Table 8: Moffat Area Block 7 Erosion Condition Classification <br /> Possible <br />Item Score 1997 1996 1995 1993 1992 <br />Soil Movement 14 3 3 8 <br />Surface Litter 14 3 0 3 <br />Surface Rock Fragments 14 0 2 5 <br />Pedestalling 14 0 0 3 <br />Flow Patterns 15 6 6 9 <br />Rills 14 8 3 9 <br />Gullies 15 4 6 6 <br />Total 100 24 20 43 <br />Erosion Condition Classi fication: Slight Stable Moderate <br />Block 8 <br />The erosion condition composite SSF score for this site was 25, which placed it in the <br />Slight erosion class. The tabulated results for this survey are shown in Table 9. This area was <br />seeded in 1995 after the annual erosion inventory. The young vegetation is helping to control <br />erosion. Tlie bottom area of this block contains some rills and gullies, but most have vegetation <br />on the sides and bottom. One gully system that exists just south of Downdrain 4 is active and <br />will require corrective measures consisting of grading in the gully system and reseeding the area. <br />Table 9: Moffat Area Block 8 Erosion Condition Classification <br />Possible <br />Item Score 1997 1996 1995 1993 1992 <br />Soil Movement 14 3 3 8 <br />Surface Litter 14 3 3 3 <br />Surface Rock Fragments 14 0 0 2 <br />Pedestalling 14 0 0 0 <br />Flow Patterns 15 3 6 12 <br />Rills 14 8 8 9 <br />Gullies 15 6 4 9 <br />Total 100 25 24 43 <br />Erosion Condition Classification: Slight Slight Moderate <br />Block 9 <br />The erosion condition composite SSF score for this site was 24, which places it in the <br />Slight erosion class. The tabulated results for this survey are shown in Table 10. Gullies exist in <br />the upper southern portion of the block resulting from gully activity in Block 10 along the <br />narrowed Lower Moffat Road. Additionally, the spoil springs in this block have caused a system <br />of gullies. Corrective measures in this block include repairing the gullies in the upper portions of <br />the block with a dozer and reseeding. The gullies associated with the springs will be repaired <br />and a collection ditch system will be installed to route the spring discharge [o the existing <br />drainage system in anon-erosive fashion. <br />
