Angat Dam is a concrete water reservoir embankment hydroelectric dam that supplies 90 percent of the raw water requirements for Metro Manila. The reservoir supplies about 90 percent of raw water requirements for Metro Manila through the MWSS and irrigates thousands of hectares of farmland in Bulacan and Pampanga. The dam impounds water from the Angat River which subsequently created the Angat Lake. Visitors can get a pretty nice view of the dam, river and lake from the view deck of the Angat Rainforest and Eco-Park in Norzagaray, Bulacan or explore the other areas right beside the lake. The whole area of Angat Dam is a refreshing destination for bikers and road-trippers.
