The three flood gates at High Stanners in Morpeth have now been re-opened.
They were closed at approximately 3am by the Environment Agency following heavy rain yesterday evening. Pumps were used to remove surface water from the area.
But the River Wansbeck level went down this morning, so a team opened them between 11am and 11.30am.
Although Morpeth is still experiencing wet weather, the rain is forecast to ease off this evening and the agency does not expect to have to close the gates again.
Phil Welton, flood and coastal risk manager for the North East, said that a team from the Cramlington depot was deployed by the incident room in Newcastle to close the gates.
He added: “We needed to close them because the water from the river had come up the bank and onto the defences in High Stanners.
“We’re expecting the river level to rise again this afternoon and into this evening, but we don’t think it will reach the same height as last night.
“However, we will be constantly monitoring the situation and will take action if required.”
There are reports of outbuildings flooding at East Mill and staff have gone to speak to residents in that area.
Other staff have been working to clear trash screens.
