<br />Mr. Karl Koehler - 2 - <br />May 14 , 1991 <br />It is interesting to note that the data from well MW-1, located in the <br />floodplain and terraces mapping unit compare quite closely with the data from <br />wells MW-2 and MW-3. All wells intercept first "sandy silt and silty sand, <br />some gravel and bout der s" and then "gravel and sil ty sand, sore boul ders". <br />Ground water levels on September 21, 1982 were eight feet below the surface in <br />MW-1, seven feet be]ow the surface in MW-2, and approximately four feet below <br />the surface in MW-3. Permeability in all wells were approximately equal. <br />These data further support the Division's contention that the Geo-Hydro <br />identified "upland areas" in question are indeed part of the flood plain and <br />terrace complex of the North Fork of the Gunnison River. <br />COVCC should produce evidence that would clarify the above discrepancies in <br />the Geo-Fydro studies. Until this is done, the Division cannot change the <br />present AVF designation of this area. <br />We look forward to your reply. If you have any questions or wish to discuss <br />this matter further, please contact me. <br />Sincerel <br />,~-- <br />,^ <br />r~l " Moun t <br />Reclamation Specialist <br />CBM/ ern <br />5562E <br />
