To make the most of the water, the Commonwealth Environmental Water Holder may deliver water to key assets within the Basin over the course of the watering year; carry it over for use in future years; or trade water. In 2013–14 the Commonwealth Environmental Water Holder delivered 982 gigalitres of water to rivers, wetlands and floodplains throughout the Basin, to reconnect wetlands and creeks to Basin rivers. The Commonwealth Environmental Water Holder traded 10 gigalitres of water in the Gwydir and 340 megalitres of water in the Peel. The Commonwealth carried over 450 gigalitres into the 2014–15 water year. By increasing the amount of water available to the environment over time, the Commonwealth Environmental Water Holder has supported the breeding of native plants, fish, birds and other animals in local catchments and throughout the Basin. This water has also improved water quality downstream by flushing salt, sediments and excess nutrients out of the system through the Murray Mouth. Managing the Murray–Darling Basin as a connected system relies on close coordination with state environmental water managers, river operators, the Murray–Darling Basin Authority and other government agencies. The work of the Commonwealth Environmental Water Office is informed by a range of stakeholders including other government agencies, scientists, catchment and local natural resource management agencies, environmental water advisory groups, water user associations, Indigenous communities and local landholders. Together, these stakeholders help the Commonwealth Environmental Water Holder and the Commonwealth Environmental Water Office to plan water use options according to the rules and constraints in the system, seasonal, operational, and management conditions as well as the potential risks of watering within local catchments. Decisions made by the Commonwealth Environmental Water Holder are also made in accordance with the environmental watering plan within the Murray–Darling Basin Plan and have regard for the Murray–Darling Basin Authority’s Basin annual environmental watering priorities. http://www.environment.gov.au/topics/water Summary of the Commonwealth Environmental Water Holder Five years after delivering the first Commonwealth environmental water, it is pleasing to see our work continuing to improve the health and resilience of the Murray–Darling Basin. Since 2009 over 3487 gigalitres of Commonwealth environmental water has been delivered to the Basin’s rivers, wetlands and floodplains. During 2013–14: the total volume of Commonwealth environmental water in Commonwealth accounts was 1449 gigalitres a total of 982 gigalitres of Commonwealth environmental water was delivered 10 gigalitres of water in the Gwydir and 340 megalitres of water in the Peel was traded after evaporative deductions, a total of 450 gigalitres of water was carried over into 2014–15 Commonwealth environmental water contributed to 36 watering actions across a total of 16 catchments in the Basin. Importantly, in 2013–14 water use in the tributaries of the Southern Basin (Goulburn, lower Broken and Campaspe) has contributed to the watering strategy for the Murray, including the Lower Lakes and Coorong. We have also been working with the South Australian Government and the Murray–Darling Basin Authority to get better outcomes from flows and water levels in Lake Alexandrina and the Coorong. Our robust monitoring programme—based on best available science focused on key locations where Commonwealth environmental water is used—shows good evidence that Commonwealth environmental water has increased the number of native fish in the Basin, by supporting the reproduction and recruitment of native fish, their habitat and food sources. It has also helped them to compete with carp. Early evidence from monitoring suggests that the watering strategy for the Murray is achieving outcomes at the Lower Lakes and Coorong, including: improved lake levels and water quality supporting Ruppia tuberosa, a plant in the Coorong, which provides important habitat for fish and waterbirds supporting fish movement from the Coorong into the Lower Lakes and Murray River. Monitoring results finalised in 2013–14 demonstrated that in 2012–13 environmental water exported approximately 30 per cent of an average of two million tonnes of salt that must be removed from the Basin each year to maintain water quality and limit land degradation. Without this water, modelling suggests that salt would have been imported from the Southern Ocean into the system through the Murray Mouth. This builds on the results from 2011–12 monitoring, which indicated that Commonwealth environmental water contributed to 18 per cent of the required export of salt for the year. Monitoring results also demonstrated Commonwealth environmental water lowered the impacts of severe blackwater events. For example, heavy rainfall during March and April 2012 led to significant blackwater concerns in the Murrumbidgee River. This had the potential to severely impact on fish and other aquatic species, where the Murrumbidgee flows into the Murray