The discharge looked clean at the time of the inspection. The l~ond embankment was a bit wet and muddy but was well vegetated and appeared stable at the time of the inspection. No erosional problems were noted in the embankment at the time of the inspection. The area around the pond has been hammered hard by the deer and elk this winter. The emergency spillway is a riprapped open channel. The spillway appeared to be stable at the time of the inspection. -The East Taylor (Pond (NPDES Ol OA) was inaccessible at the time of the inspection due to snow. - The Prospect Pond (NPDES 007A) contained water approximately six feet below the top of the discharge pipe and was discharging through the weep hole on the pipe. The flume was a~vered with snow so no visual water quality was possible. Water was also flowing into the pond (from the melting snow) at the time of the inspection. The pond embankment was covered with snow but it appeared to be well vegetated and stable at thE; time of the inspection. No erosional problems noted on the embankment at the time of the inspection. The emergency spillway is an open, trapezoidal riprapped channel. The spillway appeared to be stable and well maintained at the time of the inspection. The operator (Bower Brothers) has finished cleaning the pored. Two excavators remain to be demobed from the pond. There is some finishing work that needs to be done on the top of the pond embankment and the inslopes of the pond. Tony indicated that this would be completed as the excavators walked out of the area. The final volume of sediment that was removed from the pond was just a bit shy of 8,000 cubic yards.
