and the Rehabilitation of Marilao River
as a New Tourist Destination

La Prenza Dam, the main focus of this proposal, has been used as irrigation for the water that flows directly from mountain range of Sierra Madre to support not only for the town of Marilao but also for the adjacent towns of Bocaue and Sta. Maria. It has also served as a recreational and fishing site even to nearby commoners. A lot of stories of love had also happened in this place; but a lot of lives have also been taken away due to the negligence in their part. It is also the 1989 communal irrigation system; serves as a check gate to prevent water overflow from destroying rice crops in the area.

It is also a combination of a gravity-type dam and a spillway. Gravity dams are dams that are constructed to hold back water using only their own weight. To do this, they are constructed using extensive amounts of concrete, making them difficult and expensive to build. A spillway is a section of a dam designed to pass water from the upstream side of a dam to the downstream side. Many spillways have floodgates designed to control the flow through the spillway.

A dam is a barrier that impounds water or underground streams. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. Hydropower and pumped-storage hydroelectricity are often used in conjunction with dams to generate electricity. A dam can also be used to collect water or for storage of water which can be evenly distributed between locations.

Common purposes of Dam Construction
• Power Generation
Hydroelectric power is a major source of electricity in the world. Many countries that have rivers with adequate water flow, that can be dammed for power generation purposes. For example, the Itaipu Dam on the Paraná River in South America generates 14 GW and supplied 93% of the energy consumed by Paraguay and 20% of that consumed by Brazil as of 2005.

• Water supply
Many urban areas of the world are supplied with water abstracted from rivers pent up behind low dams or weirs. Examples include London – with water from the River Thames and Chester with water taken from the River Dee. Other major sources include deep upland reservoirs contained by high dams across deep valleys such as the Claerwen series of dams and reservoirs.

• Stabilize water flow/irrigation
Dams are often used to control and stabilize water flow, often for agricultural purposes and irrigation. Others such as the Berg Strait dam can help to stabilize or restore the water levels of inland lakes and seas, in this case the Aral Sea.

• Flood prevention
Dams such as the Blackwater Dam of Webster, New Hampshire and the Delta Works are created with flood control in mind.

• Land reclamation
Dams (often called dykes or levees in this context) are used to prevent ingress of water to an area that would otherwise be submerged, allowing its reclamation for human use.

• Water diversion
A typically small dam used to divert water for irrigation, power generation, or other uses, with usually no other function. Occasionally, they are used to divert water to another drainage or reservoir to increase flow there and improve water use in that particular area.

• Navigation
Dams create deep reservoirs and can also vary the flow of water downstream. This can in return affect upstream and downstream navigation by altering the river's depth. Deeper water increases or creates freedom of movement for water vessels. Large dams can serve this purpose...
