The deuterium blance of Lake Maracaibo
Irving Friedman, Daniel R. Norton, D.B. Carter, A.C. Redfield
1956, Limnology and Oceanography (1) 239-246
A balance sheet for the gains and losses of deuterium from Lake Maracaibo, using estimates based on climatological data for the exchanges of water and measurements of the deuterium content of lake water, rainfall, river flow, and Caribbean Sea water to obtain the volumes of the deuterium exchange, indicates that...
Geophysical studies in the intermontane basins in southern California
Don R. Mabey
1956, Geophysics (21) 839-853
Geophysical surveys were made by the U. S. Geological Survey in Searles Lake basin and in the Mojave Desert near Barstow, California to test the application of geophysical exploration to the study of the geologic problems associated with the intermontane basins of southern California. In Searles Lake basin a coordinated...
Numerical analysis of regional water levels to define aquifer hydrology
Robert W. Stallman
1956, Eos, Transactions, American Geophysical Union (37) 451-460
Two fundamental methods for studying aquifer hydrology are now in use. The first, applied many years ago, consists of detailed observation of aquifer inflow, outflow, and storage changes, and their variations in time. By analysis of these observations, estimates of the perennial recharge to the aquifer and other pertinent hydrologic...
Application of the modified Einstein procedure for computation of total sediment load
K. B. Schroeder, C. H. Hembree
1956, Eos, Transactions, American Geophysical Union (37) 197-212
A method that enables good estimates to be made of total sediment load has been tested with data from several western streams. The method, which uses both theoretical and empirical formulas, combines a modification of Einstein's procedure for computing bed‐material load and the usually available data from suspended‐sediment measurements. Basic...
Non-pegmatitic resources of beryllium in United States
Lawrence Allen Warner, W.T. Holser, V.R. Wilmarth, E.N. Cameron
1956, Trace Elements Investigations 137
During the period from 1948 to 1950 the U.S. Geological Survey conducted a program of field and laboratory research w determine the mode of occurrence of beryllium in non-pegmatitic rocks and mineral deposits as part of the Beryllium Program of the Division of Raw Materials of the U.S. Atomic Energy Commission. Approximately 23...
Some limitations on the possible composition of the ore-forming fluid
Paul B. Barton Jr.
1956, Trace Elements Investigations 633
The activity rations of various important anions (S, CO3, SO4, OH, F, and Cl) in hydrothermal solutions at the time of deposition are evaluated using a simple thermodynamic technique. The rations are interpreted in the light of the mineralogy of ore deposits and limites are placed on the variability of...
Life history of lake herring of Green Bay, Lake Michigan
Stanford H. Smith
1956, Fishery Bulletin (109) 87-138
Although the lake herring has been an important contributor to the commercial fish production of Green Bay, little has been known about it. This study is based on field observations and data from about 6,500 lake herring collected over the period 1948 to 1952. Relatively nonselective commercial pound nets...
Floods in relation to the river channel
Luna Bergere Leopold, M. Gordon Wolman
1956, Proceedings of the International Association of Hydrological Sciences 85-98
Among the rivers studied by us two broad types may be distinguished. Channels in the semi-arid areas scour at high discharges so that the bed lowers nearly as much as the water surface rises. Detailed data on the middle reaches of the Rio Grande in New Mexico during the spring...
Data and understanding
Luna Bergere Leopold
Gilbert F. White, editor(s)
1956, Conference Paper, The future of arid lands: Papers and recommendations from the International Arid Lands Meetings
In the year 1534 when Cabeza de Vaca escaped from the aborigines of southern Texas by whom he had been enslaved for six years, he made his way on foot from the vicinity of Galveston to the west coast of Mexico. Although his Relación was not printed until 1542, the...
Stratigraphic sections of the Phosphoria formation 1953 and 1954
R. W. Swanson, L.D. Carswell, R.P. Sheldon, T. M. Cheney
1955, Trace Elements Investigations 570
Since 1947, the U.S. Geological Survey has measured and sampled phosphatic parts of the Permian Phosphoria formation and its partial stratigraphic correlatives at many localities in Montana, Idaho, Wyoming, and Utah.  Preliminary data on the thickness of the beds and their composition at localities sampled prior to 1952 have been...
Geology and beryl deposits of the Peerless pegmatite, Pennington County, South Dakota
Douglas M. Sheridan, Hal G. Stephens, Mortimer H. Staatz, James J. Norton
1955, Trace Elements Investigations 226
The Peerless pegmatite, half a mile south of Keystone, Pennington County, S. Dak., has been a large source of scrap mica and beryl. Feldspar, amblygonite, tantalite-columbite, and cassiterite also have been recovered. The pegmatite is intrusive into Precambrian quartz-mica schist. Much of the schist contains staurolite and chlorite. Staurolite has been...
Coal reserves of the Pittsburgh (No. 8) bed in Belmont County, Ohio
Henry L. Berryhill
1955, Circular 363
Remaining coal reserves totaling 1,929 million tons have been appraised in the Pittsburgh (No. 8) coal bed in Belmont County, Ohio. Of these, 508 million tons are classified as measured and 1,421 million tons are classified as indicated. All the coal has less than 1,000 feet of overburden, and most...
Geology of the Calamity Mesa quadrangle, Colorado
Fred W. Cater
1955, Geologic Quadrangle 61
The series of Geologic Quadrangle Maps of the United States continues the series of quadrangle maps begun with the folios of the Geologic Atlas of the United States, which were published from 1894 to 1945. The present series consists of geologic maps, supplemented where possible by structure sections, columnar sections,...
Annual peak discharges from small drainage areas in Montana through September 1980
R. J. Omang, Charles Parrett, J. A. Hull
1955, Open-File Report 81-332
Annual peak stage and discharge data have been collected and tabulated for crest-stage gaging sites in Montana. The crest-stage program was begun in July 1955 to investigate the magnitude and frequency of floods from small drainage areas. The program has expanded from 45 crest-stage gaging stations initially to 172 stations...
Chemical quality of surface waters in Devils Lake basin, North Dakota
Herbert Swenson, Bruce R. Colby
1955, Water Supply Paper 1295
Devils Lake basin, a closed basin in northeastern North Dakota, covers about 3,900 square miles of land, the topography of which is morainal and of glacial origin. In this basin lies a chain of waterways, which begins with the Sweetwater group and extends successively through Mauvais Coulee, Devils Lake, East...
Computations of total sediment discharge, Niobrara River near Cody, Nebraska
Bruce R. Colby, C. H. Hembree
1955, Water Supply Paper 1357
A natural chute in the Niobrara River near Cody, Nebr., constricts the flow of the river except at high stages to a narrow channel in which the turbulence is sufficient to suspend nearly the total sediment discharge. Because much of the flow originates in the sandhills area of Nebraska, the...

C.F. Keech, R.L. Case
1955, Open-File Report 55-80
The observation well program, begun in 1934 in cooperation with the Conservation and Survey Division, University of Nebraska, was continued during 1954.  The United States Geological Survey began a series of ground-water investigations in Nebraska during the fall of 1945, as part of the program for development of the Missouri...
Ground-water hydraulics - A summary of lectures presented by John G. Ferris at short courses conducted by the Ground Water Branch, part 1, Theory
D.B. Knowles
1955, Open-File Report 55-85
The objective of the Ground Water Branch is to evaluate the occurrence, availability, and quality of ground water.  The science of ground-water hydrology is applied toward attaining that goal.  Although many ground-water investigations are of a qualitative nature, quantitative studies are necessarily an integral component of the complete evaluation of...
