River Basin Profiles


Agusan River Basin

Next to the Mindanao River Basin, Agusan River Basin (ARB) is the third largest river basin of the Philippines. Located in the northeastern part of Mindanao, its drainage area measures 10,921 km2. It covers the Agusan Marsh, which is a wildlife sanctuary.

The Agusan River passes mainly through three provinces in Region XI and Caraga.  The River originates from the slopes of Davao Oriental, traverses northward through Compostela Valley, Agusan Marsh in Agusan del Sur, and Agusan del Norte, before draining into Butuan Bay.


“The Agusan River Basin is envisioned as an edifice of a peaceful, prosperous and empowered citizenry with equitable wealth seated on a well-managed and balanced ecology for sustainable agro-industrial and eco-tourism development.” 


“Poverty reduction and enhanced livability in the Basin by the year 2020 through the optimal development and sustainable use of Agusan River Basin resources according to an Integrated River Basin Management (IRBM) approach founded on unified governance, demand-based and high-impact interventions, and effective knowledge database development.”



Agus-Ranao River Basin

The Power Source of Mindanao

The Ranao (Agus) River Basin is bounded on the north by Iligan Bay, Bukidnon province on the east, Maguindanao and North Cotabato provinces on its south and Illana Bay on its southwest. It has a total land area of 1,987.07 km2 consisting of five major subwatersheds which supply water to Lake Lanao. Agus River serves as the drainage of Lake Lanao. Also, it is a hydropower source for Mindanao.

“A well-protected and developed river basin providing a steady supply of water resources to power the industries and the hydro-electric power plants in the area.”


“To institute and implement programs  and projects to ensure the sustainable supply of water while adopting to the impact of climate change.  (Proposed as of drafting the AVP)”

Mindanao River Basin

Mindanao’s Life Source

The Mindanao River Basin is the second largest river system in the Philippines, and the largest in Mindanao. Located in the Central and a portion of Southern Mindanao, it has a total catchment area of 21,503 km2. It is also the largest bird sanctuary in Mindanao and a habitat of crocodiles.

It covers the area from the mountains of Impasug-ong in Bukidnon (known as Upper Pulangi River), Kabacan River (relabeled as Mindanao River), Lower Pulangi River and Ligawasan Marsh. The latter serves as natural flood storages, from which the river system splits to the Tamontaka and Rio Grande de Mindanao Rivers and finally exits to Illana Bay.


“A Mindanao River Basin that is a sustainable area of peace and development where all stakeholders, striving as active collaborators and competent stewards of the Almighty Creator, adhere to the judicious use of its natural resources to enjoy non-discriminatory socio-economic growth, human development and ecological balance that is inclusive for all and without aggression to anyone or anything.”
