Most of the problems in life are because of two reasons: we act without thinking or we keep thinking without acting. –Unknown
Where the Mānoa Stream and the Pālolo Stream meet, you can easily compare, with a naked eye, the murkiness of the Mānoa Stream to the clarity of the Pālolo Stream. Where the streams meet, the site of our field research, is in a residential area. There is no public parking. If you visit this site during mid-day, perhaps bring some earplugs and a bottle of water, and also wear a good pair of walking shoes.

Mānoa Pālolo Drainage Canal
The lack of Gobi fish in the Mānoa Stream is an indication of an ecosystem problem that originates uphill in Mānoa. The culprit is the Albizia trees, which do not readily absorb much water. Thus, sheets of water pass over its roots and carry siltation. In other words, the runoff contains brown suspended matter that discharges into the Mānoa stream, and then flows down to the Ala Wai Canal, which ends up to be periodically dredged up!
Therefore, the Albizia trees in Mānoa is the root cause of the murkiness of the Mānoa stream, and thus, are a threat to the Ala Wai Watershed, namely Waikiki, which is downstream of Mānoa!
