IBI Metrics Field Chemistry
Summary: The fish community is mainly comprised of tolerant fish species. There were numerous concrete slabs and areas with asphalt sloughing off into the stream from bordering parking lots. The "marginal" habitat along with high specific conductance and high percent impervious cover in the surrounding watershed have all negatively affected the fish community.
