Water resources of Brookings and Kingsbury counties, South Dakota
L.J. Hamilton
1989, Water-Resources Investigations Report 88-4185
Surface water and groundwater resources are widely distributed in Brookings and Kingsbury Counties, an area of nearly 1,700 sq mi of glaciated plains of the Coteau des Prairies plateau in eastern South Dakota. The resources are relatively undeveloped except for large withdrawals for irrigation from shallow glacial aquifers. Groundwater withdrawals...
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...
Review of edgematchimg procedures for digital cartographic data used in Geographic Information Systems (GIS)
D.D. Nebert
1989, Open-File Report 89-579
In the process of developing a continuous hydrographic data layer for water resources applications in the Pacific Northwest, map-edge discontinuities in the U.S. Geological Survey 1:100 ,000-scale digital data that required application of computer-assisted edgematching procedures were identified. The spatial data sets required by the project must have line features...
Approximate altitude of water levels in wells in the Chicot and Evangeline aquifers in the Houston area, Texas, spring 1989
Dana L. Barbie, L.S. Coplin, C.W. Bonnet
1989, Open-File Report 89-237
This report shows the altitudes of water levels in the Chicot and Evangeline aquifers in the Houston metropolitan area, Texas. Of the 425 wells measured, 307 were used to construct the maps of potentiometric surface. The Chicot and Evangeline aquifers are composed of several sand layers, each with a separate potentiometric...
Estimation of the recharge area of a pumped, stratified-drift aquifer in Connecticut by simulation modeling
D. L. Mazzaferro
1989, Water-Resources Investigations Report 87-4124
Groundwater quality management plans in Connecticut require information about the size and shape of recharge areas that contribute flow to pumping centers in extensive, stratified-drift aquifers. Flow models of a hypothetical aquifer , and a stratified-drift aquifer in Farmington are used to evaluate how contributing areas change in response to...
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...
Geohydrology and susceptibility of aquifers to surface contamination in Alabama; area 5
R. E. Kidd
1989, Water-Resources Investigations Report 88-4083
The U.S. Geological Survey, in cooperation with the Alabama Department of Environmental Management, is conducting a series of geohydrologic studies to delineate the major aquifers and their susceptibility to contamination in Alabama. This report delineates and describes the geohydrology and susceptibility of the major aquifers to contamination in Area 5--Chambers,...
Simulation of ground-water flow at Anchorage, Alaska, 1955-83
Leslie Patrick, T. P. Brabets, R. L. Glass
1989, Water-Resources Investigations Report 88-4139
The groundwater system at Anchorage, Alaska was analyzed by using a two-layer three-dimensional mathematical model. By use of existing data, both nonpumping and pumping steady-state conditions and transient conditions were simulated. Under steady-state conditions, calculated directions of groundwater flow were similar to observed flow patterns, and calculated stream discharges generally...
Hypolimnetic concentrations of dissolved oxygen, nutrients, and trace elements in Coeur d'Alene Lake, Idaho
P. F. Woods
1989, Water-Resources Investigations Report 89-4032
A reconnaissance study of Coeur d'Alene Lake, Idaho done from May through November 1987 assessed water quality throughout the lake. Particular emphasis was on hypolimnetic concentrations of dissolved oxygen, nutrients, and trace elements. Study results enabled refinement of the sampling protocol in a U.S. Geological Survey research proposal for a...
Flood of December 25, 1987, in Millington, Tennessee and vicinity
James G. Lewis, Charles R. Gamble
1989, Water-Resources Investigations Report 89-4019
Intense rainfall totaling 9.2 in. in a 12-hour period on December 24-25, 1987, and 14.8 in for the period December 24-27 caused record floods in Millington, Tennessee and vicinity. The peak discharge of Big Creek at Raleigh-Millington Road was almost twice the discharge of the 100-year flood discharge and that...
Description of data files compiled for the Central Midwest Regional Aquifer-System Analysis
John O. Helgesen, Cristi V. Hansen
1989, Open-File Report 89-42
Several types of geologic and hydrologic data were collected and compiled as part of the Central Midwest Regional Aquifer-System Analysis. The study described the hydrology of Cambrian-age through Cretaceous-age rocks in all of Kansas and Nebraska and parts of eight other states. Information from both water wells and petroleum wells...
Compilation of geohydrologic data collected as part of the areal appraisal of ground-water resources near Branson, Missouri
J. L. Imes
1989, Open-File Report 89-401
A rapidly developing retirement community and tourist industry in the Branson, Missouri area has created an increased demand for potable water, especially in the summer months. The rapid pace of residential and business expansion has created concerns regarding the future groundwater availability and quality. Water levels measured in the Ozark...
