Heeia Stream Water Quality Monitoring

Site 8:  The Stream Mouth

Our last sampling site is at the mouth of the stream as it empties into Kaneohe Bay. It has a natural bottom that is a mixture of silt and sand. One of the banks is the mangrove-infested wall of Heeia Fishpond, and the other is a natural bank covered with native and alien vegetation. Mangrove (Rhizopora mangle and Bruguieria sexangula), Indian pluchea (Pluchea indica), Milo (Thespesia populnea) and Hau (Hibiscus tiliaceus) are the predominant species growing in the area. Commonly observed animals in the stream include: juvenile Aholehole (flagtail, Kuhlia sandvicensis), juvenile ‘Ama‘Ama (mullet, Mugil cephalus), juvenile ‘O‘opu ‘Akupa (goby, Eleotris sandwicensis), Opae and juvenile Kuhonu (haole crab, Portunus sanguinolentus).

Dissolved oxygen levels, water temperature and pH increase from the previous site while Biochemical Oxygen Levels (BOD) decrease slightly.
