Legend of the Lakes
It was told that these two lakes were named after two lovers. According to the legend, a beautiful woman named Pandin was cursed not to step on the earth, otherwise, something terrible would befall her. Yambo, her ardent lover, did not know about the curse and had made her step on earth, after which there was a terrible noise followed by the cracking grumble of the earth and a heavy downpour eventually converted the area into twin lakes separated from each other by a bare strip of land.
