The Basin Plan's management arrangements will be implemented at a local scale through water resource plans prepared by the Basin states for accreditation by the Commonwealth Water Minister. The Basin has been divided into 19 surface-water water resource plan areas. The boundaries of these areas are shown in the Surface Water Water Resource Plan Areas dataset. The surface-water water resource plan areas cover the entire Basin, including those areas not previously subject to water planning arrangements. The water resources in the Murray-Darling Basin to which the Basin Plan will apply are identified in the Water Act 2007 (Cwlth). These resources do not include the Great Artesian Basin water resources.

The Murray-Darling Basin Plan (available at http://www.comlaw.gov.au/Details/F2012L02240) was developed under the Commonwealth Water Act 2007 and aims to deliver a coordinated approach to water use by States and Territories in the Murray-Darling Basin (MDB), underpinned by a commitment to restoring the long-term health of rivers and wetlands in the Basin. To achieve this, the Basin Plan sets a long term average Sustainable Diversion Limit (SDL) for surface water and groundwater use across the major valleys in the MDB, and incorporates an Environmental Watering Plan (EWP) that ensures surplus water beyond SDLs is made available for the natural floodplain and wetland systems. The EWP is central to the Basin Plan as it aims to achieve the best possible environmental outcomes in its use of environmental water, in terms of size, timing and nature of river flows. The EWP is supported by the Environmental Water Recovery Strategy, a voluntary water buyback instrument (SEWPAC 2012). The long term average SDL for surface water flow is currently set by the Basin Plan at 10,873 gigalitres per year (GL/y). This includes 3,468 GL/y for the northern Basin, which establishes a water ‘saving’ of 390 GL/y from water allocations previously set under the Living Murray initiative (MDBA 2011). These savings are available as ‘environmental water’ which is regulated by the Commonwealth Environmental Water Office (CEWO) via the EWP. Water allocations in the northern Basin are currently under review via the Northern Basin Review, which is due for finalisation in mid-2016. This review is expected to improve environmental science in relation to floodplain systems in the Condamine-Balonne and Barwon-Darling River systems, and may recommend changes to the Basin Plan accordingly. A key part of the Review is to improve knowledge about environmental assets within river systems of the northern Basin (e.g. floodplain and wetland vegetation, fish, water birds), and how they respond and interact to fluctuations in surface water flow. Improved knowledge about the native vegetation of inland floodplain systems is fundamental to the Northern Basin Review. To improve information about the distribution and extent of floodplain and wetland vegetation types in the northern Basin, Eco Logical Australia (ELA) was commissioned by the Murray Darling Basin Authority (MDBA) to map the distribution of plant community types (PCTs) within a large section of the Darling floodplain west of Louth, and within the Condamine-Balonne system south of the NSW-Queensland border. An improved knowledge about the distribution and extent of floodplain PCTs will inform how environmental water allocations might be refined, and is thus an important component of the Northern Basin Review.

This combined map, table and dataset list Traditional Owner groups for the purpose of water resource planning for each of the 19 surface water and 19 groundwater resource plan areas (WRPAs) for the Murray-Darling Basin. The table and map has been compiled using a number of sources and should only be used as a preliminary guide. Endorsed by Murray Lower Darling Rivers Indigenous Nations, August 2018, and Northern Basin Aboriginal Nations, October 2018.

The dataset shows MDB Water Quality Regions / Zones as at March 2010. The dataset has been derived from the SRA Valley Zones as created by Sustainable Rivers Audit (SRA) program in Murray Darling Basin Authority (MDBA) which is a comprehensive assessment of river health taken in the Murray Darling Basin. This dataset was constructed in GDA94 coordinate system, using the Australian Water Resources Council (AWRC) catchment layer and were then subdivided into altitude zones. These altitude zones correspond to one of seven categories: Montane, Upland, Slopes, Lowland, Upper, Middle, Lower and Mt Lofty. The water quality regions have been defined using similar geomorphologic and geophysical landscape characteristics. The amalgamations of altitude zones were determined, using similar water quality parameter values. The water quality regions as defined by this dataset have been used in the guide to the Basin Plan.

A collection of data for irrigation infrastructure across the Murray-Darling Basin, for purposes of natural resource management, salinity and drainage planning. Data themes contributed by many organisations and landowners, collated to a common data standard by the State Contributing Agencies, included drain locations and details, drainage catchment boundaries, drainage structures, supply channels and other related information. This archive version includes the Electronic Atlas version 2.2 as published on CD in 2003 and State deliverable data layers used in the Electronic Atlas version 2.2.
