Preliminary report on methodology for calculating coal resources of the Wyodak-Anderson coal zone, Powder River basin, Wyoming and Montana
Margaret S. Ellis, Gregory L. Gunther, Romeo M. Flores, Gary D. Stricker, Allan M. Ochs, John H. Schuenemeyer
1998, Open-File Report 98-789-B
The National Coal Resource Assessment of the Wyodak-Anderson coal zone includes reports on the geology, stratigraphy, quality, and quantity of coal. The calculation of resources is only one aspect of the assessment. Without thorough documentation of the coal resource study and the methods used, the results of our study could be misinterpreted. The...
Use of Microgravity to Assess the Effects of El Nino on Ground-Water Storage in Southern Arizona
John T.C. Parker, Donald R. Pool
1998, Fact Sheet 060-98
The availability of ground water is of extreme importance in areas, such as southern Arizona, where it is the main supply for agricultural, industrial, or domestic purposes. Where ground-water use exceeds recharge, monitoring is critical for managing water supplies. Typically, monitoring has been done by measuring water levels in wells;...
Selenium in Reservoir Sediment from the Republican River Basin
Kyle E. Juracek, Andrew C. Ziegler
1998, Fact Sheet 080-98
Reservoir sediment quality is an important environmental concern because sediment may act as both a sink and a source of water-quality constituents to the overlying water column and biota. Once in the food chain, sediment-derived constituents may pose an even greater concern due to bioaccumulation. An analysis of reservoir bottom...
An illustrated environmental bibliography for Buzzards Bay, Massachusetts
Chris F. Polloni, Bruce W. Tripp, Pamela Truesdale
1998, Open-File Report 98-50
  This presentation is a cooperative effort between the Coalition for Buzzards Bay, Woods Hole Oceanographic Institution and the U.S. Geological Survey. Its original intent was to make available an existing large bibliography of environmental information on Buzzards Bay to participants in the series of symposia sponsored by the Massachusetts Maritime...
Elevation maps of the San Francisco Bay region, California, a digital database
Scott E. Graham, Richard J. Pike
1998, Open-File Report 98-625
PREFACE: Topography, the configuration of the land surface, plays a major role in various natural processes that have helped shape the ten-county San Francisco Bay region and continue to affect its development. Such processes include a dangerous type of landslide, the debris flow (Ellen and others, 1997) as well...
Geology of Palo Alto 30 x 60 minute quadrangle, California: A digital database
Earl E. Brabb, R. W. Graymer, David Lawrence Jones
1998, Open-File Report 98-348
This map database represents the integration of previously published and unpublished maps by several workers (see Sources of Data index map on Sheet 2 and the corresponding table below) and new geologic mapping and field checking by the authors with the previously published geologic map of San Mateo County (Brabb...
Ground-water quality in northern Ada County, lower Boise River basin, Idaho, 1985-96
D. J. Parliman, Joseph M. Spinazola
1998, Fact Sheet 054-98
In October 1992, the U.S. Geological Survey (USGS), in cooperation with the Idaho Division of Environmental Quality, Boise Regional Office (IDEQ-BRO), began a comprehensive study of ground-water quality in the lower Boise River Basin. The study in northern Ada County has been completed, and this report presents selected results of...
U.S. Geological Survey Real-Time River Data Applications
Scott E. Morlock
1998, Fact Sheet 029-98
Real-time river data provided by the USGS originate from streamflow-gaging stations. The USGS operates and maintains a network of more than 7,000 such stations across the nation (Mason and Wieger, 1995). These gaging stations, used to produce records of stage and streamflow data, are operated in cooperation with local, state,...
Changes to Idaho's statewide surface-water quality monitoring program since 1995
Ivalou O’Dell, Terry R. Maret, Susan E. Moore
1998, Fact Sheet 137-98
In 1990, the U.S. Geological Survey (USGS), in cooperation with the Idaho Division of Environmental Quality (formerly Idaho Department of Health and Welfare, Division of Environmental Quality), implemented a statewide water- quality monitoring program in response to Idaho’s antidegradation policy as required by the Clean Water Act (CWA). The objective...
Upper Illinois River basin
Michael J. Friedel
1998, Fact Sheet 072-98
During the past 25 years, industry and government made large financial investments that resulted in better water quality across the Nation; however, many water-quality concerns remain. Following a 1986 pilot project, the U.S. Geological Survey began implementation of the National Water-Quality Assessment (NAWQA) Program in 1991. This program differs from...
Geology, geochemistry, geophysics, mineral occurrences, and mineral resource assessment for the Commonwealth of Puerto Rico
Walter J. Bawiec, editor(s)
1998, Open-File Report 98-38
The Commonwealth of Puerto Rico has been investigated over a very long period of time by earth scientists from many disciplines and with diverse objectives in the studies. This publication attempts to apply much of the geologic, geochemical, geophysical, and mineral occurrence information to a single objective focused on producing...
Surface-water/ground-water relations in the Lemhi River Basin, east-central Idaho
Mary M. Donato
1998, Water-Resources Investigations Report 98-4185
This report summarizes work carried out in cooperation with the Bureau of Reclamation to provide hydrologic information to help Federal, State, and local agencies meet the goals of the Lemhi River Model Watershed Project. The primary goal of the project is to maintain, enhance, and restore anadromous and resident fish...
Computer programs for describing the recession of ground-water discharge and for estimating mean ground-water recharge and discharge from streamflow records-update
A. T. Rutledge
1998, Water-Resources Investigations Report 98-4148
The computer programs included in this report can be used to develop a mathematical expression for recession of ground-water discharge and estimate mean ground-water recharge and discharge. The programs are intended for analysis of the daily streamflow record of a basin where one can reasonably assume that all, or nearly...
Quantification of deep percolation from two flood-irrigated alfalfa fields, Roswell Basin, New Mexico
D. Michael Roark, D. F. Healy
1998, Water-Resources Investigations Report 98-4096
For many years water management in the Roswell ground-water basin (Roswell Basin) and other declared basins in New Mexico has been the responsibility of the State of New Mexico. One of the water management issues requiring better quantification is the amount of deep percolation from applied irrigation water. Two adjacent...
