The hydrologic bench-mark program; a standard to evaluate time-series trends in selected water-quality constituents for streams in Georgia
G. R. Buell, S.C. Grams
1985, Water-Resources Investigations Report 84-4318
Significant temporal trends in monthly pH, specific conductance, total alkalinity, hardness, total nitrite-plus-nitrite nitrogen, and total phosphorus measurements at five stream sites in Georgia were identified using a rank correlation technique, the seasonal Kendall test and slope estimator. These sites include a U.S. Geological Survey Hydrologic Bench-Mark site, Falling Creek...
Survey of Fena Reservoir, Island of Guam: Limnological reconnaissance
J. W. LaBaugh
1985, Water-Resources Investigations Report 83-4241
During the limnological reconnaissance of Fena Reservoir, samples of the water columns and bottom sediment were obtained and analyzed at five locations within the reservoir. Major ion analyses of filtered surface water indicated that calcium and bicarbonate are the dominant cation and anion in the reservoir. Thermal stratification was recorded...
Traveltime, longitudinal-dispersion, reaeration, and basin characteristics of the White River, Colorado and Utah
J. M. Boyle, N.E. Spahr
1985, Water-Resources Investigations Report 85-4050
Traveltime and longitudinal-dispersion characteristics were measured for the White River using dye tracers. Discharges ranged from 281 to 1,840 cubic feet per second and velocities ranged from 1.26 to 3.17 miles per hour. Traveltimes were determined for discharges other than measured discharges by a graphical method and a linear-regression method....
Estimating average base flow at low-flow partial-record stations on the south shore of Long Island, New York
H. T. Buxton
1985, Water-Resources Investigations Report 84-4240
Base flows of the 29 major streams in southeast Nassau and southwest Suffolk Counties, New York, were statistically analyzed to discern the correlation among flows of adjacent streams. Concurrent base-flow data from a partial-record and a nearby continuous-record station were related; the data were from 1968-75, a period near hydrologic...
Techniques for estimating flood peak discharges for unregulated streams and streams regulated by small floodwater retarding structures in Oklahoma
R. L. Tortorelli, D. L. Bergman
1985, Water-Resources Investigations Report 84-4358
Statewide regression relations for Oklahoma were determined for estimating peak discharge of floods for selected recurrence intervals from 2 to 500 years. The independent variables required for estimating flood discharge for rural streams are contributing drainage area and mean annual precipitation. Main-channel slope, a variable used in previous reports, was...
A two-constituent solute-transport model for ground water having variable density
W. E. Sanford, Leonard F. Konikow
1985, Water-Resources Investigations Report 85-4279
A numerical model has been developed to simulate solute transport and dispersion of either one or two constituents in groundwater where there is two-dimensional, density-dependent flow. The model is a modified version of the one documented by Konikow and Bredehoeft (1978), which uses finite-difference methods and the method of characteristics...
Dissolved constituents including selenium in waters in the vicinity of Kesterson National Wildlife Refuge and the west grassland, Fresno and Merced Counties, California
T. S. Presser, Ivan Barnes
1985, Water-Resources Investigations Report 85-4220
Analyses were made for dissolved constituents including selenium (Se) in waters associated with subsurface agricultural drainage from the western San Joaquin Valley of California. In the vicinity of Kesterson National Wildlife Refuge and the Grassland wetlands area Se was found to be mobilized in water. As a consequence of this...

Maps of the Bonsall area of the San Luis Rey River valley, San Diego County, California, showing geology, hydrology, and ground-water quality
John A. Izbicki
1985, Water-Resources Investigations Report 85-4112
In November 1984, 84 wells and 1 spring in the Bonsall area of the San Luis Rey River valley were inventoried by U.S. Geological Survey personnel. Depth to water in 38 wells ranged from 1.3 to 38 ft and 23 wells had depths to water less than 10 feet. Dissolved...
Arsenic, nitrate, iron, and hardness, in ground water, Goldstream Road, Yankovich Road, and Murphy Dome Road areas, (T.1N, R.2W, FM), Fairbanks, Alaska
Gary C. Hopkins, Kevin F. Maxwell
1985, Open-File Report 85-341
Arsenic, nitrate, iron, and hardness in well water are concerns of homeowners and planners in the Fairbanks North Star Borough, Alaska. Arsenic and nitrate in water may affect human health. Iron and hardness can be aesthetically objectionable, impair plumbing systems, and discolor plumbing fixtures. This report is a compilation of...
Potentiometric surface of the upper Floridan Aquifer, west-central Florida, September 1985
G. L. Barr
1985, Open-File Report 85-679
The potentiometric surface is the level to which water will rise in tightly cased wells that tap the Upper Floridan aquifer. The surface is mapped by determining the altitude of water levels in a network of wells and is represented on maps by contours that connect points of equal altitude....

Water budget and estimated suspended-sediment inflow for Reelfoot Lake, Obion and Lake Counties, Northwestern Tennessee, May 1984-April 1985
Clarence H. Robbins
1985, Water-Resources Investigations Report 85-4284
Reelfoot Lake in northwestern Tennessee, with a surface area of 15,500 acres at normal pool elevation, is the largest natural lake in Tennessee. Over the years, the lake has become an important economic, environmental, and recreational resource to the people in the area, and to the State of Tennessee. The...
Occurrence of ground water and potential for seawater intrusion, Island County, Washington
M. A. Jones
1985, Water-Resources Investigations Report 85-4046
The data from a study of groundwater availability and quality in Island County, Washington, are presented. Increased groundwater withdrawals associated with the population increase in Island County have caused concern about groundwater availability and potential seawater intrusion. The most widely used aquifer lies near sea level. Locally, available data indicate...

H. H. Bauer, John J. Vaccaro, R. C. Lane
1985, Water-Resources Investigations Report 84-4360
A 2 1/2-year study of the Columbia Plateau in Washington was begun in March 1982 to define spatial and temporal variations in dissolved sodium in aquifers of the Columbia River Basalt Group and to relate these variations to the groundwater system and its geologic framework. This report is part of...

D. Briane Adams, Yvonne E. Stoker
1985, Water-Resources Investigations Report 84-4149
The study conducted during 1982-83, documents hydrologic conditions in Lake Placid and surrounding areas of Florida. Lake-stage data indicate that the 2- to 50-year flood stage ranges from 93.9 to 96.2 ft. Lake stage is reflected by annual departure of precipitation of the previous year from long-term average. A bathymetric...
