Waikele Stream at Waipahu

USGS site 16213000

Waikele Stream at Waipahu

Waikele Stream at Waipahu

This mixed land-use site is near the mouth of Waikele Steam (altitude 1.37 ft) in central Oahu and has a drainage area of 45.7 square miles. The upper 28 percent of the drainage is largely forested (conservation) land. The lower 72 percent of the drainage is agricultural (47 percent) and urban (25 percent) land. A continuous record of streamflow has been collected at this site since 1960. This site was part of the fixed-site network for water-column studies during the period March 1999 through February 2001. Bed-sediment and fish-tissue samples were collected as part of an occurrence survey of trace elements and hydrophobic organic compounds in the fall of 1998. In addition, ecological studies were conducted at this site in the summer of 1999.
