Windamere to Burrendong bulk water transfer

Windamere to Burrendong bulk water transfer

Ongoing dry conditions and record low inflows confirms that the region has entered a new drought of record. Together with below average rainfall, dam levels have lowered across many regions of NSW.

For Burrendong Dam, levels are falling and are forecasted to be about 4% by the end of summer. Under the conditions of the Macquarie-Cudgegong Water Sharing Plan (WSP), a bulk water transfer from Windamere to Burrendong Dam has been scheduled to ensure reliability of supply to all customers in the region.

For Windamere Dam, levels are falling gradually and are forecasted to be about 26% by the end of summer. At the completion of the bulk water transfer, WaterNSW is obligated to ensure that at least 70,000 megalitres of water is left in the dam. This is in accordance with the terms of the Macquarie-Cudgegong WSP and the Bulk Water Transfer (BWT) protocol and will provide a minimum of seven years of water security to local customers.

The bulk water transfer will be over two distinct stages, with the first phase already completed in January 2019 and the second phase to occur late 2019 should the dry conditions continue. During the first phase a total of 35 gigalitres was scheduled to be transferred. Following the two rain events which delivered 26GL of inflows to the Burrendong Dam, the transfer was ceased after just 10GL was taken from Windamere Dam. We will continue to monitor dam levels and inflows to determine the timing and requirements of the second transfer. The graph below shows the planned volumes of water that was due to be released during the first phase.

WaterNSW has revised its forecast flow peaks to 900 megalitres / day in line with community feedback after meeting with customers and other stakeholders in Mudgee.

WaterNSW will monitor water quality during the transfer with a view to possibly increasing  the peak flow to achieve greater environmental outcomes. We are working with customers and stakeholders to potentially to this increase.
