Due to the extremely dry year experienced in 1996, vegetative cover on both the dryland <br />reclaimed and reference areas was lower than previous year's sampling data. Rock content <br />observed on the reference area contributed significantly to overall cover versus the rock <br />content observed in the reclaimed area soils. While vegetative cover was better on the <br />reclaimed areas than on the reference area, rock content make the use of reference area <br />comparisons invalid. Use of pre-mining data indicates that post mining runoff would be less <br />than the pre-mining conditions. <br />7. NORTH FLAT AREA <br />7.1 Area <br />' The North Flat Area is a bench on the north end of the top of the hill. A portion of the <br />area served as a top soil storage area. In this demonstration, the area is divided into two <br />parcels, one west of Ditch 3N1 (2.32 acres) and one east (0.98 acres). <br />7.2 Network and Configuration <br />' 7.3.1 Pre-Vfining State <br />No large scale mapping or small contour interval mapping is available of the area that <br />portrays pre-mined conditions. From the small scale mapping available (USGS Chimney <br />Rock 7.~ Minute Quadrangle), the area drained to the east. Once off the top flat area, the <br />runoff was down steep slopes into Stollsteimer Creek. In this demonstration, the runoff <br />captured by Ditch 3N1 (the area west of the ditch) is compared with reclaimed conditions. <br />and the runoff from areas east of Ditch 3N1 (not captured by Ditch 3N1) is compared prior <br />to discharge over the steep east-facing slopes. <br />' 7.2.2 Reclaimed State <br />As for the pre-mining state, the runoff captured by Ditch 3N1 (the area west of the ditch) <br />is compared with pre-ming conditions, and the runoff from areas east of Ditch 3N1 (not <br />captured by Ditch 3N1} is compared prior to discharge over the steep east-facing slopes. <br />Once Ditch 3N1 is reclaimed, all runoff will be towards the east, similar to pre-mining <br />conditions. <br />7.3 Soils <br />' The area is on Carracas Loam <br />7.4 Land Use Condition (LUC) <br />' Reference is made to Paragraph 2.4. <br />' Page 25 of 34. 7 Oc[ 96 <br />t <br />
