| Project Name: | Lanai Watershed Restoration |
| ASO Log No.: | 01-193 |
| Start/End Date: | October 2001 to December 2004 |
| Federal Funds: | $50,000.00 |
| Matching Funds: | $50,000.00 |
| Contractor: | George Tengan Department of Water Supply, County of Maui 200 South High Street Wailuku, Maui, Hawaii 96793 Phone: (808) 270-7816 Fax: (808) 270-7833 Darrell Stokes |
| Background/ Overview: |
Loss of vegetative cover on Lanai has led to severely eroded landscapes, with soil loss estimates upwards of 2,200 tons per year on the 200 acres of denuded lands in the target area alone. This progressive loss of cover and of soil can also be expected to result in tremendous sediment burden to nearshore waters. These problems are exacerbated by high fire hazard conditions in certain area. Drinking water is also threatened by the loss of forest cover. Lanai has the smallest sustainable yield of any of the 6 major islands. |
| Objectives/Goals: | The project will restore the Lanai Watershed by preventing further loss of soil and reducing nutrient loads of near shore waters through planting ground cover, installing fencing, and removing weeds that increase fire hazard or that does not provide good erosion protection. Several miles of fencing trails have been cleared and installation of fencing materials has begun. Educational presentations have been developed and the contractor is currently presenting the information to local schools and the community. The project is also developing movie ads to inform the general public about nonpoint source pollution and other issues facing the island of Lanai. |
| Methods Employed: | • Survey/design fence line and develop survey report • Propagation and planting of vegetative cover • Weed removal from selected areas • Construction of soil-holding wattles from selected areas • Public education through service trips and school projects |
| Pollutants of Concern: | Sediment burden to near shore waters |
| Watershed: | Lanaihale, from Maunalei to Awehi Watershed |
| Size of Project: | 3,600 acres |
| Affected Water Bodies: | Pacific waters of the northeastern side of Lanai |
| Deliverables: | • Final Report • Aerial and ground photos of fence line survey • Photos of before, after and 6-month follow-up of plantings, weed removal, wattle construction |
