Among the 2.5-meter high, six-span dam’s main features are easily deflatable and inflatable rubber body, resistance to sedimentation, economical and having auto-deflation system.
Angat dam has a normal high water level of 210 meters, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa).
It has three gates opening a total of 1.5 meters to gradually release water that had accumulated due to incessant rains during typhoons.
In comparison, Ipo Dam, which is downstream from Angat dam, has three gates and the 100.8 meters is its normal high water level. Ambuklao dam on the other hand, has two gates with the normal high water level (NHWL) of 752 meters. Binga dam which sits downstream from Ambuklao has three gates and the NHWL of 575 meters. San Roque dam, which was receiving water from Ambuklao and Binga, has the NHWL of 280 meters.
Angat dam supplies potable water and energy to Metro Manila and nearby areas. Surrounded by lush greens, this place is also ideal for fishing, boating and hunting.
Built in 1926, 50 kilometers upstream from the Bustos Dam as a fixed type river weir without gates, the AARD, Angat Afterbay Regulator Dam (commonly known as Bustos Dam) is the longest rubber dam in Asia at 79 meters and the second largest in the world. It has coordinates of 14°57'25"N 120°57'15"E serving nearby cities: Real, Quezon, Rodriguez (Montalban), Rizal, Antipolo City, Rizal.
In 1967, steel sector gates were installed on top of the regulator dam for the purpose of generating irrigation water, power supply and domestic water supply.