River. Monitoring has shown that Commonwealth environmental water provided freshwater refuges for fish and helped to dilute blackwater in the Murray. Although the blackwater was a natural event, the environment’s capacity to deal with it had been diminished by river regulation in the Murray. Commonwealth environmental water was used to fill this gap. Effective liaison between waterway, storage and land managers, landholders, the states and the Commonwealth is the cornerstone of Basin reform. It has proven critical to ensuring Commonwealth environmental water planning, delivery and monitoring is delivering outcomes for the Basin. Every drop of Commonwealth water is managed in collaboration and consultation with a range of people who share an interest in the health and resilience of the Basin. I am acutely aware that the decisions I make about the use of the Commonwealth’s water holdings affect people living and working in towns throughout the Murray–Darling Basin. I talk to as many people as possible and listen to their perspectives, and legitimate concerns, with regard to strategies to keep the Murray–Darling Basin healthy. Together, we have marked a number of achievements and highlights this year, including: Providing water to eight of the 10 Basin annual environmental watering priorities identified by the Murray–Darling Basin Authority. Operational constraints and lack of natural cues prevented water from being delivered to support the remaining two priorities. For more on how we met these priorities see table 1 below. The first two trades of Commonwealth environmental water. I sold 10 gigalitres of our Commonwealth environmental water in the Gwydir for $3.217 million and 340 megalitres in the Peel for $32 580. The money is held for reinvestment back into protecting or restoring the environmental assets of the Murray–Darling Basin. My decision to enter the market was preceded by the introduction of the Commonwealth Environmental Water Trading Framework, which provides governance arrangements including operating rules, procedures and protocols. These arrangements provide the necessary reassurance that the Commonwealth will buy and sell water allocations or entitlements in a responsible, fair, equitable, transparent and accountable manner. Commencing recruitment of six local engagement officers in Berri (South Australia); Mildura (Victoria); Deniliquin, Leeton and Dubbo (New South Wales); and Goondiwindi in Queensland as part of our commitment to localism. Finalising long-term monitoring arrangements that will operate from 2014–15 to 2018– 19, resulting in the monitoring of catchments where around 90 per cent of Commonwealth environmental water is held. Developing the interim classification of aquatic ecosystems in the Murray–Darling Basin with the Murray–Darling Basin Authority. The classification can inform a range of environmental water management applications, such as planning, prioritisation, monitoring, evaluation and reporting. It will also assist in analysis for adaptive management purposes. In 2014–15, based on projected storage volumes, it is expected that there will be moderate volumes of environmental water available in the Southern Basin. The volume of water held in public storages in the Northern Basin is currently low, so without further rainfall the amount of environmental water that can be delivered will be limited. Our 2014–15 water options plans take the likely water availability and catchment conditions into account. The plans form a base for us to work with and they are adapted as conditions change. I welcome your feedback and suggestions at any time—please visit our website or email us at ewater@environment.gov.au if you would like to comment. http://www.environment.gov.au/aggregation/commonwealth-environmental-water-office David Papps Commonwealth Environmental Water Holder July 2014 Progress against priorities for 2013–14 2013–14 Portfolio Budget Statements key performance indicators The Commonwealth Environmental Water Office has met its key performance indicators as identified in the 2013–14 Portfolio Budget Statements for the Australian Government Department of the Environment. It has demonstrated: effective use of Commonwealth environmental water for the protection and restoration of environmental assets in accordance with the requirements of the Murray–Darling Basin Plan as detailed in the Commonwealth Environmental Water Outcomes Report 2012–13 (published in March 2013) outcomes from the use of Commonwealth environmental water by publishing monitoring reports online, including reports on the Edward–Wakool River system, the Lower Murrumbidgee River and Murrumbidgee River system and the Lower Murray River engagement with local communities and their stakeholders and consideration of local experience, knowledge and perspectives when undertaking environmental watering by developing annual water use options plans; attending environmental water advisory group meetings and other community meetings in Basin catchments; initiating the recruitment of six local engagement officers to work in Deniliquin, Leeton, Dubbo, Mildura, Berri