Selected nutrients in stormwater runoff from Davenport, Iowa, 1992
B.D. Schaap, K.J. Lucey
1994, Water-Resources Investigations Report 94-4130
Flow-weighted composite samples of stormwater runoff from areas of different land use in Davenport, Iowa, were collected in the summer and fall of 1992 and analyzed for selected nutrients. Annual constituent loads were estimated for the area drained by the Davenport storm-sewer network. In all cases, the regression-equation estimate of...
Sources of trends in water-quality data for selected streams in Texas, 1975-89 water years
T. L. Schertz, F.C. Wells, D.J. Ohe
1994, Water-Resources Investigations Report 94-4213
Sources of trends in water-quality data for selected streams in Texas for the 1975-89 water years were investigated in this study. The investigation of sources was confined to distinct geographic patterns in the trend indicators for one constituent or for a group of related constituents. The probable source of trend patterns...
Tritium, stable isotopes, and nitrogen in flow from selected springs that discharge to the Snake River, Twin Falls-Hagerman area, Idaho, 1990-93
L. J. Mann, W. H. Low
1994, Water-Resources Investigations Report 94-4247
In 1990-93, water from 19 springs along the north side of the Snake River near Twin Falls and Hagerman contained from 9.2+0.6 to 78.4+5.1 picocuries per liter (pCi/L) of tritium. The springs were placed into three categories based on their locations and tritium concentrations: Category I was the upstream most...
Physical characteristics of stream subbasins in the Lac qui Parle River basin, southwestern Minnesota and eastern South Dakota
D. L. Lorenz, C. A. Sanocki, Thomas A. Winterstein
1994, Open-File Report 93-46
Data describing the physical characteristics of stream subbasins upstream from selected points on streams in the Lac qui Parle River basin, located in southwestern Minnesota and eastern South Dakota, are presented in this report. The physical charac- teristics are the drainage area of the subbasin, the percentage area of the...
Evidence of prehistoric flooding and the potential for future extreme flooding at Coyote Wash, Yucca Mountain, Nye County, Nevada
Patrick A. Glancy
1994, Open-File Report 92-458
Coyote Wash, east of Yucca Mountain and southwest of the Nevada Test Site, is the potential location for an exploratory shaft to investigate the feasibility of underground storage of radioactive waste. The potential for flooding and related fluvial-debris hazards was investigated with respect to the potential shaft location. Trenches excavated...
Global energy and water cycle experiment (GEWEX) continental-scale international project (GCIP); reference data sets CD-ROM
Alan Rea, Joel R. Cederstrand
1994, Open-File Report 94-388
The data sets on this compact disc are a compilation of several geographic reference data sets of interest to the global-change research community. The data sets were chosen with input from the Global Energy and Water Cycle Experiment (GEWEX) Continental-Scale International Project (GCIP) Data Committee and the GCIP Hydrometeorology and...
Physical characteristics of stream subbasins in the Chippewa River basin, west-central Minnesota
Chris Sanocki, James R. Krumrie
1994, Open-File Report 94-488
Data that describe the physical characteristics of stream subbasins upstream from selected points on streams in the Chippewa River Basin, located in west-central Minnesota, are presented in this report The physical characteristics are the drainage area of the subbasin, the percentage area of the subbasin covered only by lakes, the...
Data on natural organic substances in dissolved, colloidal, suspended-silt and -clay, and bed-sediment phases in the Mississippi River and some of its tributaries, 1987-90
J.A. Leenheer, T.I. Noyes, P.A. Brown
1994, Water-Resources Investigations Report 93-4204
The Mississippi River and some of its tributaries were sampled for natural organic substances dissolved in water and in suspended and bed sediments during seven sampling cruises from 1987-90. The sampling cruises were made during different seasons, in the free-flowing reaches of the river from St. Louis, Missouri, to New...
Nitrate in ground water and spring water near four dairy farms in North Florida, 1990-93
W. J. Andrews
1994, Water-Resources Investigations Report 94-4162
Concentrations of nitrate and other selected water- quality characteristics were analyzed periodically for two years in water from 51 monitoring wells installed at four farms and in water discharging from three nearby springs along the Suwannee River in Lafayette and Suwannee Counties to examine the quality of ground water at...
Sources and cycling of major ions and nutrients in Devils Lake, North Dakota
R.M. Lent
1994, Water-Resources Investigations Report 94-4171
Devils Lake is a saline lake in a large, closed drainage basin in northeastern North Dakota. Previous studies determined that major-ion and nutrient concentrations in Devils Lake are strongly affected by microbially mediated sulfate reduction and dissolution of sulfate and carbonate minerals in the bottom sediments. These studies documented substantial...
Geologic history and hydrogeologic setting of the Edwards-Trinity aquifer system, west-central Texas
R.A. Barker, P. W. Bush, E.T. Baker
1994, Water-Resources Investigations Report 94-4039
The Edwards-Trinity aquifer system underlies about 42,000 square miles of west-central Texas. Nearly flat-lying, mostly Comanche (Lower Cretaceous) strata of the aquifer system thin northwestward atop massive pre-Cretaceous rocks that are comparatively impermeable and structurally complex. From predominately terrigenous clastic sediments in the east and fluvialdeltaic (terrestrial) deposits in the...
Ground-water flow and quality, and geochemical processes, in Indian Wells Valley, Kern, Inyo, and San Bernardino counties, California, 1987-88
Charles Berenbrock, R. A. Schroeder
1994, Water-Resources Investigations Report 93-4003
An existing water-quality data base for the 300- square-mile Indian Wells Valley was updated by means of chemical and isotopic analysis of ground water. The wide range in measured concentrations of major ions and of minor constituents such as fluoride, borate, nitrate, manganese, and iron is attributed to geochemical reactions...
