Laguna de Bay is the largest lake in the Philippines and third largest freshwater lake in Southeast Asia. It is surrounded by the provinces of Laguna and Rizal, and also Metro Manila (Pasig, Taguig and Muntinlupa). It is around 76,000 hectares and has a volume of 3.2 billion cubic meters. The lake is an important source for fishing, for irrigation and for domestic water needs; it is also a temporary reservoir. It is used as a transport route but still can be further developed.
