Groundwater <br /> Table 6 shows the results of groundwater sampling during 1989; as <br /> well as a comparison to the baseline year 1986. As can be <br /> expected for such a dry year, water levels were lower than the <br /> relatively wet year of 1986. As has been normal for the preceding <br /> years the quality of groundwater has been highly variable. <br /> Probable Hydrologic Consequences <br /> The McClane Canyon Mine seems to be dewatering a local perched <br /> aquifer whose extent is not known. This aquifer- has little if any <br /> direct communication with the alluvial sediments near McClane <br /> Canyon. Salt Creek will use some of the water generated at the <br /> mine but compared to the total available water in the East Salt <br /> Creek regime the effect will be insignificant . Salt Creek will <br /> probably be importing water for surface dust suppression which <br /> will add to the total water in the East Salt Creek regime . <br /> Additionally, since there are no known water rights adjudicated <br /> for this aquifer , there is little chance that water- interests are <br /> being injured. <br /> If there are questions or if I can be of further assistance please <br /> contact me. <br /> Sincerely, <br /> John M. Walters <br /> Manager of Mine Services <br />
