Abstract:Sampled macroinvertebrates following ILEPA protocol at 4 sites in September 2015 in the I-90 corridor and calculated biotic integrity metrics•Assessed sites based on the Qualitative Stream Habitat Assessment Procedure (SHAP)•Measured physical (width, depth, velocity) and chemical (pH, conductivity, salinity, total dissolved solids) characteristics•Habitat assessment showed impairment compared to Illinois reference conditions at all sites but ranged from “Poor” to just under “Good”•Macroinvertebrate Index of Biotic Integrity rated 1 site as “Exceptional,” 2 as “Good,” and one as “Fair”▷ Total taxa richness ranged from 18 to 26 across sites▷ Kishwaukee River had an “exceptional” biotic integrity rating
