The Carnarvon water management area is 44 km2 and is located 910 kms north of Perth at the mouth of the Gascoyne River. The boundary for the Carnarvon WMA covers the proclaimed Carnarvon Groundwater Area. However, to ensure that all of the groundwater resources of the Carnarvon area are accounted for, the Carnarvon Water Reserve has been included in the water balance.
The Department of Water is the agency responsible for managing all of Western Australia's water resources, assessing licence applications for water abstraction from private users, local governments and water service providers. The groundwater resources for Carnarvon have been subdivided into basin A (private supply), and Basins B-L (public supply). There are essentially no surface water diversions within the Carnarvon water management area (Water and Rivers Commission, 1999; Water and Rivers Commission, 2004).
Basin A is licensed by the Department of Water and provides water for irrigation to the plantations along the Gascoyne River from privately constructed wells. Basin B-L supplies town water, as well as irrigation supplies from a wellfield managed by Water Corporation in accordance with a license issued by the Department of Water. The Gascoyne Water Cooperative is under contract with the Water Corporation to manage the irrigation scheme (Water and Rivers Commission, 2004).
