protect and enhance the lakes to ensure that they are able to continue to provide a broad range of services into the future. These values should be the basis of an adaptive monitoring program. 8.1 Ecological Values1 Table 3 Flora species associated with the Anabranch Lakes Key to Table: EPBC Commonwealth Environment Protection and Biodiversity Conservation Act 1999 TSC Threatened Species Conservation Act 1995 Conservation Significance: CR Critically Endangered EN Endangered VU Vulnerable ** Introduced species % Species listed as threatened in NSW and/or Australia Threat Status Ephemeral Herbland Red Water Milfoil Myriophyllum sp.

the Anabranch), along the Anabranch itself, to as far north as Broken Hill and Lake Mungo. This occupation occurred for at least 47,000 years (Balme and Hope 1990). Cultural heritage sites that have been identified include open camps, middens, burials and stone arrangements. The majority of recorded archaeological evidence occurs around the lunettes of the lakes. In addition, models developed by Craib (Bonhomme Craib 2001) identified likely areas of Aboriginal significance were strongly associated with the presence of water (DAMP Steering Committee 2002). Local Aboriginal elders and other relevant community members were consulted during the development of the Darling Anabranch Environmental Impact Statement (EIS) to identify preliminary community views, assist in the planning of cultural heritage studies, and to participate in the field based assessments. Consultation revealed that the Barkindji group was particularly concerned about the preservation of Aboriginal archaeological sites. An Aboriginal Community Discussion Forum was held on 18th July 2008 as part of the Anabranch Environmental Flows Project. This meeting was an opportunity for the Barkindji Elders to discuss concerns about the management of the Anabranch. The only recorded reference to the Anabranch Lakes was concern expressed that inundating the lakes would reduce water in the Anabranch. Of importance to this project is the request made that Aboriginal representatives be engaged as site monitors during the construction phase of projects. This is of particular importance where block banks on lake beds are removed or modified. Where available reference to cultural heritage management protocols would assist in the communication and management of works in relation to Aboriginal Cultural Heritage(Earth Tech 2004). If any previously unidentified Aboriginal archaeological or historical cultural resources are encountered during the course of construction of infrastructure, all works likely to affect the material shall cease immediately and the Cultural Heritage Branch of the NSW Department of Environment and Climate Change (DECC), the Barkindji Elders, the Dareton or Menindee Local Aboriginal Land Councils, or the NSW Heritage Office consulted about an appropriate course of action prior to recommencement of work. 8.3 Social Values Many of the landholders are long-term residents who have been living in the Anabranch area for between 20 and 80 years. These landholders have a strong historical connection to the Anabranch, with some families having lived for generations in the area, in fact earlier generations of some families being the initial pioneers. (DAMP Steering Committee 2002). The Anabranch and the lakes are also a place for visitors, including bird watchers, fishing, bushwalking, camping and creating art. Although Nearie Lake Nature Reserve is not a National Park and is therefore not established for visitation it can be utilised for scientific and educational purposes. During the development of the Darling Anabranch EIS landholders were consulted on issues pertaining to social, environmental, economic and water and property rights (EarthTech 2004). During the development of this plan landholders have been involved through representation on the Environmental Flows Steering Committee by lakebed croppers. Lakebed croppers were involved in a workshop in July 2008. This was an opportunity for them to gain an understanding of the development of this management plan and raise concerns. The plan has also been distributed to representatives of the lakebed croppers for comment. 31/22915/601562 Darling Anabranch Lakes Management Plan 18 8.4 Economic Values The Darling Anabranch Lakes provide the opportunity for cropping following receding floodwaters. This method of farming is by definition, opportunistic and therefore not the primary income landholders rely on from their farming enterprise. However, lakebed cropping can provide a lucrative income when the opportunity arises. An economic survey conducted by Thomsons Advisers (1999) found that total income from the 30 respondents showed productivity from non-lakebed farming ranged from nearly $2.5 million in 1994 to $4 million in 1996. This can be compared against the Lake Bed cropping that occurred in 1998 which generated a total of around $4 million (DAMP Steering Committee 2002). 31/22915/601562 Darling Anabranch Lakes Management Plan 19 9. Overview of Lakebed Cropping and Regulators In the Darling Anabranch system, 25 receding floodwater cropping permits currently exist over 14 lakes which equates to 26 294ha of potential cropped area. The NSW Department of Lands is currently reviewing these permits and associated conditions, including those permits that are due for renewal and those which have an indefinite status. NSW Lands has referred these conditions to the Department of Primary Industries (DPI), DECC, the Lakebed Croppers and the Lower Murray Darling CMA for comment. Through the review of the permits and conditions, these agencies have an opportunity to influence the management of lakebed cropping. When finalised, these conditions should be included as an addendum to this management plan as particular cropping practices are an important component of ecologically sustainable lake management. 9.1 Sustainable Practices for Opportunistic Cropping Sustainable cropping practices for lakebed cropping have been documented by Jenkins and Briggs in 1995 and no further documents to date have been produced to supersede this. Given the lack of a recent update to this report, the Jenkins and Briggs 1995 report will be the basis for establishing ecological cropping guidelines along with the current and revised cropping permit conditions. The principles of sustainable lakebed cropping identified by Jenkins and Briggs (1995) are generally practiced by Anabranch Lake croppers, however it should be noted that these are guidelines only and do not form part of lake cropper’ s permits. The general principles of lakebed cropping identified by Briggs and the current practices are compared in Table 8. Table 8 Comparison of cropping practices between Briggs recommendations and current permit conditions and Proposed Conditions Recommended By Jenkins and Briggs 1995 Example of recent cropping consent conditions Proposed Conditions Cropping is usually undertaken without fertilizers, pesticides or herbicides Products based on Chlorsulfuron, Dicamba, Picloram, 2,4,D Diuron or Atrazine or any product not registered for the specific purpose in terms of the Pesticides Act 1978 shall not be used to control weeds in winter crops. Some locust pesticides have been used in the past. Process for licencing of chemical use on individual basis. NASAA (DECC) and APVMA list to be the basis and anything outside that to be licenced. Some lakes carry an organic accreditation. Others are grown organically but do not have the formal accreditation. NB. Tests have found chemical residue in soils possibly from the water not application by croppers. Crops are not planted annually. 