Magat River Integrated Irrigation System

The Magat River Integrated Irrigation System Project, started by the National Irrigation Administration in the 1960s, is one of the Philippine's largest irrigation projects with hydroelectric power generation capacity. Its total cost amounted to US$500 million.[1]

The project is made up of the Magat reservoir, three diversion dams, a large number of irrigation canals and three pumping stations to supply irrigation water for an area of about 97,400 hectares (974 km2). It is also includes hydroelectric power plants; 360 megawatts (480,000 hp) at Magat reservoir, 6,000 kilowatts (8,000 hp) at Baligatan and 2,500 kilowatts (3,400 hp) Magat mini-hydroelectric power plants in Maris main canal.
