in the Philippines
. It is one of 21 River tributaries of Laguna de Bay

visited Pangil when he was still a prince, and it was said that he used to frequent river often.
When he was crowned king, he sent the images of the Santo Niño de la O and the Birhen de la O to Pangil in gratitude. the Birhen de la O, which shows a pregnant Virgin Mary, is believed to be miraculous.
It also indicated that this status had been "maintained" since the river was last monitored.
According to the Water Usage & Classification for Fresh Water system used by the Philippines' Department of Environment and Natural Resources, Class D Quality freshwater is suitable for agriculture, irrigation, livestock watering and industrial water supply class II. "Worse than Class D" implies that the Pangil River is not suitable for any of those functions.
In 1980, International Rice Research Institute
(IRRI) researcher DA Vaughan documented six populations of Oryza minuta Presl. - a wild rice species known to be resistant to bacterial blight, bacterial blast, green planthopper, and brown planthopper
- along a stream which is a tributary of the Pangil river.
A 2004 survey noted with alarm that all the populations were gone. The report attributed the disappearance of the rare and useful species of rice to human activities, particularly "livestock raising, farming, and road construction, which destroy the natural vegetation within the vicinity."
Scientists have noted that further studies are needed to prevent the local extinction of this species.
