Intermittently, during 1981–2012, the U.S. Geological Survey sampled sites in the White River and several tributaries in the Indianapolis metropolitan area of Indiana for benthic invertebrates and fish communities. During 1981–87, one study focused on benthic-invertebrate data collection at three sites along the White River. During 1994–96, 21 sites were sampled for benthic invertebrates; after 1999, up to 13 sites were sampled for benthic invertebrates and fish communities. The information collected during these studies was used in conjunction with the Indianapolis Department of Public Works and CWA Authority, Inc., programs to help improve overall health of the White River and its tributaries by reducing combined sewer overflows and other point and non-point sources of pollution in the Indianapolis area.

Beginning in 1994, the Ephemeroptera, Plecoptera, and Trichoptera (EPT) Index and Hilsenhoff Biotic Index (HBI) were calculated. Beginning in 1999, the Invertebrate Community Index (ICI) also was calculated from the benthic-invertebrate data. Fish-community data were collected periodically from 1999 to 2012, from which an Index of Biotic Integrity (IBI) was calculated.
