THE Castlereagh River at Mendooran is expected to exceed its minor flood level of 3.3 metres this morning after a three-hour downpour yesterday.
The Macquarie Region of the NSW State Emergency Service (SES) issued a flood warning after an average 40 to 50mm of rain was recorded in the upper Castlereagh valley upstream of Mendooran in the 24-hour period to 6am yesterday.
Most of the rain fell between 3am and 6am.
Incident controller David Monk advised that minor flooding would close the Beni Bridge over the Castlereagh River.
River levels below Mendooran were expected to remain below minor flood level.
“Farmers and landholders are advised to relocate livestock, pumps and machinery to higher ground,” the controller advised in a flood bulletin.
Mr Monk also announced a flood watch for the Talbragar River yesterday because of a robust Coolaburragundy River.
Mr Monk said an average 40 to 50mm of rain fell in the upper Talbragar River catchment in the 24 hours to 6am yesterday, with more rain forecast during daylight hours.
“Locals have reported significant flows in the Coolaburragundy River, which enters the Talbragar River between Leadville and Dunedoo,” Mr Monk said.
“This flood watch means that people living or working along rivers and streams must monitor the latest weather forecasts and warnings and be ready to move to to higher ground should flooding develop.
“Flood warnings will be issued if minor flood levels are expected to be exceeded.”
The Talbragar River at Elong Elong was 1.22 metres and rising at 8am yesterday.
Mr Monk told motorists not to attempt to cross flooded causeways.
