"Río Grande de Mindanao (o simplemente Río Mindanao) es el segundo mayor sistema fluvial en Filipinas, después del río Cagayán de Luzón."
"The Rio Grande de Mindanao, also known as the Mindanao River, is the largest river system in the Philippines,. It is the largest river on the southern island of Mindanao with a drainage area of 23,169 km2 (8,946 sq mi) draining majority of the central and eastern portion of the island. It is also the second longest river in the country with a length of approximately 373 km (232 mi). It is an important transportation artery on the island, used mainly in transporting agricultural products and, formerly, timber. Its headwaters are in the mountains of Impasugong, Bukidnon, south of Gingoog City in Misamis Oriental, where it is called the Pulangi River. Joining the Kabacan River, it becomes the Mindanao River. Flowing out of the mountains, it forms the center of a broad, fertile plain in the south-central portion of the island. Before its mouth in the Moro Gulf, it splits into two parallel sections, the Cotabato and Tamontaka, separated by a 180 m (600 ft) hill. Population centers along the river include Cotabato City, Datu Piang, and Midsayap."