and Goondiwindi; and improving our online presence through social media. Priorities for 2013–14 The Commonwealth Environmental Water Office 2013–14 Business Plan identified the office priorities for 2013–14, which build on programme deliverables outlined in the 2013–14 Portfolio Budget Statements and priorities outlined in the Department’s Annual Operation Plan for 2013–14. Our progress against these priorities and outcomes is highlighted in the management and administration sections of this report. Additionally, this year the Commonwealth Environmental Water Holder made decisions to make water available to all 10 of the Basin annual environmental water priorities identified by the Murray–Darling Basin Authority. However, due to constraints and/or the lack of natural cues, Commonwealth environmental water could only be delivered to directly support eight of the priority outcomes. See Table 1. Table 1: Meeting environmental water priorities under the Murray–Darling Basin Plan Basin annual environmental watering priorities for 2013–14 Decisions and use of Commonwealth environmental water in 2013–14 Northern Basin Wetlands: Improve the resilience of colonial waterbird populations by supporting breeding events and improving breeding habitat in the Northern Basin wetlands. Supporting breeding events Decision: Contingency volumes of Commonwealth environmental water were set aside in the Gwydir and Lachlan to support colonial bird breeding events. Volume of Commonwealth environmental water delivered: 0 GL due to no breeding events. Supporting waterbird habitat Decision: Up to 94 GL of Commonwealth environmental water was made available for use in the Lower Balonne in 2013–14, subject to trigger flows. On average around 16% of water from Commonwealth holdings in the Lower Balonne (as at end June 2014) will eventually flow into the Narran Lakes following a water harvesting event. Volume of Commonwealth environmental water delivered: 22 GL throughout the Lower Balonne system in a flow event in April 2014. Due to high transmission losses in this event, only a small portion of this would have reached Narran Lakes. See also environmental water use in the Gwydir Wetlands, Macquarie Marshes and Lower Lachlan Wetlands (below), that support waterbird habitat. Gwydir Wetlands: Improve the condition and maintain the extent of wetland vegetation communities in the Gwydir Wetlands (including Ramsar sites) by restoring hydrological connectivity and a flow regime that meets ecological requirements. Decision: Up to 60 GL of Commonwealth environmental water was made available for use in four complementary actions in the Gwydir system, including up to 20 GL in the Gwydir Wetlands. Volume of Commonwealth environmental water delivered: Due to the lack of a natural trigger event, no Commonwealth environmental water was delivered to the Gwydir Wetlands; 32 GL was delivered to the Mallowa Wetlands, Mehi River and Carole Creek (other important Gwydir wetlands). Macquarie Marshes: Improve ecosystem resilience among wetland vegetation communities in the Macquarie Marshes including Ramsar listed sites. Decision: Up to 10 GL of Commonwealth environmental water was made available to maintain the ecological health and resilience of the Macquarie Marshes. Volume of Commonwealth environmental water delivered: 10 GL, in conjunction with additional NSW environmental water. Barwon–Darling River System: Improve habitat and provide opportunities for migration and reproduction of native fish in the Barwon–Darling River system by increasing flow variability and hydrological connectivity. Decision: Up to 24 GL of Commonwealth environmental water was made available to support a more naturally variable flow regime in the Barwon–Darling. Lower Lachlan Wetlands: Improve ecosystem resilience among wetland vegetation communities in the Lower Lachlan wetlands. Decision: Up to 75 GL of Commonwealth environmental water was made available to the Lower Lachlan system in April 2013. Mid-Murrumbidgee Wetlands: Improve the condition of wetland vegetation communities in the Mid-Murrumbidgee Wetlands through a winter or spring fresh. Decision: Up to 150 GL of Commonwealth environmental water was made available for a wetlands reconnection event to protect and maintain the ecological health and resilience of the Mid-Murrumbidgee Wetlands. Volume of Commonwealth environmental water delivered: 13 GL. Volume of Commonwealth environmental water delivered: 74 GL (up to July 2013), in conjunction with additional NSW environmental water. Volume of Commonwealth environmental water delivered: Due to constraints and the lack of an appropriate trigger flow, it was not possible to proceed with the planned use. Environmental water use in the catchment was therefore redirected towards outcomes on the Lowbidgee Floodplain. Lower Goulburn River: Improve habitat and provide opportunities for migration and reproduction of native fish in the lower Goulburn River through reinstating a variable flow regime which includes a large ‘in-channel’ spring/summer fresh. Decision: Up to 215 GL of Commonwealth