Water Resources Data, Kentucky, Water Year 2000
D.L. McClain, F.D. Byrd, A.C. Brown
2001, Water Data Report KY-00-1
Water resources data for the 2000 water year for Kentucky consist of records of stage, discharge, and water quality of streams and lakes; and water levels of wells. This report includes daily discharge records for 114 stream-gaging stations. It also includes water-quality data for eight stations sampled at regular intervals...
Simulated effects of pumping irrigation wells on ground-water levels in western Saginaw County, Michigan
Christopher J. Hoard, David B. Westjohn
2001, Water-Resources Investigations Report 2001-4227
Success of agriculture in many areas of Michigan relies on withdrawal of large quantities of ground water for irrigation. In some areas of the State, water-level declines associated with large ground-water withdrawals may adversely affect nearby residential wells. Residential wells in several areas of Saginaw County, in Michigan's east-central Lower...
Determination of instream metal loads using tracer-injection and synoptic-sampling techniques in Wightman Fork, southwestern Colorado, September 1997
Roderick F. Ortiz, Kenneth E. Bencala
2001, Water-Resources Investigations Report 2000-4154
Spatial determinations of the metal loads in Wightman Fork can be used to identify potential source areas to the stream. In September 1997, a chloride tracer-injection study was done concurrently with synoptic water-quality sampling in Wightman Fork near the Summitville Mine site. Discharge was determined and metal concentrations at 38...
Comparison of Hydrologic Data from Monroe County, Michigan, 1991-2001
J.R. Nicholas, Stephen P. Blumer, Rose M. McGowan
2001, Open-File Report 2001-498
In the summer of 2001, there were renewed concerns about the effects of quarry dewatering on nearby domestic ground-water supplies in Monroe County, Michigan. Reports of domestic wells “going dry” are not uncommon historically in Monroe County. Such reports have been linked to droughts, nearby irrigation, quarrying, and other large...
Average annual precipitation classes to characterize watersheds in North Carolina
Silvia Terziotti, Jo Leslie Eimers
2001, Open-File Report 01-494
This web site contains the Federal Geographic Data Committee-compliant metadata (documentation) for digital data produced for the North Carolina, Department of Environment and Natural Resources, Public Water Supply Section, Source Water Assessment Program. The metadata are for 11 individual Geographic Information System data sets. An overlay and indexing method was...
Water resources data, Arizona, water year 2000
S. Tadayon, N.R. Duet, G. G. Fisk, H.F. McCormack, C.K. Partin, G.L. Pope, P.D. Rigas
2001, Water Data Report AZ-00-1
The Water Resources Division of the U.S. Geological Survey (USGS), in cooperation with State agencies, obtains a large amount of data on the water resources of Arizona each water year. These data, accumulated during many water years, constitute a valuable data base for developing an improved understanding of the water...
Measurement of delta13C and delta18O Isotopic Ratios of CaCO3 by a Thermoquest Finnigan GasBench II Delta Plus XL Continous Flow Isotope Ratio Mass Spectrometer with Application to Devils Hole Core DH-11 Calcite
Kinga M. Revesz, Jurate Maciunas Landwehr, Jaroslav Edward Keybl
2001, Open-File Report 2001-257
A new method was developed to analyze the stable carbon and oxygen isotope ratios of small samples (400?20 ?g) of calcium carbonate. This new method streamlines the classical phosphoric acid - calcium carbonate (H3PO4 - CaCO3) reaction method by making use of a Thermoquest-Finnigan GasBench II preparation device and a...
Seven-year phenological record of the Alaskan ecoregions derived from advanced very high resolution radiometer normalized difference vegetation index data
Carl J. Markon
2001, Open-File Report 2001-11
Seasonal properties of vegetation covering northern boreal and arctic landscapes are considered important as input to numerous climate change studies. In this study, multitemporal phenological characteristics of Alaskan vegetation were studied for the State as a whole, and 19 of 20 ecoregions were studied using seasonally truncated, composited advanced very...
Water resources data, Oklahoma, water year 2000: Volume 2. Red River Basin and ground-water wells
R.L. Blazs, D.M. Walters, T.E. Coffey, D.L. Boyle, J.J. Wellman
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...
USGS GeoData Digital Orthophoto Quadrangles
Water Resources Division, U.S. Geological Survey
2001, Fact Sheet 057-01
A digital orthophoto quadrangle (DOQ) is a computer-generated image of an aerial photograph in which image displacement caused by terrain relief and camera tilts has been removed. It combines the image characteristics of a photograph with the geometric qualities of a map....

Evaluation of Metal Toxicity in Streams Affected by Abandoned Mine Lands, Upper Animas River Watershed, Colorado
John M. Besser, Ann L. Allert, Douglas K. Hardesty, Christopher G. Ingersoll, Thomas W. May, Ning Wang, Kenneth J. Leib
2001, Biological Science Report 2001-0001
Acid drainage from abandoned mines and from naturally-acidic rocks and soil in the upper Animas River watershed of Colorado generates elevated concentrations of acidity and dissolved metals in stream waters and deposition of metal-contaminated particulates in streambed sediments, resulting in both toxicity and habitat degradation for stream biota. High concentrations...
