Radio-tracer techniques for the study of flow in saturated porous materials
H.E. Skibitzke, H. T. Chapman, G.M. Robinson, Richard A. McCullough
1961, International Journal of Applied Radiation and Isotopes (10) 38-42
An experiment was conducted by the U.S. Geological Survey to determine the feasibility of using a radioactive substance as a tracer in the study of microscopic flow in a saturated porous solid. A radioactive tracer was chosen in preference to dye or other chemical in order to eliminate effects of...
Hydrology of the upper Cheyenne River basin: Part A. Hydrology of stock-water reservoirs in upper Cheyenne River basin; Part B. Sediment sources and drainage-basin characteristics in upper Cheyenne River basin
R. C. Culler, R. F. Hadley, S. A. Schumm
1961, Water Supply Paper 1531
The objective of this investigation was to determine the effect on runoff of the many stock reservoirs in the Cheyenne River basin above Angostura Dam. As a first step it was necessary to determine, within reasonable limits of accuracy, the number of reservoirs in the basin, the storage capacity, the...
Mineralogy and geochemistry of vanadium in the Colorado Plateau
A. D. Weeks
1961, Journal of the Less-Common Metals (3) 443-450
The chief domestic source of vanadium is uraniferous sandstone in the Colorado Plateau. Vanadium is 3-, 4-, or 5-valent in nature and, as oxides or combined with other elements, it forms more than 40 minerals in the Plateau ores. These ores have been studied with regard to the relative amounts...
Use of 3-trifluormethyl-4-nitrophenol as a selective sea lamprey larvicide
Vernon C. Applegate, John H. Howell, James W. Moffett, B. G. H. Johnson, Manning A. Smith
1961, Technical Report 1
The recent discovery of a group of chemical compounds that are significantly more toxic to sea lampreys than to other aquatic organisms offers promise of an early and effective control of this pest. The sea lamprey has all but destroyed the lake trout populations of Lakes Huron and Michigan. In...
A back-pack shocker for collecting lamprey ammocoetes
Robert A. Braem, Wesley J. Ebel
1961, Progressive Fish-Culturist (23) 87-91
IN 1958, THE BUREAU OF COMMERCIAL FISHERIES began to use specific larvicides for sea lamprey control in streams tributary to the Great Lakes. The successful application of larvicides required treatment of all areas of the streams infested by sea lamprey ammocoetes. Intensive surveys were needed to determine distribution of the...
Records and water-level measurements of selected wells and chemical analysis of ground water, East Shore area, Davis, Weber, and Box Elder Counties
Ralph E. Smith
1961, Utah Basic-Data Report 1
This report is intended to serve two purposes: (1) to make available to the public basic ground-water data useful in planning and studying development of water resources and (2) to supplement an interpretive report that will be published later.Records were collected during the period 1935-61 by the U.S. Geological Survey...
Hydraulic and hydrologic aspects of flood-plain planning
S.W. Wiitala, K.R. Jetter, Alan J. Sommerville
1961, Water Supply Paper 1526
The valid incentives compelling occupation of the flood plain, up to and eve n into the stream channel, undoubtedly have contributed greatly to the development of the country. But the result has been a heritage of flood disaster, suffering, and enormous costs. Flood destruction awakened a consciousness toward reduction and...
Graphic and algebraic solutions of the discordant lead-uranium age problem
L. R. Stieff, T. W. Stern
1961, Geochimica et Cosmochimica Acta (22) 176-199
Uranium-bearing minerals that give lead-uranium and lead—lead ages that are essentially in agreement, i.e. concordant, generally are considered to have had a relatively simple geologic history and to have been unaltered since their deposition. The concordant ages obtained on such materials are, therefore, assumed to approach closely the actual age...
Floods in the Skagit River basin, Washington
James E. Stewart, George Lawrence Bodhaine
1961, Water Supply Paper 1527
According to Indian tradition, floods of unusually great magnitude harassed the Skagit River basin about 1815 and 1856. The heights of these floods were not recorded at the time; so they are called historical floods. Since the arrival of white men about 1863, a number of large and damaging floods...
The trout fishery in Shenandoah National Park
Robert E. Lennon
1961, Special Scientific Report - Fisheries 395
Populations of brook trout in streams of Shenandoah National Park were reduced drastically early in the past decade by a succession of unusually severe droughts and floods. The drying of stream beds, predation, and scouring were principal factors in the loss of fish. The park was closed to fishing in...
Records, ages, and growth of the mooneye, Hiodon tergisus, of the Great Lakes
John Van Oosten
1961, Transactions of the American Fisheries Society (90) 170-174
Mooneyes (Hiodon tergisus) are very scarce in the upper three Great Lakes since only four specimens have been received from Lake Michigan, one from Lake Huron, and none from Lake Superior. The published statistics of the mooneyes are erroneous. Those of 1931 of Lake Michigan were perhaps chubs (Coregonus spp.)...
Geology and ground-water resources of Clayton County, Iowa
W. L. Steinhilber, O. J. Van Eck, A.J. Feulner
1961, Water Supply Bulletin 7
Clayton County includes 784 square miles in northeastern Iowa and in 1960 had a population of 21, 962.  For the most part, the county is a dissected upland that is drained mainly by the southeastward flowing Turkey River and its principal tributary, the Volga River.  The Turkey River empties into...
