Acknowledgements This report was prepared by the Water Resources and Eco-Hydrology teams of the Murray– Darling Basin Authority based on modelling conducted by MDBA. The modelling used MDBA models for the River Murray together with models provided by the Victorian Department of Sustainability and Environment, the New South Wales Office of Water, the Queensland Department of Environment and Resource Management, CSIRO and Snowy Hydro Limited. The modelling was undertaken in the Integrated River System Modelling Framework initially developed by CSIRO in the Murray–Darling Basin Sustainable Yields Project and further developed by CSIRO for MDBA for the Basin Plan modelling. Page 3 Preliminary Overview of Constraints to Environmental Water Delivery in the Murray–Darling Basin Executive Summary Background In late 2012 the Federal Water Minister adopted the Basin Plan, providing the first integrated framework for water planning in the Murray–Darling Basin. The Basin Plan aims to restore healthy river systems for the benefit of the environment, communities and agriculture. A central component of the Basin Plan is the establishment of new limits on the volumes of water extracted for consumptive use, known as Sustainable Diversion Limits (SDLs). On a long term average basis, the Basin Plan mandates a Basin-wide SDL of 10,783 GL/y, requiring the recovery of 2,750 GL/y of water for the environment. The Plan also provides for the adjustment of the sustainable diversion limits through supply or efficiency measures that would enable the Sustainable Diversion Limits to be adjusted up, or down, respectively. These SDL Adjustments will be finally determined in 2016. Schedule 5 of the Basin Plan describes the enhanced environmental outcomes to be pursued through the provision of efficiency measures. The Basin Plan also includes a requirement for the Murray–Darling Basin Authority (MDBA) to develop a Constraints Management Strategy by November 2013. The CMS will provide recommendations to governments on priority constraints to be overcome with implementation of recommendations expected to commence in 2014. The Commonwealth government has notionally allocated $200 million to address priority constraints to environmental water delivery in the Basin. What are Constraints? Flow constraints limit how water can be actively delivered through the river system to deliver environmental water requirements. Flow constraints include: Physical constraints, such as the rate at which water can be released from a storage (release capacities) or the level to which water can rise before passing over the river bank onto adjacent land (channel capacities). Operational constraints, relating to the effective management of water resources through a range of operating protocols (for instance, the requirement to maximise reliability of supply for consumptive use, or to protect infrastructure and private property from inundation). Management or Policy constraints, such as the lack of protection for environmental flows as they travel downstream. Why do we need to consider constraints? The regulation of our river systems has resulted in fewer overbank flow events, resulting in a partial disconnect between our rivers and their flood dependent wetlands and floodplains. These ecosystems are under stress because the regulation of the river system predominately Page 4 Preliminary Overview of Constraints to Environmental Water Delivery in the Murray–Darling Basin constrains flows to remain within the main channel. In the last 30 years, there has been a measurable decline in the number and health of native fish and waterbird populations, and an overall decline in the size and health of wetlands, floodplain forests and woodlands. As part of the development of the Basin Plan, MDBA (2012y,z) examined the potential environmental benefits of relaxing key flow constraints in the Murray–Darling Basin. It was found that the combination of addressing constraints and recovering an additional (450 GL/y) of water for the environment could increase: the area of floodplains and wetlands inundated during a mid-to-high flow event; the duration for which these areas are inundated, and; the frequency at which these inundation events occur. An example of these changes is given in Figure 1, showing the River Murray flow at Euston Weir. Modelling conducted by MDBA (2012z) shows that, under water-sharing arrangements prior to the Basin Plan, this flow would have peaked at 65,000 ML/d (red line). Environmental watering under a Basin Plan could increase the flow to 72,000 ML/d (green), and the relaxation of key constraints (with an additional 450 GL/y of environmental water) could further increase this peak flow to 82,000 ML/d. A higher flow will inundate a greater area of water-dependent vegetation and produce improved environmental benefits — Basin Plan watering during this event could increase the inundated area in the river reach by 29% (from 10,500 to 13,500 ha); if key constraints were also addressed this value would increase to 76% (from 10,500 to 18,500 ha). Similar improvements were found along all parts of the southern Murray–Darling Basin. Figure 1 Modelled environmental flow event at Euston Weir under pre-Basin Plan water sharing arrangements (red), post-Basin Plan arrangements with 2,750 GL/y of environmental water (green), and combining an additional 450 GL/y of environmental relaxation of key constraints (blue) Figure 1: Modelled environmental flow event at Euston Weir under pre-Basin Plan water sharing arrangements (red), post-Basin Plan arrangements with 2,750 GL/y of environmental water (green), and combining an additional 450 GL/y of environmental water with the relaxation of key constraints (blue) Page 5 Preliminary Overview of Constraints to Environmental Water Delivery in the Murray–Darling Basin This example illustrates the benefits to the areal extent of floodplain watering which could be achieved if key flow constraints in the Basin rivers were addressed. Addressing constraints also allows managers to have a greater capacity to control the length of time areas (habitats) can be actively watered which is important for many environmental processes. Finally, the capacity to manage the system more actively, and not have to rely solely on unregulated flows, provides greater capacity to actively manage flow events so that watering of important wetlands and floodplains occurs at a frequency that is necessary to ensure resilience. How will this technical report inform the Constraints Management Strategy? The MDBA is developing a Constraints Management Strategy consistent with Chapter 7.08 of the Basin Plan by November 2013. The Constraints Management Strategy must: identify physical, operational and management constraints that affect environmental water delivery; evaluate options, opportunities and risks to water

