Scudder Eikenberry, B.C., Nott, M.A., Stewart, J.S., Sullivan, D.J., Fitzpatrick, F.A., Bell, A.H., and Olds, H.T., 2020, Aquatic community and environmental data for 14 rivers and streams in the Milwaukee Metropolitan Sewerage District Planning Area, 2004-13: U.S. Geological Survey data release,


In 2004, 2007, 2010, and 2013, the U.S. Geological Survey sampled benthic algae and invertebrates, and fish to assess the condition of the aquatic communities and water quality in 14 wadable streams near Milwaukee, Wisconsin. Additional community sampling was also done at a subset of three sites in 2011 and 2012 to assess temporal variation. Selected environmental (physical and chemical) data in the streams were collected to evaluate potential relations to the biota and the ecological health of the streams. Physical and chemical data included land-use/land cover; streamflow from USGS gages (except at two creeks that were not gaged); stream habitat; microhabitat at invertebrate collection points (depth, velocity, dominant substrate, [...]

The study is a cooperative effort between the Milwaukee Metropolitan Sewerage District (MMSD) and the Upper Midwest Science Center of the U.S. Geological Survey (USGS). The overall goal of this long-term study is to improve the understanding of water resources in the MMSD planning area by evaluating the quality of aquatic biological communities of in stream corridors and by providing information for assessing the potential success of current and future management efforts. The specific objectives of the study are to assess the integrity of aquatic communities at MMSD sites and evaluate relations to potential environmental stressors including land use, streamflow, habitat, and water chemistry. Data collection was part of a larger water-quality study that began in 2000 to assess the water quality of selected stream sites in the Milwaukee area for the MMSD.
