Gore Creek watershed, Colorado — Assessment of historical and current water quantity, water quality, and aquatic ecology, 1968–98
Kirby H. Wynn, Nancy J. Bauch, Nancy E. Driver
2001, Water-Resources Investigations Report 99-4270
The historical and current (1998) water-quantity, water-quality, and aquatic-ecology conditions in the Gore Creek watershed are described as part of a study by the U.S. Geological Survey, done in cooperation with the Town of Vail, the Eagle River Water and Sanitation District, and the Upper Eagle Regional Water Authority. Interpretation...

2001, Water Data Report OK-00-2
Volumes 1 and 2 of the water resources data for the 2000 water year for Oklahoma consists of record of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes or reservoirs; and water levels of ground-water wells. This report contains discharge records for. 134 gaging...
Evaluation of nonpoint-source contamination, Wisconsin: water year 1999
John F. Walker, D.J. Graczyk, Steven R. Corsi, J.A. Wierl, D.W. Owens
2001, Open-File Report 2001-105
The objective of the watershed-management evaluation monitoring program in Wisconsin is to evaluate the effectiveness of best-management practices (BMPs) for controlling nonpoint-source pollution in rural and urban watersheds. This progress report provides a summary of the data collected by the U.S Geological Survey for the program and a discussion of...
Hawaii Beach Monitoring Program: Profile locations
Ann E. Gibbs, Bruce M. Richmond, Charles H. Fletcher, Kindra P. Hillman
2001, Open-File Report 01-308
Coastal erosion is widespread and locally severe in Hawaii and other low-latitude areas. Typical erosion rates in Hawaii are in the range of 15 to 30 cm/yr (0.5 to 1 ft/yr; Hwang, 1981; Sea Engineering, Inc., 1988; Makai Ocean Engineering, Inc. and Sea Engineering, Inc.,1991). Recent studies on Oahu (Fletcher...
Structural controls on ground-water conditions and estimated aquifer properties near Bill Williams Mountain, Williams, Arizona
Herbert A. Pierce
2001, Water-Resources Investigations Report 2001-4058
As of 1999, surface water collected and stored in reservoirs is the sole source of municipal water for the city of Williams. During 1996 and 1999, reservoirs reached historically low levels. Understanding the ground-water flow system is critical to managing the ground-water resources in this part of the Coconino Plateau....
Influence of natural factors on the quality of midwestern streams and rivers
Stephen D. Porter, Mitchell A. Harris, Stephen J. Kalkhoff
2001, Water-Resources Investigations Report 2000-4288
Streams flowing through cropland in the Midwestern Corn Belt differ considerably in their chemical and ecological characteristics, even though agricultural land use is highly intensive throughout the entire region. These differences likely are attributable to differences in riparian vegetation, soil properties, and hydrology. This conclusion is based on results from...
Use of InSAR to identify land-surface displacements caused by aquifer-system compaction in the Paso Robles area, San Luis Obispo County, California, March to August 1997
David W. Valentine, Jill N. Densmore, Devin L. Galloway, Falk Amelung
2001, Open-File Report 2000-447
The population in San Luis Obispo County has grown steadily during the 1990s, and some land use has been converted from dry farming to grazing to irrigated vineyards and urban areas. Because insufficient surface-water supplies are available to meet the growing demand, ground-water pumpage has increased and the resulting water-level...
Water-Chemistry and On-Site Sulfur-Speciation Data for Selected Springs in Yellowstone National Park, Wyoming, 1996-1998
James W. Ball, D. Kirk Nordstrom, R. Blaine McCleskey, Martin A.A. Schoonen, Yong Xu
2001, Open-File Report 2001-49
Fifty-eight water analyses are reported for samples collected from 19 hot springs and their overflow drainages and one ambient-temperature acid stream in Yellowstone National Park (YNP) during 1996-98. These water samples were collected and analyzed as part of research investigations on microbially mediated sulfur oxidation in stream waters and sulfur redox speciation in...
Water resources data, Washington, water year 2000
R. A. Kimbrough, R. R. Smith, G.P. Ruppert, W.D. Wiggins, S.M. Knowles, V.F. Renslow
2001, Water Data Report WA-00-1
Water resources data for the 2000 water year for Washington consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels of wells....
Digital data for construction material sources reported by the Arizona Department of Transportation in 1977 for Maricopa County, Arizona
Douglas M. Hirschberg, G. Stephen Pitts, Henry L. Melcher, James D. Bliss
2001, Open-File Report 2001-122
Material inventories for prospective sources of material for use in building roads and associated structures were prepared by Arizona for several counties including Maricopa County. The inventories provide information about pit locations, materials classification and type, and measures of some characteristics used to determine suitability for aggregate. The digital data given...

Freshwater flow from estuarine creeks into northeastern Florida Bay
Clinton Hittle, Eduardo Patino, Mark A. Zucker
2001, Water-Resources Investigations Report 2001-4164
Water-level, water-velocity, salinity, and temperature data were collected from selected estuarine creeks to compute freshwater flow into northeastern Florida Bay. Calibrated equations for determining mean velocity from acoustic velocity were obtained by developing velocity relations based on direct acoustic measurements, acoustic line velocity, and water level. Three formulas were necessary...
