EAST FORK BRUSH CREEK <br /> The aquatic macro invertebrate commmunity indicated that there was <br /> good water quality and good instream substrate in the reach sampled. <br /> Cleanwater species included the mayflies ",r with a good resident <br /> population, RUj&h&g,ggiijg, and gggrg;" , one of the most sensitive <br /> of the mayflies, with a good resident population, stoneflieslg�g, <br /> and ggp There were indications of a moderate amount of <br /> nutrients in this ecosystem. Sedimentation did not appear to be a problem. <br /> The number of shredders in the community is generally found where riparian <br /> habitat is in fairly good condition, and the diversity and resident <br /> population numbers for many of the taxa indicated there was good stability <br /> in this ecosystem. <br /> The potential for a resident fishery on this stream appeared to be <br /> fairly good. Cleanwater species present indicated there would be suitable <br /> spawning substrate available, and the macro invertebrate biomass of 1 .0 <br /> g/m2 could provide nutrients for a fairly good fishery but was low for a <br /> stream with 71 mg/l alkalinity. <br /> The BCI value of 96 indicated that this ecosystem was close to its <br /> potential, and a management option might simply be to maintain existing <br /> good conditions in this aquatic ecosystem. This stream also will provide <br /> an excellent basis for evaluation of the effects of establishment and <br /> operation of a ski area within this drainage. <br /> 7 <br />
