Operating manual for the R200 downhole recorder with Tandy 102 retriever
Roy A. Johnson, James I. Rorabaugh
1988, Open-File Report 88-488
The R200 Downhole Recorder is a battery-powered device that, when placed in a well casing, monitors water levels for a period of up to 1 year. This instrument measures a 1- to 70-ft range of water levels. These water level data can be retrieved through use of a commercially available...
Aeromagnetic maps of the Colorado River region including the Kingman, Needles, Salton Sea, and El Centro 1 degree by 2 degrees quadrangles, California, Arizona, and Nevada
John Mariano, V.J. Grauch
1988, Miscellaneous Field Studies Map 2023
Aeromagnetic data for the Colorado river region have been compiled as part of the Pacific to Arizona Crustal Experiment (PACE) Project. The data are presented here in a series of six compilations for the Kingman, Needles, Salton Sea, and El Centro 1 degree by 2 degree quadrangles, California, Arizona, and...
Ground-water hydraulics, regional flow, and ground-water development of the Floridan aquifer system in Florida and in parts of Georgia, South Carolina, and Alabama
Peter W. Bush, Richard H. Johnston
1988, Professional Paper 1403-C
The Floridan aquifer system is one of the major sources of groundwater supplies in the United States. This productive aquifer system underlies all of Florida, southeast Georgia, and small parts of adjoining Alabama and South Carolina, for a total area of about 100,000 square miles. About 3 billion gallons of...
Solute geochemistry of the Snake River plain regional aquifer system, Idaho and eastern Oregon
Warren W. Wood, Walton H. Low
1988, Professional Paper 1408-D
Four geochemical approaches were used to determine chemical reactions controlling solute concentrations in the Snake River Plain regional aquifer system: (1) calculation of a solute balance within the aquifer, (2) identification of weathered products in the aquifer frame- work, (3) comparison of thermodynamic mineral saturation indices with plausible solute reactions,...
Geohydrology, water quality, and preliminary simulations of ground-water flow of the alluvial aquifer in the upper Black Squirrel Creek basin, El Paso County, Colorado
David R. Buckles, Kenneth R. Watts
1988, Water-Resources Investigations Report 88-4017
The upper Black Squirrel Creek basin in eastern El Paso County, Colorado, is underlain by an alluvial aquifer and four bedrock aquifers. The climate of the area is semiarid, and streamflow is irregular. The alluvial aquifer has supplied water to wells since the late 1800's when ranchers first pumped water...
Water use on the Snake River plain, Idaho and eastern Oregon
S. A. Goodell
1988, Professional Paper 1408-E
Amounts of water withdrawn and consumptively used for irrigation and other uses on the Snake River Plain were estimated to help deter- mine hydrologic effects of ground- and surface-water use. Irrigation is the largest off stream use of water on the plain. Surface-water irriga- tion began in the 1840's and...
