Surface Drainage

Alaminos City has its own riverine system, the Tagoong River, with a length of approximately 10 kilometers, stretching from the Embarcadero  Bridge going downstream to the mouth of Tambac Bay. Several minor rivers, creeks and swamps are also  distributed within the city, with  an estimated  area of 613.766 hectares or 3.7% of the total land area.

These river serves as source of fresh water for irrigation agricultural  lands as well as an alternative transport access, using both non-motorize and motorize boats as means of transportation, particularly from Poblacion heading out downstream towards  Barangay San Jose that futher exits to the  mouth of  Tambac Bay via Barangay Mona or  Barangay Pangapisan.
