Apri122, 2014 C- 1982 - 057 /Seneca 11-W Mine JHB <br />Pond 5 was in good condition. This pond was discharging clear, 0.02 on staff gauge. No problems were noted on <br />the embankment or pond inslopes. Staff gauge is mounted on the inlet side of the flume. <br />Pond 009 was visible from the ridgeline. No obvious problems were observed with Pond 009 at this time. <br />Pond 006 was discharging. Oil booms are disintegrating and appear caught under the trash rack. Water elevation <br />is at the top of the primary riser. Some boom material appears to be falling into the riser pipe. Discharge <br />measured 0.18 -0.20 on the staff gauge of the flume. 006 flume requires cleanout. vegetative material is deposited <br />on the bottom of the flume. (Photo 23) <br />Pond 16 was discharging. Pond appeared to be functioning well. <br />Drainages, <br />The drainage downgradient from stocktank T -20 is downcutting. The knickpoint is outside of the disturbance area <br />approximately 40 ft.west of the rock armoring below T -20. This channel is downcut approx. 3 feet and appears <br />that the knickpoint may continue to migrate up channel. A second knickpoint is downcutting even with <br />Groundwater monitoring well GW- S2W -14W. (Photo 6). <br />Drainage 005 -W1 is holding up well. Transplanted tree species are beginning to bud. (Photo 13) <br />005 -Gulch appears stable. No signs of downcutting or serious rilling was noted in the drainage upslope from T- <br />18. Snow drifts were still present on the south side of this drainage. <br />Drainage 006 -NE4 continues to hold up well at the eastern extent. The inspector walked down 006 -NE4 to just <br />west of the powerline. No concerns with 006 -NE4 were noted. <br />A significant gully is forming in the rose thicket between drainage 006 -NE4 and 006 -NE3. A gully is forming 8 "- <br />1 foot deep extending for approximately 150 feet. This gully has cut through the topsoil and is continuing to <br />downcut into the spoil material. SCC needs to conduct rill & gully repair to retard the progress of this gully. <br />006 -NE2 and 006 -NE3 were holding up well. <br />006 -S 1 had a heavy flow of water but was holding up well. <br />006 -E1 and 006 -E2 were holding up well and were dry. <br />006 -Gulch and PM6 were holding up well. Gabions held up well to the snowmelt. (Photos 24 & 25) None of the <br />gabions had failed and all were functioning well. Some channeling of flow was occurring at the 7th gabion west <br />of HRI. <br />Some side cutting of the drainage was occurring at the confluence of 006 -Gulch with 006 -E <br />Drainage between gabion 5 & 6 (west of HRI) has ripped reinforcement fabric and is undercutting. This segment <br />needs maintenance to assure this side drainage does not continue to undercut.