CD-ROM of this document plus images obtained to date - 1 - - 2 - 1.0 INTRODUCTION The Fish River Water Supply Scheme [FRWS] is a medium size but important water supply with the headwaters in the Central Highlands of NSW, west of the Great Dividing Range and to the south of Oberon. It supplies water in an area from Oberon, north to Portland, Mount Piper Power Station and beyond, and east, across the Great Dividing Range, to Wallerawang town, Wallerawang Power Station, Lithgow and the Upper Blue Mountains. It is the source of water for many small to medium communities, including Rydal, Lidsdale, Cullen Bullen, Glen Davis and Marrangaroo, as well as many rural properties through which its pipelines pass. It was established by Act of Parliament in 1945 as a Trading Undertaking of the NSW State Government. The FRWS had its origins as a result of the chronic water supply problems of the towns of Lithgow, Wallerawang, Portland and Oberon from as early as 1937, which were exacerbated by the 1940-43 drought.

Alought the percentage may seem small as an average (Approx. 17% per annum) large flows have at times contributed markedly in times when the Lower Murray River had periods of low or no flow. This was especially evident during the Millennium Drought when a large flow was shepherded through to the Lower Lakes and Coorong thereby averting what would have been a natural disaster and the possibility of Adelaide running out of water.

    Menindee Lakes, the Lower Darling River and Darling Anabranch)

    THE LIVING MURRAY Information Paper No. 10 IPTLM0010 Health of the River Murray Menindee Lakes, the Lower Darling River and Darling Anabranch) Contents Environmental assets within the river zone Current condition of environmental assets Reasons why some environmental assets have declined in value What can be done to restore environmental values? Existing environmental flows initiatives The system-wide perspective References Introductory Note Please note: The contents of this publication do not purport to represent the position of the Murray-Darling Basin Commission. The intention of this paper is to inform discussion for the improvement of the management of the Basin’s natural resources. 2 Environmental assets within the river zone The lower Darling River system is located at the downstream end of the River Murray system in NSW and is marked by Wentworth to the south and Menindee to the north. It encompasses the Menindee Lakes system, the Darling River below Menindee and the Great Anabranch of the Darling River (referred to hereafter as the Darling Anabranch) and associated lakes. These are iconic riverine and lake systems within the Murray-Darling Basin. In addition, a vital tributary and operating system feeds the lower River Murray. The climate of the area is semi-arid with an annual average rainfall of 200 mm at Menindee (Auld and Denham 2001) and a high potential annual evaporation of 2,335 mm (Westbrooke et al. 2001). It is hot in summer (5–46oC) and mild to cold in winter (-5–26oC). In particular, the lower Darling River system is characterised by clusters of large floodplain lakes, 103 to 15,900 ha in size, located at Menindee and along the Darling Anabranch.
