During the time of Moctezuma, a dam was built which, along with 18 others, was one of the most outstanding hydraulic works in the area. This work was carried out to prevent the water from Lake Xaltocan from invading Lake Texcoco and flooding Tenochtitlán. Later, during the colonial period, the embankment was reinforced due to constant flooding. In 1604, three chapels were built for the floodgates.
