 | This article needs attention from an expert in Hawaii or Rivers. The specific problem is: General expansion is needed considering that this is arguably the longest river in the Hawaiian Islands, but especially information on its discharge, watershed (including details on its source and mouth), navigability, and cultural significance is needed.

The Kaukonahua Stream
[1] or Kaukonahua River is a 9.9-mile-long (15.9 km)
[2] river on the island of
Oʻahu which is one of the
Hawaiian Islands. Including its longer South Fork, the stream's total length is 28.0 miles (45.1 km).
[2] It flows down in a generally northwest direction, from
21°30′7″N 157°54′13″W / 21.50194°N 157.90361°W into the
Pacific Ocean. The North and South forks meet at coordinates
21°29′44″N 158°5′50″W / 21.49556°N 158.09722°W.
[1] It is the longest river of the whole island group. It empties into Kaiʻaka Bay near
Waialua, Hawaii on the North shore.
However, the waters of Kaiaka Bay and the waterbodies that drain into it are known to be polluted with multiple contaminants that exceed State Water Quality Standards.
