Median biotic index scoresǂ for macroinvertebrate and fish assemblages stratified by location and year. Upper watershed tributaries comprise the catchment upstream from Greenville Creek, lower watershed tributaries include all other waters exclusive of the Stillwater River mainstem and Greenville Creek. Dark shaded cells show highly significant (p<0.01) differences between years, light shaded cells show marginally significant differences (p >0.01<0.05) ..................................................................................................................................................
