Characterization of selected radionuclides in sediment and surface water in Standley Lake, Great Western Reservoir, and Mower Reservoir, Jefferson County, Colorado, 1992
D. W. Clow, D. A. Johncox
1995, Water-Resources Investigations Report 95-4126
Lake sediment and surface water from Standley Lake, Great Western Reservoir, and Mower Reservoir, near Denver, Colorado, were sampled and analyzed for selected radionuclides during August through October, 1992. Sample concentrations were summarized and compared to results from a study conducted in 1983-84. Median plutonium-239,240 (239,240Pu) concentrations in lake-sediment...
The strategy for improving water-quality monitoring in the United States; final report of the Intergovernmental Task Force on Monitoring Water Quality; technical appendices
Intergovernmental Task Force on Monitoring Water Quality
1995, Open-File Report 95-742
The Intergovernmental Task Force on Monitoring Water Quality (ITFM) prepared this report in collaboration with representatives of all levels of government and the private sector. The report recommends a strategy for nationwide water-quality monitoring and technical monitoring improvements to support sound water-quality decisionmaking. The strategy is intended to achieve a...
Nutrient loading to Lewisville Lake, north-central Texas, 1984-87
W. S. Gain, Stanley Baldys
1995, Water-Resources Investigations Report 95-4076
Concentrations of nutrients in the streams of the 1,660-square-mile Lewisville Lake drainage basin have some association with the two types of physiographic regions in the basin prairie regions and cross timbers regions. Total nitrogen and phosphorus concentrations generally are larger in streams draining the prairie regions than in streams draining...
The use of three-parameter rating table lookup programs, RDRAT and PARM3, in hydraulic flow models
C.L. Sanders Jr.
1995, Water-Resources Investigations Report 95-4090
Subroutines RDRAT and PARM3 enable computer programs such as the BRANCH open-channel unsteady-flow model to route flows through or over combinations of critical-flow sections, culverts, bridges, road- overflow sections, fixed spillways, and(or) dams. The subroutines also obstruct upstream flow to simulate operation of flapper-type tide gates. A multiplier can be...
Retention time and flow patterns in Lake Marion, South Carolina, 1984
G. G. Patterson, R.M. Harvey
1995, Water-Resources Investigations Report 95-4145
In 1984, six dye tracer tests were made on Lake Marion to determine flow patterns and retention times under conditions of high and low flow. During the high-flow tests, with an average inflow of about 29,000 cubic feet per second, the approximate travel time through the lake for the peak...
Potentiometric surface of the Magothy Aquifer in southern Maryland, September 1994
Stephen E. Curtin, Frederick K. Mack, David C. Andreasen
1995, Open-File Report 95-744
A map showing the potentiometric surface of the Magothy aquifer in the Magothy Formation of Cretaceous age in southern Maryland during September 1994 was prepared from water levels measured in 85 wells. The potentiometric surface was highest near the northwestern boundary and outcrop area of the aquifer in topographically high...
Potentiometric surface of the upper Patapsco Aquifer in southern Maryland, September 1994
Stephen E. Curtin, Frederick K. Mack, David C. Andreasen
1995, Open-File Report 95-745
A map showing the potentiometric surface of the upper Patapsco aquifer in the Patapsco Formation of Cretaceous age in southern Maryland during September 1994 was prepared from water levels measured in 43 wells. The potentiometric surface was at least 70 feet above sea level near the northwestern boundary and outcrop...
Potentiometric surface of the upper Floridan Aquifer, west-central Florida, May 1995
Patricia A. Metz, K. A. Stelman
1995, Open-File Report 95-704
The Floridan aquifer system consists of the Upper and Lower Floridan aquifers separated by a middle confining unit. The middle confining unit and the Lower Floridan aquifer generally contain highly mineralized water. In most reports on the hydrology of southwest Florida, the term "Floridan aquifer" has been applied to the...
Water Budget for the Island of Kauai, Hawaii
Patricia J. Shade
1995, Water-Resources Investigations Report 95-4128
A geographic information system model was created to calculate a monthly water budget for the island of Kauai. Ground-water recharge is the residual component of a monthly water budget calculated using long-term average rainfall, streamflow, and pan-evaporation data, applied irrigation-water estimates, and soil characteristics. The water-budget components are defined seasonally,...
Ground-water quality in northeastern St. Joseph County, Indiana
J.M. Fenelon, E. Randall Bayless, Lee R. Watson
1995, Water-Resources Investigations Report 95-4092
This report describes the ground-water quality of a 220-square-mile area in northeastern St. Joseph County, Indiana. Ground-water samples were collected from 30 monitoring wells at 20 sites during May 1992; the wells were screened in either a shallow or a deep sand and gravel aquifer. Samples were analyzed for general...
Tritium and radioactive carbon (14C) analyses of gas collected from unsaturated sediments next to a low-level radioactive-waste burial site south of Beatty, Nevada, April 1994 and July 1995
David E. Prudic, Robert G. Striegl
1995, Open-File Report 95-741
Tritium activities in water vapor and radioactive carbon (14C) activities in carbon dioxide were determined in gas samples pumped from small-diameter air ports installed in a test hole within the unsaturated sediments next to a commercial burial site for low-level radioactive waste south of Beatty, Nevada. In April 1994, gas...
