Minnesota River Assessment Project (MRAP): Biological and Toxicological Assessment - Analysis of Benthic Macroinvertebrate Communities in the Minnesota River Watershed



Minor watershed number(s):   25022, 25147, 25161, 27051, 28033, 28045, 28046, 28066, 30023, 30024, 30030, 30047, 30049, 30050, 30056, 31015, 31047, 31058, 32042, 32067, 32073, 33070, 33075

This study is performed on the following minor watersheds: 25022, 25147, 25161, 27051, 28033, 28045, 28046, 28066, 30023, 30024, 30030, 30047, 30049, 30050, 30056, 31015, 31047, 31058, 32042, 32067, 32073, 33070, 33075. Analysis of additional sites occurred along the main stem and tributaries of the Minnesota River.

The Biological and Toxicological Assessment component of the Minnesota River Assessment Project (MRAP) includes studies which assist in defining existing conditions in the Minnesota River and it's tributaries. This analysis of benthic macroinvertabrate communities is completed as a part of the Biological and Toxicological Assessment component of the Minnesota River Assessment Project (MRAP). The study assesses the status of benthic macroinvertebrate communities within the Minnesota River Basin. These communities serve as effective monitors of environmental conditions and are useful in the assessment of stream quality. The channels sampled ranged widely in size and riparian and instream characteristics over the 41 selected assessment sites. Using the Qualitative Habitat Evaluation Index (QHEI) of the Ohio EPA (1987), physical habitat characteristics at each of the 41 sites was determined. Sampling was performed each summer from 1989-1992.

Biological Monitoring

Data Summary MRAP Biological and Toxicological Assessment - Analysis of Benthic Macroinvertebrate Communities in the Minnesota River Watershed includes data from the collection of qualitative and quantitative macroinvertebrate samples at 41 assessment sites within the Minnesota River main stem, tributaries, and selected minor watersheds. Macroinvertebrate communities data was used to calculate the following metrics: Species Richness, Diversity Index, Equitability Index, Macroinvertebrate Biotic Index (MBI), and Invertebrate Community Index (ICI).