31/22915/601562 Permits are for cultivation on Darling Anabranch Lakes Management Plan Flood or rainfall that inundates a 20 Recommended By Jenkins and Briggs 1995 Only following receding floodwaters when the soil moisture level is optimum and timing is right for sowing. Example of recent cropping consent conditions receding floodwaters. Proposed Conditions Sowing of multiple crops following rainfall is not recommended. Cultivation is granted on soil moisture resulting from receding floodwaters. Separate consents are required for dryland or irrigation. Sowing of successive crops following rainfall is not recommended. Lakes should be allowed to return to their vegetated state following harvest rather than bare fallowed. Retention of native vegetation as a source of seed for revegetation is to be maintained. Stubble is to be retained except with the approval of the Commissioner. Lakes should be allowed to return to their vegetated state following harvest rather than bare fallowed. Cropping does not prevent the natural flooding and drying process. Not specified Regulator management not to prevent natural flooding and drying process Trees are not cleared prior to cropping, although shrubs may be. Areas carrying stands of bladder salt bush, old man saltbush, cotton saltbush, Mitchell grass or copper clover shall be left uncultivated for a distance of at least 100m around any stand in which plants are spaced at 20m or less apart. As per the Native Vegetation Act. Minimise grazing following a crop to allow for regeneration and minimise soil compaction. Not specified Requires a measurable stocking rate, frequency and duration as per Western Lands Act. A strip of native vegetation should be retained on the edge of the lake between the tree line and the lake bed as well as patches within the lakes. An uncultivated perimeter of 100m is to be permanently retained. Lakes will have permits part of mapped by Lands as part of permit review based on Briggs and the Native Vegetation Act. All lakes to have at least 5% of the central part of the lake uncropped. Not specified 9.2 lake for more than 4 weeks. Removal of stubble (burning) is to be by permission of the Commissioner. Need a measurable amount. Current Status of the Regulators and Infrastructure The Water Supply Act 1912 gives Anabranch Water Trust the operation of water supply within their Trust Boundary. Lakebed structures would be works that qualify as "water supply works" as described in the WM Act, and consequently can be works of Anabranch Water (AW). There are no operational rules in the WM Act 31/22915/601562 Darling Anabranch Lakes Management Plan 21 describing how AW should operate its structures. Internal operations are left to AW. The use of AW works as control structures for containment of environmental flows (E-flows) is outside usual AW operations. The operation of structures for containment of E-flows will not depend on the legislation, but rather on a written agreement between AW and whoever the controlling body is to achieve the E-flow outcomes. AW will control the structures into the feeder channels to the many lakes, which are naturally filled from higher flows. All of the structures in the bed of the Anabranch are scheduled to be removed as part of the plan to release E-flows down the Anabranch, and to allow a more natural flow regime to re-establish. The remaining works are those designed to control flows into and out of the lakes. These works are to remain, as they are important not only in their role of controlling higher flows, but in some cases as essential tools for keeping environmental flows within the main bed of the Anabranch (Latta 2008 in prep). AW will control these lakebed structures on the feeder channels to the lakes. 9.3 Current Opportunistic Cropping Status and Permit Conditions Consent to cultivate within the bed of the Anabranch lakes occurs under the condition that the cropping takes place following the recession of floodwaters. The area, in hectares to be cultivated, is specified on the cultivation consent as well as general configuration of the actual cultivated area. These conditions are currently being reviewed by the Department of Lands who have referred the permits to DECC, DPI and the Lower Murray Darling CMA for comment. The results of this review and the changes to cropping permit conditions are an important component of lake management. These conditions will be an addendum to this management plan once finalised. 9.4 Hydrology of the Anabranch and Lakes The Anabranch Lakes experience a highly variable water regime, where the lakes may be flooded for months to years and then remain dry for months to decades prior to re-wetting. The following is a summary of the hydrology contained in the Darling Anabranch EIS-Appendix F; Flow Modelling Assessment (2004). 9.4.1 Natural Condition Flows - Return Intervals and Timing » Inflow to the Darling Anabranch from the Darling River have occurred at flows of approximately 10 000 ML/day measured at Menindee, with an average recurrence interval of 2 to 3 years; Inflows into the channel sufficient to reach half-way down the actual Anabranch channel occurs approximately every to years; » Based on anecdotal evidence, lakes located midway along the Anabranch received flooding every 7 to 15 years. End of system flows into the Murray River occur less frequently, at about once every 15 years (EIS, Appendix H); » Only in major floods did a significant volume of water reach the Murray River via the Anabranch, with water flowing the full length of the Anabranch to the Murray River only nine times during the period 1890 to 1961 and Lake Nearie flooding about one in 10 to 15 years; and » Timing of flows in the Anabranch depends on flows in the Darling River floods in February to April generally result from summer rainfalls in tributaries in southern Queensland, while those in July and August result from winter rainfall in central and north-eastern NSW. 31/22915/601562 Darling Anabranch Lakes Management Plan 22 9.4.2 Flow Conditions Prior to the Pipeline » Prior to construction of the Anabranch Pipeline up to 50 000 ML of water was released annually to replenish weir pools in the Anabranch for stock and domestic purposes. Releases were made at a rate of approximately 500 ML/day for a period of 100 days; » It is however noted that only an estimated 3000 ML was used for stock and domestic purposes, with the rest being lost to evaporation, transmission losses, seepage and the environment (fringing native vegetation); » The development of regulator banks and by-wash banks across the Anabranch flow paths increase the volume, depth and duration of water that could be held within the Anabranch (and consequently area inundated) during no-flow periods; and » Prior to 1980, replenishment flows typically commenced in May. Post ~1980 replenishment flows have been made in Spring to provide a more reliable water supply and better water quality during the major Summer demand period (Withers, 1994, as cited in EIS Appendix F). 9.4.3 Predicted flows post structure removal and modification Hydraulic modelling (HEC-RAS) undertaken by the NSW Department of Environment and Climate Change (DECC) considered two scenarios: » The existing Anabranch system with the 25 block bank structures and hence in-stream weir pools; and » Proposed modification (to 3 structures) and removal of (15 in-stream block bank) structures to allow the free passage of environmental flows and taking into account preliminary basic designs to cater for fish passage. The results of the HEC-RAS modelling demonstrate the impact of modification of structures within the Anabranch on modelled water levels in the Anabranch. The following general conclusions have been made from the HEC-RAS results: » Modification and removal of the structures generally results in a drop in water levels; » The impact of the structures on water levels are more pronounced for lower flow rates (500 and 800 ML/d) than the high flow rate (2000 ML/d); » Additional findings were that flows exceeding 570 ML/d exceeded the river banks in some isolated areas and flows of 2000 ML/d exceeded the river banks in all areas; and » Currently there are no models suitable to predict the water volumes required to commence to flood individual lakes. 31/22915/601562 Darling Anabranch Lakes Management Plan 23 10.

