POWDERHORN <br />COAL COMP,4NY <br />March 2, 1988 <br />Thomas D. Gillis <br />Colorado Mined Land Reclamation Division <br />1313 Sherman Street, Room 423 <br />Denver, Colorado 80203-2273 <br />Re: 1987 Annual Hydrologic Report, File C-81-041 <br />Dear Tom: <br />Enclosed please find a copy of our 1987 Annual Hydrologic Report which includes <br />the 1987 mine inflows study and map. This submission is designed to be included <br />in the three-ring binder submitted with the 1986 Annual Hydrologic Report. <br />The report should be inserted following the 1987 tab, the inflows map should <br />-• be placed in the map pocket following the 1987 tab and the data pages should <br />replace the same pages in the data section. Also included is a replacement <br />page for Table C86-1 in the 1986 Annual Hydrologic Report. Errors were found <br />on this Table when copying information for the 1987 Annual Hydrologic Report. <br />The errors did not affect the totals. <br />Contrary to our recent phone discussion, this report covers the entire 1987 <br />water year rather than the first nine months of 1987. The information from <br />the last quarter of the 1986 Annual Hydrologic Report is repeated in this <br />report. <br />Three of the four comments in the memo from Steve Renner to you on August 6, <br />1987 concerning our 1986 Annual Hydrologic Report were addressed in this <br />Annual Hydrologic Report. As requested, the reporting was changed to a water <br />year reporting period. Comments 2 and 3 were partially covered by including <br />information on the Colorado River at the USGS Cameo Station 955. No attempt <br />was made to subtract out the affect of lower Plateau Creek. <br />If there are any questions concerning this report, please let me know. <br />Sincerely, <br />LarAry M.
