Evaluation of selected methods for determining streamflow during periods of ice effect Evaluation of selected methods for determining streamflow during periods of ice effect
Seventeen methods for estimating ice-affected streamflow are evaluated for potential use with the U.S. Geological Survey streamflow-gaging station network. The methods evaluated were identified by written responses from U.S. Geological Survey field offices and by a comprehensive literature search. The methods selected and techniques used for applying the methods are described in this...

Quality-assurance plan for the analysis of fluvial sediment by laboratories of the U.S. Geological Survey Quality-assurance plan for the analysis of fluvial sediment by laboratories of the U.S. Geological Survey
This report describes procedures used by the Iowa District sediment laboratory of the U.S. Geological Survey to assure the quality of sediment-laboratory data. These procedures can be used by other U.S. Geological Survey laboratories regardless of size and type of operation for quality assurance and quality control of specific sediment-laboratory processes. Also described are the...

Hydrologic data for a study of pre-Illinoian glacial till in Linn County, Iowa, water year 1991 Hydrologic data for a study of pre-Illinoian glacial till in Linn County, Iowa, water year 1991
Hydrologic data for a study of pre-lllinoian glacial till were collected during the 1991 water year at a site in Linn County, east-central Iowa. A hydrologic-data-collection network, consisting of a meteorological station, 22 observation wells, and a water-quality minimonitor, was installed at the site to investigate the hydraulic properties of the till. Recorders were installed on 12 of...

Hydrologic data for the Big Spring basin, Clayton County, Iowa, water year 1990 Hydrologic data for the Big Spring basin, Clayton County, Iowa, water year 1990
Hydrologic data were collected in the Big Spring basin located in Clayton County, Iowa, during the 1990 water year. The data were collected by the U.S. Geological Survey in cooperation with the Iowa Department of Natural Resources, Geological Survey Bureau, to provide information on variation and movement of agricultural chemicals in the hydrologic cycle in the basin. Precipitation...

A reconnaissance study of herbicides and their metabolites in surface water of the midwestern united states using immunoassay and gas chromatography/mass spectrometry A reconnaissance study of herbicides and their metabolites in surface water of the midwestern united states using immunoassay and gas chromatography/mass spectrometry
Preemergent herbicides and their metabolites, particularly atrazine, deethylatrazine, and metolachlor, persisted from 1989 to 1990 in the majority of rivers and streams in the midwestern United States. In spring, after the application of herbicides, the concentrations of atrazine, alachlor, and simazine were frequently 3-10 times greater than the U.S. Environmental Protection Agency...

Availability and quality of water from the alluvial, glacial-drift, and Dakota aquifers and water use in southwest Iowa Availability and quality of water from the alluvial, glacial-drift, and Dakota aquifers and water use in southwest Iowa
A ground-water resources investigation was conducted in southwest Iowa to describe the availability, quality, and use of water from the alluvial, glacial-drift, and Dakota aquifers in a nine-county area. Historical water quality was examined for each aquifer, and water samples were collected for major ions, trace metals, radionuclides, and selected pesticides. Selected aspects of surface...

Herbicides in surface waters of the midwestern United States: The effect of spring flush Herbicides in surface waters of the midwestern United States: The effect of spring flush
Approximately three-fourths of all preemergent herbicides used in the United States are applied to row crops over a 12-state area, called the "corn belt" (I). The application of these compounds may cause widespread degradation of water quality (2). Because herbicides are water soluble, there is the potential for leaching into groundwater and surface water (3, 4), as well as aerial...
