The Tipple (DMP 001), West Ridge, Center Ridge (DMP 007), and Moffat <br />Ponds (DMP 004) were all inspected and functioning as designed. The annual certifications for <br />these ponds are included with this package. <br />As a result of an early September storm event, several of the West Ridge Check Dams <br />require maintenance prior to certification. Maintenance items were noted with recommendations <br />on the individual inspection reports. The maintenance work is scheduled for completion in <br />October 2003. The West Ridge Check Dams will be certified upon completion of the required <br />maintenance. <br />Please contact me at (307) 742-0031 with any questions or comments you have regarding <br />this matter. <br />SL:sb <br />Enclosures <br />cc: Mr. Steve Leach, w/enclosures <br />File: 99-144 <br /> <br />Project Engineer <br />
