2006 Water sharing plan reviews (Lower Lachlan)
Through a Terms of Reference, the Premier of NSW asked the Commission to review the scientific basis of aspects of the Water Sharing Plan for the Lower Lachlan Groundwater Source, prior to its commencement.
In November 2006, the Commission provided a final report to Government.
Overall, the Commission found that information used to inform the average annual recharge estimate and the provision for groundwater dependent ecosystems contains relatively high levels of uncertainty. Improving the knowledge base is critical to improving the quality of the plan and to providing greater certainty for groundwater users.
The Commission developed a series of recommendations that focus on making provisions in the plan for the uncertainty in the available information, as well as improving the information base that informs the plan.
