Water-resources appraisal of the Lake Traverse Indian Reservation in South Dakota
S.J. Lawrence
1989, Water-Resources Investigations Report 88-4031
The water resources within the Lake Traverse Indian Reservation consist of streams, lakes, wetlands, and groundwater stored in alluvium and glacial outwash deposits. Streamflow may cease during dry periods and during the winter. Lakes and ponds within the reservation are found predominantly within an internally drained basin. Dissolved-solids concentrations in...
Simulation of ground-water flow at Anchorage, Alaska, 1955-83
Leslie Patrick, T. P. Brabets, R. L. Glass
1989, Water-Resources Investigations Report 88-4139
The groundwater system at Anchorage, Alaska was analyzed by using a two-layer three-dimensional mathematical model. By use of existing data, both nonpumping and pumping steady-state conditions and transient conditions were simulated. Under steady-state conditions, calculated directions of groundwater flow were similar to observed flow patterns, and calculated stream discharges generally...
A Computerized Data-Base System for Land-Use and Land-Cover Data Collected at Ground-Water Sampling Sites in the Pilot National Water Quality Assessment Program
Jonathon C. Scott
1989, Water-Resources Investigations Report 89-4172
Data-base software has been developed for the management of land-use and land-cover data collected by the U.S. Geological Survey as part of a pilot program to test and refine concepts for a National Water-Quality Assessment Program. This report describes the purpose, use, and design of the land-use and land-cover data-base...
Peak-flow characteristics of small urban drainages along the Wasatch Front, Utah
K.L. Lindskov, K. R. Thompson
1989, Water-Resources Investigations Report 89-4095
Designers and planners for local, State, and Federal agencies need up-to- date methods for determining peak-flow characteristics for urban drainages along the Wasatch Front, Utah. This report summarizes methods used to develop equations that estimate peak-flows for small urban drainages along the Wasatch Front. Mathematical equations were developed that estimate...
National assessment of undiscovered conventional oil and gas resources, USGS-MMS working paper
Water Resources Division, U.S. Geological Survey, Minerals Management Service
1989, Open-File Report 88-373
In 1981, the U.S. Geological Survey (USGS) published the results of a 1980 national assessment of undiscovered oil and natural gas resources for the United States, including the Outer Continental Shelf (OCS). The publication, USGS Circular 860, was entitled "Estimates of Undiscovered Recoverable Conventional Resources of Oil and Gas in...
Stability of nitrate-ion concentrations in simulated deposition samples used for quality-assurance activities by the U.S. Geological Survey
T. C. Willoughby, R.B. See, L.J. Schroder
1989, Water-Resources Investigations Report 89-4042
Three experiments were conducted to determine the stability of nitrate-ion concentrations in simulated deposition samples. In the four experiment-A solutions, nitric acid provided nitrate-ion concentrations ranging from 0.6 to 10.0 mg/L and that had pH values ranging from 3.8 to 5.0. In the five experiment-B solutions, sodium nitrate provided nitrate-ion...
Selected water-quality characteristics and flow of ground water in the San Luis basin, including the Conejos River subbasin, Colorado and New Mexico
R.S. Williams Jr., S.E. Hammond
1989, Water-Resources Investigations Report 89-4040
Chemical analyses of water from 99 wells and 19 springs in the San Luis basin in Colorado and New Mexico were evaluated to determine selected water quality characteristics as an aid in understanding the flow of groundwater in the basin. The evaluation shows that the distribution of chemical water types...
Descriptive statistics and spatial distributions of geochemical variables associated with manganese oxide-rich phases in the northern Pacific
Joseph Moses Botbol, Gerald Ian Evenden
1989, Bulletin 1863
Tables, graphs, and maps are used to portray the frequency characteristics and spatial distribution of manganese oxide-rich phase geochemical data, to characterize the northern Pacific in terms of publicly available nodule geochemical data, and to develop data portrayal methods that will facilitate data analysis. Source data are a subset of...
Mineral resources of the Mount Tipton Wilderness Study Area, Mohave County, Arizona
Robert C. Greene, Robert L. Turner, Robert C. Jachens, William A. Lawson, Carl L. Almquist
1989, Bulletin 1737-B
The Mount Tipton Wilderness Study Area (AZ-020-012/ 042) comprises 33,950 acres in Mohave County, Ariz. At the request of the U.S. Bureau of Land Management, this area was evaluated for identified mineral resources (known) and mineral resource potential (undiscovered). This work was carried out by the U.S. Bureau of Mines...
