Upper Agno River Basin Resource Reserve

The Upper Agno River Basin Resource Reserve is a protected area located on the southeast flank of the Cordillera Central in the Philippine province of Benguet along its border with Ifugao and Nueva Vizcaya. It is a resource reserve located high in the Central and Polis ranges protecting the headwaters of the Agno River. According to section 4 of the National Integrated Protected Areas System Act (R.A. 7586), a resource reserve is an extensive and relatively isolated area designated as such to preserve the natural resources of the area. The reserve comprises 77,561 hectares (191,660 acres) of the catchment area that feeds the Ambuklao and Binga dams, two of the country's oldest hydroelectric plants that supply power to the city of Baguio and entire Benguet province. Upper Agno is north of and contiguous with the Lower Agno Watershed Forest Reserve that preserves the immediate downstream of the Binga Dam where the Agno River is impounded by a third dam, the San Roque Dam, the largest in the Philippines and the main source of water, electric energy and irrigation for surrounding regions in Luzon.
