LLDA was organized by virtue of Republic Act No. 4850 as a quasi-government agency with regulatory and proprietary functions. Through Presidential Decree 813 in 1975, and E.O. 927 in 1983, its powers and functions were further strengthened to include environmental protection and jurisdiction over the lake basin’s surface water. In 1993, through E.O. 149, the administrative supervision over LLDA was transferred from the Office of the President to the DENR.
