The summaries for each streamflow-gaging station include (1) station...
The last interglaciation at Owens Lake, California; Core OL-92
James L. Bischoff, editor(s)
1998, Open-File Report 98-132
Owens Lake, located at the eastern base of the central Sierra Nevada (Fig. 1), was the terminus of the Owens River prior to the lake's complete desiccation shortly after 1913 due to river diversion by the City of Los Angeles. During earlier wetter cycles, the lake overflowed to fill a...
Hydrologic investigation of the Ophir Creek watershed near Yakutat, Alaska
Edward G. Neal
1998, Open-File Report 98-199
Data on streamflow and ground-water levels were collected in the Ophir Creek watershed in southeast Alaska to obtain information about the relations between streamflow, ground-water levels, and precipitation. In addition, the possible effect of an experimental channel excavation to increase flows in Ophir Creek was evaluated. Stream discharges were monitored...
Reservoir quality and diagenetic evolution of Upper Mississippian rocks in the Illinois Basin; influence of a regional hydrothermal fluid-flow event during late diagenesis
Janet K. Pitman, Mitchell E. Henry, Beverly Seyler
1998, Professional Paper 1597
Conventional reservoir quality data for more than 300 wells provided by the Illinois and Indiana State Geological Surveys were analyzed to determine the factors governing porosity and permeability in the Upper Mississippian Bethel Sandstone and Cypress Sandstone, two of the principal producing units in the Illinois Basin. In addition, approximately...
Statistical analysis and mathematical modeling of a tracer test on the Santa Clara River, Ventura County, California
Katherine S. Paybins, Tracy Nishikawa, John A. Izbicki, Eric G. Reichard
1998, Water-Resources Investigations Report 97-4275
To better understand flow processes, solute-transport processes, and ground-water/surface-water interactions on the Santa Clara River in Ventura County, California, a 24-hour fluorescent-dye tracer study was performed under steady-state flow conditions on a 28-mile reach of the river. The study reach includes perennial (uppermost and lowermost) subreaches and ephemeral subreaches of the...
Surface-water quality at fixed sites in the Western Lake Michigan Drainages, Wisconsin and Michigan, and the effects of natural and human factors, 1993-95
K.D. Richards, D. J. Sullivan, J.S. Stewart
1998, Water-Resources Investigations Report 97-4208
Streamwater samples were collected from April 1993 through July 1995 at 11 fixed sites in the Western Lake Michigan Drainages Study Unit of the U.S. Geological Survey's National Water-Quality Assessment Program. Water samples were collected monthly at all Fixed Sites, and an additional two to four samples were collected each...
Technique for simulating peak-flow hydrographs in Maryland
Jonathan J.A. Dillow
1998, Water-Resources Investigations Report 97-4279
The efficient design and management of many bridges, culverts, embankments, and flood-protection structures may require the estimation of time-of-inundation and (or) storage of floodwater relating to such structures. These estimates can be made on the basis of information derived from the peak-flow hydrograph. Average peak-flow hydrographs corresponding to a peak...
Hydrogeology and simulation of the effects of reclaimed-water application in west Orange and southeast Lake counties, Florida
Andrew M. O’Reilly
1998, Water-Resources Investigations Report 97-4199
Wastewater reclamation and reuse has become increasingly popular as water agencies search for alternative water-supply and wastewater-disposal options. Several governmental agencies in central Florida currently use the land-based application of reclaimed water (wastewater that has been treated beyond secondary treatment) as a management alternative to surface-water disposal of wastewater. Water...
Water-quality trends in the Santa Ana River at MWD Crossing and below Prado Dam, Riverside County, California
Carmen A. Burton, John A. Izbicki, Katherine S. Paybins
1998, Water-Resources Investigations Report 97-4173
The Santa Ana River, located in an extensively urbanized basin, drains about 2,670 square miles near Los Angeles, California. Almost all flow in the river, about 200,000 acre-feet annually, is diverted to ponds where it infiltrates and recharges underlying aquifers. About 2 million people are dependent on these aquifers for...
Chemistry and isotopic composition of ground water along a section near the Newmark area, San Bernardino County, California
John A. Izbicki, Wesley R. Danskin, Gregory O. Mendez
1998, Water-Resources Investigations Report 97-4179
Chemical and isotopic analyses and flow-meter measurements in pumped wells were used to determine the source, movement, and age of ground water along a section of the valley-fill aquifer from the San Jacinto Fault to the base of the San Bernardino Mountains near the Newmark area in the Bunker Hill...
Technical protocol for evaluating natural attenuation of chlorinated solvents in ground water
T.H. Wiedemeier, M.A. Swanson, D.E. Moutoux, E.K. Gordon, J.T. Wilson, B.H. Wilson, D.H. Kampbell, P.E. Haas, R.N. Miller, J.E. Hansen, Francis H. Chapelle
1998, Report
This Protocol is designed to evaluate the fate in ground water of chlorinated aliphatic hydrocarbons and/or fuel hydrocarbons. Documentation of natural attenuation requires detailed site characterization. The data collected under this protocol can be used to compare the relative effectiveness of other remedial options. and natural attenuation. This protocol should...
Estimated predevelopment discharge to streams from the High Plains Aquifer in northwestern Oklahoma, southwestern Kansas, and northwestern Texas
R. R. Luckey, M.F. Becker
1998, Water-Resources Investigations Report 97-4287
A study of the High Plains aquifer in Okla homa was initiated in 1996 to: (1) provide the information needed by the Oklahoma Water Resources Board to manage the quantity of water produced from the aquifer; and (2) provide base line water-chemistry data. The approach used to meet the first...
Natural attenuation of chlorinated-hydrocarbon contamination at Fort Wainwright, Alaska: A hydrogeochemical and microbiological investigation workplan
Kathleen A. McCarthy, Michael R. Lilly, Joan F. Braddock, Larry D. Hinzman
1998, Open-File Report 98-198
Natural attenuation processes include biological degradation, by which microorganisms break down contaminants into simpler product compounds; adsorption of contaminants to soil particles, which decreases the mass of contaminants dissolved in ground water; and dispersion, which decreases dissolved contaminant concentrations through dilution. The primary objectives of this study are to (1)...
