The La Mesa Watershed Reservation is a protected area that preserves the only major watershed in Metro Manila, Philippines. Also known as the Novaliches Watershed, it contains the last remaining rainforest of its size in Metro Manila surrounding the La Mesa Dam and Reservoir, the primary source of potable drinking water for 12 million residents in the Manila metropolitan area. [1] The area is under jointly controlled and supervised by the Department of Environment and Natural Resources and the Metropolitan Waterworks and Sewerage System. It was established in 2007 through Proclamation No. 1336 issued by President Gloria Macapagal Arroyo. [2]
The La Mesa Watershed encompasses an area of 2,659 hectares (6,570 acres) in the northern fringes of Quezon City, Caloocan and Rodriguez, Rizal. It is situated on a flat-topped hill or mesa at the foot of the southern Sierra Madre mountain range west of the Marikina Valley. It is about 9 kilometres (5.6 mi) north from the center of Quezon City in Diliman, and some 20 kilometres (12 mi) northeast from the center of Manila in Rizal Park.
The highest elevation in Quezon City is in the watershed's northern tip at 250 metres (820 ft) above sea level. [3] It centers on the 700-hectare (1,700-acre) La Mesa Dam and Reservoir in Novaliches, an artificial lake which was created in 1929 as part of Manila's Ipo–Novaliches–San Juan water system under the American colonial government. [4] The surrounding 2,000-hectare (4,900-acre) forest contains more than 50 kilometres (31 mi) of nature trails and serves as the lungs of Metro Manila, providing it with clean air. [5] It also contains the 33-hectare (82-acre) ecological park known as the La Mesa Eco Park. This park located at the southern edges of the watershed in East Fairview is administered by the Quezon City Parks Development and Administration Department and was opened in 2003. [6]
The Tullahan River which passes through Malabon and Navotas starts from the La Mesa Watershed Reservation. It flows until Manila Bay. [7]
In 2015, it was reported that 300 thousand people visit the La Mesa Watershed Reservation annually according to park officials. The protected area also has 50 kilometers (31 mi) of nature trails. [8]
The La Mesa Watershed comprises a variety of ecosystems that is home to many indigenous and endemic species of flora and fauna. Approximately 1,800 hectares (4,400 acres) are under forest cover and 300 hectares (740 acres) are open areas, pastures and areas under cultivation. Several portions of the La Mesa reservoir are shallow with exposed mudflats, swampforest, reed and other swamp vegetation. Its forest serves as an important breeding area for a variety of wildlife species and birds such as the little heron, black-crowned night heron, osprey, Japanese sparrowhawk, plain bush-hen, common moorhen, Eurasian coot, Philippine coucal, Philippine nightjar, island swiftlet, spotted wood kingfisher, common kingfisher, white-collared kingfisher, Philippine pygmy woodpecker, barn swallow, pied triller, ashy minivet, Philippine bulbul, black-naped oriole, Oriental magpie robin, Arctic warbler, grey-streaked flycatcher, pied fantail, yellow-bellied whistler, grey wagtail, brown shrike, olive-backed sunbird, and lowland white-eye. [9]
The most common tree species found in the reservation are Malay beechwood, earleaf acacia, acacia mangium, narra, mahogany, teak, ipil-ipil, alibangbang and bangkal. [10]

Threats to the watershed's biodiversity come from land conversion and deforestation from illegal harvesting of forest products. [11] In 2014, the La Mesa park ranger recorded a total of 25 informal settler families living within the reservation who engage in slash-and-burn cultivation or kaingin. A portion of the watershed was also reportedly sold as housing for employees of the Metropolitan Waterworks and Sewerage System which was flagged by the Commission on Audit. Former Environment Secretary Gina Lopez cancelled the environmental compliance certificate for the sale in December 2016. [11]
The Manila Seedling Bank conducted a five-year reforestation program at the watershed from 1978 to 1983. [12] In a 2013 vulnerability assessment by scientist Cristino Tiburan, the La Mesa Watershed Reservation was found to be prone to erosion and landslide. [11]
Metropolitan Manila, commonly shortened to Metro Manila and formally the National Capital Region, is the capital region and largest metropolitan area of the Philippines. Located on the eastern shore of Manila Bay, the region lies between the Central Luzon and Calabarzon regions. Encompassing an area of 619.57 km2 (239.22 sq mi) and with a population of 13,484,462 as of 2020, it is composed of sixteen highly urbanized cities: the capital city, Manila, Caloocan, Las Piñas, Makati, Malabon, Mandaluyong, Marikina, Muntinlupa, Navotas, Parañaque, Pasay, Pasig, Quezon City, San Juan, Taguig, and Valenzuela, along with one independent municipality, Pateros. As the second most populous and the most densely populated region in the Philippines, it ranks as the 9th most populous metropolitan area in Asia and the 6th most populous urban area in the world.
Quezon City, also known as the City of Quezon and Q.C., is the most populous city in the Philippines. According to the 2020 census, it has a population of 2,960,048 people. It was founded on October 12, 1939, and was named after Manuel L. Quezon, the second president of the Philippines.

