Jeff Frey
Jeff's research focuses on the transport of and biological response to nutrients, primarily in the Midwest. Recently the focus has been on edge-of-field studies and Supergages to better understand transport of nutrients. A focus recently has been building water quality and streamgage networks through collaborations with key groups like the Indiana Water Monitoring Council, Indiana Silver Jackets,
He began working with the USGS after graduate school in Indiana 1992 with the National Water-Quality Assessment (NAWQA) Program and has held several positions since then including overseeing the White River - Miami River NAWQA study unit and coordinating the Midwest Stream Quality Assessment in collaboration with the USEPA and NAWQA in 2013. Currently, he is the Director of the USGS Indiana-Kentucky Water Science Center in Indianapolis.

Use of remote-sensing techniques to survey the physical habitat of large rivers
Remote-sensing techniques that can be used to quantitatively characterize the physical habitat in large rivers in the United States where traditional survey approaches typically used in small- and medium-sized streams and rivers would be ineffective or impossible to apply. The state-of-the-art remote-sensing technologies that we discuss here include side-scan sonar, RoxAnn, acoustic Doppler curreAuthorsThomas A. Edsall, Thomas E. Behrendt, Gary Cholwek, Jeffery W. Frey, Gregory W. Kennedy, Stephen B. SmithWater-quality assessment of the White River Basin, Indiana: Analysis of selected information on nutrients, 1980-92
Water-quality data from 23 surfacewater-quality monitoring sites operated by the Indiana Department of Environmental Management and streamflow data from 11 U.S. Geological Survey streamflow-gaging stations in the White River Basin were analyzed to determine recent (1981 90 water years) water-quality conditions, trends, and river loads for ammonia, nitrate, total nitrogen, and total phosphorus.

Since 1875, researchers have reported 158 species of fish belonging to 25 families in the White River Basin. Of these species, 6 have not been reported since 1900 and 10 have not been reported since 1943. Since the 1820's, fish communities in the White River Basin have been affected by the alteration of stream habitat, overfishing, the introduction of non-native species, agriculture, and urbanizatAuthorsCharles G. Crawford, Michael J. Lydy, Jeffrey W. FreyAssessment of water quality at selected sites in the White River Basin, Indiana, 1993 and 1995 using biological indices
As part of the National Water Quality Assessment (NAWQA) Program, fish communities were sampled at 11 sites in the White River Basin, Indiana, in 1993 and 1995 to help determine water-quality conditions. Ninety-one species of fish with representatives from 18 families were collected in the basin. Total numbers of fish collected at every site increased between collection years.
