Biological metrics used in a USGS National Water Quality Project assessing nutrients in agricultural streams

This dataset includes algal and invertebrate metrics used to assess water quality conditions in agricultural streams of the Midwest. Data was collected in wadable streams from 2003 to 2008. Data includes two benthic algal metrics (percent eutrophic taxa and observed taxa/expected taxa) and two benthic invertebrate metrics (EPT taxa and observed taxa/expected taxa).
