M.F. Becker
1997, Open-File Report 97-828
In 1995 the Oklahoma Department of Wildlife Conservation acquired a drained wetland in southwest Oklahoma known as Hackberry Flat. Following restoration by Wildlife Conservation the wetland will be used by migratory birds and waterfowl. If naturally occurring trace metals and residual organic compounds from agriculture and industry were present, they...
Estimation of peak-discharge frequency of urban streams in Jefferson County, Kentucky

1997, Water-Resources Investigations Report 97-4219
An investigation of flood-hydrograph characteristics for streams in urban Jefferson County, Kentucky, was made to obtain hydrologic information needed for waterresources management. Equations for estimating peak-discharge frequencies for ungaged streams in the county were developed by combining (1) long-term annual peakdischarge data and rainfall-runoff data collected from 1991 to 1995...

Water Budget for the Iao Area, Island of Maui, Hawaii
Patricia J. Shade
1997, Water-Resources Investigations Report 97-4244
Ground-water recharge is estimated as the residual component of a monthly water budget calculated using soil characteristics and long-term average rainfall, streamflow, irrigation, and pan-evaporation data. The water-budget components of rainfall, direct runoff, evapotranspiration, and ground-water recharge are defined seasonally, through the use of monthly data, and spatially by land-use...
Detection of underground voids in Ohio by use of geophysical methods
Jens Munk, R. A. Sheets
1997, Water-Resources Investigations Report 97-4221
Geophysical methods are generally classified as electrical, potential field, and seismic methods. Each method type relies on contrasts of physical properties in the subsurface. Forward models based on the physical properties of air- and water-filled voids within common geologic materials indicate that several geophysical methods are technically feasible for detection...
Water-quality assessment of the Lower Susquehanna River Basin, Pennsylvania and Maryland: sources, characteristics, analysis and limitations of nutrient and suspended-sediment data, 1975-90
R.A. Hainly, C. A. Loper
1997, Water-Resources Investigations Report 97-4209
This report describes analyses of available information on nutrients and suspended sediment collected in the Lower Susquehanna River Basin during water years 1975-90. Most of the analyses were applied to data collected during water years 1980-89. The report describes the spatial and temporal availability of nutrient and suspended-sediment data and...
Evaluation of the U.S. Geological Survey Ground-Water Data-Collection Program in Hawaii, 1992
Stephen S. Anthony
1997, Water-Resources Investigations Report 97-4232
In 1992, the U.S. Geological Survey ground-water data-collection program in the State of Hawaii consisted of 188 wells distributed among the islands of Oahu, Kauai, Maui, Molokai, and Hawaii. Water-level and water-quality (temperature, specific conductance, and chloride concentration) data were collected from observation wells, deep monitoring wells that penetrate the...
Water-quality assessment of the Rio Grande Valley, Colorado, New Mexico, and Texas: Summary and analysis of water-quality data for the basic-fixed-site network, 1993-95
D. F. Healy
1997, Water-Resources Investigations Report 97-4212
The Rio Grande Valley study unit of the U.S. Geological Survey National Water-Quality Assessment Program collected monthly water- quality samples at a network of surface-water sites from April 1993 through September 1995. This basic-fixed-site network consisted of nine main-stem sites on the Rio Grande, five sites on tributaries of the...
Analysis of bottom sediment to estimate nonpoint-source phosphorus loads for 1981-96 in Hillsdale Lake, northeast Kansas
K. E. Juracek
1997, Water-Resources Investigations Report 97-4235
Bottom sediment in Hillsdale Lake, northeast Kansas, was analyzed as a means of estimating the annual load of total phosphorus deposited in the lake from nonpoint sources. Topographic, bathymetric, and sediment-core data were used to estimate the total mass of phosphorus in the lake-bottom sediment. Available streamflow and water-quality data...
Statistical analysis of nitrate in ground water, West Salt River Valley, Arizona
Andy E. Long, James G. Brown, Dorinda J. Gellenbeck
1997, Water-Resources Investigations Report 97-4185
Accurate estimates of the nitrate concentrations in ground water in west Salt River Valley are needed to better manage ground water affected by nitrate. Statistical analyses were done to establish the best statistical method to produce these estimates. Three sets of ground-water data for different time periods --1975-77, 1980-85, and...

Evaluation of bridge-scour data at selected sites in Ohio
K.S. Jackson
1997, Water-Resources Investigations Report 97-4182
Scour data collected during 1989-94 were evaluated to determine whether pier scour and contraction scour occurred at 22 bridge sites in Ohio. Pier-scour depths computed from selected pier-scour prediction equations were compared with measured pier-scour depths, and the accuracy of the prediction equations were evaluated. Observed pier-scour relations were compared...
