Pasig River in Philippines

Pasig River in Philippines links Laguna de Bay to Manila Bay enroute the Napindan Channel. In Filipino language, Pasig River is known as Ilog Pasig. Metro Manila is separated into two cross-sections by River Pasig that extends for 25 kilometers with two most important streams # the Marikina River and San Juan River.

Interestingly enough, Pasig River in Philippines reflects the nature of a tidal estuary. It means that the direction of the water current is decided by the difference of the water level between Manila Bay and Laguna de Bay. If you notice during the dry season, you will find that the water level in Laguna de Bay is low and hence the water current of the Pasig River will be influenced by the tides. However, when the water level of Laguna de Bay is high in the wet season, the current flows from Laguna de Bay towards Manila Bay.

When there was Spanish colonial rule in Manila, Pasig River in Philippines was known as one of the most important routes of communication and transit. With gradual passage of time, the river was dumped with toxic pollutants leading to death of the bio-diversity of the river. It so happened that at one point of time, Pasig River failed to support any life form and inspired the formation of the Pasig River Rehabilitation Commission to cleanse the river of pollutants and regulate its condition.
