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...
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...
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...
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...
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...
Environmental changes in Lake Erie
Alfred M. Beeton
1961, Transactions of the American Fisheries Society (90) 153-159
Comparison of data compiled during the past 60 years with those from recent studies shows that major changes have occurred in the bottom and fish faunas of Lake Erie. The bottom fauna was formerly dominated by the nymphs of Hexagenia, but at present midge larvae and oligochaetes are most abundant....
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...
Aqua de Ney, California, a spring of unique chemical character
J. H. Feth, S. M. Rogers, C. E. Roberson
1961, Geochimica et Cosmochimica Acta (22) 75-86
The chemistry of water of Aqua de Ney, a cold spring of unusual character located in Siskiyou County, Calif., has been re-examined as part of a study of the relation of water chemistry to rock environment. The water has a pH of 11·6 and a silica content of 4000 parts...
The identification and separation of Aeromonas liquefaciens from Pseudomonas fluorescens and related organisms occurring in diseased fish
G. L. Bullock
1961, Applied Microbiology (9) 587-590
Taxonomy of the motile species of the genus Aeromonas is briefly discussed. It is suggested that Aeromonas organisms, isolated from outbreaks of red mouth of trout, red sore of pike, infectious abdominal dropsy and hemorrhagic septicemia of warm water fish, and which show acid and gas in glucose broth, production of 2,3-butanediol hydrogen sulfide...
