Since 1980, scientists have monitored geologic unrest in Long Valley Caldera and at adjacent Mammoth Mountain, California. After a persistent swarm of earthquakes beneath Mammoth Mountain in 1989, geologists discovered that large volumes of carbon dioxide (CO2 ) gas were seeping from beneath this volcano. This gas is killing trees...

The history of stream gaging in Ohio
Kimberly Shaffer
2000, Fact Sheet 050-00
IntroductionStreams are a natural resource that can influence economic growth and the development of communities. They supply water for many uses, provide habitat for aquatic plants and animals, and sup-port recreational activities such as boat-ing and fishing. The amount of water (flow) in a stream — either too little or...
Borehole-radar methods: Tools for characterization of fractured rock
Kamini Singha, Kari Kimball, John W. Lane Jr.
2000, Fact Sheet 054-00
Locating and characterizing bedrock fractures and lithologic changes is an important component of studies of ground water supply and contamination in fractured-rock aquifers. Borehole-radar reflection methods provide information on the location, orientation, and lateral extent of fracture zones that intersect the borehole, and can identify fractures in the rock surrounding...

The stream segment and stream network temperature models: A self-study course
John M. Bartholow
2000, Open-File Report 99-112
I am pleased to have had the opportunity to revise the first version of this set of course notes for the stream temperature models. In some ways, there have been many changes and in some ways the notes have stayed much the same. Generally, I was satisfied that the notes...
Height changes in the epicentral region preceding the January 17, 1994 Northridge earthquake
Robert O. Castle, Robert F. Packard, Laura B. Dinitz
2000, Open-File Report 2000-2
Analysis of the results of repeated levelings through the epicentral region of the Mw 6.7, 1994 Northridge earthquake has disclosed the occurrence of differential uplift in this area that preceded the earthquake. Although the distribution of the relevant vertical-control data is somewhat sparse, in both space and time, those data...
Geologic datasets for weights of evidence analysis in Northeast Washington: 4. mineral industry activity in Washington, 1985-1997
D. E. Boleneus, R. E. Derkey
2000, Open-File Report 2000-14-B
This report includes a table of 339 sites representing mineral activities for mining and mineral exploration in the State of Washington from 1985 through 1997. The table was primarily compiled from annual reports in Washington Geologic Newsletter and Washington Geology. The information was compiled for use in a weights-of-evidence analysis...

Overview of the Texas Source Water Assessment Project
Randy L. Ulery
2000, Fact Sheet 101-00
The 1996 Amendments to the Safe Drinking Water Act require, for the first time, that each state prepare a source water assessment for all PWS. Previously, Federal regulations focused on sampling and enforcement with emphasis on the quality of delivered water. These Amendments emphasize the importance of protecting the source...

The Devils Lake Basin is a 3,810-square-mile subbasin in the Red River of the North Basin. At an elevation of about 1,447 feet above sea level, Devils Lake begins to spill into Stump Lake; and at an elevation of about 1,459 feet above sea level, the combined lakes begin to...
Ground-water flow and water quality of the Indian Island well field near Grand Island, Nebraska, 1994-95
Patrick J. Emmons, Phillip R. Bowman
2000, Fact Sheet 179-99
Ground water is the principal source of water for public and self-supplied domestic use in Nebraska. Ground water supplied about 235 Mgal/d (million gallons per day) in 1990, or about 78 percent of the estimated public-water supply in Nebraska. In addition, ground water supplied about 1,017 Mgal/d, or about 83...

Robert H. Abrams , Keith Loague
2000, Water Resources Research (36) 2001-2013
This paper, the first of two parts [see Abrams and Loague, this issue], takes the compartmentalized approach for the geochemical evolution of redox zones presented by Abrams et al. [1998] and embeds it within a solute transport framework. In this paper the compartmentalized approach is generalized to facilitate the description of its...
