English: Canili and Diayo Dams and Reservoirs, Maria Aurora [1] (Manmade Structures Dams, Coordinates (WGS84) 15° 47.351N 121° 19.066E Elev: 309m)[2][3]. The four-decade old dam is a tributary of Pantabangan Dam that irrigates more than 100,000 hectares of farmlands in the provinces of Pampanga, Nueva Ecija, Tarlac and Bulacan in Central Luzon. Diayo dam, which was simultaneously built along with Pantabangan Dam in 1970s, was designed only for light vehicles. The dam has been transformed into a major part of BPR when Baler-Bongabon road, then a major road network linking Aurora to Nueva Ecija, was devastated by a series of typhoons in 2004. The Dams are situated in the deep canyons of the Canili and Diayo rivers in the Baler-Aurora basin. The confluence of the two rivers is about 800 meters downstream of the Canili damsite where it forms the Cabatangan River, which flows east to the town of Baler and empties into the Philippines Sea.[4]
