Catalog of earthquakes in southern Alaska, January-March 1980
C.D. Stephens, K.A. Fogleman, J.C. Lahr, S.M. Helton, R.S. Cancilla, Roy Tam, J.A. Freiberg
1980, Open-File Report 80-1253
The National Center for Earthquake Research of the U.S. Geological Survey (USGS) began a program of telemetered seismic recording in south-central Alaska in 1971. The principal objectives of this program have been to use data recorded by this network to precisely locate earthquakes in the active seismic zones of southern...
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...
Makah Formation — A deep-marginal-basin sequence of late Eocene and Oligocene age in the northwestern Olympic Peninsula, Washington
P. D. Snavely, A. R. Niem, N. S. MacLeod, J. E. Pearl, W. W. Rau
1980, Professional Paper 1162-B
The Makah Formation of the Twin River Group crops out in a northwest-trending linear belt in the northwesternmost part of the Olympic Peninsula, Wash. This marine sequence consists of 2800 meters of predominantly thin-bedded siltstone and sandstone that encloses six distinctive newly named members--four thick-bedded amalgamated turbidite sandstone members, an...
Water resources data for Washington, water year 1979: Vol. 2 - Eastern Washington
Water Resources Division, U.S. Geological Survey
1980, Water Data Report WA-79-2
Water resources data for the 1979 water year for Washington consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground-water wells. This report, in two volumes, contains records for water discharge at...
Digital model simulation of the hydrologic flow system, with emphasis on ground water in Spokane Valley, Washington and Idaho
E.L. Bolke, J.J. Washington
1980, Open-File Report 80-1300
A digital-computer model of the hydrologic flow system, with emphasis on ground water, was developed for Spokane Valley, Washington and Idaho. The current rate of ground-water pumping in Spokane Valley has little effect on water levels in the Spokane aquifer, although short-term water-level declines occur locally. The model was used...
Notes on the geology of Tibet and adjacent areas; report of the American plate tectonics delegation to the People's Republic of China
A.W. Bally, Clarence R. Allen, R.B. Geyer, W.B. Hamilton, C.A. Hopson, P.H. Molnar, J.E. Oliver, N.D. Opdyke, George Plafker, F.T. Wu
1980, Open-File Report 80-501
Mean water levels in wells across Georgia were from 3.03 feet higher to 11.67 feet lower in 1979 than in 1978, and in some areas were the lowest on record. Water levels in the principal artesian aquifer underwent a long-term decline during the period 1970-79. In some areas water levels...
Potentiometric surface map of the Floridan aquifer in the St. Johns River Water Management District and vicinity, Florida, May 1979
Charles P. Laughlin, E. C. Hayes, George R. Schiner
1980, Open-File Report 80-69
This map presents the potentiometric surface of the Floridan aquifer in the St. Johns River Water Management District and vicinity for May 1979. The Floridan aquifer is the principal source of potable water in the area. Water-level measurements were made on approximately 1200 wells and on several springs. The potentiometric...
Hydrologic evaluation of a hypothetical coal-mining site near Chrisney, Spencer County, Indiana
John S. Zogorski, Daniel S. Ramey, Paul W. Lambert, Jeffrey D. Martin, Robert E. Warner
1980, Open-File Report 80-1107
Protecting the water resources of the Nation is a major emphasis of the Surface Mining Control and Reclamation Act, PL 95-87. Permanent regulations established for this Act by the Office of Surface Mining (OSM) require the issuance of a permit before mining begins. An application for a mining permit must...
Water resources data for Massachusetts and Rhode Island, water year 1979
Water Resources Division, U.S. Geological Survey
1980, Water Data Report MA-RI-79-1
Water-resources data for the 1979 water year for Massachusetts and Rhode Island consist of records of stage, discharge, and water quality of streams; contents of lakes and reservoirs; and ground-water levels. This report contains discharge records for 102 gaging stations, month end contents for 30 lakes and reservoirs, water quality...
Geohydrology of the Delta-Clearwater area, Alaska
Dorothy E. Wilcox
1980, Water-Resources Investigations Report 80-92
The alluvial aquifer in the Delta-Clearwater area, Alaska, is composed of lenticular, interbedded deposits of silt, sand, and gravel. Ground water occurs under both confined and unconfined conditions in the area. The potentiometric surface slopes approximately northward at gradients ranging from about 1 to 25 feet per mile. The aquifer...