environmental water was made available for in-stream base flows and freshes within the Goulburn River. Volume of Commonwealth environmental water delivered: 215 GL. The Victorian Environmental Water Holder and The Living Murray also contributed additional water to this event. Mid-Murray River: Improve habitat and provide opportunities for migration and reproduction of native fish in the midMurray River, including the Edward– Wakool and other smaller anabranches, distributary creeks and low-lying wetlands throughout the region. Decision: Up to 45 GL of Commonwealth environmental water was made available to contribute in-stream flows to the Edward– Wakool River System, including ephemeral creeks, to support the condition and reproduction of native fish. Volume of Commonwealth environmental water delivered: 17 GL. Decision: Up to 35 GL of Commonwealth environmental water return flows were made available to contribute in-stream flows to Gunbower Creek to support movement, condition and reproduction of native fish. Volume of Commonwealth environmental water delivered: 19 GL. Lower Murray River System: Improve vegetation condition in wetlands and floodplains and provide cues for native fish recruitment and movement in the Lower Murray River system by enhancing in-stream flow variability. Decision: Up to 47 GL of Commonwealth environmental water was made available in the Great Darling Anabranch within the Lower Darling River System. Volume of Commonwealth environmental water delivered: 47 GL, in conjunction with additional NSW environmental water. Decision: Up to 35 GL was made available for a range of watering actions in the Lower Murray to support wetlands and their vegetation, including to raise water levels at the Locks 8 and 9 weir pools; to support ecosystem recovery at a number of Victorian Mallee and South Australian wetlands; and to support black box woodland vegetation at Hattah Lakes. Volume of Commonwealth environmental water delivered: 35 GL. A number of delivery partners were involved with each of the individual watering events. Decision: Up to 300 GL of Commonwealth environmental water was made available to support a broad range of outcomes within the Murray River channel, low-level floodplain wetlands, Coorong and Lower Lakes. Coorong, Lower Lakes and Murray Mouth: Facilitate Ruppia tuberosa recovery by ensuring appropriate flows into the Coorong; and maintain the connection between the Lower Lakes to improve the water quality in Lake Albert. Over 207 GL of Commonwealth environmental water was made available for supporting vegetation and biota in the Coorong and Lower Lakes. Return flows from northern Victoria were also traded to South Australia to support the Lower Murray. Volume of Commonwealth environmental water delivered: 638.6 GL (which includes 235.1 GL of return flows from upstream watering actions). Water from The Living Murray also contributed to this watering action. Management of Commonwealth environmental water in 2013–14 Commonwealth environmental water made available for use During 2013–14: the total amount of Commonwealth environmental water in Commonwealth accounts was 1449 gigalitres a total of 982 gigalitres of Commonwealth environmental water was delivered a total of 450 gigalitres of Commonwealth environmental water (30 per cent of the total volume available in Commonwealth accounts) was carried over into 2014–15—an increase of 56 gigalitres from the carryover on 1 July 2013. This is equivalent to between 1.1 per cent and 2.2 per cent of public storage capacity across the Basin. Figure 1 shows Commonwealth environmental water holdings. Commonwealth environmental water holdings in the Basin grew from 1632 gigalitres to 2126 gigalitres during 2013–14 (at 30 June 2014; see Appendix A). These holdings will deliver, on average, 1454 giglitres to the environment each year. Figure 2 shows Commonwealth environmental water availability and use since 2008–09. Figure 1: Commonwealth environmental water holdings Figure 2: Commonwealth environmental water availability and use since 2008–09 Catchment summaries Drier conditions continued in the Basin in 2013–14. Commonwealth environmental watering in 2013–14 continued to build on the ecological recovery of riverine and wetland communities following the wetter conditions experienced in Basin catchments from 2010 to early 2012. Watering actions throughout the Basin in 2013–14 were managed and delivered with the assistance of partners including water management authorities, local advisory groups, landholders and scientists. Commonwealth environmental water was usually delivered in conjunction with state government environmental water. During 2013–14 the office, with the assistance of its partners, contributed to the following key environmental watering achievements: coordinated environmental water planning and delivery with other state and local environmental water holders, water managers and infrastructure operators worked with local communities and advisory groups to plan for and manage Commonwealth environmental water generated ecological outcomes in response to