The Bega Valley Shire Council has completed work to prevent the Tathra-Bermagui Road flooding.
The Council completed dredging work at the mouth of the Bega River at Mogareeka this week after rain caused the water level to rise.
The shire's Environmental Services Coordinator, Derek Van Bracht, says large swells off the coast are also putting sand back in the river.
Mr Van Bracht says it has been a year since the river was last dredged but he says it is difficult to predict when it will next be required.
‚??It‚??s a bit of a guessing game to a degree but it‚??s monitoring both the catchment conditions and the ocean conditions,‚?? he said.
‚??It all just does depend on the flow coming down the river and obviously our farmers aren't irrigating as much at the moment."
"It does result in more water making its way to the estuary.‚??
