The following data shows the latest calculated annual sediment delivery and existing <br /> capacity. <br /> <br /> Sediment Survey Results <br /> Pond Tear Surveyed Caoaci[v (ac-ft) Avg.

At years <br />end, none of the above-mentioned ponds were 100 percent complete or design considerations <br />had not been completely verified. Therefore, no as-built certifications are inlcuded with <br />this annual report. <br />Peabody has also initialed an in~house program [o determine which ponds are functioning as <br />des i9ned, or functioning as anticipated. Review of the data collected by the hydrologists <br />and field inspections will help determine which (if any) stock tanks should be eliminated <br />from the system. Ponds which are completed in 1994 will be certified and the as-builts <br />will be submitted in the next annual reclamation report. <br />• <br />14 <br />