Details of this legislation are in Appendix D. 31/22915/601562 Darling Anabranch Lakes Management Plan 24 11. Flood Management Interactions with Environmental Flows (E-flows) As part of the Living Murray Initiative, the supply of stock and domestic entitlements (3,000 ML) will be made via a pipeline instead of replenishment flows along the Anabranch. This is expected to save approximately 47 GL pa. The water savings will be utilised to provide an environmental flow regime to the Anabranch that more closely mimics the natural ephemeral flow regime. It is suggested that this will require approximately 60 – 75 GL per release with an average two-year frequency over a 10-year cycle when water is available. It would be deemed desirable that each environmental flow event aimed to deliver stream flows into the Murray River at the end of the system. The proposed implementation of environmental flows within the Anabranch channel will be documented in the Darling Anabranch Environmental Flows Implementation Plan (SKM 2008 in prep). At this stage, E-flows are designated to be confined within the Anabranch Channel and may not be used for ecological outcomes in the lakes. The flow volumes planned for release for E-flows are not considered to be high enough to enter the lakes, however, the lake regulators are still to be closed to prevent E-flows entering the lakes. There is potential for E-flows to “piggy back”on a flood event. The difference in the volume of water in the system allocated as E-flows and that which is “flood”water would require definition so that only floodwater entered lakes. This will require careful consideration and communication between the E-flows committee and AW responsible for lake regulators to ensure that water is both optimised for environmental purposes and the opportunity given by lake inundation for cropping. A future consideration, which requires further investigation is the use of E-flows for ecological outcomes in the lakes. The following factors will need to be considered if and when there is surplus E-flows water available and the E-flows Committee or DECC deems it appropriate to allocate water to the lakes: » A documented position held by Anabranch Water on the allocation of water to lakes; » An understanding of the current ecological condition of the lakes; » An understanding of the natural hydrological processes of the lakes; » Ecological objectives for the lakes; » Prioritisation of the lakes to receive flows based on ecological values; » An agreement with the E-flows Committee on the conditions under which E-flows should enter a lake; » Agreement from lake landholders on those conditions; and » Any other identified considerations, which are deemed necessary. It should be noted that the potential for E-flows to “piggy back”on a flood event and use of flood water to enter the lakes largely depends on commence to flow levels of the respective lakes. Although general information was available regarding previous inundations of the lakes, commence to flow information was not readily available. This presents a serious limitation in being able to estimate or predict the flows required to inundate the individual lakes. 31/22915/601562 Darling Anabranch Lakes Management Plan 25 12. Nearie Lake 12.1 Nearie Lake Values Nearie Lake was dedicated as a Nature Reserve in 1973 following its expiration as part of a Western Lands Commission Pastoral Lease. It is the only wetland nature reserve along the Anabranch (DECC 2008). Under the NPW Act 1974, nature reserves are managed to: » Conserve biodiversity, maintain ecosystem functions, and protect geological and geomorphological features and natural phenomena; » Conserve places, objects, features and landscapes of cultural value; » Promote public appreciation, enjoyment and understanding of the reserve’ s natural and cultural values; and » Provide for appropriate research and monitoring. In addition to those general management objectives the following specific objectives apply to Nearie Lake Nature Reserve: » The protection and restoration of natural river flows in the Great Darling Anabranch and Darling River systems; » To maintain as far as possible natural flow regimes in and out of the lake to protect wetlands and waterbird breeding areas in the reserve; » The protection of aquatic and terrestrial plants and animals; » The protection of Aboriginal burial sites and potential megafauna sites; and » The provision of opportunities for scientific research and environmental education use which are compatible with the conservation of the area (NPWS, 2006). 12.2 Memorandum of Understanding A Memorandum of Understanding for Nearie Lake was first established in 1995 to document the preferred management of Nearie Lake for ecological purposes. This MoU is currently being revised by the DECC in light of the expected changes to hydrology resulting from the changes from replenishment flows to E-flows. The draft revised MoU outlines the principles for water management of Nearie Lake according to the type of flows (environmental, surplus, local rainfall on environmental flows and floods) down the Anabranch. The MoU requests that Anabranch Water liaise with DECC when a flood event is expected. Nearie Lake land managers have requested, as with all the lake land managers, that they be consulted during the decision making process of regulator operation in the event of a flood. The principles of the MoU can then be applied by DECC and Anabranch Water to decide if it is appropriate to allow water into Nearie Lake. 31/22915/601562 Darling Anabranch Lakes Management Plan 26 13. Lakes Management Plan Monitoring and Review An Adaptive Management Monitoring Plan for the Darling Anabranch has been completed (Wallace et al 2007). This plan addresses the ecological objectives of the Anabranch channel and environmental flows and does not address the Anabranch Lakes. As suggested in the Darling Anabranch AMMP, it could be expanded upon to include the Anabranch Lakes. This would also function to set ecological objectives and bring more rigour to the decision-making process. The plan should be reviewed after every major event. In addition to the ecological parameters identified in the Darling Anabranch AMMP, other monitoring specific to the Anabranch Lakes and floodplain could include: » Cropping; » Water quality; and » Hydrology. 13.1 Cropping Specific parameters recommended for monitoring include: » Crop yields; » Crop type; » % Protein of yields; » Chemical use; » Amount of cultivations; » Area sown. 13.2 Water Quality » Water Quality Entering Lakes; » Water Quality Exiting Lakes. 13.3 Hydrology As earlier indicated, results of the hydraulic modelling indicate that modification and removal of the structures will generally result in a reduced water levels in the Anabranch. It is therefore important that a monitoring program be considered to monitor flood levels and flows during flood events in order to improve decision-making on system operation and management of future flood events. Where possible, monitoring should be undertaken on both the Darling Anabranch and the lakes to improve understanding of the interaction between flows in the Anabranch and inundation of the lakes under the changed conditions. 31/22915/601562 Darling Anabranch Lakes Management Plan 27 13.4 Review The Lakes Management Plan should be reviewed following any flow or flood event. This needs to be done to facilitate the inclusion of any appropriate amendments to account for any changes in priorities for future environmental watering events. 