Our Water Resources

Water resources form a critical component of the Northern Agricultural Area (NAR) environment. The surface waters include waterways and wetlands, which provide important habitats for plants and animals, and we rely on the groundwater systems for supply of water to the environment (eg. groundwater fed wetlands), communities and industries in the region.

The NAR is characterised by a diverse system of waterscapes. Saline lakes occur in the eastern reaches of the region where drainage lines consist of broad palaeochannels with mosaics of flat channels and small episodically filled playa lakes. To the west are a variety of groundwater fed wetlands, coastal dune wetlands, swamps, springs, karst limestone cave pools, meandering coastal plain river systems and associated pools and estuaries.

There are current changes in progress for water resource management reform in WA. Securing Western Australia’s water future – a position paper sets out a proposed legislative and policy framework to help deliver new water resource management solutions in Western Australia.

Its primary objectives are to enhance confidence in investment decisions by water users through increased security of access, improved clarity of rules and greater transparency of process; reduce the level of intervention by government in water allocation by enabling the involvement of market-based mechanisms where appropriate; and use appropriate policy and regulation to balance the needs of water users with the protection of water-dependent ecosystems.
