The second ditch from the top contained a blowout that is causing a large rill, approximately one foot <br />deep and four feet wide. All other contour ditches in this area (above Moffat Pond) as well as the Moffat Final Pit <br />Segment 2 Ditch were found to be in good condition. <br />Center Ridge Pond, West Ridge Pond, and Moffat Pond were all holding water. Center Ridge was discharging <br />clear water; the flow was small. Other observations: <br />• The primary spillway out of the West Ridge Pond is rusted and contains a sizable hole approximately 10 <br />feet from the downstream end. <br />• The primary spillway at Moffat is rusty, but the rust is only significant at the four feet at the end, which is <br />above ground. <br />For all ponds, no problems were observed with embankments. <br />The Koll ditch was found to be in good condition. <br />Some of the check dams above West Ridge Pond are holding water (at the bottom). The upper check dams are <br />nearly filled in with sediment. No problems were identified. <br />Number of Partial Inspection this Fiscal Year: I <br />Number of Complete Inspections this Fiscal Year: 0 <br />Page 2 of 5 <br />
