Simulated effects of proposed reservoir-development alternatives on streamflow quantity in the White River, Colorado and Utah
Gerhard Kuhn, S. R. Ellis
1984, Water-Resources Investigations Report 84-4297
Numerous reservoirs have been proposed for the White River basin in Colorado and Utah, primarily to provide water for oil-shale development. A multireservoir-flow model was used to simulate the effects of streamflow withdrawal at four of the proposed reservoirs using historical streamflow data from the 1932-81 water years. The proposed...
Identification and tabulation of geological contacts in the Edwards aquifer, San Antonio area, Texas
Ted A. Small
1984, Open-File Report 84-75
Geological contacts were picked on logs of about 480 wells in the San Antonio area of the Edwards aquifer. The base of the Del Rio Clay is the most frequently picked contact because it is the top of the Edwards aquifer and also because it is easily identified on either...

The thrust belt in Southwest Montana and east-central Idaho
Edward T. Ruppel, David A. Lopez
1984, Professional Paper 1278
The leading edge of the Cordilleran fold and thrust in southwest Montana appears to be a continuation of the edge of the Wyoming thrust belt, projected northward beneath the Snake River Plain. Trces of the thrust faults that form the leading edge of the thrust belts are mostly concealed, but...

Statistical relations among earthquake magnitude, surface rupture length, and surface fault displacement
M. G. Bonilla, R. K. Mark, J. J. Lienkaemper
1984, Open-File Report 84-256
In order to refine correlations of surface-wave magnitude, fault rupture length at the ground surface, and fault displacement at the surface by including the uncertainties in these variables, the existing data were critically reviewed and a new data base was compiled. Earthquake magnitudes were redetermined as necessary to make them...

Generalized skew coefficient for flood frequency computations for the State of Hawaii
Reuben Lee
1984, Water-Resources Investigations Report 84-4027
In 1976, the Hydrology Committee of the U.S. Water Resources Council estimated a generalized skew coefficient for flood frequency computations of -0.05 for the State of Hawaii. This value is the average of 30 stream gaging stations with 25 or more years of record through water year 1973. This report...
Predictive simulation of alternatives for managing the water resources of North Fork Solomon River Valley between Kirwin Dam and Waconda Lake, north-central Kansas
R.D. Burnett
1984, Water-Resources Investigations Report 84-4249
Since 1974 water levels in the alluvial aquifer of the North Fork Solomon River Valley in north-central Kansas have decreased due to increases in ground-water pumpage, decreases in availability of surface water for irrigation, and below-average precipitation. A finite-element model was developed in cooperation with the U.S. Bureau of Reclamation...

Hydrologic data for the Larimer-Weld regional water-monitoring program, Colorado, 1975-82
S. R. Blakely, J.T. Steinheimer
1984, Open-File Report 84-139
The Larimer-Weld, Colorado, regional Monitoring Program was begun in 1976 to provide information on the quality and quantity of the surface-water resources in the area. Three stations on the big Thompson River and five stations on the Cache La Poudre River were selected for a data-collection network. Four previously established...
Igneous activity and related ore deposits in the western and southern Tushar Mountains, Marysvale volcanic field, west-central Utah
Thomas A. Steven, editor(s)
1984, Professional Paper 1299-A,B
PART A: Igneous activity in the Marysvale volcanic field of western Utah can be separated into many episodes of extrusion, intrusion, and hydrothermal activity. The rocks of the western Tushar Mountains, near the western part of the volcanic field, include intermediate-composition, calc-alkalic volcanic rocks erupted from scattered volcanoes in Oligocene...
Directory of member organizations of the National Water Data Exchange (NAWDEX)

The National Water Data Exchange (NAWDEX) is a national confederation of water-oriented organizations working together to improve access to water data. It consists of member organizations from all sectors of the water-data community. This Directory provides the names, addresses, and telephone numbers of all NAWDEX member organizations and their designated...

Glastonbury Gneiss and mantling rocks (a modified Oliverian dome) in south-central Massachusetts and north-central Connecticut: Geochemistry, petrogenesis, and isotopic age
G. W. Leo, R. E. Zartman, D. G. Brookins
1984, Professional Paper 1295
The Glastonbury dome is a long, narrow structure trending approximately 70 km north-northeast through Connecticut and Massachusetts along the west side of the Bronson Hill anticlinorium. Structurally and stratigraphically the dome is analogous to the Oliverian domes of New Hampshire. It is cored by Glastonbury Gneiss and is mantled by...
Atmospheric deposition of selected chemicals and their effect on nonpoint-source pollution in the Twin Cities Metropolitan Area, Minnesota

1984, Water-Resources Investigations Report 83-4195
Atmospheric deposition and subsequent runoff concentrations of total Kjeldahl nitrogen, dissolved nitrite-plus-nitrate nitrogen, total phosphorus, total sulfate (only for atmospheric deposition), total chloride, and total lead were studied from April 1 to October 31, 1980, in one rural and three urban watersheds in the Twin Cities Metropolitan Area, Minnesota. Seasonal...

J.P. Marchand, R.D. Jarrett, L.L. Jones
1984, Open-File Report 84-733
Existing methods for determining the mean velocity in a vertical sampling section do not address the conditions present in high-gradient, shallow-depth streams common to mountainous regions such as Colorado. The report presents velocity-profile data that were collected for 11 streamflow-gaging stations in Colorado using both a standard Price type AA...
