Map showing occurrences of spring-deposited travertine in the conterminous Western United States
J. H. Feth, Ivan Barnes
1979, Water-Resources Investigations Report 79-35
Extinct travertine terraces occur hundreds of meters above present levels of spring activity and have potentials for interpretation of ancient hydrologic systems, rates of downcutting, or rates of tectonic uplift that remain virtually unexploited. The abundance and size of extinct travertine deposits suggest that in many places, such as pinnacles...
Marine seismic sonobuoy data from the Bering Sea region
Jonathan R. Childs, Alan K. Cooper
1979, Open-File Report 79-371
Throughout the field seasons of 1975 to 1978, the Geological Survey carried out an extensive program of seismic sonobuoy research aboard the R/V S.P. LEE over the entire Bering Sea region. 75 successful sonobuoy refraction and wide angle reflection stations were recorded over the shelf areas of Navarin Basin, St....
Floods in Puerto Rico, magnitude and frequency
Miguel A. Lopez, Eloy Colon-Dieppa, Ernest D. Cobb
1979, Water-Resources Investigations Report 78-141
Annual-peak discharge records at 50 sites in Puerto Rico with five or more years of record were used to determine individual site log-Pearson type III frequency curves. The frequency curve values for 2-, 10-, 25-, 50-, and 100-year recurrence intervals at 37 sites with 10 or more years of record...
Results of transient simulations of a digital model of the Arikaree Aquifer near Wheatland, southeastern Wyoming
Dwight T. Hoxie
1979, Open-File Report 79-1280
Revised ground-water pumpage data have been imposed on a ground-water flow model previously developed for the Arikaree aquifer in a 400 square-mile area in central Platte County, Wyo. Maximum permitted annual ground-water withdrawals of 750 acre-feet for industrial use were combined with three irrigation-pumping scenarios to predict the long-term effects...
Ground-water quality in selected areas of Wisconsin
S. M. Hindall
1979, Open-File Report 79-1594
Analysis of 2,071 ground-water samples from 970 wells throughout Wisconsin indicate large variations in ground-water quality. Ground water in Wisconsin is generally suitable for most uses, but in some areas concentrations of chemical constituents exceed recommended drinking-water standards. Iron, manganese, and nitrate commonly exceed recommended drinking-water standards and dissolved solids,...
Hydrologic data for wells, springs, and streams in Boulder County, Colorado
Dennis C. Hall, Elaine L. Boyd, Doug Cain
1979, Open-File Report 79-979
Hydrologic data collected in 1975-77 as part of a comprehensive water-resources investigation of Boulder County, Colo., by the U.S. Geological Survey in cooperation with the Boulder County Health Department and the Colorado Geological Survey are presented in this report. The data, in tabular and graphic form, consist of water-quality analyses...
Surface-water features in Osceola County and adjacent areas, Florida
G.H. Hughes, James M. Frazee Jr.
1979, Open-File Report 79-1289
The western two-thirds of Osceola County, Fla., drains southward by way of the Kissimmee River and its tributaries; the eastern one-third drains eastward to the St. Johns River or to marshy areas that make up part of the headwaters of the St. Johns River. About 15 percent of the county...
Geologic map of the Cebrenia quadrangle of Mars
W. E. Elston
1979, IMAP 1140
Most of the Cebrenia quadrangle (lat 30˚ to 65˚ N., long 180˚ to 240˚ W.) is in the circumpolar plains of Mars. Craters from an early episode of intense bombardment have been largely obliterated by later volcanism, tectonism, erosion, and sedimentation by wind and water, and by circumpolar glacial...
Water resources data for New Mexico, water year 1978
Water Resources Division, U.S. Geological Survey
1979, Water Data Report NM-78-1
Water resources data for the 1978 water year for New Mexico consist of records of discharge and water quality of streams; stage, contents and water quality of lakes and reservoirs; and water levels and water quality in wells and springs. This report contains discharge records for 229 gaging stations; stage...
Hydrologic data for urban studies in the Houston, Texas, metropolitan area, 1977
James S. Hutchison
1979, Open-File Report 79-1294
Hydrologic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. Studies are now in progress in Austin, Dallas and Dallas County, Fort Worth, Houston, and San Antonio.The U.S. Geological Survey, in cooperation with the city of Houston, began studies in the Houston metropolitan area...
Data compilation of periphyton colonized on artificial substrates placed in the Sacramento and Feather rivers, California, 1975
Linda J. Britton, Rodger F. Ferreira
1979, Open-File Report 79-696
Periphyton was collected from artificial substrates placed in the Sacramento and Feather rivers, California, and analyzed to determine the rate of colonization and succession of periphyton types with time. Samples for determination of water-quality characteristics, especially suspended-sediment concentrations, that might have a direct effect on the growth of periphyton were...
