Scudder Eikenberry, B.C., Olds, H.T., Besser, J.M., and Dorman, R.A., 2020, Bottom sediment chemical data at rivermouths and harbors along western Lake Michigan, USA, 2016: U.S. Geological Survey data release,


Streambed sediment samples were collected in October 2016 from streams tributary to Wisconsin’s western Lake Michigan shoreline. Streams included two Areas of Concern (AOCs), two non-AOC comparisons, and two additional non-AOC study areas. Within the Milwaukee Estuary AOC, samples were collected from the Milwaukee River (three subsites), the Menomonee River (two subsites), the Kinnickinnic River (2 subsites), and the Milwaukee Harbor (one subsite). The Milwaukee, Menomonee, and Kinnickinnic Rivers converge in the Milwaukee Harbor and then discharge to Lake Michigan. Within the Sheboygan River AOC, samples were collected at three subsites. Samples were also collected at two subsites in the Manitowoc River and two subsites in the Root [...]

The goal of the study was to evaluate sediment chemistry and potential sediment toxicity to benthic invertebrates and inform management actions with respect to sediment remediation and habitat restoration.
