A minor flood warning is in place for the Hunter River which remains the only river in the region not to have peaked after the weekend's heavy rain.
The Wollombi Brook, Williams and Patterson rivers are now falling while the Hunter River is still rising at Maitland, and is expected to peak shortly at a little over eight metres.
More than 200 millimetres of rain fell across some parts of the Hunter over the weekend.
The State Emergency Service's Robyn Barko says road closures are still affecting residents.
"The water sitting around Hinton is creating a few issues with road closures at Wollalong heading north out of Hinton and also along the road east out of Hinton there's also a few closures further up stream at Woodville," she said.
"Patterson Road was opened earlier so that's good the people of Patterson aren't isolated so it's just about waiting for the water to move through the river system now."
Robyn Barko says at least a dozen people had to be rescued from flood waters in the Upper Hunter over the weekend.
"We had quite a few flood rescues we had to do. Mainly people driving into flood waters and being stranded so several of our units were quite busy and a few properties that just needed help with their livestock."
