Built in the 18th century to irrigate the surrounding rice fields of Las Piñas & Bacoor. It is a gravity dam on the Zapote River found on the border between Barangay Talon Dos, Las Piñas and Barangay San Nicolas, Bacoor. This is a man-made irrigation dam with its walls made out of adobe (height ranging from 25-30 stacks) and some parts of the flooring made out of cobble stones. Series of buttresses support its perimeter walls and balete trees and bamboo grasses contribute to the enhanced structural integrity of the dam. This dam and its attached water distribution system is an outstanding feat of hydrological engineering. The dam serves as a passageway of commuters from Bacoor and Las Piñas respectively.
