Nutrient Loading and Benthic Macroinvertebrate Assessments in Michigan Streams (2002-2021)

The assembled data package, including both nutrients and benthic macroinvertebrate assessments from stream monitoring sites in Michigan (USA), is part of the project entitled "Long-Term Nitrogen and Phosphorus Dynamics and Macroinvertebrate Assemblages in Temperate Streams." These datasets encompass records from January 1, 2002, until December 31, 2021, that were extracted from the Water Quality Portal (www.waterquality.us). We were aiming to examine the influence of landscape settings on the concentration of N and P constituents in streams and rivers, and determine the effects of land use on benthic macroinvertebrates in the interaction with these nutrients over 20 years. Records were cleaned and analyzed to determine the influence of land use settings on nutrient concentrations and benthic macroinvertebrate composition statewide. All data tables feature monitoring sites with sampling dates, identifiers, and GPS coordinates.
