These three indices are based on species richness, trophic composition, diversity, presence of pollution-tolerant individuals or species, abundance of biomass, and the presence of diseased or abnormal organisms. The IBI and the MIWB apply to fish; the ICI applies to macroinvertebrates. </SPAN></P><P><SPAN>attributes that contain index scores and sampling year and project: </SPAN></P><P><SPAN>ALU: Aquatic Life Use Designation</SPAN></P><P><SPAN>FISH_YEAR: Year the fish data was collected</SPAN></P><P><SPAN>IBI_SCORE : Index of Biotic Integrity value</SPAN></P><P><SPAN>MIWB_SCORE : Modified Index of Well-Being</SPAN></P><P><SPAN>BUG_YEAR : year macroinvertebrates were collected</SPAN></P><P><SPAN>ICI_SCORE : Invertebrate Community Index value </SPAN></P><P><SPAN>BUG_NARR_SCORE : </SPAN></P><P><SPAN>QHEI_SCORE: Qualitative Habitat Evaluation Index</SPAN></P><P><SPAN>ATTAINMENT : </SPAN></P><P><SPAN>PROJECT : project name</SPAN></P><P><SPAN /></P><P><SPAN>https://epa.ohio.gov/divisions-and-offices/surface-water/reports-data/water-quality-standards-program</SPAN></P><P><SPAN>https://epa.ohio.gov/divisions-and-offices/surface-water/reports-data/biological-criteria-for-the-protection-of-aquatic-life</SPAN></P></DIV>
