• a given site to be documented. Technical Note No. 346 is provided in Permit No. C-80-001 as <br />MONITORING INFORMATION <br />Appendix 4.3-B. <br />The condition of the individual flow features previously mentioned were measured using <br />method 1 ("Cross-Section Survey") outlined in Permit No. C-80-001, Section 4.3. This method <br />was chosen to determine the rate of degradation or agradation within these reaches over time. <br />The stability of the hillslope was measured using a modification of the individual feature <br />method. In this case, a reference stake was placed on each side of the suspected movement area <br />with two stakes placed in the monitored area to form astraight-line transect. Any offset of the <br />center stakes was then noted. Two [ransects were placed on the hillslope to determine if any <br />differential movement within the suspect hillslope occurred. <br />MOFFAT AREA SUMMARY <br />Ten separate blocks aze designated in the Moffat Area. These areas are shown on Exhibit <br />1, Sheet I of 2, of this report. Table 1 provides a summary of the inventory data and is followed <br />by a brief description of each area and the corrective measures performed on each block as a <br />result of previous inventories. The numerical value for each block represents the composite <br />erosion condition soil surface factor (SSF) score as determined by the inventory methods. <br />All of the blocks scored in the stable category during this survey. The relatively low <br />values were impart due to increased vegetative cover and a lack of surface runoff during the <br />spring snowmelt. The lack of surface runoff resulted in little or no soil movement or surface <br />litter movement. <br />Table l: Moffat Area Erosion Inventory Data Summary <br />Area 1998 1997 1996 1995 1993 <br />Block) l2 18 17 22 9/40* <br />Block 2 6 l2 26 18 6 <br />Block 3 12 18 21 23 <br />Block 4 12 18 18 26 6 <br />Block 5 6 9 21 32 6 <br />Block 6 9 IS 24 26 <br />Block 7 9 24 20 43 <br />Block 8 9 25 24 43 <br />Block 9 6 24 30 37 <br />Block 10 9 36 <br />• This area was sub-divided into two sections during the 1994 inventory. <br />Block 1 contains live-handled roto-cleazed topsoil (1992) that did not receive additional seeding <br />as a test block for the reintroduction of native plant species on live-handled roto-cleazed topsoil. <br />• Repair of single gully on northern portion of Block (1994). <br />•• A portion of the northern section of Block received interseeding in 1995 as described in the <br />1995 Annual Reclamation Report. <br />
