Abstract:Sampled macroinvertebrates following ILEPA protocol at nine sites in August and September 2015 in the proposed IL Route 53 and 120 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•Macroinvertebrate Index of Biotic Integrity rated one site as “Good” (Des Plaines River at Rt. 120), seven sites as “Fair,” and one site as “Poor” (Buffalo Cr. at Tall Oaks Dr.)▷ Total taxa richness ranged from 8 to 19 across sites▷ % EPT ranged from 0 to 22.4 across sites▷ No Plecoptera (stoneflies), indicators of good water quality, were collected from any site▷ Ephemeroptera (mayflies) were absent from three of the nine sites
