All ponds inspected,with the exception of the Fish Creek Borehole Pond, 18LT Pond,Pond C,Pond F and the 6MN pond were discharging at the time of the inspection. All pond embankments were stable with no problems noted with the exception of the following: -The Fish Creek Tipple pond embankment may need to be reseeded in the area of the repair work to the primary spillway. -The 18LT upper pond embankment showed evidence of light erosion that should be addressed to ensure stability. -One large gully was observed on the embankment of the 6MN construction pond with a small amount of sediment observed into the pond. This erosion will need to be addressed. All spillways were functioning as designed with no problems noted. Ditches and Culverts The 18RT Borehole access road drainage ditch#2 was filled in with sediment towards the northern section of the ditch. The ditch will need cleaning to ensure functioning as designed. The 18"CMP Culvert#6 at the northern-most end of the road drainage ditch#2 was—1/2 full of sediment at the inlet,this needs to be cleared to ensure functionality. The collection ditch on the east side of the railway between the batch weigh loadout and the 24"culvert under the railway needs to be reestablished with proper sediment control in place at the culvert.
