Groundwater in the Daly Basin

Tickell, S. 2009, Technical report no. 27/2008D
The Daly Basin is a geological basin that contains two major aquifers in limestone formations. Groundwater cannot move between the aquifers as they are separated by impervious siltstone formations. Significant recharge to the aquifers occurs in most years. The groundwater drains to the Daly River and its major tributaries, causing them to flow all year round. These permanent treams support distinctive ecosystems both within the river and along its banks. The aquifers store and transmit significant volumes of groundwater. Quantities suitable for irrigation can often be extracted from individual bores. There is a small but increasing agricultural industry. Water allocation plans are currently being developed to ensure that both surface waters and groundwaters are used sustainable. Maintenance of dry season river flows and of the ecosystems that they support are the main guiding principles behind water management in the basin.
