Precambrian basement map of the northern Midcontinent, U.S.A.
1985, Open-File Report 85-604
The northern midcontinent region includes the buried basement of the interior platform and the southernmost exposed Precambrian rocks of the Canadian Shield (see index map). Structurally, it is part of a continent-wide "tectonic collage" consisting of (1) Archean cratonic elements (>2500 Ma) and remnants of Early Proterozoic (-1,900-2,100 Ma) cratonic...
Base-flow characteristics of segments of the Piney River, and East and West Piney Rivers, Dickson and Hickman Counties, Tennessee
V.J. May
1985, Open-File Report 85-155
Base-flow profiles based on discharge measurements made during a seepage investigation on August 28, 1984, define losing and gaining reaches of segments of the Piney River, and East and West Piney Rivers, Dickson and Hickman Counties, central Tennessee. A similar profile defines losing and gaining reaches for the average 3-day...
Discharge ratings for control gates at Mississippi River Lock and Dam 14, Le Claire, Iowa
A.J. Heinitz
1985, Water-Resources Investigations Report 85-4261
The water level of the navigation pools on the Mississippi River are maintained by the operation of tainter and roller gates at the locks and dams. Discharge ratings for the gates on Lock and Dam 14, at Le Claire, Iowa, were developed from current-meter discharge measurements made in the forebays...
Preliminary study of the water-temperature regime of the North Santiam River downstream from Detroit and Big Cliff dams, Oregon
Antonius Laenen
1985, Water-Resources Investigations Report 84-4105
A riverine-temperature model and associated data-collection system were developed to help the Corps of engineers determine cost benefits of selective-withdrawal structures for future use with dams on the Willamette River System. A U.S. Geological Survey Lagrangian reference frame, digital computer model was used to simulate stream temperatures on the North...
Quality of water and bed material in streams of Logan Township, Gloucester County, New Jersey, 1984
J. J. Hochreiter, Jane Kozinski
1985, Water-Resources Investigations Report 85-4300
The surface water and surficial-bed material at seven stations on three streams in Logan Township, Gloucester County, New Jersey, were sampled in the fall of 1984. Samples of water were analyzed for volatile organic compounds, trace metals, and organochlorine and organophosphorous compounds. Surficial-bed material was analyzed for extractable trace metals...
Cost effectiveness of the stream-gaging program in Louisiana
R.A. Herbert, D.D. Carlson
1985, Water-Resources Investigations Report 85-4044
This report documents the results of a study of the cost effectiveness of the stream-gaging program in Louisiana. Data uses and funding sources were identified for the 68 continuous-record stream gages currently (1984) in operation with a budget of $408,700. Three stream gages have uses specific to a short-term study...
An evaluation of the crest-stage gage program in Louisiana
R.A. Herbert, D.D. Carlson, G.J. Wiche
1985, Water-Resources Investigations Report 84-4204
The crest-stage gage program in Louisiana was evaluated to determine if the data were adequate for use in developing regional flood-frequency equations and to determine if any crest-stage gages could be discontinued. An abundance of data at many crest-stage stations and a lack of data for urban area and flat-slope...
Survey of Fena Reservoir, Island of Guam: Limnological reconnaissance
J. W. LaBaugh
1985, Water-Resources Investigations Report 83-4241
During the limnological reconnaissance of Fena Reservoir, samples of the water columns and bottom sediment were obtained and analyzed at five locations within the reservoir. Major ion analyses of filtered surface water indicated that calcium and bicarbonate are the dominant cation and anion in the reservoir. Thermal stratification was recorded...
A preliminary assessment of land-surface subsidence in the El Paso area, Texas
L. F. Land, C. A. Armstrong
1985, Water-Resources Investigations Report 85-4155
The northeast and southeast parts of the El Paso area are underlain by Hueco bolson deposits as much as 9,000 feet thick. The deposits consist of lenses of gravel, sand, silt, and clay. In the Rio Grande Valley, about 400 to 450 feet of these deposits have been eroded and...
Cost-effectiveness of the Federal stream-gaging program in Virginia
D.H. Carpenter
1985, Water-Resources Investigations Report 85-4345
Data uses and funding sources were identified for the 77 continuous stream gages currently being operated in Virginia by the U.S. Geological Survey with a budget of $446,000. Two stream gages were identified as not being used sufficiently to warrant continuing their operation. Operation of these stations should be considered...
Contributions of suspended sediment from highway construction and other land uses to the Olentangy River, Columbus, Ohio
D.R. Helsel
1985, Water-Resources Investigations Report 84-4336
Highway construction within the Olentangy River flood plain in Columbus, Ohio, was projected to be a large source of suspended sediment to the river system. A monitoring program was begun by the U.S. Geological Survey in 1978 to quantify the implacts of construction process. Sediment information was collected daily at...
Reconnaissance of mine drainage in the coal fields of eastern Pennsylvania
D.J. Growitz, L.A. Reed, M.M. Beard
1985, Water-Resources Investigations Report 83-4274
Anthracite has been extensively mined in four areas of eastern Pennsylvania. Almost all underground mining in the four areas, the Northern, Eastern Middle, Western Middle, and Southern Fields, has been discontinued and many mines are abandoned and flooded. Precipitation on much of the 408 square miles of coal fields infiltrates...
