Description: Approximately 35 ft deep, this sand-bottom area off Hanalei Landing has been designated for a hundred moorings and is a popular summer anchorage.

Freshwater Inputs: Main freshwater source affecting the collection area is the Hanalei River though there are several small streams and an uncertain number of springs that also empty into the bay.

Collection Dates: 05.May.2000; 13.Aug.2000; 17.Jan.2001; 27.Apr.2001

Samples: Samples were collected at two locations: (1) Off the pilings of the Hanalei Landing, and (2) the inner reef area east of the Hanalei River mouth. The initial collection from both sites produced a wide variety of algae but the second collections, following heavy rains, revealed that almost nothing remained as reef zone, though many of the wharf specimens were still present, albeit in smaller quantities.
