The earthen and concrete dam that holds back water to form Ho`omaluhia Reservoir (Loko Maluhia) for flood control, also more or less marks the boundary between upstream, undeveloped and open land use (two golf course and major highways) and downstream, urban land use in this watershed. The change from forest to housing can be seen in Photo 16, taken from the top of the dam structure looking north into Kaneohe town. TMDL Station 1a at the base of the dam monitored the influence of the reservoir on Kamo`oali`i Stream water quality.
From the dam at Ho`omaluhia, Kamo`oali`i Stream is confined to a modified (lined and straightened) channel. The stream flows north, passing under Likelike Highway (State Rte. 63), then makes a broad turn eastward to pass under Kamehameha Highway (State Rte. 83) on it's way to Kane`ohe Bay (see Photo 15 above). Near the beginning of that broad turn, Kamo`oali`i Stream is joined by Kapunahala Stream (Photo 17) and the combined flows constitute the reach that takes the modern name of Kane`ohe Stream.

Kaneohe Stream has a second NAWQA water quality station (USGS station no. 16274100) in addition to the station on the Luluku branch. This station is located immediately downstream of the concrete culvert structure shown in Photo 18 below. The lined channel ends opposite the soccer park at Kaneohe Civic Center and from here to the mouth, Kane`ohe Stream flows over a natural bed, confined mostly between graded, soil banks.

Photo 18. Kane`ohe Stream beneath Kamehameha Highway (near the Kane`ohe Library) is confined within a massive concrete and crm culvert structure that spreads the flow out into a thin sheet of water. |

Photo 19. Most of the lower reach of Kane`ohe Stream is in a channel that is realigned, but lacks hardened, concrete bed or banks. Photograph taken near TMDL Sta. 5 |

Photo 20. The estuary of Kane`ohe Stream is a channel that is dredged from time to time. The Bay View Golf Course, seen here on the right bank, spans the estuary just upstream of the golf cart bridge. |
