South Subbasin Overview
The Southern Subbasin is located south of Bridge Creek (RM 52.1) and McKee Creek (RM 52.8), both near Thorn Junction, and continues upstream to the Mattole’s headwaters near Four Corners (RM 61.5), a distance along the mainstem Mattole of about 9.4 miles. The subbasin is 86% privately owned and is largely managed for timber production and rural subdivision. The Southern Subbasin supports populations of Chinook salmon, coho salmon, and steelhead trout. Except for dewatered channels and low flows in summer, this subbasin currently contains the best salmonid habitat in the Mattole Basin.
