Macquarie River Flood Watch
Updated Monday 19th March 2012
Recent rainfall across the catchment has led to increased inflows in the Macquarie River and its tributaries.
On Sunday 4th March 2012 a supplementary event for the Macquarie River downstream of Wellington was announced. As of the 9th March, this event has been extended for the likely duration of the flood mitigation releases from Burrendong Dam. Click here for details relating to pumping times and duration.
Burrendong Dam exceeded 100% on Saturday 3rd March 2012 and entered the Flood Mitigation Zone.at the end of the month.
Note – the withdrawal of carryover and reset to 100% will not occur until the end of March, so those who have the capacity to do so, can still use any remaining carryover so long as it is pumped by the end of this month. At the end of March, all general security and high security accounts will be reset to 100% regardless of how much water has been used up until then.
As of 19th March - the Flood Mitigation Zone Reference Panel met again on Friday 16th March to review the release strategy from Burrendong Dam. In an attempt to ease pressure downstream of Warren, where there are a number of inundation and access issues, it was decided to reduce the release target from 18,000 ML per day at Gin Gin down to 17,000 ML. Flows down the Gunningbar Creek will also be increased to 1,500 ML per day. Under the revised strategy is is expected that the storage level at Burrendong Dam will return to around 110% by the 28th March. The Reference Panel will meet again on the 27th March unless adverse weather is forecast ahead of this date.
The SES has released the expected river heights at Wellington, Dubbo, Narromine and Warren associated with the current release strategy. Click here to view this information.
