Kalihiwai Reservoir built in 1920 is privately owned, not a public facility, that serves the community of Kalihiwai Ridge.  Its water is part of a gravity fed system serving its downstream neighbors in Kilauea on the North shore of the island of Kaua'i. It is listed as a wetland habitat with the USFWS. Of the five endemic endangered Hawaiian waterbirds, three live and breed at lakeside and enjoy the lake year round. Two, the stilt and duck, are currently only visitors.
