The ponds both appeared to be generally in good condition. The requir <br />storage volume lis adequate at this time based upon the sedimentation gaged <br />pionds (see Pic. 1). In the, event that t�here is above average snowfall a1ccurnJation during t <br />winter months, the ponds may need to have the excess sediment removed after the spri <br />runoff. <br />The drainage ditches and pipes were obscured by snow accumulation but, should be <br />generally good condition. The geofabric for the north sediment trap at the site entrance h <br />been repaired to pre�vent runoff from getting under the fabric and allowing sediment to esca <br />thsite (see Pic. 2). All pipeis, ditches and sediment traps should be inspected and repaired <br />niecessairy, once sufficient snow accumulation has melted. . <br />1 <br />e <br />The drainage fo,r the overaill site should be functioning well alnid generally in good shape. There <br />were no specific items noted during the inspection which required attention due to the snow <br />present onsite atthe time of the inspection. Thie drainage features have been constructed aind <br />appear to be operating as stated in the drainage plan submitted to the Division of Minerals aind <br />Geology. <br />P.C.