31/22915/601562 Darling Anabranch Lakes Management Plan 28 14. General Recommendations The following recommendations relate to the considerations and future information required to improve decision making in the management of the Anabranch Lakes as well as; Current Considerations » Structures/regulators to remain open for the "normal duration", defined as the time taken to allow floodwater in and then out so that fish that may have entered the lake with the inflowing water are given a cue to move back to the anabranch and avoid stranding. » Inform each relevant agency of planned lake inundation so that opportunistic monitoring can take place where possible (DPI, MDFRC, DECC, State Water etc). » The prioritisation of lakes, where feasible to be based on historical allocations so that water is delivered equitably for economic opportunities and environmental outcomes. » It needs to be recognised that before regulation the upper lakes were to likely have more frequent opportunities which is the natural sequence. Provisions will need to be made to equitably consider all lakes. » Unable to change priority from history of inundation until a Monitoring Program for the Lakes is established. This will then require the Lakes Management Plan to be re-addressed to include the Adaptive Management of the Lakes as part of the prioritising decision-making. » Prioritisation using the Adaptive Management Program will require joint by an Environmental Flows Committee (Lakes Adaptive Management Committee) including representatives from AW, E-flows Committee and other stakeholders, to facilitate joint decision-making. Decisions will be made on an ecological basis with consideration to the potential of economic / social losses that may result. Information Gaps » Monitoring of flood levels in the Anabranch channel and lakes to gain information. » Development of a hydraulic model of the commence to flows for the Anabranch Lakes. 31/22915/601562 Darling Anabranch Lakes Management Plan 29 15. Future Decision Making Institutional Arrangements 15.1 Decision Making Triggers The requirement for a regulatory body to make recommendations to DWE about which lakes to flood are likely to only occur in flood events. Table 10 lists the main flow events and the responsible agency. Table 10 Anabranch flows and Responsibility for Water Management Type of Flow Event Organisation Responsible In Consultation Major Flood Event DWE Anabranch Water Murray Darling Basin Commission (When water is still available after all anabranches are full) State Water Anabranch Water Medium Flood Event DPI (When water is available over and above an environmental flow, but not likely to be sufficient to fill all the lakes). Environmental Flow DECC DWE Environmental Flows Committee Lakebed Croppers MDBC State Water DECC Anabranch Water DPI (Water for adaptive environmental management, which generally stays within the Channel). DWE Environmental Flows Committee LMD CMA In addition, during major flood events it is likely that all the lakes will be flooded, so therefore no decision on which lakes to flood would be required. Hence, recommendations are only likely to be required in minor flood events where there is insufficient water for all lakes to be flooded. The constitution of Anabranch Water enables the Board of Management to determine the quantity of water to be supplied to lakes for the purposes of lakebed cropping and environmental outcomes. It is suggested that the water management arrangements for Anabranch Water should cover the following provisions: » Decision making objectives; » Decision making responsibilities and processes; and 31/22915/601562 Darling Anabranch Lakes Management Plan 30 » Considerations in prioritising which lakes to fill. 15.2 Decision Making Objectives It is suggested that the following objectives be adopted by Anabranch Water Board for the lakebed flooding: » Seek to enhance economic, environmental and social outcomes. » Aim to achieve an equitable and transparent sharing of water to flood lakebeds over time; » Anabranch Water to assist landholders in planning by providing information on the rotation of lakes for flooding as early as possible. 15.3 Decision Making Responsibilities and Processes Once the predicted amount of available water has been notified to Anabranch Water by DWE/State Water, the decision as to what water is allocated to which lakes should be made by the Board chairman, in consultation with the General Manager of AW, if time permits. During the actual filling process, when decisions often have to be made in a very short time-frame (often within the hour) these decisions should be made by the Chairman, or his appointee. Decisions made should be documented, and if considered necessary by the Board, ratified at its next meeting. 15.4 Lakes to Filling Rotational Order In determining which lakes to flood it is recommended that the following process be adopted. 1. Categorise lakes into priorities for the next flood event. Categorisation of the lakes should be based on the history of flooding of the lakes. The basis of this approach is that the first priority should be the requirements of getting water to those lakes that have had the least watering. By giving priority to those that have received the least flooding will overtime maintain economic, environmental and social equity between the lakes. Lakebed flooding provides considerable economic opportunities for those who have access to the lakebed for cropping. As such, it is considered that access to previously flooded lakebeds should be shared over time It is suggested that high priority lakes (these inundated the least) be flooded first, followed by medium and low priority lakes. This categorising will need to be updated after each flood event and is considered to be a function that Anabranch Water be responsible to undertake this priority listing as soon as possible after an event. The priority listing should be made available to stakeholders such as the Environmental Flow Committee, other agencies and Lake Bed Croppers. 31/22915/601562 Darling Anabranch Lakes Management Plan 31 2 Seek advice from DECC on the quantity of available water for flooding of lakes and then determine which lakes are to be flooded. This will also require information on the flow volumes required to have water enter each lake. The volume of water, which may be a flood event or a flood “piggy backing”an environmental flow will be a critical factor in the ability for water to enter some lakes. Should insufficient water be available to flood all the lakes in a priority category, it is preferable that the residual water may be used to fully inundate one or more smaller lakes in a lower priority category. Therefore, the following factors should be taken into account when determining which lakes to flood in a priority category: » The ability for water to be delivered into particular lakes given the planned flow regimes and existing infrastructure at the various lakes. » The available water for lakebed flooding and the capacity of lakes to be flooded, so that all the lakes to be flooded are completely rather than partially inundated An example of the coarse filter that could be applied is presented in Figure 3. Information critical to applying this filter is prioritisation of lakes, quantum of water available and the required flow regime to have water enter a lake. 3 As part of a future refinement to the Lake Management Plan an adaptive management monitoring program should be incorporated which will assist to define ecological objectives (if available) for watering of lakes. With the development of a Lake Adaptive Management Monitoring Program (AMMP), Anabranch Water and the Environmental Flows Committee should consider all information available when developing the Priority lists. As with the AMMP for the Darling Anabranch channel a similar lake plan will set parameters for monitoring the baseline condition of the lakes and the implementation of this management plan. The data collected (ie. water quality, flora, fauna, soils, crop statistics) will provide a sound basis for decisionmaking which maintains or improves the ecological condition of the lakes and sustainable cropping practices. If an adaptive management monitoring program is developed for the Anabranch Lakes, that this Lakes Management Plan gets reviewed by suitable stakeholders and accordingly amended. 