Water use in Arkansas, 1981
A.P. Hall, T.W. Holland
1984, Water-Resources Investigations Report 84-4070
Water use and consumption data for 1981 are presented by county and source. Use-data are presented by category for each county. Total water use, excluding wildlife impoundments, was 32,970 million gallons per day, which was 19 percent less than in 1980; consumption was 4,610 million gallons per day. Ground water...
Generalized potentiometric-surface map of the High Plains aquifer in Wyoming, 1981
Charles Avery, Robert A. Pettijohn
1984, Water-Resources Investigations Report 84-4033
A potentiometric-surface map shows the general configuration of the water surface for the High Plains Aquifer, which is composed of Oligocene age and younger rocks in southeastern Wyoming. The potentiometric contours are shown at 100-foot intervals on a map at a scale of 1:250,000. The High Plains Aquifer in Wyoming...
Average annual precipitation and runoff for Arkansas, 1951-80
David A. Freiwald
1984, Water-Resources Investigations Report 84-4363
Ten intercomparison studies to determine the accuracy of pH and specific-conductance measurements, using dilute-nitric acid solutions, were managed by the U.S. Geological Survey for the National Atmospheric Deposition Program and the National Trends Network precipitation networks. These precipitation networks set quality-control goals for site-operator measurements of pH and specific conductance....
Vertical crustal movements in Southern California, 1974 to 1978
Robert O. Burford, Thomas D. Gilmore
1984, Circular 905
An extensive resurvey of most of the first-order leveling network in southern California, known as the Southern California Releveling Program (SCRP), was carried out during the first 5 months of 1978. The primary scientific purpose of these measurements was to rapidly update the vertical control record throughout a recently uplifted...
Ice volumes on Cascade volcanoes: Mount Rainier, Mount Hood, Three Sisters, and Mount Shasta
C. L. Driedger, P.M. Kennard
1984, Open-File Report 84-581
During the eruptions of Mount St. Helens the occurrence of floods and mudflows made apparent the need for predictive water-hazard analysis of other Cascade volcanoes. A basic requirement for such analysis is information about the volumes and distributions of snow and ice on other volcanoes.A radar unit contained in a...
Potentiometric surface of the upper Floridan aquifer in the St. Johns River Water Management District and vicinity, Florida, May 1984
George R. Schiner, Eugene C. Hayes
1984, Open-File Report 84-801
This map shows the potentiometric surface of the Upper Floridan aquifer in the St. Johns River Water Management District and vicinity for May 1984. The Upper Floridan aquifer is the principal source of potable water in the area. Water-level measurements were made on approximately 1,000 wells and on several springs....
Approximate water-level changes in wells in the Chicot and Evangeline aquifers, 1977-84 and 1983-84, and measured compaction, 1973-84, in the Houston-Galveston region, Texas
Jeffrey L. Strause
1984, Open-File Report 84-140
This report, which was prepared in cooperation with the City of Houston and Harris-Galveston Coastal Subsidence District, presents data on water-level changes during 1977-84 and 1983-84 in the Chicot and Evangeline aquifers (figs. 1-4) and data on measured compaction 1973-84 (fig. 5). Water levels in about 550 wells were used to...
