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 1% by the late January 2020. 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 water supply to meet critical human needs in the region.

For Windamere Dam, levels are falling gradually and are forecasted to be about 26% by the start of February 2020 when the next bulk water transfer is being scheduled to take place. About 25,000 megalitres (or 25 gigalitres (GL)) is planned to be transferred over a three month period from Windamere Dam to Burrendong Dam. At the completion of the bulk water transfer, WaterNSW is obligated to ensure that at least 70 GL of water remains in the dam. This is in accordance with the terms of the Macquarie-Cudgegong WSP and the Bulk Water Transfer (BWT) protocol. Modelling confirms this will provide over five years of water security to Cudgegong water users.

The bulk water transfer has been planned over two distinct phases, with the first phase already completed earlier in January 2019 and the second phase now planned for February 2020 should the dry conditions continue. During the first phase a total of 35 GL was scheduled to be transferred. Following the two rain events which delivered 26 GL of inflows to the Burrendong Dam, the transfer was ceased after just 10 GL was taken from Windamere Dam. We will continue to monitor dam levels and inflows to determine the timing and requirements of the second transfer.
