Caption: The Source Table sediment_road_mill_mcrcdpwa_1998.db shows potential future sources of road-relation erosion in Mill Creek, based on phase 1 road survey data collected during 1998. Data were provided by the Mendocino County Resource Conservation District and PWA (1999). See Info Links for more information, including a full key to column headings.
