Age and growth of the lake whitefish, Coregonus clupeaformis (Mitchill), in Lake Erie
John Van Oosten, Ralph Hile
1949, Transactions of the American Fisheries Society (77) 178-249
Although the whitefish has by no means ranked first from the standpoint of production, it has always been an important commercial species in Lake Erie. Trends in the output of whitefish have differed in the United States and Canadian waters of the lake. The 1893–1946 average annual yield of 1,201,000...
Trends in the lake trout fishery of Lake Huron through 1946
Ralph Hile
1949, Transactions of the American Fisheries Society (76) 121-147
The production of lake trout, Cristivomer namaycush (Walbaum), in the United States waters of Lake Huron was highest in the earliest years for which there are statistical records, averaging 2,362,000 pounds in 1879–1894. The general level of yield was much lower but relatively stable in 1895–1939, during which period the...
Natural water losses in mountain drainage areas of southern California
Harold C. Troxell, H.M. Stafford
1949, Eos, Transactions, American Geophysical Union (30) 752-758
For twenty‐five small mountain drainage areas of Southern California, natural water losses are shown to vary with basin altitude, and with estimated absorptive and retentive characteristics of the drainage areas. Among other relationships demonstrated is the increase of the annual natural water loss with increased annual precipitation to an optimum,...
Ground water in the East Shore area, Utah. Part I. Bountiful District, Davis County
H. E. Thomas, W.B. Nelson
1948, Technical Publication 5
The Bountiful district in Davis County, Utah, less than 10 miles from the heart of Salt Lake City, is rapidly becoming an integral part of the metropolitan area of Salt Lake City. It cannot achieve the development that its location merits unless the present water supplies are increased. The district...
New compounds for the control of bacterial gill disease
R.R. Rucker
1948, Progressive Fish-Culturist (10) 19-22
BACTERIAL GILL DISEASE, a common epizootic among hatchery fish, can be controlled by copper sulphate dips, as stated by Davis (1945), or by prolonged treatments with Roccal, as noted by Fish (1947). The use of copper sulphate is not without danger because of variation in toxicity according to the hardness...
Removal of excess nitrogen in a hatchery water supply
R.R. Rucker
1948, Progressive Fish-Culturist (10) 88-90
The water system at the U. S. Fish Cultural Station, Leavenworth, Washington, has been supplemented with two wells that were to be used to increase the temperature of the water during the winter and to cool the Water in the summer if necessary. The well water proved to be unsuitable...
Ground water in the Blanchard area, McClain County, Oklahoma
Leon Virgil Davis, Stuart L. Schoff
1948, Open-File Report 48-80
A letter from Lloyd L. Bowser, City Clerk, dated January 8, 1948, in behalf of the town council and Mayor Walter Casey, indicates that a serious shortage of water is faced by the town of Blanchard, McClain County, Oklahoma. The town is near the eastern boundary of Grady County, where...
Electrical resistivity investigations at Memphis, and Bolivar, Tennessee
H. Cecil Spicer
1948, Open-File Report 48-25
This geophysical investigation was undertaken upon request of Elliott M. Cushing of the Ground Water Division Office at Memphis, Tennessee. The field work was performed during the period March 13 to 28, 1947; the apparent resistivity curves were interpreted during November and December; and the report was written subsequent to...
Water-supply investigation at Chinle, Navajo Indian Reservation, Arizona
Leonard C. Halpenny, S.C. Brown
1948, Open-File Report 48-78
In late January 1948 the Geological Survey was requested to investigate the possibilities of obtaining additional water supplies at four sites on the Navajo Indian Reservation. Each site was given a priority, and the site at Chinle was designated as second of the four in importance. Field work was to...
