Caption:  This Chart Table sediment_road_nav_fcrei_00_01.dbf shows potential erosion related to Mendocino County roads in the Navarro River watershed, based on road survey data collected in the years 2000 and 2001 as part of the Five Counties Road Erosion Inventory. Data were collected by the Mendocino County Department of Transportation, with training and protocol design by Pacific Watershed Associates.

A key to column headings: COUNT = Number of sites in each PROBLEM category, EPIS_EROSN = Episodic erosion (sudden major events), DECD_EROSN = Decadal erosion (chronic surface erosion), TOTL_EROSN = Sum of EPIS_EROSN and DECD_EROSN.
