Project and Dam of the National Power Corporation (NPC or Napocor) in Norzagaray. The heavy downpour caused the water in the dam reservoir to rise perilously to a danger height of 212 meters above sea level. Napocor opened the spillway gates to

The
Engineering Construction, Inc. (ECI), which had been doing construction work also in Norzagaray, suffered losses to its equipment and properties when the extraordinary large volume of water rushed out of the spillway gates and hit ECI's installations and construction works.

As of 2010, Angat Dam was providing 4,000 million liters a day (mld) out of a demand of 4,395 mld, and that demand was expected to grow to 5.054 mld in 2015, and 4,680 mld in 2020. Successive administration have already pushed for additional sources, such as the
