A stabilization measures may be warranted. b) Mechanical treatments were applied to the long, steep spoil outslope below the ~1 Mine bench in February, 1996, in addition to broadcast seeding and mulching. This work was administered by the DMG Inactive Mines Program, using a portion of the forfeited reclamation bond. Prior to treatment, vegetation on the slope was limited primarily to cheatgrass, with a few annual forbs, and virtually no perennial plants. The mechanical treatment applied was extensive contour furrowing achieved by a dozer repeatedly backing up the slope and using the blade to cut intermittent furrows every few feet. The resultant roughened slope provides for water, seed and soil catchment, erosion control, and microsites for plant establishment. Following the mechanical treatment, the slope was broadcast seeded and straw mulched. A seedmix containing western, Siberian, and crested wheatgrass, Indian ricegrass, fourwinq and shadscale saltbush, winterfat, and rubber rabbitbrush was applied at a rate of 30 pounds per acre. The contour furrows have proven to be very effective in controlling erosion, and there is essentially no rill or gully erosion on the slope. The first year vegetation stand is still dominated by various annual forbs and cheatgrass, although numerous fourwinq saltbush seedlings are present. Due to the steep south facing aspect of the fill, combined with average annual precipitation of only 8 inches, the slope is a very harsh site for vegetation establishment. The stand will be monitored over the next couple of growing seasons, and re-treatment will be undertaken if warranted. c) As indicated above, there is essentially no rill or gully erosion on the steep fill outslope below the No. 1 Mine bench, although there had been some gullying prior to the mechanical treatment described. A few shallow rills exist on the backfilled slopes of the Mine No. 1 portals, but erosion is not excessive. There is no apparent rill or gully erosion on the Mine No. 2 backfilled slopes. There is one gullied segment along the main ephemeral drainage channel downstream from the culvert at the terminus of Diversion No. 1, adjacent to the base of the lower Mine No. 2 backfilled slope. The gullied segment is 50 to 60 feet in length, and up to 6 feet deep by 6 feet wide. A gully of this extent has apparently existed in this location since at least May of 1993, when it was described in an inspection report. Gully headcutting appears to have been arrested by a large sandstone boulder at its upper end, and there does not appear to have been recent downcutting, but this erosional feature will need to be monitored in future inspections. d) There is no evidence of recent sediment deposition in ditchgs or ponds. Damage to the terminal culvert on Diversion 1 hear resulted in sediment deposition in the ditch segment immediately above the culvert in the fall of 1995, but the culvert was repaired and the ditch cleaned out in March, 1996.
