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]
