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 September 23, 1972. The issuance also integrated all irrigation activities under the Agency. The Administrative Code of 1987, dated July 25, 1987, attached 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 September 14, 1992. Then, it was attached to DA under Administrative Order No. 17, dated October 14, 1992.
