Hydrogeologic framework of the New Jersey Coastal Plain
Otto S. Zapecza
1989, Professional Paper 1404-B
This report presents the results of a water-resources, oriented subsurface mapping program within the Coastal Plain of New Jersey. The occurrence and configuration of 15 regional hydrogeologic units have been defined, primarily on the basis of an interpretation of borehole geophysical data. The nine aquifers and six...
Water resources of Soledad, Poway, and Moosa basins, San Diego County, California
K. D. Evenson
1989, Water-Resources Investigations Report 88-4030
Reclaimed water is being considered as as supplemental water supply in the Soledad, Poway, and Moosa basins, San Diego County. This report describes the geology, soils, hydrology, and cultural factors in each of the basins as they relate to use of reclaimed water. Imported water is currently the major water-supply...

Ground-water hydrology of the central Raton Basin, Colorado and New Mexico
Arthur L. Geldon
1989, Water Supply Paper 2288
The watersheds of the Purgatoire and Apishapa Rivers contain most of the public coal lands in the Raton Basin. The U.S. Geological Survey, in cooperation with the U.S. Bureau of Land Management, investigated the hydrogeology of this area from 1978 to 1982, inventorying 231 wells, 38 springs, and 6 mines,...
Hydrology of the Oakley Fan Area, south-central Idaho
H.W. Young, G. D. Newton
1989, Water-Resources Investigations Report 88-4065
The Oakley Fan area is a broad, crescent-shaped lowland along the southern margin of the Snake River Plain in south-central Idaho. Intensive groundwater development for irrigation has resulted in rapid water-level declines and, as a consequence, designation by the State of four Critical Groundwater Areas. Principal aquifers are in limestone,...
Geohydrology of the Escondido hydrologic subarea, San Diego County, California
L. R. Woolfenden
1989, Water-Resources Investigations Report 88-4223
The San Diego region of California is undergoing rapid growth with a corresponding increase in the demand for water. To update the basin plan developed in 1975 by the California Regional Water Quality Control Board, San Diego Region, water-level and water quality data for the 44-sq mi Escondido hydrologic subarea...
Surface-water quality in the West Branch Susquehanna River basin, Pennsylvania: An appraisal of areal and temporal variability from 1962 to 1982 in hydrologic accounting unit 020502
R.A. Hainly, J.F. Truhlar, K. L. Wetzel
1989, Water-Resources Investigations Report 85-4283
The West Branch Susquehanna River basin has a drainage area of 6,955 square miles in north-central Pennsylvania and comprises Hydrologic Accounting Unit 020502. A National Stream Quality Accounting Network (NASQAN) waterquality data collection site, maintained by the U.S. Geological Survey, is located on the river near its mouth at Lewisburg,...
Trend analysis of Lake Parker stage and relation to various hydrologic factors, 1950-86, Lakeland, Florida
S.E. Henderson, M. A. Lopez
1989, Water-Resources Investigations Report 89-4037
Kendall tau test and regression analysis were used to determine if statistically significant long-term trends exist for Lake Parker, Florida stage data or for four other area lakes, four groundwater sites, four rainfall sites, Lakeland public-supply pumpage, and pan evaporation. A 10% significance level was used for criterion of an...
Estimating pumping time and ground-water withdrawals using energy- consumption data
R. T. Hurr, D. W. Litke
1989, Water-Resources Investigations Report 89-4107
Evaluation of the hydrology of an aquifer requires knowledge about the volume of groundwater in storage and also about the volume of groundwater withdrawals. Totalizer flow meters may be installed at pumping plants to measure withdrawals; however, it generally is impractical to equip all pumping plants in an area with...
Analysis of the effect of pumping on ground-water flow in the Springfield Plateau and Ozark aquifers near Springfield, Missouri
J. L. Imes
1989, Water-Resources Investigations Report 89-4079
Pumpage of water from the Ozark aquifer for public supply and industry use by the city of Springfield and surrounding communities in southwestern Missouri has significantly altered the potentiometric surface of the aquifer. Springfield is located on a regional groundwater divide that trends east and west across southern Missouri. Groundwater...
Estimating flood hydrographs for Arkansas streams
B.L. Neely Jr.
1989, Water-Resources Investigations Report 89-4109
Flood hydrographs are needed for the design of many highway drainage structures and embankments and flood water storage structures. A dimensionless hydrograph is presented for Arkansas streams having drainage areas < 600 sq mi. This dimensionless hydrograph can be used with peak discharge and equivalent lagtime to determine flood hydrographs...
Simulation of streamflow in small drainage basins in the southern Yampa River basin, Colorado
R. S. Parker, J. M. Norris
1989, Water-Resources Investigations Report 88-4071
Coal mining operations in northwestern Colorado commonly are located in areas that have minimal available water-resource information. Drainage-basin models can be a method for extending water-resource information to include periods for which there are no records or to transfer the information to areas that have no streamflow-gaging stations. To evaluate...
Aquifer tests in the flood-plain alluvium and Santa Fe group at the Rio Grande near Canutillo, El Paso County, Texas
Edward L. Nickerson
1989, Water-Resources Investigations Report 89-4011
An aquifer system consisting of the Rio Grande flood-plain alluvium and Santa Fe Group underlying the southern Mesilla Valley in Dona Ana County, New Mexico and El Paso County, Texas has become an important source of water for both municipal and agricultural uses. Determination of aquifer properties is essential in...
Hydrology of the Castle Lake blockage, Mount St. Helens, Washington
William Meyer, M. A. Sabol
1989, Water-Resources Investigations Report 87-4272
The debris avalanche that occurred during the May 19, 1980, eruption of Mount St. Helens blocked South Fork Castle Creek and created Castle Lake. Stability of the blockage was of concern, and a digital model that simulates three-dimensional groundwater movement in the blockage was constructed as part of the analysis...
Hydrology of the Prospector Square area, Summit County, Utah
J. L. Mason
1989, Water-Resources Investigations Report 88-4156
The Silver Creek tailings site is in Prospector Square, a commercial development and residential community in Summit County, Utah. This study assessed the presence of metals and the movement of groundwater in the unconsolidated valley-fill and consolidated-rock aquifers underlying the tailings. The unconsolidated valley fill is a poorly sorted mixture...
