waimanalo stream monitoring station

The Waimanalo Stream is on the windward side of Oahu. Waimanalo means “potable water.” Despite the relatively wet climate for which the windward side of the island is known, Waimanalo recieves far less precipitation than the areas of Kailua and Kaneohe. Consequently, low streamflow occurs more frequently. This and a combination of other factors give rise to a rather interesting hypereutrophic ecosystem including algae and ferns that line the channelized portion of the stream. A variety of small fishes and gastropods occur in abundance. Mats of aezolla also canvas the surface of parts of the stream that are back watered. Downstream, dense vegetation includes cane which often chokes the stream causing water to backup.

This study has been concluded and the conclusions will be posted at a later date.
