The National Irrigation Administration (NIA) is a government-owned and controlled corporation primarily responsible for the irrigation development and

management. It was created under Republic Act (RA 3601) on 22 June 1963. Its charter was amended by Presidential Decree (PD) 552 on 11 September 1974 and

PD 1702 on 17 July 1980. Both increased the capitalization and broadened the authority of the Agency. NIA's forerunner was the Irrigation Division of the defunct

Bureau of Public Works. NIA was placed under the Office of the President (OP) upon its creation. It was attached to the Department of Public Works,

Transportation and Communication under PD No. 1, dated 23 September 1972. The issuance also integrated all irrigation activities under the Agency. The

Administrative Code of 1987, dated 25 July 1987, atatched NIA to both the Department of Public Works and Highways (DPWH), and Department of Agriculture

(DA). But NIA remained attached to DPWH. It was transferred to OP pursuant to Executive Order No. 22, dated 14 September 1992. Then, it was attached to DA

under Adminsitrative Order No. 17, dated 14 October 1992.
