Pantabangan Dam is an earth-fill dike dam on the Pampanga Stream situated in Pantabangan in Nueva Ecija area of the Philippines. The multi-reason dam gives water to water system and hydroelectric force age while its supply, Pantabangan Lake, bears flood control. The supply is viewed as one of the biggest in Southeast Asia and furthermore one of the cleanest in the Philippines. Development on the dam started in 1971 and it was finished in 1974.

History
In May 1969, the Congress of the Philippines approved the advancement of the Pampanga Bowl with Republic Act No. 5499. In October of that year, nitty gritty investigations of the Pantabangan site were done and kept going two years. By June 11, 1971, Pantabangan was an old town of around 300 years of age. President Ferdinand Marcos and numerous others showed up for a historic service in Palayupay, Pantabangan, Nueva Ecija, to flag the start of the development of Pantabangan Dam.The dam went into activity in February 1977 and was finished later in May. Roughly 1,300 individuals were moved from the dam's supply zone.
Plan
The dam is a 107 m (351 ft) tall and 1,615 m (5,299 ft) long dike type with 12,000,000 cu yd (9,174,658 m3) of homogeneous earth-fill and an impenetrable center. The peak of the dam is 12 m (39 ft) wide while the vastest aspect of its base is 535 m (1,755 ft). The dam's peak sits at a rise of 232 m (761 ft) and is made out of three segments: the principle dam, a seat dam, and an assistant dam situated with the spillway. The spillway is a chute-type constrained by three spiral entryways yet outfitted with a flood segment also. The plan release of the spillway is 4,200 m3/s (148,322 cu ft/s). The dam's supply has a gross limit of 2,996,000,000 m3 (2,428,897 acre⋅ft) and 2,083,000,000 m3 (1,688,716 acre⋅ft) of that volume is dynamic (or valuable) for water system and force. The dam sits at the top of a 853 km2 (329 sq mi) catchment region known as the Pantabangan–Carranglan Watershed Woods Save and its store has a surface territory of 69.62 km2 (27 sq mi) and height of 230 m (755 ft) when at its most extreme level. The store's life is assessed at 107 years because of residue from denudation.The dam was intended to withstand a power 8 quake.
The force to be reckoned with is situated at the base of the fundamental dam and contains two 60 MW Francis turbine-generators for an introduced limit of 120 MW. Every turbine gets water through a 6 m (20 ft) breadth penstock. At the point when the water is released, it is delivered into a 250 m (820 ft) long tailrace channel where it reenters the waterway.
