1955, Journal of Forestry (53) 630-635
Although the Cooperative Wildlife Research Unit Program is nationwide in scope and has been in existence since 1935, it is probable that many readers of the Journal of Forestry are unaquainted with the program's objectives and accomplishments. This paper was written at the suggestion of a S.A.F. member to provide...

1955, Water Supply Bulletin 4
Webster County, comprising an area of 718 square miles just northwest of the center of Iowa, had a population of 44,241 in 1950, with 25,115 in Fort Dodge, the principal city. Some 94.4 percent of the county is in farm land; corn is the principal crop and is used in...
An electrical device for computing theoretical draw-downs of ground-water levels
Irwin Remson, M.H. Halstead
1955, Open-File Report 55-149
The construction, calibration and use of an electrical "slide rule" for computing theoretical drawdowns of ground-water levels are described. The instrument facilitates the computation of drawdowns under given conditions of discharge or recharge by means of the Theis nonequilibrium equation. It is simple to construct and use and can be...
Flood control problems
Luna Bergere Leopold, Thomas Maddock Jr.
1955, Journal of Soil and Water Conservation in India (3) 169-173
Throughout the world, alluvial soils are among the most fertile and easiest cultivated. Alluvial valleys are routes for transportation either by water or by road and railroad. Rivers are sources of water, a necessity of life. But these river valleys and alluvial deposits, which have so many desirable characteristics and...
Sediment investigations of the Platte River near Overton, Nebraska
C.D. Albert, H.P. Guy
1955, Report
This report contains results of sediment-transport investigations on the Platte River near Overton,. Nebr. from January 1950 to September 1953. The basic data of suspended-sediment studies, results of bed-material analyses, and determinations of water-surface slopes from staff readings are given. The data indicate that a reliable determination of suspended sediment, hence...

Infectious diseases of Pacific salmon
Robert R. Rucker, B. J. Earp, E. J. Ordal
1954, Transactions of the American Fisheries Society (83) 297-312
Investigations on infectious diseases of Pacific salmon due to micro-organisms other than viruses are reviewed. The etiological agents include trematodes, fungi, protozoa and bacteria. Bacteria have been found to be the most important agents of disease in the several species of Pacific salmon. Kidney disease, due to a small, unnamed...
Virus diseases of fish
Stanley W. Watson
1954, Transactions of the American Fisheries Society (83) 331-341
Viruses are probably the cause of a wide spectrum of fish diseases. Although relatively few virus diseases of fish are known today, some of the diseases of unknown etiology, as well as some diseases presently accepted as due to bacteria, protozoa, fungi or nutritional deficiencies, possibly will be recognized eventually...
A virus disease of sockeye salmon: Interim report
S.W. Watson, R.W. Guenther, R.R. Rucker
1954, Special Scientific Report - Fisheries 138
Since 1951 a disease, usually occurring in late spring or early summer, has caused severe losses in 3- to 12-month-old fingerling sockeye salmon in hatcheries in the State of Washington.
