D. K. Yobbi, W. M. Woodham, George R. Schiner
1980, Open-File Report 80-587
A May 1980 potentiometric-surface map of the Southwest Florida Water Management District depicts the annual low water-level period. Potentiometric levels decreased 5 to 36 feet between September 1979 and May 1980, in the citrus and farming sections of southern Hillsborough, southwestern Polk, northwestern DeSoto , Hardee, and Manatee Counties. Water...
Experiments using a convertible data collection platform
Stanley R. Addess
1980, Open-File Report 80-123
Experiments under the sponsorship of the U.S. Geological Survey in the use of a convertible data collection platform (CDCP) were performed by 13 organizations. Success in its use was related directly to the resources applied by the experimenter. After design faults were corrected by the manufacturer, most of the problems...
Water resources and geology of the Los Coyotes Indian Reservation and vicinity, San Diego County, California
A.P. Ballog Jr., W. R. Moyle Jr.
1980, Open-File Report 80-960
The water resources of the Los Coyotes Indian Reservation, San Diego County, Calif., are sufficient to supply the limited domestic and stock-water needs of the present residents of the reservation. Surface-water runoff is derived from direct precipitation on the area and from intermittent spring flow. Groundwater occurs in the alluvial...

1980, Open-File Report 80-138
As part of a continuing program by the U.S. Geological Survey to collect and chemically analyze representative samples of U.S. coals, 26 coal samples were collected from the Cretaceous Dakota and Straight Cliffs Formations, Southwestern Utah Region, Kane and Garfield Counties, Utah. Seven samples are from four core holes in...
Seismic refraction data for shots recorded in the Coso Range, California, October 1976
A. W. Walter, Craig S. Weaver
1980, Open-File Report 80-186
The Coso Range lies in the southwest corner of the Basin and Range province, east of the Sierra Nevada and north of the Garlock Fault. The range, circular in form, is covered by a thin sequence of late-cenozoic volcanics which overlie highly fractured crystalline basement, similar in composition to the...
Ground water in the Piedmont Upland of central Maryland
Claire A. Richardson
1980, Water-Resources Investigations Report 80-18
Aquifers in a 130-square-mile area of the central Maryland and Piedmont, are shown to be the sole or principal source of water. The study area is underlain chiefly by crystalline rocks and partly by unaltered sandstones and siltstones. The groundwater is derived from local precipitation and generally occurs under water-table...
