Watershed Restoration in KRIS Ten Mile

Erosion Control/Road Decommissioning :

The Hawthorne Timber Company is planning an extensive program of erosion control related to roads in the Ten Mile River basin (Steven LaVesque, personal communication). This will include a major effort to inventory all potential sources of erosion in basins that still harbor coho. Implementation will follow as soon as cooperative funding sources are available. A pilot project was the removal of a hanging, under-sized culvert on O' Conner Gulch, depicted below. All photos courtesy of Hawthorne Timber Company.
