A photo taken by 9News journalist Kaitlan Steadman at Moruya shows the two waters meeting as the flood crisis continues in the region.
The region has seen substantial rain in the last week, with more forecast in the days to come.
Fire and Rescue NSW have been surveying damage in the area before more rain arrives, and Victorian reinforcements have arrived to help.
At the nearby Mogo Zoo, which was nearly lost to bushfires last year, enclosures are underwater.
A rhino at the wildlife park could be seen wading through deep water with its head and body barely above the water.
