Water supply and management concepts
Luna Bergere Leopold
1965, Industrial Water Engineering (2) 10-22
If I had to cite one fact about water in the United States which would be not only the most important but also the most informative, the one I would choose would k this: Over 50 percent of all the water presently being used in the United States is used...
Field application methods for recovery of the selective lampricide, 3-trifluoromethyl-4-nitrophenol
Thomas J. Billy, Stacy L. Daniels, Lloyd L. Kempe, Alfred M. Beeton
1965, Conference Paper, Proceedings of the 8th Conference on Great Lakes Research
Colorimetric methods are described for the detection of residues of the selective lampricide, 3-trifluoromethyl-4-nitrophenol (TFM), in natural waters and fish tissues. Solvent extraction and anion exchange were used to separate and concentrate the lampricide, and to reduce high background colors which often interfere with the determinations. Data from the Pentwater...
Movements of hatchery-reared lake trout in Lake Superior
Richard L. Pycha, William R. Dryer, George R. King
1965, Journal of the Fisheries Research Board of Canada (22) 999-1024
The history of stocking of lake trout (Salvelinus namaycush) in the Great Lakes is reviewed. The study of movements is based on capture of 24,275 fin-clipped lake trout taken in experimental gill nets and trawls and commercial gill nets. Yearling lake trout planted from shore dispersed to 15-fath (27-m) depths...
Age, growth, maturity, and fecundity of 'humper' lake trout, Isle Royale, Lake Superior
Jerold F. Rahrer
1965, Transactions of the American Fisheries Society (94) 75-83
Humper lake trout are one of the several races or subpopulations of lake trout in Lake Superior. This study is based on 3,705 fish collected on a reef south of Isle Royale near the eastern end. The mean lengths of humper trout from commercial gill nets were smaller than those...
Fat content of the flesh of siscowets and lake trout from Lake Superior
Paul H. Eschmeyer, Arthur M. Phillips Jr.
1965, Transactions of the American Fisheries Society (94) 62-74
Samples of flesh were excised from the middorsal region of 67 siscowets (Salvelinus namaycush siscowet) and 46 lake trout (Salvelinus n. namaycush) collected from Lake Superior. Chemical analysis of the samples revealed a range in fat content (dry weight) of 32.5 to 88.8 per cent in siscowets and 6.6 to...
Some diseases and parasites of captive woodcocks
L. N. Locke, William H. Stickel, S.A. Geis
1965, Journal of Wildlife Management (29) 156-161
Observations were made concerning the diseases and parasites of a group of woodcocks (Philohela minor) caught in Massachusetts in the summer of 1960 and kept in captivity in Maryland, and of another group caught and kept in Louisiana in the winter of 1960-61. Bumblefoot, a granulomatous swelling of the foot...
Distribution of fishes in U. S. streams tributary to Lake Superior
Harry H. Moore, Robert A. Braem
1965, Special Scientific Report - Fisheries 516
Experimental sea lamprey control by the Bureau of Commercial Fisheries on Lake Superior streams provided many new distributional records of the fish fauna. Seventy-one species were recorded from 175 streams. Specimens were collected at the electromechanical barriers, with electric shockers, with fyke nets, and during chemical treatment of streams. Maps...
A method for estimating fall adult sex ratios from production and survival data
Howard M. Wight, Robert G. Heath, A. D. Geis
1965, Journal of Wildlife Management (29) 185-192
This paper presents a method of utilizing data relating to the production and survival of a bird population to estimate a basic fall adult sex ratio. This basic adult sex ratio is an average value derived from average production and survival rates. It is an estimate of the average sex...
Two new species of Plistophoroa (Microsporidea) from North American fish with a synopsis of Microsporidea of freshwater and euryhaline fishes
R.E. Putz, G. L. Hoffman, C. E. Dunbar
1965, Journal of Protozoology (12) 228-236
Two new species of Microsporidea, Plistophora salmonae from steelhead and rainbow trout (Salmo gairdntri) and Plistophora crpedianar from gizzard shad (Dorosoma cepedianum) are described. Schizonts to spores of P. cepedianae were found at one time within the same cyst, while only sporonts and spores of P. salmonae were found within the cyst.An illustrated synopsis of the known Microsporidea of freshwater and...
Natural recharge and localization of fresh ground water in Kuwait
R.E. Bergstrom, R.E. Aten
1965, Journal of Hydrology (2) 213-231
Fresh ground water (200 parts per million total dissolved solids and upwards) occurs in portions of Pleistocene sandstone aquifers beneath basins and wadis in north Kuwait where the mean rainfall is about five inches per year. The fresh water is surrounded and underlain by brackish water (> 4000 ppm TDS)....
Glass electrode determination of sodium in closed basin waters
A.H. Truesdell, B.F. Jones, A. S. Van Denburgh
1965, Geochimica et Cosmochimica Acta (29) 725-736
Because of its direct relation to total dissolved solids content, sodium concentration is the most useful single hydrochemical parameter of closed basin waters in the western United States. Therefore, it is advantageous to have a rapid method for sodium determination which could be...
Alkali content of alpine ultramafic rocks
W. Hamilton, W. Mountjoy
1965, Geochimica et Cosmochimica Acta (29) 661-671
The lower limit of abundance of sodium and potassium in ultramafic rocks is less than the threshold amount detectable by conventional analytical methods. By a dilutionaddition modification of the flame-spectrophotometric method, sodium and potassium have been determined in 40 specimens of alpine ultramafic...
Variational method of determining effective moduli of polycrystals: (A) hexagonal symmetry, (B) trigonal symmetry
L. Peselnick, R. Meister
1965, Journal of Applied Physics (36) 2879-2884
Variational principles of anisotropic elasticity have been applied to aggregates of randomly oriented pure‐phase polycrystals having hexagonal symmetry and trigonal symmetry. The bounds of the effective elastic moduli obtained in this way show a considerable improvement over the bounds obtained by means of the Voigt and Reuss assumptions. The Hill average is found to be in...

Hydrology of the Little Plover River basin, Portage County, Wisconsin, and the effects of water resource development
Edwin P. Weeks, Donald W. Erickson, Charles Lee Roy Holt Jr.
1965, Water Supply Paper 1811
The Little Plover River basin is in the sand-plain area of central Wisconsin. The basin and the surrounding sand-plain area provide a good fish and wildlife habitat and is a popular locale for sport fishing. Good yields may be obtained in the area from irrigated crops, and the irrigated acreage...