31/22915/601562 Darling Anabranch Lakes Management Plan 32 If Yes If Yes If Yes Figure 3 Coarse Filter for Allocations of Flood Water to Anabranch Lakes. 16. Conclusion The two-step process outlined in Section 15.3 provides Anabranch Water and the Environmental Flows Committee with a sound, documented approach to a lakebed flood that meets the decision-making objectives in Section 15.2. The process: » Seeks to enhance environmental, economical and social outcomes by prioritising lakes based on documented historical inundation linked to an Adaptive Management Monitoring Program. » Aims to achieve an equitable sharing of access to flood water for lakebed cropping and environmental purposes over time through consideration of the history of flooding; » Provides a transparent process for decision making in terms of which lakes get flooded; and » Assists landholders in planning by providing information of this flooding regime on the priority of lakes for flooding. 31/22915/601562 Darling Anabranch Lakes Management Plan 34 17.

Framework 31/22915/601562 Darling Anabranch Lakes Management Plan Commonwealth legislation (Australia) Environment Protection and Biodiversity Conservation Act 1999 The primary objective of the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) is to “provide for the protection of the environment, especially those aspects of the environment that are matters of national environmental significance”. Environmental approvals under the EPBC Act may be required for an “action”that has, will have or that is likely to have a significant impact on: (a) Matters of national environmental significance (known as ‘ NES matters’ ); or (b) The environment on Commonwealth land (whether or not the action is occurring on Commonwealth land). Approval for such an action may be required from the Commonwealth Minister for Environment and Water Resources. An “action”is considered to include a project, development, undertaking, activity or series of activities. NES matters include: » World Heritage Areas; » National Heritage Places; » Ramsar wetlands of international importance; » Nationally listed threatened species and ecological communities; » Listed migratory species; » Nuclear actions; and » Commonwealth marine areas. Several species of commonwealth threatened fauna including, Australian Painted Snipe (Rostratula australis), Black-eared Miner (Manorina melanotis), Regent Parrot (Polytelis anthopeplus) and Greater Long-eared Bat (Nyctophilus timoriensis) may utilise habitats in association with or in the vicinity of the Anabranch lakes. Various flora species, including the Menindee Nightshade (Solanum karsense) have been recorded from the Anabranch lakes and may persist throughout the lakes system. Various construction works that may be planned in association with the Anabranch lakes (e.g. construction of levees, regulators etc) should be assessed to clarify any potential issues in relation to the EPBC Act (i.e. significant impacts to NES matters). Depending upon the findings of environmental assessments, various works proposals may need to be referred to the Department of Environment, Heritage, Water and the Arts for approval by the minister. State Environmental Planning and Assessment Act, 1979 Background All development in NSW is assessed in accordance with the provisions of the Environmental Planning & Assessment Act 1979 (EP&A Act) and Environmental Planning and Assessment Regulation 2000 (the Regulation). The EP&A Act institutes a system for environmental planning and assessment, including 31/22915/601562 Darling Anabranch Lakes Management Plan approvals and environmental impact assessment. Implementation of the EP&A Act is the responsibility of the Minister for Planning, statutory authorities and local councils. The EP&A Act contains three schemes which impose requirements for planning approval: » Part 3A provides for control of ‘ major infrastructure or other projects’that require development consent or other approval from the Minister for Planning; » Part 4 provides for control of ‘ local development’that requires development consent from the local Council; and » Part 5 provides for control of ‘ activities’that do not require development consent or approval from the Minister for Planning. The need or otherwise for development consent is set out in environmental planning instruments – State Environmental Planning Policies (SEPP), Regional Environmental Plans (REP) or Local Environmental Plans (LEP). In regard to on-ground works (e.g. construction of regulators, block banks, levees) for flow management in conjunction with the Anabranch lakes, each scenario would need to be examined to assess which part of the EP&A Act the works fall under. Section 111 of the EP&A Act contains the duty of determining authorities to consider the environmental impacts of an activity. When considering an activity, the determining authority is required to “examine and take into account to the fullest extent possible all matters affecting or likely to affect the environment”. Section 112 of the EP&A Act requires the determining authority to consider whether the project is “likely to significantly affect the environment”(including critical habitat) or threatened species, populations or ecological communities, or their habitats. If the determining authority decides the project would be likely to significantly affect the environment it must obtain and consider an environmental impact statement (EIS). Further, if the project would be carried out on land that is critical habitat, or if the determining authority decides the project would be likely to significantly affect a threatened species, population, an ecological community or its habitat then it must obtain and consider a Species Impact Statement (SIS). Under Section 79C of the EP&A Act an assessment may need to be undertaken to decide whether there is likely to be a significant effect on threatened species, populations or ecological communities, or their habitats (‘ Assessment of Significance’or ‘ seven-part test of significance’ ). This test must be undertaken to determine the impact of a proposed development or activity on threatened species, populations or ecological communities (as listed on the schedules of the TSC Act 1995). A seven-part test of significance incorporates the following key questions: » A) In the case of a threatened species, whether the action proposed is likely to have an adverse effect on the life cycle of the species such that a viable local population of the species is likely to be placed at risk of extinction; » B) In the case of an endangered population, whether the action proposed is likely to have an adverse effect on the life cycle of the species that constitutes the endangered population such that a viable local population of the species is likely to be placed at risk of extinction; 31/22915/601562 Darling Anabranch Lakes Management Plan » C) In the case of an endangered ecological community or critically endangered ecological community, whether the action proposed: – (i) Is likely to have an adverse effect on the extent of the ecological community such that its local occurrence is likely to be placed at risk of extinction; or – (ii) Is likely to substantially and adversely modify