These basic benthic survey data provide the number of each taxon in each replicate sample (abundance), density, and biomass. Similar lake wide surveys were conducted to assess the status of benthic taxa beginning in 1994/1995 and repeated every five years through 2015. The purpose of the survey was to assess the status of the benthic macroinvertebrate community, with a primary focus on the invasive mussels Dreissena polymorpha and Dreissena rostriformis bugensis, and the native amphipod Diporeia. While the surveys in 1994/95 focused only on Dreissena and Diporeia, the survey in 2015 was broader in scope and documented abundances and biomass of all macrobenthic taxa. Thus, the 2015 survey provides a baseline to assess future changes of the entire benthic community in Lake Michigan.

Organisms were sorted, counted, and placed into separate vials by major taxonomic groups. For more detailed information see Nalepa, T. F., D. L. Fanslow, M. B. Lansing, G. A. Lang, M. Ford, G.
