Professor Eric De Carlo of the Department of Oceanography at the University of Hawai'i is part of a research project that studies the Manoa-Palolo Watershed.

Data is collected from a network of stations along the Manoa and Palolo stream system, the Ala Wai Canal, and Mamala Bay. This dot is the uppermost station located on Waiakeakua Stream at an elevation of 85 m.

"This relatively pristine stream combines with Wai Iki and several other small streams to form Manoa Stream, which runs through the residential community of Manoa. As Manoa Stream flows through the Manoa Valley it accumulates pollutants from runoff. Anthropogenic activity in the valley center leads to pollution which is carried into the stream. Increased vehicular traffic and urbanization near the University of Hawai'i, in Kaimuki and in Moiliili, as well as channelization, lead to degradation of the waters of Manoa and Palolo streams."