the composition of the ecological community such that its local occurrence is likely to be placed at risk of extinction; » D) In relation to the habitat of a threatened species, population or ecological community: – (i) The extent to which habitat is likely to be removed or modified as a result of the action proposed; and – (ii) Whether an area of habitat is likely to become fragmented or isolated from other areas of habitat as a result of the proposed action; and – (iii) The importance of the habitat to be removed, modified, fragmented or isolated to the long-term survival of the species, population or ecological community in the locality; » E) Whether the action proposed is likely to have an adverse effect on critical habitat (either directly or indirectly); » F) Whether the action proposed is consistent with the objectives or actions of a recovery plan or threat abatement plan; » G) Whether the action proposed constitutes or is part of a key threatening process or is likely to result in the operation of, or increase the impact of, a key threatening process. The ‘ seven-part test’may need to be considered for proposed works in conjunction with the Anabranch lakes, depending upon which part of the EP&A Act the development falls. Any future construction works (e.g. levees, block-banks, regulators) proposed for any of the Anabranch lakes will need to be assessed to determine which part of the EP&A Act is applicable, which in turn will determine the level of assessment and relevant referral authority to assist in the approvals process. Obligations under Section 79C of the EP&A Act will be clarified once the scheme that the development falls under has been determined. State Environmental Planning Policies State Environmental Planning Policy (Major Projects) State Environmental Planning Policy (Major Projects) 2005 identifies development that is subject to Part 3A of the EP&A Act and requires the consent of the Minister. Each development proposal would need to be assessed to determine the scheme that is relevant to the project and therefore determine whether the proposal constitutes a major project. State Environmental Planning Policy No. 44 – Koala Habitat Protection SEPP 44 aims to encourage the proper conservation and management of areas of natural vegetation that provide habitat for koalas. According to SEPP 44, it is necessary to determine whether the sites provide ‘ potential koala habitat’or ‘ core koala habitat’ . SEPP 44 will need to be considered in the following situations: » The Wentworth LGA is listed in Schedule 1 of the SEPP as one of the local government areas that must be considered under SEPP 44; 31/22915/601562 Darling Anabranch Lakes Management Plan » If vegetation removal is considered at any stage due to proposed works in relation to the Anabranch lakes; » If one of more of the feed trees listed in Schedule 2 of SEPP 44 may be present (e.g. River Red Gums); and » The sites are greater than one hectare in area (regardless of the size of the potential disturbance). This assessment of koala habitat should therefore be undertaken, even though there have been no recent documented Koala records from the LMD CMA area, nor is it predicted to occur 4. To meet the requirements of SEPP 44: Potential koala habitat occurs if the total number of listed koala food trees in the upper and/or lower strata comprises greater than 15% of the total number of all trees (as listed in Schedule 2 of SEPP 44). Core koala habitat occurs can occur where there is a known population, a breeding population or a historically known population. In the case that potential koala habitat may be suspected, the following should occur: 1. The presence or absence of listed koala feed trees within a proposed development area should be established. – a) If absent, no further assessment is required. – b) If present, and clearly comprising greater than 15% of the trees, the presence of core koala habitat will need to be determined. (go to 3.) – c) If present, but it is uncertain if the trees comprise more or less than 15%, then samples of tree density will be required (go to 2.) 2. The percentage of koala feed trees within a proposal footprint will need to be determined by the use of transects. At least two linear transects of 250 m length and 10 metres width should be established across the site. The percentage of listed koala feed trees should then be calculated. – a) If less than 15% of the total trees are listed feed trees, then no further assessment is required. – b) If more than 15% of the total trees are listed feed trees, then the presence of core koala habitat will need to be determined (go to 3). 3. At sites where there is potential koala habitat present, the presence of core koala habitat will need to be determined. At each site, an appropriate number of sample areas will need to be intensively surveyed. Within each sample area, at least 20 listed feed trees should be included. At the base of each feed tree, searches should be conducted for koala scats. The trunks of each feed tree should also be viewed for the presence of koala scratches. Any sightings of koalas should also be noted. – a) If any evidence of koalas were found at a site (particularly breeding females), then it would probably be considered core habitat. – b) If no evidence of koalas were found at a site, then it would probably not be considered core habitat (given that there have been no historical records from the LMD CMA region). 4 Accessed from the DECC internet site on 11 June 2008 http://www.threatenedspecies.environment.nsw.gov.au/tsprofile/cma_list.aspx?name=Lower+Murray/Darling 31/22915/601562 Darling Anabranch Lakes Management Plan Development proposals in relation to the Anabranch Lakes (e.g. levees, block-banks, regulators), would need to be assessed to determine the presence of listed koala feed trees (e.g. River Red Gum Eucalyptus camaldulensis) and if present whether ‘ potential koala habitat’(and possibly ‘ core koala habitat’ ) is present. Once this has been determined, potential impacts to koala habitat (if present) will need to be established and managed. State environmental legislation Water Management Act 2000 The Water Management Act 2000 (WM Act) is administered by the Department of Water and Energy (DWE) (previously DNR). The WM Act replaces the Water Act 1912 in systems where a Water Sharing Plan is developed and implemented (although some parts of the Water Act 1912 remain in operation including licensing and permit provisions). The Anabranch lakes may be located within the Regulated Darling River Water Source. Any Water Supply Works located within a water source require an approval. A water supply work is defined as: » A) A work (such as a water pump or water bore) that is constructed or used for the purpose of taking water from a water source, or » B) A work (such as a tank or dam) that is constructed or used for the purpose of: – (i) Capturing or storing rainwater run-off, or – (ii) Storing water taken from a water source, or » C) A work (such as a water pipe or irrigation channel) that is constructed or used for the purpose of conveying water to the point at which it is to be used, or » D) Any work (such as a bank or levee) that has the effect of diverting away from a water source any overflow from the water source, or » E) Any work (such as a weir) that has the effect of impounding water in a water source, – Including a reticulated system of such works, and includes all associated pipes, sluices, valves and equipment, but does not include: » F) Any work (other than a water supply work under the control or management of the Sydney Water Corporation, the Hunter Water Corporation or a local water utility) that receives water from a water supply work under the control or management of the Sydney Water Corporation, the Hunter Water Corporation or a local water utility, or » G) Any work declared by the regulations not to be a water supply work. A water supply work approval authorises its holder to construct and use a specified water supply work at a specified location. Possible future works in association with the Anabranch Lakes could be considered water supply works due to the: » Possible storage of water from a water source (via levee, block-bank, regulator during inundation). A water supply work approval authorises its holder to construct and use a specified water supply work at a specified location. 