About the project
This project will contribute to better management of environmental water. It will produce a status report on the aquifer system and document the historical development of the groundwater flow model and assess the water balance for the system.
The project will:
- extend two groundwater monitoring bore transects to allow improved monitoring of long-term water level changes caused by increasing groundwater use
- provide a basis for the assessment of impacts of groundwater development through groundwater flow modelling
- provide an improved understanding of the processes of stream/aquifer water exchange
- provide a technical basis for the development of a water-sharing plan for the Upper Lachlan Aquifer that is compliant with the National Water Initiative (NWI)
- communicate the project outcomes to local, state and Australian Government decision makers to enable integrated water resource management.
