Regions used to summarise area of water-dependent native vegetation in the Basin-wide environmental watering strategy (MDBA 2014) for the Murray-Darling Basin.

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.

For the purposes of groundwater resource management, the state of Western Australia is divided into groundwater areas proclaimed under the Rights in Water and Irrigation Act 1914. These groundwater areas are further subdivided into groundwater subareas. The subareas are not proclaimed, but are administrative boundaries used to manage the abstraction and licensing of groundwater resources.

## **Abstract** This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied. This dataset shows the 12 water sources as outlined in the Water Sharing Plan (2006): Upper Namoi Zone 1: Borambil Creek Groundwater Source (hereafter Zone 1). Upper Namoi Zone 2: Cox's Creek (Mullaley to Boggabri) Groundwater Source (hereafter Zone 2). Upper Namoi Zone 3: Mooki Valley (Breeza to Gunnedah) Groundwater Source (hereafter Zone 3). Upper Namoi Zone 4: Namoi Valley (Keepit Dam to Gin's Leap) Groundwater Source (hereafter Zone 4). Upper Namoi Zone 5: Namoi Valley (Gin's Leap to Narrabri) Groundwater Source (hereafter Zone 5). Upper Namoi Zone 6: Tributaries of the Liverpool Range (South to Pine Ridge Road) Groundwater Source (hereafter Zone 6). Upper Namoi Zone 7: Yarraman Creek, (East of Lake Goran to Mooki River) Groundwater Source (hereafter Zone 7). Upper Namoi Zone 8: Mooki Valley (Quirindi-Pine Ridge Road to Breeza) Groundwater Source (hereafter Zone 8). Upper Namoi Zone 9: Cox's Creek (up-stream Mullaley) Groundwater Source (hereafter Zone 9). Upper Namoi Zone 10: Warrah Creek Groundwater Source (hereafter Zone 10). Upper Namoi Zone 11: Maules Creek Groundwater Source (hereafter Zone 11). Upper Namoi Zone 12: Kelvin Valley Groundwater Source (hereafter Zone 12). ## **Purpose** Zones used to describe the status and management of groundwater in the unconsolidated alluvial sediment aquifers associated with the Upper Namoi River and its tributaries. ## **Dataset History** The Namoi and Gwydir Water Management Areas, published in the NSW Government Gazette in November 2001. ## **Dataset Citation** NSW Office of Water (2006) Upper Namoi groundwater management zones.

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.

Groundwater areas proclaimed under the Rights in Water and Irrigation Act, 1914. For the purposes of groundwater resource management, the state of Western Australia is divided into groundwater areas. The extraction and licensing of groundwater resources are managed within groundwater areas. This dataset was formerly known as RIWI Act, Groundwater Areas (DOW-012)
