Many people of Barangay Libtong believe that Libtong got its name from a mysterious lake that lies in the south-eastern side of the barangay. According to a story that had been told to them by their ancestors, there was, once upon a time, a tribe in this place who lived with many beliefs.  One of the beliefs was that during feasts, all villagers should wear clothes with the same color with that of their chieftain, otherwise, something terrible will happen to them.  One day, a wedding was being celebrated in the village of which the bride is the chieftain’s daughter. The couple and the chieftain were in red clothes so with the village people except for one boy who wore another color.  During the celebration, the village people heard a loud and sharp cry of dog.  The people saw the dog crying and digging under the chieftain’s hut.  The villagers were surprised to see that water was coming out from the hole that was dug by the dog.  The water was coming out stronger until the village was flooded.  The people ran for higher grounds but it was too late, the place where the wedding took place instantly became a lake drowning to death all the villagers.  People around the place believed that this was the consequence of the belief that was broken. “Nailibsongda” as they considered it until the place was referred to as “Libsong” and later on pronounced as “Libtong”.

               This famous “lake that never leaks” covers an area of more than a hectare. During the past decades, the water does not lessen during summer neither it overflows during rainy season. At present, effects of nature and human may have been causing loses of its grandeur; of which the municipal local government unit and local residents are trying their best to preserve it beauty for tourism purposes. There was a time during the early Marcos Regime that this lake was named “Imelda Lake” in honor of the former First Lady Imelda R. Marcos purposely to invite the government to share funds for its development, but it vain.
