The State Emergency Service is pleading with people not to walk or drive through floodwaters.
It's made the call after two men tried to cross a flooded creek on a quad bike north of Glen Innes on Sunday.
The passenger fell from the bike.
He was able to cling to a tree in the middle of the flooded river for several hours before help arrived.
Deputy Region Controller with the North West SES, Steve Basham, says the situation ended well, but could have had a tragic outcome.
"It appears someone was trying to cross a flooded causeway, and got washed away," he said.
"We were able to rescue that gentleman and we have our fingers crossed there will be no more."
