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...

Ground-water level data for North Carolina, 1988-90 Ground-water level data for North Carolina, 1988-90

Continuous and periodic water-level measurements were made in 59 key wells throughout North Carolina. Additional measurements were made in 112 supplementary wells completed in Coastal Plain aquifers of the State. Changes in groundwater storage are shown in 3-year and 10-year hydrographs of selected wells in the State. The water table in the shallow aquifers was higher throughout most of...

Effects of horizontal velocity variations on ultrasonic velocity measurements in open channels Effects of horizontal velocity variations on ultrasonic velocity measurements in open channels

Use of an ultrasonic velocity meter to determine discharge in open channels involves measuring the velocity in a line between transducers in the stream and relating that velocity to the average velocity in the stream. The standard method of calculating average velocity in the channel assumes that the velocity profile in the channel can be represented by the one-dimensional von Karman...

A summary of water-resources activities of the U.S. Geological Survey in Iowa, fiscal year 1992 A summary of water-resources activities of the U.S. Geological Survey in Iowa, fiscal year 1992

Water-resources activities of the U.S. Geological Survey in Iowa consist of collecting hydrologic data and conducting interpretive studies. Hydrologic investigations in Iowa are made through three basic types of projects: (1) hydrologic data-collection programs; (2) local or areal studies; and (3) statewide or regional investigations. These projects are funded through cooperative joint...

Communications: Blood chemistry of laboratory-reared Golden trout Communications: Blood chemistry of laboratory-reared Golden trout

Golden trout Oncorhynchus aguabonita obtained from a wild stock as fertilized eggs were reared in the laboratory for 21 months. The laboratory-reared golden trout in our study reached sexual maturity earlier and grew more rapidly than wild golden trout do (according to the scientific literature). Male fish averaged 35.6 cm in total length and 426 g in weight, and females averaged 36.2 cm...

Toxicity of trace element and salinity mixtures to striped bass (Morone saxatilis) and Daphnia magna Toxicity of trace element and salinity mixtures to striped bass (Morone saxatilis) and Daphnia magna

Acute toxicity tests with reconstituted water were conducted to investigate the relationship between water hardness, salinity, and a mixture of trace elements found in irrigation drain waters entering Stillwater Wildlife Management Area (SWMA), near Fallon, Nevada. The SWMA has been the site of many fish kills in recent years, and previous toxicity studies indicated that one drain water...
