Exploring the critical role we play in groundwater management

We are responsible for managing and allocating groundwater resources across NSW. We do this by using the best available science to inform our policy, and through legislation such as water sharing plans. We also assess and report on the condition of the state’s groundwater resources.

You can view the groundwater data we use to monitor groundwater levels via the Real-time data website. Groundwater flow models also help guide our long-term decision-making for groundwater management.
