MOLINO DAM

HISTORY OF MOLINO DAM ➢ Also known as Prinza Dam

➢ From 1780 to 1893, the hacienda administrators built forty-

five irrigation dams with tunnels, waterways, and irrigation canals in order to channel available water sources to excellent use, that way securing rice paddies during extended drought periods.

HISTORY OF MOLINO DAM ➢ Constructed in the 18th century by the Spaniards, during

the Spanish Colonial Era. ➢ It was built in the 18th century to irrigate the surrounding

rice fields in Las Piñas & Bacoor.

MOLINO DAM ➢ One of the pressing problems that have occupied the

administrator's attention was the Prinza Dam. Father Moreno redacted a letter urging the "need and great convenience of repairing the Prinza Dam" especially due to protracted drought periods. ➢ The 1885 drought moved the parish curate to request for the

rehabilitation of the dam wall answer the need for food of many residents. It would be extremely beneficial for San Nicolas, he reasoned out, if the walls of the dam were raised higher. ➢ The proposed repair aimed to provide more water capacity to the

Prinza Dam. On April 24, 1885, Provincial Definitorium approved the budget proposal of 3,926.00 pesos and the dam was reconstructed.

MOLINO DAM ➢ In commemoration of Saint Ezekiel Moreno's

dedication and contribution to the people of Cavite and Las PiĂąas City the local government embarked on a joint project entitled "Rehabilitation and Restoration of Prinza", a beautification and preservation effort to develop their sections of the historic dam into parks. A layer of cobblestones were also added to the upper deck of the dam and safety posts on both sides were added as guide for the pedestrians.

PRESENT CONDITION OF MOLINO DAM  Currently, the Prinza Dam serves as a footbridge for easy

access between Las Piñas City and Bacoor, Cavite.  It is no longer used for irrigation as the surrounding land

around the dam are now residential areas.

PRESENT CONDITION OF MOLINO DAM  Now, the dam is an exciting tourist destination where one

can eat and dine on a bamboo floating restaurant.  Serves as a recreation area and as a tourist attraction.

MOLINO DAM ➢ Impounds: Zapote River ➢ Height: 10 meters

➢ Length: 450 meters ➢ Width: 600 meters

MOLINO DAM ➢ A gravity dam on the Zapote River located on the

border between Barangay San Nicolas I in Bacoor, Cavite and in Las Piñas, Metro Manila, in the Philippines. ➢ Its walls made out of adobe rocks (height ranging from

25-30 stacks) and some parts of the flooring made out of cobblestones.

MOLINO DAM ➢ It is a man made irrigation dam use to irrigate the

land and surrounding rice fields they own and leased out in the present cities of Las Piùas and Bacoor. ➢ This dam effectively raised the level of water in the

upper Zapote River three stories high; the same level as the fields and separated the fresh water coming from Almanza and the Molino River from the salt water of the lower Zapote River.

ADVANTAGES OF MOLINO DAM  During the Spanish period, it helps to irrigate the land

and surrounding rice fields.  The growth of vegetation flourished because of the

natural composition of the building materials.  Separated the fresh water coming from Almanza and

the Molino River from the salt water of the lower Zapote River.

ADVANTAGES OF MOLINO DAM  Easier to travel from Las Piñas to Bacoor Cavite as it

serves as a connecting foot bridge between the two places.  As it now serves as a tourist spot. It is now more

economical to the people residing close to the area.

ISSUE AND CHALLENGES:  Protracted drought periods.  During 2018, visible bubbles starts to form at the

surface water of the dam. According to the DENR, it is possibly the result of the pressure and the quality of the water.

SOLUTIONS: ï‚— Repair and rehabilitation of the dam to increase it

water capacity.
