The original god of the river is the buwaya (crocodile) and he was worshiped by the native people. When the Spanish friars arrived they corrupted his image as a demon and replaced the crocodile with Catholic Saints (San Nicolas of Tolentino and St. Martha).
A lot of legends exists about the buwaya. One of the most famous is the story about the buwayang bato (stone crocodile).
There was once a rich Chinese merchant who was a non-believer in the Roman Catholic god. He was unmindful of the many precautions and rituals of courtesy the local folks observed regarding the crocodile, for he claimed not to be afraid of crocodiles. One day, while he was plying his wares along this part of the river, a big crocodile suddenly appeared, swimming its way towards the boat of the Chinese. In great panic for his life, the Chinese hastly mumbled the name of San Nicolas, imploring the saint to rescue him from the approaching danger. The saint manifested a miracle for this Chinese unbeliever, for the crocodile was frozen and turned into stone. Out of gratitude, the Chinese merchant had a church dedicated to his savior, San Nicolas de Tolentino, along the river, near the site of his rescue.
