6. Diversities and equitabilities of benthic samples from <br /> the Crystal River indicate excellent water quality. <br /> 7. Of the sixty-six trout shocked from the Crystal River <br /> 91% were stocked rainbow trout. Except for stations CR-2, CR-3, <br /> and CR-9 the rest of the shocking locations were virtually void <br /> of any naturally occurring trout. <br /> 8. There exists a sufficient difference in sulfate and <br /> solids concentrations below the North Thompson Creek Mines as <br /> compared to above the mines. A healthy trout population existed <br /> in North Thompson Creek above the mines, while only stock fish <br /> were recovered below the mines. <br /> 9. Coal Creek, Bear Creek, and Dutch Creek exhibited very <br /> poor water quality with high solids, sulfate and heavy metals <br /> concentrations due to the Mid-Continent Resources Coal Mines. <br /> Porcupine Creek, a tributary to Coal Creek, was unaffected by <br /> the mining activities and had much better water quality than <br /> Coal Creek or the other tributaries sampled. Limited populations <br /> of aquatic insects in Coal Creek emphasize the degraded quality <br /> of the stream. <br /> 10. According to the insitu fish assay Coal Creek can <br /> support a fish population at those locations tested. <br /> Recommendations <br /> 1 . A bioassay should be run to pin-point problems associated <br /> with the North Thompson Creek Mines on aquatic life. <br /> 2 - <br /> I <br />