Commonwealth environmental watering, which were identified by observations and intervention monitoring. A summary of the volume of Commonwealth environmental water delivered in the Basin during 2013–14 is provided in Appendix B. More detail on each Commonwealth watering event undertaken during 2013–14 is provided in Appendix C. Carryover of Commonwealth environmental water in 2013–14 Carryover is a water management mechanism that entitles water licence holders to defer use of some of their yearly water allocation until the following year, when it may be of more benefit to them. The mechanism is available in regulated parts of the Basin. The Commonwealth carried 450 gigalitres into 2014–15—this volume of carryover was larger than the previous year (see Appendix D). The water is held in nine catchments and is equivalent to about two per cent of the total public storage capacity across the Basin. In 2014– 15, 65 per cent of the carryover will be held in the Southern Basin and 35 per cent of the carryover will be held in the Northern Basin. Carryover is high in the Southern Basin due to the need to have water to facilitate watering actions planned for early 2014–15. Trade of Commonwealth environmental water in 2013–14 Section 106 of the Water Act authorises trade of Commonwealth environmental water. The aim is to improve the capacity of Commonwealth environmental water holdings to meet environmental objectives in the Murray–Darling Basin. This year the Commonwealth Environmental Water Holder developed a trading framework with operating rules, procedures and protocols. The framework is underpinned by both the Water Act and the Murray–Darling Basin Plan trading rules. The framework will ensure that Commonwealth trading activities: support enhanced environmental outcomes have regard to social and economic outcomes consider impacts on the market, including any third-party impacts are undertaken in a manner that meets legislative requirements are financially responsible, fair, equitable, transparent and accountable. The framework also ensures that staff of the Commonwealth Environmental Water Holder and Commonwealth Environmental Water Office act with integrity and high ethical standards. The Commonwealth Environmental Water Holder traded water for the first time in 2013–14. It conducted two allocation sales: one in the Peel Valley and one in the Gwydir catchment of New South Wales. Peel Valley, New South Wales In March 2014 the Commonwealth Environmental Water Holder sold 340 megalitres of regulated water allocation in the Peel Valley through an expression of interest process. The water was not required this year in the Peel River because, after consecutive years of high flows, the priority was for low flows. It is expected that these low flows will be met by releases made to meet consumptive demand. The sale returned $32 580. Proceeds from the sale can be used to meet the costs of managing the portfolio and/or to purchase water for greater environmental benefit within the Murray–Darling Basin. Gwydir, New South Wales The Commonwealth Environmental Water Holder conducted his first tender in January 2014 to sell 10 gigalitres of regulated water allocation in the Gwydir catchment. The Commonwealth Environmental Water Holder made the decision to sell part of the allocation in the Gwydir because: the local floodplains require a drying phase after consecutive wet years the Commonwealth had sufficient water in its accounts to sell some allocation without affecting its ability to meet current and foreseeable future environmental requirements. Because of the strong demand for water from consumptive users, the Commonwealth Environmental Water Holder secured a good return for the water it traded: the sale generated $3.217 million. The proceeds of the sale will be quarantined, as required by section 106 of the Water Act, until the office identifies a purchase of water that will provide greater environmental benefit within the Murray–Darling Basin. Monitoring of Commonwealth environmental watering In 2013–14 five short-term (one-year) monitoring projects took place in the Murrumbidgee, Edward–Wakool, Lower Murray, Goulburn and Gwydir catchments. See Table 2 for more details. The Commonwealth Environmental Water Office monitors its watering actions: to help it to manage Commonwealth environmental water well to demonstrate environmental outcomes to ensure that water is delivered as planned to help manage risks such as unintended inundation. Over the period from 2011–12 to 2019–20 the office is investing around $35 million in monitoring projects in the Basin. From 2014–15 there will be a transition from short (one-year) monitoring projects to longerterm (five-year) monitoring projects. This longer-term intervention monitoring is consistent with our reporting obligations under the Water Act and the Basin Plan. The office is committed to publishing the results of its monitoring. Table 3 gives examples of outcomes by catchment.

