The U.S. Geological Survey (USGS) has named Gregory M. Clark as the Associate Director for Hydrologic Investigations for its Idaho Water Science Center, headquartered in Boise.
Clark has served as the center's Associate Director for Hydrologic Data since 2002, overseeing a statewide network of USGS streamgages and groundwater monitoring sites. In his new role, he will direct the center's scientific studies of water resources in Idaho.
After graduating from Southern Illinois University in 1985 with a degree in environmental science, Clark joined the USGS Colorado Water Science Center. He earned a Master of Science degree in hydrology from Colorado State University in 1988. While in Colorado, Clark completed hydrologic and geochemical assessments of reclaimed mine lands, studied the transport of pesticides in water, and characterized the hydrology of upland watersheds.
In 1991 Clark moved to Idaho to be the surface-water specialist for the Upper Snake River study unit of the USGS National Water Quality Assessment (NAWQA) program. He was named chief of the Northern Rockies Intermontane Basin NAWQA study unit in 1998. He has authored 19 USGS reports and refereed journal articles, including publications examining pesticide and nutrient transport in the Mississippi River Basin.
The USGS Idaho Water Science Center provides reliable, impartial scientific information about surface and ground water, water quality, and water use to citizens and to local, state, tribal, and federal cooperators. In addition to the Boise headquarters, the center has field offices in Boise, Post Falls, Twin Falls, and Idaho Falls, as well as a project office at the U.S. Department of Energy's Idaho National Laboratory in Idaho Falls.
