Quality of nutrient data from streams and ground water sampled during water years 1992-2001
David K. Mueller, Cindy J. Titus
2005, Scientific Investigations Report 2005-5106
Proper interpretation of water-quality data requires consideration of the effects that bias and variability might have on measured constituent concentrations. In this report, methods are described to estimate the bias due to contamination of samples in the field or laboratory and the variability due to sample collection, processing, shipment, and...
Effects of prescribed fire in the coastal prairies of Texas
James B. Grace, Larry K. Allain, Heather Q. Baldwin, Arlene G. Billock, William R. Eddleman, Aaron M. Given, Clint W. Jeske, Rebecca Moss
2005, Open-File Report 2005-1287
Prescribed fire is widely applied for habitat management in coastal ecosystems. Fire management plans typically list a variety of objectives for prescribed burning, including succession management, promotion of native flora and fauna, providing habitat for species of importance, wildfire risk reduction (fuels management), as well as reduction and/or prevention of...
Questa baseline and pre-mining ground-water quality investigation. 12. Geochemical and reactive-transport modeling based on tracer injection-synoptic sampling studies for the Red River, New Mexico, 2001-2002
James W. Ball, Robert L. Runkel, D. Kirk Nordstrom
2005, Scientific Investigations Report 2005-5149
Reactive-transport processes in the Red River, downstream from the town of Red River in north-central New Mexico, were simulated using the OTEQ reactive-transport model. The simulations were calibrated using physical and chemical data from synoptic studies conducted during low-flow conditions in August 2001 and during March/April 2002. Discharge over the 20-km reach...
Trends in surface-water quality at selected National Stream Quality Accounting Network (NASQAN) stations, in Michigan
Atiq U. Syed, Lisa R. Fogarty
2005, Scientific Investigations Report 2005-5158
To demonstrate the value of long-term, water-quality monitoring, the Michigan Department of Environmental Quality (MDEQ), in cooperation with the U.S. Geological Survey (USGS), initiated a study to evaluate potential trends in water-quality constituents for selected National Stream Quality Accounting Network (NASQAN) stations in Michigan. The goal of this study is...
Water-chemistry data for selected springs, geysers, and streams in Yellowstone National Park Wyoming, 2001-2002
R. Blaine McCleskey, James W. Ball, D. Kirk Nordstrom, JoAnn M. Holloway, Howard E. Taylor
2005, Open-File Report 2004-1316
Water analyses are reported for one-hundred-twenty-one samples collected from hot springs and their overflow drainages, the Gibbon River, and one ambient-temperature acid stream in Yellowstone National Park (YNP) during 2001-2002. Twenty-five analyses are reported for samples collected during May 2001, fifty analyses are reported for samples collected during September 2001,...
Changes in ground-water levels in the Carlin Trend area, north-central Nevada, 1989-2003
Russell W. Plume
2005, Scientific Investigations Report 2005-5075
Ground-water pumpage in support of gold mining activities, including mine dewatering, has resulted in water-level declines and rises in different parts of the Carlin Trend area in north-central Nevada. Total annual pumpage at the Gold Quarry, Carlin, Genesis, and Betze Mines has ranged from about 5,000 acre-feet in 1989 to...
The orphan tsunami of 1700—Japanese clues to a parent earthquake in North America
Brian F. Atwater, Satoko Musumi-Rokkaku, Kenji Satake, Yoshinobu Tsuji, Kazue Ueda, David K. Yamaguchi
2005, Professional Paper 1707
Summary A puzzling tsunami entered Japanese history in January 1700. Samurai, merchants, and villagers wrote of minor flooding and damage. Some noted that no parent earthquake had been felt; they were wondering what had set off the waves. They had no way knowing that the tsunami had been spawned during an...
Mining Claim Activity on Federal Land for the Period 1976 through 2003
J. Douglas Causey
2005, Data Series 124
Previous reports on mining claim records provided information and statistics (number of claims) using data from the U.S. Bureau of Land Management's (BLM) Mining Claim Recordation System. Since that time, BLM converted their mining claim data to the Legacy Repost 2000 system (LR2000). This report describes a process to extract...
Potentiometric surface map of the Magothy aquifer in southern Maryland, September, 2003
Stephen E. Curtin, David C. Andreasen, Judith C. Wheeler
2005, Open-File Report 2005-1006
This report presents a map showing the potentiometric surface of the Magothy aquifer in the Magothy Formation of Upper Cretaceous age in Southern Maryland during September 2002. The map is based on water-level measurements in 79 wells. The highest measured water level was 83 feet above sea level near the...
Hydrogeology and ground-water availability in the carbonate aquifer system of Frederick County, Virginia
George E. Harlow Jr., Randall C. Orndorff, David L. Nelms, David J. Weary, Roger M. Moberg
2005, Scientific Investigations Report 2005-5161
The carbonate aquifer system of the northern Shenandoah Valley provides an important water supply to local communities, including Frederick County, Va., which depends on ground water as a source of water supply. The county and surrounding area are undergoing increased urbanization, and increased demands on the carbonate aquifer system are...
Ground-water modeling of pumping effects near regional ground-water divides and river/aquifer systems - Results and implications of numerical experiments
Rodney A. Sheets, Denise H. Dumouchelle, Daniel T. Feinstein
2005, Scientific Investigations Report 2005-5141
Agreements between United States governors and Canadian territorial premiers establish water-management principles and a framework for protecting Great Lakes waters, including ground water, from diversion and consumptive uses. The issue of ground-water diversions out of the Great Lakes Basin by large-scale pumping near the divides has been raised. Two scenario...
Changes in streamflow patterns related to hydrologic restoration of a sedge fen wetland in Seney National Wildlife Refuge, Michigan, 1998-2004
B.P. Neff, T. L. Weaver, D.G. Wydra
2005, Scientific Investigations Report 2005-5137
Vast expanses of sedge fen in Schoolcraft County in Michigan's Upper Peninsula were ditched and diked in the early to mid-1900s to promote agricultural development and create waterfowl habitat. Unintended consequences of these actions were far reaching and included the deposition of large amounts of sand in the Manistique River....
Effects of nonpoint and selected point contaminant sources on stream-water quality and relation to land use in Johnson County, northeastern Kansas, October 2002 through June 2004
Casey J. Lee, D.P. Mau, T. J. Rasmussen
2005, Scientific Investigations Report 2005-5144
Water and sediment samples were collected by the U.S. Geological Survey in 12 watersheds in Johnson County, northeastern Kansas, to determine the effects of nonpoint and selected point contaminant sources on stream-water quality and their relation to varying land use. The streams studied were located in urban areas of the...
