Water-Quality Stations
PERIOD OF PROJECT: Continuous since 1906
PROJECT CHIEF: Greg Nalley (gmnalley@usgs.gov)
STUDY AREA: Statewide
COOPERATING AGENCIES: U. S. Geological Survey (Federal program)
NEED FOR STUDY: Water-resource planning and water-quality assessment
require a nationwide data base with standardized information for planning and
assessment of water resources. Furthermore, the chemical and physical quality of
the rivers and streams need to be monitored and defined to effectively manage
the resource.
OBJECTIVES: To provide a national data base for water-quality
information for Federal planning and action programs and to provide data for
Federal management of interstate waters.
PROGRESS: Water-quality data were collected and compiled for inclusion
in the Annual Data Reports. Peak flowdischarge measurements and water quality sample were
collected by the USGS Iowa district personnel during the Mississippi River flood of April,
2001.
Measurements of specific conductance and water temperature are taken
at all surface-water gaging stations when streamflow measurements are made. These
miscellaneous water-quality measurements are also published in the Annual
Report.
