Block 8
The erosion condition composite SSF score for this site was 9, which placed it in the
Stable erosion class. The tabulated results for this survey aze shown in Table 9. The azea was
seeded in 1995 after the annual erosion inventory. The vegetation has established and is
controlling erosion. The bottom portion of this block contains inactive rills and gullies as
evidenced by vegetation on the sides and bottom. No corrective measures are planned as a result
of the inventory.

Block 9
The erosion condition composite SSF score for this site was 6, which places it in the
Stable erosion class. The tabulated results for this survey are shown in Table ] 0. The spoil
springs and seeps in this block have formed a system of small drainage channels. These channels
continue to stabilize with arniored bottoms and increased vegetation along the channel edges.
No corrective measures are planned as a result of the inventory.
