Barbara C Scudder Eikenberry
Barbara Scudder Eikenberry is a Scientist Emerita, previous Hydrologist with the USGS, where she had worked since 1981.
Her expertise is in water quality assessment using freshwater organisms, with emphasis on chemical bioaccumulation and toxicity, also community ecology of algae, invertebrates, and fish. She has a B.A. in Aquatic Biology (1979, University of CA-Santa Barbara) and a M.S. in Marine Science (1984, CA State University, Hayward at Moss Landing Marine Labs). From 1991 to 2012, she was lead biologist for the Western Lake Michigan Drainages study unit of the USGS NAWQA Program. Since 2004, she has led ecological studies for the Milwaukee Corridor Study. She is currently leading benthos and plankton studies in rivermouths and harbors along the Lake Michigan coastline for decision-making input re Beneficial Use Impairments (BUIs) at Great Lakes Areas of Concern.
Focus: Water-quality assessments using stream organisms, with an emphasis on bioaccumulation, toxicity, and community ecology of benthic algae and invertebrates and fish.

Surface-water quality, Oneida Reservation and vicinity, Wisconsin, 1997-98
Streamwater samples were collected at 19 sites in the vicinity of the Oneida Tribe of Indians of Wisconsin Reservation. Samples were collected during 5 sampling periods in 1997-98. Field measurements were made and samples were analyzed for nutrients, suspended sediment, major ions, and pesticides. Physical characteristics and human activity influence surface-water quality in the study area. PredomAuthorsMorgan A. Schmidt, Barbara C. Scudder, Kevin D. RichardsEnvironmental setting of the upper Illinois River basin and implications for water quality
The upper Illinois River Basin (UIRB) is the 10,949 square mile drainage area upstream from Ottawa, Illinois, on the Illinois River. The UIRB is one of 13 studies that began in 1996 as part of the U.S. Geological Survey's National Water-Quality Assessment program. A compilation of environmental data from Federal, State, and local agencies provides a description of the environmental setting of theAuthorsTerri Arnold, Daniel J. Sullivan, Mitchell A.

Sampling was conducted in 1992,1994, and 1995 to determine the occurrence of a broad suite of trace elements and synthetic organic compounds in biota and streambed sediment in selected streams in the Western Lake Michigan Drainages a study unit of the National Water- Quality Assessment (NAWQA) Program of the U.S. Geological Survey.

This study describes the benthic invertebrate communities of 20 benchmark streams in agricultural areas of eastern Wisconsin. Streams with minimal adverse effects from human activity were selected from four agricultural areas with differing surficial deposits and bedrock types (relatively homogeneous units, or RHU's). Most aquatic invertebrate orders were well represented in the 20 benchmark streaAuthorsS. J. Rheaume, B. N. Lenz, B. C.

This report summarizes aquatic biological studies relevant to water-quality assessment that have been done in the Western Lake Michigan Drainages from 1891 to 1996. The objective of the summary was to compile sources of biological data for the U.S. Geological Survey's National Water-Quality Assessment Program. The studies are divided into four categories: (1) populations and community structure ofAuthorsB. C. Scudder, S. J. Rheaume, S.R. Parsons, B. N.

The distribution of 22 major and trace elements was examined in water, sediment, and biota in the upper Illinois River Basin in Illinois, Indiana, and Wisconsin as part of a pilot National Water-Quality Assessment project done by the U.S. Geological Survey from 1987 through 1990.
