Moffat Area Final Pit Ditch <br />This is the final down drain associated to Moffat Pond. This drainage appears stable, and is <br />designed wider than the previous drainages. The vegetation is well established. Minor rilling <br />has developed on the north side that runs to the channel (Photo 8794). Two noticeable gullies, <br />both approximately 30 yards long and 3 feet deep, have formed (Photo 8795). One gully has <br />boulders at top which were intentionally placed, indicating that some mitigation measures have <br />been taken. The other gully appears to heal itself at its base. <br />"Stringy of Pearls" (SOP) Check Dams <br />The first two check dams in the SOP are located on the south side of the West Ridge Road. The <br />spillway at Check Dam (CD) 2 has washed out creating a head cut that is approximately 1.5 feet <br />deep and six feet long before it encounters the rip rap (Photo 8797). Two 36" culverts connect <br />CD 2 to CD 3 under the road (Photo 8798). Large rip rap and boulders were utilized at this CD <br />location. <br />CDs 3 through 7 are dry with well established vegetation. The channels are lined with <br />geomatting below the check dams. At some CDs, the geomatting is exposed (Photo 8799). The <br />banks of these upper CDs are steeper with a narrower, well - defined channel. CD 5 has a steeper <br />bank that lacks vegetation (Photo 8800). Nick points begin to appear at CD 7 and get wider <br />towards the bottom CDs. CDs 8 through 11 increase in width as you approach the bottom of the <br />SOP. There are large areas that lack vegetation, and appear to have recently held water, as <br />evidenced by some wet ground areas and cracking in the "pond" bed (Photo 8801). <br />CD 12 was the only dam that contained water (Photo 8802). There is a shorter distance between <br />the rock channels of CDs 11 and 12 compared to other CDS. CDs 13 through 15 get much wider <br />near the bottom of the SOP. There are large areas that lack vegetation, and appear to have <br />recently held water, as evidenced by some wet ground areas and cracking in the "pond" bed. <br />CDs 16 through 21 contain vegetation (grasses), with each pond having more vegetation that the <br />last (Photos 8803 and 8804). <br />The entire SOP is functioning as designed. There is evidence of sedimentation at each dam <br />location, and the vegetation is establishing itself nicely throughout the system. <br />Additional Inspection Details: <br />The mine ID sign at the entrance gate was intact and contained all of the necessary information. <br />A two -track road appears to have been recently developed off the North Road near its <br />intersection with the Lower Moffat Road, causing disturbance to a previously reclaimed area <br />(Photo 8784). <br />A roadside ditch along the West Ridge Road has significantly eroded and formed a large gully <br />above the String of Pearls (SOP) that is nearly 200 yards long and at least four feet deep in <br />