This is an overview of current and former national capital cities in the Philippines, spanning from the Spanish colonial period to the current Fifth Philippine Republic. The current capital city, Manila, has been the country's capital throughout most of its history and regained the title through a presidential order in 1976, with Metro Manila serving as the National Capital Region (NCR) since 1978.
The La Mesa Dam and Reservoir is an earth dam in Quezon City, Philippines. Its reservoir can hold up to 50.5 million cubic meters, occupying an area of 27 square kilometers (10 sq mi). It is part of the Angat-Ipo-La Mesa water system, which supplies most of the water in Metro Manila.
Angat Dam is a concrete water reservoir embankment hydroelectric dam that supplies Metro Manila and nearby provinces with water. It was a part of the Angat-Ipo-La Mesa water system. The reservoir supplies about 90 percent of raw water requirements for Metro Manila through the facilities of the Metropolitan Waterworks and Sewerage System and it irrigates about 28,000 hectares of farmland in the provinces of Bulacan and Pampanga.
The Metropolitan Waterworks and Sewerage System, formerly known as the National Waterworks and Sewerage System Authority (NAWASA), is the government agency that is in charge of water privatization in Metro Manila and nearby provinces of Cavite and Rizal in the Philippines. It split the water concession into an east and a west concession with Manila Water being awarded one contract and Maynilad Water Services being awarded the other.
Several bulk water supply projects on the upper portion of the Kaliwa River Watershed have been proposed by the Philippine Government since the 1970s, with the intent of relieving Metro Manila of its overdependence on the water supplied by Angat Dam. Most of these have focused on a particular site in Barangay Laiban in Tanay, Rizal, on the upper portion of the Kaliwa River Watershed to which the Laiban Dam belongs, and the projects have thus often been referred to as Laiban dam or Kaliwa dam, although multiple projects have been referred to using either name.
Metro Manila, the capital region of the Philippines, is a large metropolitan area that has several levels of subdivisions. Administratively, the region is divided into seventeen primary local government units with their own separate elected mayors and councils who are coordinated by the Metropolitan Manila Development Authority, a national government agency headed by a chairperson directly appointed by the Philippine president. The cities and municipality that form the region's local government units are further divided into several barangays or villages which are headed by an elected barangay captain and barangay council.

The Angat Watershed Forest Reserve is a conservation area that protects the drainage basin in the southern Sierra Madre range north of Metro Manila in the Philippines where surface water empties into the Angat River and its distributaries. It is spread over an area of 62,309 hectares in the eastern portion of Bulacan and northern Rizal province at an altitude of between 490 and 1,206 metres. The conservation area also extends to the provinces of Nueva Ecija and Quezon and is centered on an artificial lake created by the Angat Dam which, together with the Ipo Dam located 7.5 kilometres (4.7 mi) downstream, supply 97% of the water requirement of Metro Manila via an aqueduct system to the La Mesa Dam and Reservoir and the Balara Filtration Plant in Quezon City. The Angat Dam and Reservoir is also a major source of hydroelectricity for Metro Manila and surrounding provinces, contributing some 200 megawatts to the Luzon grid. The watershed is a popular birdwatching site and is a biodiversity hotspot containing most of the remaining closed-canopy forests in Central Luzon.
The Pantabangan–Carranglan Watershed Forest Reserve is a conservation area located in the upper reaches of the Pampanga River in Nueva Ecija, Philippines, and borders the Sierra Madre and Caraballo Mountains in Aurora and Nueva Vizcaya. It encompasses 84,500 hectares of the drainage basin surrounding the Pantabangan Lake, an impoundment of the Pampanga River by the Pantabangan Dam. The multi-purpose dam is situated at the confluence of Pampanga River's two headwaters, namely the Pantabangan and Carranglan Rivers in the municipality of Pantabangan. It stretches above the dam site for 21 kilometres (13 mi) to where Carranglan River originates in the Caraballo on the north, and for 18 kilometres (11 mi) to where Pantabangan River originates in the Sierra Madre on the east. It is considered a critical watershed for the agricultural economy and hydroelectric power generation in the region of Central Luzon.
West Avenue is a major road located in Quezon City within the Diliman area of northeastern Metro Manila, Philippines. It runs north–south through the western edge of the barangay of West Triangle. The street is located in Quezon City's commercial-residential area, known for its restaurants, car shops, schools, and villages. It is also home to the old Delta theater located on the avenue's junction with Quezon Avenue. The avenue is a component of National Route 171 (N171) of the Philippine highway network.
The Umiray–Angat Transbasin Project (UATP) is an expansion project of the Metropolitan Waterworks and Sewerage System (MWSS) for the supply of the Angat Dam reservoir. The 13-kilometer-long (8.1 mi) 4.30-meter (14.1 ft) diameter tunnel-aqueduct system diverts waters from the Umiray River east of the Angat Basin. 20–30% of the water that is consumed in Metro Manila and its outlying regions is supplied by the Umiray Basin.
