| Project Name: | Waiakea Stream Best Management Practices |
| ASO Log No.: | 97-321 |
| Start/End Date: | June 1997 through June 2000 |
| Federal Funds: | $90,000 |
| Matching Funds: | $60,000 |
| Contractor: | Jiro A. Sumada County of Hawaii, Department of Public Works 25 Aupuni Street, Room 202 Hilo, Hawaii 96720 Phone: (808) 961-8327 Fax: (808) 969-7138 |
| Background/ Overview: |
The water quality problem in the Waiakea Stream is caused by both natural and manmade factors. During heavy rains the stream is extremely turbulent due to its winding path, undulating bed, and woody bank vegetation. This results in stream bank erosion and the transport of sediment downstream, resulting in sedimentation of Waiakea Fishpond and Hilo Bay. |
| Objectives/Goals: | To reduce NPS pollutants into the watershed by implementing a structural measure on Waiakea Stream and an educational measure to educate residents on adjacent lands. |
| Methods Employed: | • Construct a structural measure to stabilize the bank
along a stretch with a history of sloughing and severe erosion • Provide a filtering mechanism for storm runoff into the stream • Conduct a workshop to discuss NPS pollutants, the project, and their involvement as residents living adjacent to the project |
| Pollutants of Concern: | Sedimentation |
| Watershed: | Wailoa Watershed, island of Hawaii |
| Size of Project: | Not described in report |
| Affected Water Bodies: | Waiakea Stream, Wailoa Channel, Waiakea Fish Pond, Hilo Bay |
| Deliverables: | None |
