Report of hydrologic investigations in the Three Sisters area of central Oregon, Summer 2001
William C. Evans, Robert H. Mariner, Steven E. Ingebritsen, B. Mack Kennedy, Matthias C. van Soest, Mark A. Huebner
2002, Water-Resources Investigations Report 2002-4061
An ongoing episode of crustal uplift centered in the Separation Creek drainage of the Three Sisters area, central Oregon Cascades, may result from a magmatic intrusion that began in 1998. An investigation of springs in this drainage in summer 2001 revealed slightly elevated water temperatures and chloride (Cl-) concentrations of...
SUTRA: A model for 2D or 3D saturated-unsaturated, variable-density ground-water flow with solute or energy transport
Clifford I. Voss, A.M. Provost
2002, Water-Resources Investigations Report 2002-4231
SUTRA (Saturated-Unsaturated Transport) is a computer program that simulates fluid movement and the transport of either energy or dissolved substances in a subsurface environment. This upgraded version of SUTRA adds the capability for three-dimensional simulation to the former code (Voss, 1984), which allowed only two-dimensional simulation. The code employs a...

Documented variations in the isotopic compositions of some chemical elements are responsible for expanded uncertainties in the standard atomic weights published by the Commission on Atomic Weights and Isotopic Abundances of the International Union of Pure and Applied Chemistry. This report summarizes reported variations in the isotopic compositions of 20...
A national pilot study of mercury contamination of aquatic ecosystems along multiple gradients" Bioaccumulation in fish
William G. Brumbaugh, David P. Krabbenhoft, Dennis R. Helsel, James G. Wiener, Kathy R. Echols
2001, Biological Science Report 2001-0009
Water, sediment, and fish were sampled in the summer and fall of 1998 at 106 sites from 20 U.S. watershed basins to examine relations of mercury (Hg) and methylmercury (MeHg) in aquatic ecosystems. Bioaccumulation of Hg in fish from these basins was evaluated in relation to species, Hg and MeHg...
California's Yolo Bypass: Evidence that flood control can be compatible with fisheries, wetlands, wildlife, and agriculture
T. Sommer, B. Harrell, M. Nobriga, R. Brown, P.B. Moyle, W. Kimmerer, Laurence E. Schemel
2001, Fisheries (25) 6-16
Unlike conventional flood control systems that frequently isolate rivers from ecologically-essential floodplain habitat, California's Yolo Bypass has been engineered to allow Sacramento Valley floodwaters to inundate a broad floodplain. From a flood control standpoint, the 24,000 ha leveed floodplain has been exceptionally successful based on its ability to convey up...
After site selection and before data analysis: sampling, sorting, and laboratory procedures used in stream benthic macroinvertebrate monitoring programs by USA state agencies
James L. Carter, Vincent H. Resh
2001, Journal of the North American Benthological Society (20) 658-682
A survey of methods used by US state agencies for collecting and processing benthic macroinvertebrate samples from streams was conducted by questionnaire; 90 responses were received and used to describe trends in methods. The responses represented an estimated 13,000-15,000 samples collected and processed per year. Kicknet devices were used in...
Seasonal habitat-use patterns of nekton in a tide-restricted and unrestricted New England salt marsh
K.B. Raposa, C. T. Roman
2001, Wetlands (21) 451-461
Many New England salt marshes remain tide-restricted or are undergoing tidal restoration. Hydrologic manipulation of salt marshes affects marsh biogeochemistry and vegetation patterns, but responses by fishes and decapod crustaceans (nekton) remain unclear, This study examines nekton habitat-use patterns in the tide-restricted Hatches Harbor salt marsh (Provincetown, Massachusetts) relative to...
Nest survival of forest birds in the Mississippi Alluvial Valley
D.J. Twedt, R.R. Wilson, J. L. Henne-Kerr, R.B. Hamilton
2001, Journal of Wildlife Management (65) 450-460
In the Mississippi Alluvial Valley, flood control has led to a drastic reduction in the area of forest habitat and altered the patchwork of forest cover types. Silvicultural management of the remaining fragmented forests has changed to reflect the altered hydrology of the forests, current economic conditions of the area,...
Flow and habitat effects on juvenile fish abundance in natural and altered flow regimes
Mary C. Freeman, Z.H. Bowen, K.D. Bovee, E.R. Irwin
2001, Ecological Applications (11) 179-190
Conserving biological resources native to large river systems increasingly depends on how flow-regulated segments of these rivers are managed. Improving management will require a better understanding of linkages between river biota and temporal variability of flow and instream habitat. However, few studies have quantified responses of native fish...
South Florida Everglades: satellite image map
John Jones, Jean-Claude Thomas, G.B. Desmond
2001, IMAP 2742
These satellite image maps are one product of the USGS Land Characteristics from Remote Sensing project, funded through the USGS Place-Based Studies Program (http://access.usgs.gov/) with support from the Everglades National Park (http://www.nps.gov/ever/). The objective of this project is to develop and apply innovative remote sensing and geographic information system techniques...
Selected hydrologic data for the field demonstration of three permeable reactive barriers near Fry Canyon, Utah, 1996-2000
Chris D. Wilkowske, Ryan C. Rowland, David L. Naftz
2001, Open-File Report 2001-361
Three permeable reactive barriers (PRBs) were installed near Fry Canyon, Utah, in August 1997 to demonstrate the use of PRBs to control the migration of uranium in ground water. Reactive material included (1) bone-char phosphate, (2) zero-valent iron pellets, and (3) amorphous ferric oxyhydroxide coated gravel. An extensive monitoring network...
Potentiometric surface of the Ozark aquifer in northern Arkansas, 2001
Tony P. Schrader
2001, Water-Resources Investigations Report 2001-4233
The Ozark aquifer in northern Arkansas comprises dolomites, limestones, sandstones, and shales of Late Cambrian to Middle Devonian age, and ranges in thickness from approximately 1,100 feet to more than 4,000 feet. Hydrologically, the aquifer is complex, characterized by disconnected and extensive flow components with large variations in permeability. The potentiometric-surface...

Numerical Simulation of Ground-Water Flow and Assessment of the Effects of Artificial Recharge in the Rialto-Colton Basin, San Bernardino County, California
Linda R. Woolfenden, Kathryn M. Koczot
2001, Water-Resources Investigations Report 2000-4243
The Rialto?Colton Basin, in western San Bernardino County, California, was chosen for storage of imported water because of the good quality of native ground water, the known storage capacity for additional ground-water storage in the basin, and the availability of imported water. To supplement native ground-water resources and offset overdraft...
