SCC cecommends the ne r.c sediment surveys be conducted in 2000 for all four sedimentation <br />• ponds and a complete evaluation can then be conducted. <br />SCC is required by Permit C-00-005, Volume 12, Tab 13, Appe nd ir. 13-9 (from TR-21) to <br />provide as-built drawings for all temporary stock tanks that were constructed in the <br />previous year. No new stock to nla were construe [ed during the 1999. <br />Wildlife Monitoring <br />During Aprrl 1595, a Columbian Sharp-tailed Grouse lek was discovered on the reclaimed land <br />at Seneca II Mine, (lek N11. Powder River Eagle B[udies, a wildlife consulting group, <br />studied [he lek for nine days. Between a and 12 males regularly attended and displayed at <br />[he site in 1995. Again in 1999, Powder River eagle Studies monitored the site. The highest <br />count per day for 1559 observations was 16 males and 2 females on lek pl. During May of <br />1998, another lek (1e4: N2) was discoveced in the wadge pasture. A high count of 14 males <br />and 2 females were observed a[ lek p2 durrny April 1999. In addition to these two leks, a <br />third active site was located during 1998 and 1999 Eield observations. This site is <br />between lek ql and leV: q2. A few male sharp-tailed grouse were displaying at this location <br />• in both 1598 and 1999. Since no females were observed at this third location, we hesitate <br />[o call it a leY. a[ this point. The additional lek and many sightings indicate that the <br />sharp-tailed grouse population using [he Seneca II reclamation is increasing.
