The following are field names and definitions for the GIS attribute table of the river bars of the Middle Rio Grande, from Belen to San Acacia. This appendix lists all the fields in the attribute table with their definitions. It also provides lists of the discrete value codes and their definitions for applicable fields. Boldface type indicates field titles present in the table. Boldface type in parenthesis indicates codes used in the table for discrete variables.
