The State Emergency Service says at least a dozen people had to be rescued from flood waters in the Upper Hunter over the weekend.
A minor flood warning is still in place for the Hunter River and Wollombi Brook 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.
Patterson residents are no longer isolated, after Patterson Road was reopened this morning.
The State Emergency Service's Robyn Barko says it was another busy 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."
Robyn Barko says the situation is improving.
"The Williams Rivers and Patterson Rivers are now falling and the water above Singleton and above Greta have started to fall we are just waiting for that peak to start to drop at Maitland now," she said.
