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. The park is under the joint administration, supervision and control of 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 Arroyo.



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. 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. 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. 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.


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.

The most common tree species found in the reservation are Malay beechwood, earleaf acacia, acacia mangium, narra, mahogany, teak, ipil-ipil, alibangbang and bangkal.
