Wheatfield Fork Subbasin Overview
The Wheatfield Fork Subbasin has 246 miles of “blue line” stream in a watershed area of 111.6 square
miles in the middle and eastern portion of the Gualala River Watershed. The mélange of the Franciscan
Complex predominates in the eastern portion of the subbasin. About 60 percent of the subbasin is
categorized as high to very high landslide potential. Most of the subbasin is privately owned (166 acres
of federal land), with land uses in timber production, grazing, vineyards, and some rural subdivisions.
