Legend has it that there was a poor old lady visiting the local village. Villagers distrusted her for she seemed dirty and ugly-looking. Fortunately, she was eventually assisted by a good-hearted mother and her son. The truth was that the old lady turned out to be a fairy. She told the mother and son that the village and surrounding areas were about to be struck by a
flood. Despite her warnings, no one believed her, except for the mother and son, who began to build a boat. The next night, a terrible rainstorm began to engulf the village. The mother and son, who had prepared their boat beforehand, survived and saved many people from drowning. The village was subsequently submerged in water and gradually formed into the current Ba Bể Lake. ==References==
