Stations were mapped by Trimble differential GPS on ArcView GIS software to enable precise replication by future investigators. Longitudinal analysis showed a trend of increasing eutrophication going downstream. Much of this effect was reversed by the wetlands mauka of He'eia Fishpond. However, dissolved oxygen was severely depleted, presumably by detritovors feeding off of leaf litter in the mangrove forest at Long Bridge. Measured variables in the tidal estuary section of the stream showed very complex patterns due to inputs from both marine and aquatic waters.
Further study is indicated to enhance understanding of the estuary.
More stations are needed to properly analyze the separate effects of the marsh and mangrove swamp.
