' The erosion condition composi te SSF score for this site was 7, which placed it in the
Stable erosion class. The tabulated res ults for this survey are conta ined in Table 20. There are
minor rills and small gullies that appear to be stable. Corrective measures planned as a result of
' this inventory include contour furrowin g and seeding gullies located at the southwes t edge of the
