Valley storage level
Updated: 10 May 2021
Drought response projects
WaterNSW is undertaking a range of drought relief projects, and drought relief project planning, to secure water supplies to affected communities. These projects prioritise water supply to meet critical human needs in the Macquarie Valley.
Nyngan and Cobar Drought Water Security project
WaterNSW with delivery partners EMM Consulting and GHD, will explore viable groundwater sources and pipeline options to extend water supply for critical human needs for Nyngan and Cobar. Investigations will be undertaken in Bogan Shire and Warren Shire to determine groundwater source suitability and yield capacity including options to pipe water to Nyngan, with supply to Cobar through the existing pipeline infrastructure.
Macquarie Valley Drought Relief Strategy
WaterNSW with delivery partner GHD, are working with local councils and DPIE to investigate immediate drought response options and long term asset solutions. These solutions will improve efficient delivery of water for critical human needs downstream and upstream of the Burrendong Dam during low dam water levels. Surface and groundwater options are being investigated along with optimising wastewater reuse, stormwater harvesting and other bulk water saving options.
Draft strategy will be completed in August 2020 and submitted to NSW Government.
Burrendong Deep Water Access
Recent inflows to Burrendong Dam has meant pumping to access the deep storage at the dam will not be required until mid 2021 at the earliest. To date, we have completed the upgrade of the power supply to the dam and constructed the temporary floating pumping stations which will be placed in the reservoir when the dam reaches critical supply levels.
We will continue to monitor the water supply inflows to Burrendong Dam and re-activate the deep storage access project in line with the revised dam depletion forecast to complete the final earthworks.
Bulk Water Transfer from Windamere Dam to Burrendong Dam postponed
With recent minor inflows, the bulk water transfer from Windamere Dam to Burrendong Dam has been postponed in-line with updated modelling.
All works will be in accordance with relevant planning and environmental laws and approvals.
We will continue to work with communities and keep regular updates as we progress, see our contact details below.
