This pond is well vegetated and no problems were <br /> identified. <br /> Gulch A pond is still mostly iced over and the embankment is still covered with considerable amounts of snow. <br /> The gate is closed and the primary riser is clear of sediment and debris. water/ice level in the pond is <br /> approximately 4-5 feet below the primary riser discharge elevation. Several small animal burrows were observed <br /> on the inslope north of the riser. These holes need to be filled in. <br /> Prospect pond was discharging slightly cloudy, 0.02 on the flume. Chip cleared the flume of sediment during the <br /> inspection. The flume does not appear to be level as flow was higher on the east side of the flume than the west. <br /> The Prospect pond remains partially ice covered. The gate is closed and the weep holes inthe riser pipe were <br /> functioning properly. No problems were identified with the embankment. <br /> ROADS—Rule 4.03 <br /> Construction 4.03.1(3)/4.03.2(3) <br /> Drainage 4.03.1(4)/4.03.2(4) <br /> Surfacing and Maintenance4.03.1(5)and(6)/4.03.2(5)and(6) <br /> Reclamation 4.03.1(7)/4.03.2(7): <br /> The haul roads throughout the mine were thawing and as a result some portions were very muddy. <br /> Colowyo had done a good job of keeping the active haulroads well graded and drained. Lesser used roads were <br /> muddy and some areas had ponded water where snow drifts had recently melted. Repair work was being <br /> conducted to berms along the haul road. <br /> REVEGETATION—Rule 4.15 <br /> Vegetative Cover; Timing: <br /> Colowyo contunies to seed 2010 reclamation areas that had not been seeded in the fall. These areas are in <br /> the west pit reclamation area as well as some in the East pit.. The operator is using broadcast methods as weather <br /> conditions allow. Colowyo plans to continue to seed approximately 5 acres in the west pit reclamation on 3/17, <br /> weather permitting. <br /> Grasses are just beginning to show spring emergence in the established reclaimed areas of the east pit. <br /> SUPPORT FACILITIES - Rule 4.04: <br /> Facilities area is well graded and draining to minimize muddy areas. Ditches around the facilities area <br /> will need to be reshaped this spring as the snow/ice piles melt off.
