April 28, 2015 C- 1994- 082/Yoast Mine JHB <br />Annand draw was flowing well at Culvert YB -6. Some bank cutting of the road way overlying YB -6 has <br />occurred. This cutting is limited and is not impacting the function of the culvert. SCC needs to monitor this <br />spot and repair if the downcutting increases. <br />YPM -10 and YPM -9 are holding up well. Fall 2014 repairs to YPM -9 near Pond 11A are holding well. Pond 11A <br />was holding water but not discharging. <br />The drainage between Pond I IA and Pond 11 was walked. No new downcutting had occur ed, and the drainage <br />appeared stable. <br />Pond 11 was holding water but well below the discharge elevation. Vegetation on the pond outslope was stable <br />and not eroding. No problems were noted with Pond 11. <br />ST -9 was holding a very small puddle. Most of the runoff runs through this surge tank to YPM -8. Runoff was <br />flowing through ST -9 into YPM -8. The road crossing at YPM -8 and the repairs to the rock lined channel are <br />holding p well. ST -9 embankment had good vegetative cover. Noxious weeds were not observed to be <br />troublesome at the ST -9 site. <br />At the top (northern extent) of YPM -7, a gully is beginning to form. It appears to be a result of winter <br />snowmelt. No apparent water source remained at the time of the inspection, and there was no runoff flowing in <br />the gully or drainage when it was observed. GPS data was collected and will be sent separately to the operator. <br />The gully consisted of 2 branches. The first was approximately 12 feet long and —1 to 1.5 feet deep. The second <br />branch was longer at —20 feet long and was cut down to approximately 2 feet deep. The gully stopped at drainage <br />YPM -7 and surge tank is immediately downslope. Brush packing may be an appropriate stabilization for this <br />gully. SCC needs to manage this gully from continued downcutting. This surge tank was mostly dry and was <br />holding a small puddle of water. <br />YPM -7 was in good condition below the surge tank. <br />Pond 12A was holding water but was not discharging. No problems were noted with pond 12A. <br />Stock tank 1 (ST -1) was holding water, though water elevation was below the dischage elevation. No problems <br />were observed with ST -1. <br />YPM -1 -1 was in good condition with no undercutting of the rock gabions or side cutting of the rip rapped channel. <br />Pond 14 was holding a clear pool of water but was not discharging. Vegetative cover on the Pond 14 embankment <br />was good. <br />Pond 13 was discharging. Discharge from Pond 13 measured —0.10 on the staff gauge on the flume. <br />Number of Partial Inspection this Fiscal Year: 7 <br />Number of Complete Inspections this Fiscal Year: 3 <br />Page 3 of 7 <br />