Commonwealth environmental water was provided in the Murrumbidgee and Murray rivers to improve water quality by diluting blackwater and providing freshwater refuge for fish. Edward– Wakool In 2011–12 and 2012–13 Commonwealth environmental watering in the Edward–Wakool system contributed to the environmental objectives of the Basin Plan, including: Biodiversity—environmental water contributed to species diversity of native fish populations by supporting their reproduction and food chains. Resilience—environmental water provided refuges for fish during a natural widespread blackwater event in a native fish rich area; refuges contributed to population resilience of native fish. Local outcomes for the Edward–Wakool include: Fish reproduction—environmental watering assisted reproduction of the native carp gudgeon. Refuge—environmental water provided oxygenated refuges for fish and macroinvertebrates during a natural hypoxic blackwater event. Primary production—freshes reset biofilms and supported diversity in primary producers. Murrumbidgee Since 2011 Commonwealth environmental watering in the Murrumbidgee has contributed to the environmental objectives of the Basin Plan, including: Biodiversity—by increasing wetland and riparian vegetation; and providing preferential conditions for native fish, frogs, macroinvertebrates, turtles and waterbirds. Further, native fish species, including bony bream, carp gudgeon, Australian smelt and golden perch, have reproduced and their condition has improved. Ecosystem function—by connecting wetlands to the main river and providing carbon and nutrients from the wetlands to support food chains. In-channel, there has been scouring of algal biofilms, which contribute to food chains and increased fish movement. Flows provided in the Murrumbidgee connect the Basin downstream through to the Coorong and Lower Lakes. Goulburn– Broken system Lower Murray River, South Australia In 2012–13 in the Goulburn River and Broken Creek, Commonwealth environmental water has contributed to the environmental objectives of the Basin Plan, including: Biodiversity—by improving habitat for aquatic fauna and assisting the movement of golden perch through fishways. Ecosystem function—by providing flows that move carbon and nutrients from the river bank into the river to support food chains. Water quality—by providing flows that maintained medium to high levels of dissolved oxygen and promoted the mixing of water (reducing temperature stratification) that supported aquatic fauna during weather conditions that, historically, have resulted in lower water quality. In 2011–12 and 2012–13 in the Lower Murray River in South Australia, Commonwealth environmental water has contributed to the environmental objectives of the Basin Plan, including: Biodiversity—by providing flows that support reproduction, recruitment and improved condition for large-bodied native fish, particularly golden perch. Ecosystem function—by providing flows that connect rivers to fringing wetlands and floodplains, allowing nutrients within the system to be mobilised and transported. Water quality—by providing flows through the Basin and out the Murray Mouth, thereby transporting and exporting salt from the system and improving salinity levels in the Lower Lakes, Coorong and Murray Mouth. Resilience—by supporting the recovery of ecosystems following the drought. Administration of Commonwealth environmental water Directions given to the Commonwealth Environmental Water Holder No directions were given to the Commonwealth Environmental Water Holder in 2013–14 by the Minister, Parliamentary Secretary or Secretary of the Department. Longer-term portfolio planning Multi-year planning, which builds on the Commonwealth Environmental Water Office’s annual planning for environmental water use, helps to support environmental outcomes across the Murray–Darling Basin by making Commonwealth environmental water available for use over multiple years. This longer-term commitment gives certainty to delivery partners and communities and helps the office to meet its obligations under the Basin Plan. The office has already begun to use multi-year planning. The office has worked collaboratively with delivery partners to make Commonwealth environmental water available over three years for a number of lower Murray wetlands in the Victorian Mallee region and over five years for the Warrego River at Toorale National Park and State Conservation Area. The office continues to seek opportunities to develop longer-term arrangements and move toward longer-term planning for all the catchments in which the Commonwealth holds water. To manage Commonwealth environmental water holdings efficiently and effectively, all portfolio management options—including use, water carryover for future years and trading (disposal or acquisition)—must be used. The office is currently developing an approach to longer-term portfolio management planning that will improve its capacity to strategically manage use, carryover and trade to maximise environmental outcomes. Murray–Darling Basin Plan—participation in implementation In 2013–14 the office participated in the following committees to advise on and support implementation of the Basin Plan: the