The canal is a drainage system that serves as a flood control measure for the Manoa and Palolo valleys. The flow is provided by runoff from rainfall and stormwater in the surrounding areas, and is affected by seasonal trends such as the rainy season. The canal is not connected to any specific tributaries or dams. An interesting fact about the hydrology of the area is that the Manoa Valley is one of the wettest places on earth, receiving an average of 350 inches of rainfall per year.
