The data set includes the macroinvertebrate metrics calculated by IDAS software (Cuffney 2003, USGS OFR 03-172) for the Midwest Stream Quality Assessment (MSQA). Invert data is taxonomic data that has been summarized into variables called metrics that summarize various components of the taxonomic data. The original taxonomic data comes from USGS BioData.

The data were collected from 99 streams in 11 different States in the Midwest as part of USGS MSQA project. The data is bioassessment of these streams using the ecological data (macroinvertebrate metrics) as indicators of the stream condition and to relate these data to various environmental stressors (nutrients, contaminants, sediment and flow alteration) to gain better understanding of the causes of impairment.
