Downdrain #4 into Moffat Pond (2nd drain from North end) has rip rap <br />eroded out in a channel down the center. In one area 60'upstream <br />from pond, the liner fabric is exposed and torn and needs <br />maintenance. Down drain #2 is in good, stable condition. However, <br />there is a gully system developing on the west-facing slope between <br />the reclaimed stretches of the middle and lower haul roads. Another <br />cluster of gullies occurs on the slope 50' south of down drain #4. <br />On the slope above spoils springs 16/17 a large gully (up to 40" <br />deep) follows a contour furrow, then enlarges and cuts downhill <br />across the furrows. (see enforcement actions - NOV C-97-007). <br />Final Moffat Drainage channel is eroded resulting in sediment (from <br />fine size to rocks 8" in diameter) blocking the outfall into the <br />pond. This blockage caused flow to short circuit around the pond, <br />running through the old pump pad area and into Trout Creed. Also, <br />the north diversion ditch is blocked by debris, so disturbed area <br />runoff was also diverted through former Trout Creek Pump Pad, out <br />of reclaimed area into undisturbed area and ultimately into Trout <br />Creek. (see enforcement actions - C-97-007.) <br />Goat Trail: The ditch and road downhill of down drain #4 is stable <br />and functioning. The culvert at the 4th switchback is stable, in <br />good repair and functioning. <br />The drop structure at the 5th switchback shows active erosion in the <br />gully below the structure. It appears that a significant amount of <br />water has been added to the drainage there from the recently <br />reclaimed conveyer corridor. Maintenance is needed on the drop <br />structure. <br />Drop structure #3 is in perfect condition and stable. <br />Large gullies have formed down the face of the Conveyer Corridor <br />reclamation at the site of the Conveyer B-C Transfer. P&M has tried <br />to repair these, but conditions have been too wet and the dozer <br />operators won't work on it until it dries out. <br />The 4th culvert is stable and functioning. <br />The conveyer corridor reclamation shows some erosion on the slope <br />both at switchback #5 and below the 3rd drop structure. <br />Tipple Ponda: Pond #1 is completely full of sediment right up to <br />spillway. P&M is preparing to this dredge pond. (see enforcement <br />actions.) <br />Tipple Pond #2 is overflowing; water is discharging through side of <br />pond and flowing around Pond 3 beside the RR tracks at a rate of <br />about 10 gpm. The water does re-enter the ditch and subsequently <br />
