Conclusions Gilbert Creek Data shows improvement in spawning habitat and invertebrate diversity in restored areas E.coli and Coliform levels being introduced to the creek are high. This is detrimental to the success of this trout stream. Conclusions Elk creek Invertebrate diversity represents water quality and aquatic habitat quality. N (Site J-most downstream) and P issues of concern E.coli and Coliform levels are exceedingly high.