Basin Plan Implementation Committee and two of its working groups—the Environmental Watering Working Group and the Monitoring and Evaluation Working Group the Sustainable Diversion Limits Adjustment Assessment Committee. Management of the portfolio of Commonwealth environmental water The annual Commonwealth Environmental Water Carryover Report for 2013–14 into 2014–15 can be found on the Department’s website. http://www.environment.gov.au/water/cewo/publications/cew-carryover-2013-14-into-2014-15 The Commonwealth Environmental Water Office published statements on the management of Commonwealth environmental water, including trade, on the Department’s website during 2013–14. http://www.environment.gov.au/topics/water/commonwealth-environmental-wateroffice/portfolio-management/portfolio-management Information about Commonwealth environmental water holdings was updated each month on the website. http://www.environment.gov.au/topics/water/commonwealth-environmental-water-office/aboutcommonwealth-environmental-water In 2013–14 the Commonwealth Environmental Water Holder published a trading framework that includes operating rules, procedures and protocols. http://www.environment.gov.au/topics/water/commonwealth-environmental-water-office/trade Risk management for Commonwealth environmental water The Commonwealth Environmental Water Holder is committed to ensuring transparency and accountability in the use of Commonwealth environmental water. The office has a series of frameworks in place to ensure that risk management is at the core of its business. These frameworks include: Framework for Determining Commonwealth Environmental Water Use Commonwealth Environmental Water—Monitoring, Evaluation, Reporting and Improvement Framework Commonwealth Environmental Water Trading Framework Environmental Water Outcomes Framework. The office also has criteria for assessing options for Commonwealth environmental water which all Commonwealth environmental watering actions are assessed against. http://www.environment.gov.au/resource/commonwealth-environmental-water-annual-useoptions-planning-approach The office takes a conservative, risk-based approach to environmental flow management, reflecting our good neighbour policy, so that unintended impacts do not occur. All decisions on water use are informed by a comprehensive risk assessment and local delivery partners put arrangements in place to ensure that any risks that have been identified are appropriately managed. If the office identifies any potentially unacceptable impacts on private property, it negotiates with affected landholders to avoid or minimise any potential problems and then seeks consent to watering events. In many situations landholders support watering events because the outcomes are mutually beneficial—for example, watering events can not only provide environmental benefits but also support the productivity of floodplain pastures. The current operating framework that applies to all types of water deliveries has been designed to avoid undesirable flooding of private land. At present, all river operators deliver Commonwealth environmental water orders within that operating framework. Under the framework, the flow rate at which Commonwealth environmental water is generally ordered and delivered is below the operational limits—this is to mitigate risks such as unpredictable local inflows as a result of rainfall. Environmental water shepherding Water shepherding mechanisms or arrangements allow for protection and re-use of water entitlements (whether regulated or unregulated). They build on existing protections such as the Murray–Darling Basin Cap on diversions (and the future sustainable diversion limits under the Basin Plan) and the conditions of all water licences. Work on the Nimmie–Caira shepherding project, as well as other projects (such as New South Wales Barwon–Darling and Queensland unregulated streams), is expected to continue in 2014–15. Providing information The Department’s website is the office’s primary tool for making information publicly available. It contains: information about environmental water holdings information about management and use of Commonwealth environmental water in each Basin catchment frameworks for making water use decisions and managing water reports on monitoring projects and outcomes reports that the office has drafted or commissioned. Also, through the website members of the public can make comments and suggestions on the potential use of Commonwealth environmental water. http://www.environment.gov.au/aggregation/commonwealth-environmental-water-office During 2013–14 the office produced the following reports on its activities: Commonwealth Environmental Water Office Annual Report 2012–13 (in Department of Sustainability, Environment, Water, Population and Communities Annual Report 2012– 13) Commonwealth Environmental Water Office 2013–14 Business Plan Commonwealth Environmental Water Office 2012–13 Outcomes Report Commonwealth Environmental Water Portfolio Management Statements Commonwealth Environmental Water Carryover from 2012–13 into 2013–14 Report