About the Project

Efficient information sharing of watershed acquired, existing, and processed data for planning, development, and management of projects and aide in decision making process through interactive map and collaborative information sharing

What is a Watershed?

Watershed is a basin like system, topographically delineated area that collects rain water and drains into rivers to a common outlet such as dams. A watershed is commonly composed of headwater, drainage area and an outlet. The headwater is the highest portion of the watershed where the rivers ends. The drainage area is where water from precipitation is collected. And the outlet where the water drains into the sea, a major river or in an infrastructure such as dams and weirs. A watershed is a complex system in which humans interacts with natural resources.

iWatershed Objectives

The innovative way of storing and accessing spatial data and information about watersheds with Hydropower facility

Establish an information and data storage system for hydropower watersheds

Access data and information that will feed into hydropower watershed management and project development

Provide visual presentation of information and data

Efficiently provide reports, processed maps, GIS data and other relevant information about hydropower watersheds

Information sharing and monitoring of sustainability and CSR projects through mapping and geotagging

Generate real-time information on watershed hydrology for water balance estimates, sediment yield, modelling and other relevant information

Synthesis and analysis of spatial data for prediction, scenario building and modeling of vital processes in the water management, dam operation and watershed monitoring

Build capacity to use watershed information in the decision making process

Watersheds

Ambuklao-Binga Watershed

The Ambuklao-Binga Watershed, also known as the Upper Agno Watershed, is the headwater of the Agno River Basin watershed situated in the Cordillera Administrative Region, Northern Luzon. Geographically, it is located between 160 18’ 40.76” to 160 18’ 19.04” latitude and between 1200 54’ 20.82” to 1200 55’ 5.15” longitude. The watershed is within the province of Benguet and some portions of the adjoining provinces of Mountain Province and Nueva Vizcaya. It is bounded on the north by Buguias, Mountain Province, on the south by the municipality of Itogon, Benguet, on the east by municipality of Kayapa, Nueva Vizcaya and on the west by Municipality of Atok, Benguet. ..

Magat Watershed

The Magat Watershed, is the headwater of the Cagayan River Basin watershed situated in the Northern Philippines within the Cordillera Administrative Region and Region II. Geographically, it is located between 160 06’ 22.05” to 170 02’ 56.14” latitude and between 1200 48’ 60” to 1210 28’ 11.87” longitude. The majority of the watershed is within the province of Ifugao and Nueva Vizcaya and some portions of the adjoining provinces of Isabela, Benguet and Mt. Province. It is bounded on the north by Mountain Province and Ifugao, on the south by the province of Nueva Ecija, on the east by Benguet and on the west by Provinces of Isabela and Quirino.

It is the home of the 380 MW Magat Hydropower plant in Ramon, Isabela. Magat Watershed is classified as critical watershed due to its role in providing irrigation and power supply. NIA and NPC under Proclamation 573 manages and protects the Magat Watershed Forest Reserve. Also within the Magat Watershed lies protected areas such as the Salinas Natural Monument, Dupax Watershed Reservation, part of the Mt. Pulag National Park, Casecnan Protected Landscape and buffers of the Upper Agno River Basin Resource Reserve and Quirino Protected Landscape, including the Ifugao Rice Terraces.