31/22915/601562 Darling Anabranch Lakes Management Plan It is likely that proposed future works in relation to the Anabranch Lakes will require a water supply work approval under the Water Management Act 2000. The DWE should be contacted for advice in relation to the requirements under this act for all future proposed works. Crown Lands Act 1989 The Crown Lands Act 1989 is administered by the Department of Lands. Section 6 of the Crown Lands Act states that Crown land shall not be occupied, used, sold, leased, licensed, dedicated or reserved or otherwise dealt with unless the occupation, use, sale, lease, licence, reservation or dedication or other dealing is authorised by this Act or the Crown Lands (Continued Tenures) Act 1989. The Department of Lands should be contacted for each project proposal to determine whether a licence or letter of approval will be required under the Crown Lands Act 1989 for any new land use or possibly new structure proposed for the Anabranch Lakes. Fisheries Management Act 1994 The objectives of the Fisheries Management Act 1994 (FM Act) are to conserve, develop and share the fishery resources of the State for the benefit of present and future generations. Possible future works in relation to the Anabranch Lakes (e.g. levees, block-banks, regulators) may involve works associated with the removal of the existing structures and installation of new structures which may require some excavation or removal of material from water land (being wetlands that are intermittently submerged by water). Therefore, future works may be classified as dredging or reclamation under the FM Act. Section 200 of the FM Act states that a local government authority must not carry out dredging or reclamation work except under the authority of a permit issued by the Minister. However this section does not apply to work authorised under the Crown Lands Act 1989, or work authorised by a relevant public authority (other than a local government authority). Section 218 (5) of the FM Act states “a public authority that proposes to construct, alter or modify a dam, weir or reservoir on a waterway (or to approve of any such construction, alteration or modification): “(a) must notify the Minister of the proposal, and (b) must, if the Minister so requests, include as part of the works for the dam, weir or reservoir, or for its alteration or modification, a suitable fishway or fish by-pass.” Rivers and Foreshores Improvement Act 1948 repealed by the Water Management Act 2002 The NSW Rivers and Foreshores Improvement Act 1948 (RFI Act) aims to provide effective controls on activities that could harm sensitive waterway and foreshore environments. The Act has provisions that require a permit for excavations, fill and other works within 40m of the top of the bank for rivers, estuaries and lakes as it is recognised that they can have significant detrimental environmental impacts on habitat, water quality, flooding and erosion. Approval under Part 3A of the RFI Act is normally required to: » Excavate or remove material from the bank, shore or bed of any stream, estuary or lake, or land that is not more than 40m from the top of the bank or shore of protected waters; » Build erosion control works or other structures in a river, estuary or lake; or 31/22915/601562 Darling Anabranch Lakes Management Plan » Place any fill material in a river, estuary or lake. The majority of future proposed works in relation to the Anabranch Lakes would likely involve works within 40m of a waterway, however, Clause 22H (1)(b) excludes public authorities (if they were to undertake possible future works) from having to obtain a Part 3A Permit. While various public authorities appear to be exempt from requiring approvals under the RFI Act 1948 for works they plan and are responsible for, DWE (previously the responsibility of DNR) may direct them to undertake remedial works if their activities have or are likely to cause damage to a watercourse. Native Vegetation Act 2003 The Native Vegetation Act 2003 applies to the clearing of native vegetation outside certain specified areas, and requires development consent from the Minister for Planning for certain activities. Section 6 of the Act defines native vegetation as any of the following types of indigenous vegetation: (a) trees (including any sapling or shrub, or any scrub), (b) understorey plants, (c) groundcover (being any type of herbaceous vegetation), (d) plants occurring in a wetland. Section 7 defines clearing native vegetation as being any one or more of the following: (a) cutting down, felling, thinning, logging or removing native vegetation, (b) killing, destroying, poisoning, ringbarking, uprooting or burning native vegetation. Section 25 of the Act goes on to state legislative exclusions. Some exclusions include clearing that is carried out in accordance with a certain license or permit issued under other Acts (i.e. specific permits under the Fisheries Management Act 1994, Water Act 1912, Water Management Act 2000). It should be noted that lakebed native vegetation that was cleared under licence prior to 1983 and has since re-grown (i.e. has not been subsequently re-cleared for cropping purposes) would now be termed protected re-growth and can not be cleared without a new permit under the Native Vegetation Act 2003. Native vegetation may need to be removed depending upon the nature of any proposed future works planned in relation to the Anabranch Lakes (e.g. levee construction, block-banks, regulators) in which case it should initially be determined whether the works will be conducted under another Act as detailed above (this would need to occur in relation to works such as regulators, as under the Native Vegetation Act 2003, clearing within the riparian zone is not generally permitted). For proposal such as future cropping, the LMD CMA in the region should be contacted to determine whether the proposal is likely to proceed (PVP developer) and whether there is a need for a Property Vegetation Plan (PVP). Heritage Act 1977 The Heritage Act 1977 is concerned with all aspects of conservation ranging from the most basic protection against indiscriminate damage and demolition of buildings and sites, through to restoration and enhancement. Heritage places and items of particular importance to the people of NSW are listed on the State Heritage Register. The key to listing on the State Heritage Register is the level of significance. Only those heritage items that are of state significance are listed on the Register. 