Lower Agno Watershed Forest Reserve

The Lower Agno Watershed Forest Reserve is a Philippine protected area that straddles the Cordillera and Ilocos regions encompassing land from the provinces of Benguet and Pangasinan. Operated by the Lower Agno WFR Protected Area Management Board under the Department of Environment and Natural Resources, Lower Agno follows the Agno River corridor from the northern villages of Itogon to just north of the municipalities of San Manuel and San Nicolas. The reserve also known as the San Roque Watershed protects the mid-Agno River basin with its meandering river and short tributaries in a pine-forested mountainous terrain at the southern end of the Cordillera Central, around 30 kilometres (19 mi) southeast of Baguio. It is located in an important mining district and includes the reservoir of the San Roque Dam, the largest dam in the country and the prime source of water, hydropower and irrigation for surrounding regions in Luzon.