Commonwealth Environmental Annual Water Use Options Planning Documents for 2013–14 and 2014–15 Interim Classification of Aquatic Ecosystems in the Murray–Darling Basin monitoring and evaluation reports on Commonwealth environmental watering commissioned by the office. http://www.environment.gov.au/water/cewo/publications The office also maintains a subscription email database and has an active Twitter presence to communicate with interested parties. Working with and obtaining advice from others In 2013–14 the office continued to focus on a range of stakeholder engagement activities, including: commencing the process of recruiting six Commonwealth Environmental Water Office local engagement officers participating in planning processes, including regularly meeting with local partners and landholders on a catchment-by-catchment basis releasing publications and engaging in targeted consultation on issues including water use, water trade, carryover and monitoring and evaluation. The Commonwealth Environmental Water Scientific Advisory Panel, which advises the office, met once in 2013–14. A review of the panel’s terms of reference is under way and is due to be finalised in 2014–15. The Commonwealth Environmental Water Stakeholder Reference Panel ceased operations as of 10 February 2014. Its last meeting was held on 6 November 2013. The office continues to meet and engage with many stakeholder groups and individuals, including state government bodies, river operators, catchment management authorities, local environmental water advisory groups, not-for-profit water and land management organisations, other environmental water holders, landholders and the Murray–Darling Basin Authority. Indigenous engagement The office aims to increase its engagement with Indigenous people so that mutual environmental and cultural outcomes can be achieved. In 2013–14 the office engaged with groups such as the Northern Basin Aboriginal Nations and the Murray Lower Darling Rivers Indigenous Nations as well as interested Indigenous communities—for example, the Ngarrindjeri, Yorta Yorta and Nari Nari people, and the Barkindji Maraura Elders Environment Team—to identify potential opportunities for Commonwealth environmental water to support mutual environmental and cultural outcomes. The office is also working with the National Native Title Council to support the National Cultural Flows Research Project. Interim classification of aquatic ecosystems in the Murray–Darling Basin In 2013–14 the Commonwealth Environmental Water Office and Murray–Darling Basin Authority jointly developed an interim (point in time) classification and typology of aquatic ecosystems across Australia’s Murray–Darling Basin by adopting the Australian National Aquatic Ecosystems Classification Framework. The classification system, developed by the Commonwealth and state and territory governments, establishes for the first time a consistent and systematic method of classifying aquatic ecosystems across the Australian landscape. Business and information systems The office has established the Environmental Water Management System to improve its efficiency and help it to meet Basin Plan reporting requirements. The system manages Commonwealth environmental water holdings information and provides financial and volumetric tracking of watering actions. The Environmental Assets Database holds information on the management and health of environmental assets in the Basin and the use of Commonwealth environmental water to protect and restore the health of these assets. Environmental Water Holdings Special Account 2013–14 The Environmental Water Holdings Special Account is established under the Water Act to pay costs, expenses and other obligations incurred in managing Commonwealth environmental water holdings. At the start of 2013–14 the special account balance was $43.8 million. Funding of $27.4 million was credited from the Sustainable Rural Water Use and Infrastructure Program to the account at the end of the financial year. During 2013–14, $14 million was spent on annual water entitlement fees and allocation delivery costs (including use fees and pumping), which accounted for approximately 66 per cent of total expenditure for the year. At 30 June 2014 the special account balance was $53.083 million (of which $9.2 million has been committed for environmental watering actions and other projects). The key expenditure in 2013–14 is shown in Table 4. Table 4: Environmental Water Holdings Special Account expenditure Category of expense Fees and charges for entitlement holdings and allocation delivery1 Total costs ($ million) 14.036 Monitoring and evaluation 5.919 Development and maintenance of environmental registers and water accounting systems 1.353 Environmental works and measures 0.080 Hydrological modelling services 0.036 Total 1 21.425 Fees and charges include $9.9 million for annual water entitlement fees and $4 million for allocation use fees paid to state water authorities for the operation, maintenance and replacement of rural water infrastructure; and $0.096 million for allocation pumping costs.