31/22915/601562 Darling Anabranch Lakes Management Plan In addition, the Heritage Act contains provisions relating to relics. The term "relic" under the Heritage Act "means any deposit, object or material evidence: (a) which relates to the settlement of the area that comprises New South Wales, not being Aboriginal settlement, and (b) which is 50 or more years old." Section 139 of the Heritage Act prohibits a person from disturbing or excavating any land on which the person has discovered or exposed a relic, except in accordance with an excavation permit or a notification granting exception for the permit. As well, a person must not disturb or excavate any land knowing or having reasonable cause to suspect that the disturbance or excavation will or is likely to result in a relic being discovered, exposed, moved, damaged or destroyed unless the disturbance or excavation is carried out in accordance with an excavation permit or a notification granting an exception. Proposed future works in relation to the Anabranch Lakes will need to consider the presence of relics in the vicinity of a development “footprint”. The employment of an archaeologist to conduct an assessment of this type may be required. Threatened Species Conservation Act 1995 The objectives of the Threatened Species Conservation Act 1995 (TSC Act) include: » To conserve biological diversity and promote ecologically sustainable development; » To prevent the extinction and promote the recovery of threatened species, populations and ecological communities; » To protect the critical habitat of those threatened species, populations and ecological communities that are endangered; » To eliminate or manage certain processes that threaten the survival or evolutionary development of threatened species, populations and ecological communities; » To ensure that the impact of any action affecting threatened species, populations and ecological communities is properly assessed; and » To encourage the conservation of threatened species, populations and ecological communities by the adoption of measures involving cooperative management. The TSC Act provides for identification, and classification, of the State listed species, populations and ecological communities with which this Act is concerned. It also provides for the identification of key threatening processes that are most likely to jeopardise the survival of those species, populations and ecological communities. The TSC Act applies to the removal of threatened species, populations and ecological communities on both private and public land. Therefore, it may be applicable to any future proposed works in relation to the Anabranch Lakes. If threatened species, populations or ecological communities are proposed to be impacted, consultation with the relevant state authorities (e.g. DECC) must be undertaken to determine what measures should be implemented to avoid and/or minimise impacts. An offence relating to the damaging of critical habitat is contained in the National Parks and Wildlife Act 1974. That Act also makes it an offence for a person to damage the habitat of a threatened species, population or ecological community. The TSC Act also contains provisions about species impact statements. These statements are employed to measure the significance of the effect of actions on threatened species, populations or ecological 31/22915/601562 Darling Anabranch Lakes Management Plan communities, or their habitats. A species impact statement must be lodged with an application for a licence under this Part if the Director-General determines that the action proposed is likely to significantly affect threatened species, populations or ecological communities, or their habitats. Other conditions pertaining to the granting of a licence under this Act are outlined in Part 6 of the Act: http://www.legislation.nsw.gov.au/viewtop/inforce/act+101+1995+FIRST+0+N Key Threatening Processes A number of listed threatening processes are likely to be already operating in conjunction with the Anabranch Lakes. The following listed threatening processes are identified5 as potentially relevant to future proposed works in relation to the Anabranch Lakes from the perspective of terrestrial fauna (there may be other threatening processes depending upon specific projects). Proposals will need to ensure that new threatening processes do not result, or that existing threatening processes are not exacerbated: » Alteration to the natural flow regimes of rivers, streams, floodplains and wetlands; » Clearing of native vegetation; » Competition and grazing by the feral European Rabbit; » Competition and habitat degradation by feral goats; » Competition by feral honeybees; » Feral pigs; » Infection of frogs by amphibian-chytrid causing the disease chytridiomycosis; » Predation by feral cats; » Predation by the European Red Fox6; » Predation by the Plague Minnow (Gambusia holbrooki)7; and » Removal of dead wood and dead trees. National Parks and Wildlife Act 1974 The National Parks and Wildlife Act 1974 (NPW Act) provides the basis for legal protection and management of Aboriginal sites and objects in NSW. The implementation of the Aboriginal heritage provisions in the Act is the responsibility of the National Parks and Wildlife Service (NPWS). Section 87 of the NPW Act states that a permit may be issued to disturb or excavate archaeological sites or objects. Under Section 90 of the NPW Act, it is an offence to knowingly destroy, deface or damage an object, except in accordance with an approval granted under that section. A cultural heritage assessment is recommended prior to the commencement of any proposed works (e.g. levees, regulators, block-banks) to ensure that items of cultural heritage significance are not disturbed or damaged. 5 Accessed from the DECC internet site on 11 June 2008 http://www.nationalparks.nsw.gov.au/npws.nsf/Content/Key+threatening+processes+by+doctype 6 A final threat abatement plan has been prepared for this threatening process, accessed 23 August 2006 http://www.nationalparks.nsw.gov.au/npws.nsf/Content/Predation+by+the+red+fox+-+final+threat+abatement+plan 7 A final threat abatement plan has been prepared for this threatening process, accessed 23 August 2006 http://www.nationalparks.nsw.gov.au/npws.nsf/Content/threat_abatement_plan_plague_minnow 31/22915/601562 Darling Anabranch Lakes Management Plan Western Lands Act 1901 Cropping permits are issued under Section 18DA of the Western Lands Act, 1901. Permits pertaining to the lakebeds of the Darling Anabranch are classified as cultivation after receding floodwaters and granted by the Western Lands Commissioner. Compliance relating to cropping on lakebeds is under the jurisdiction of the Western Lands Commissioner. If a suspected breach of conditions is observed or reported, the lease may be inspected by a Rangelands Management Officer. Following his/her report, the Western Lands Commissioner may take any compliance action under the provisions of the Western Lands Act, 1901. A lease may also be forfeited under Section 18DA. (12) of the Western Lands Act, 1901, if land is cultivated without a Cultivation Consent or contrary to any condition in a Cultivation Consent. The draft cropping permit conditions are detailed in Appendix C. These conditions are currently under review and have been referred to DECC, DPI and LMD CMA for comment. By-laws The Water Management (WM) Act 2000 will give the Darling Anabranch Private Irrigation District (PID) responsibility of operations in regard to water supply within their boundaries. Lakebed structures would be works that qualify as "water supply works" as described in the WM Act, and consequently can be works of the PID. There are no operational rules in the WM Act describing how a PID should operate its structures. Internal operations are left to the PID. The use of PID works as control structures for containment of environmental flows (E-flows) is outside usual PID operations. The operation of structures for containment of E-flows will depend not on the legislation, but rather on a written agreement between the PID and whoever the controlling body is to achieve the E-flow outcomes. Section 196 of the WM Act provides for the making of by-laws: "a by-law may create an offence punishable by a penalty not exceeding 0.5 penalty units". Penalty units are given a monetary value in the regulations. 31/22915/601562 Darling Anabranch Lakes Management Plan GHD 57 Orange Avenue Mildura, Victoria 3500 T: (03) 5018 5200 F: (03) 5018 5201 E: [email protected] © GHD 2008 This document is and shall remain the property of GHD.
