1972, Utah Basic-Data Release 24
This report presents the basic data that were collected by the U.S. Geological Survey during a study of the chemical quality of water in Flaming Gorge Reservoir. An interpretive report will follow. The basic data were collected from the reservoir during six sampling runs between October 1970 and September 1972....
Cloudburst floods in Utah, 1939-69
Elmer Butler, Ray E. Marsell
1972, Report
During 1939-69, 836 cloudburst floods were reported in Utah. The largest number was in 1965, when 88 floods were reported; 63 floods were reported in 1968, and 56 were reported in 1961. The smallest number of floods reported was three in 1944. In 1942, 1948, and 1950, six floods were...
Duck hepatitis virus Interactions with DDT and dieldrin in adult mallards
Milton Friend, D.O. Trainer
1972, Bulletin of Environmental Contamination and Toxicology (7) 202-206
There has been considerable speculation regarding possible imteractlons within biological systems between synthetic environmental pollutants and infectious disease agents (1-11). This type of interaction has been studied in our laboratory using the mallard, Anas platyrhynchos, as a test species (5,6). Since adult ducks are refractory to the overt manifestations of...
Some physiological consequences of handling stress in the juvenile coho salmon (Oncorhynchus kisutch) and steelhead trout (Salmo gairdneri)
Gary Wedemeyer
1972, Journal of the Fisheries Research Board of Canada (29) 1780-1783
The stress of handling juvenile coho salmon (Oncorhynchus kisutch) and steelhead trout (Salmo gairdneri) in soft water and in water with added salts was evaluated using blood and tissue chemistry fluctuations as indices of metabolic and endocrine function. Changes in plasma glucose, chloride, calcium, and cholesterol levels indicated that significant...
Virucidal activity of two Iodophors to salmonid viruses
Donald F. Amend, John P. Pietsch
1972, Journal of the Fisheries Research Board of Canada (29) 61-65
Wescodyne® and Betadine®, organic iodine complexes, were compared in vitro for virucidal activity against infectious hematopoietic necrosis (IHN), infectious pancreatic necrosis (IPN), and viral hemorrhagic septicemia (VHS) viruses. Both iodophors were about equally effective on all three viruses. Each iodophor completely destroyed IHN virus within 30 sec at 12 ppm iodine, and was...
Hydraulic tests in hole UAe-6h, Amchitka Island, Alaska
Wilbur C. Ballance
1972, Report
Inflatable straddle packers were used to isolate and test 14 intervals ranging from 39 to 258 meters (127 to 846 feet) each in hole UAe-6h. Packer seats were poor in part of the hole because of unstable wall conditions. Thus, some zones had to be tested several times. The static...
Water inflow into hole UA-1, Amchitka Island, Alaska
Wilbur C. Ballance, W.A. Beetem
1972, Report
Chemical composition of water samples, temperature of inflow water, and theoretical calculations were compared to evaluate the water-contributing intervals to the zone to be mined--1,782.8 to 1,798.6 meters (5,849 to 5,901 feet)--in hole UA-1, Amchitka Island, Alaska. Chemical composition and temperature of inflow water indicated the contributing zones to have...
Some rates of geomorphological processes
Luna Bergere Leopold, William W. Emmett
1972, Geographia Polonica (23) 27-36
This brief report summarizes three sets of measurement data on certain processes.The first concerns the rate of movement of soil on hillslopes, especially by mass movement or slow gravitational creep. The results are abstracted from an unpublished manuscript by the junior author who reports on the measurements which Leopold began...

An improved method for isolating viruses from asymptomatic carrier fish
Donald F. Amend, John P. Pietsch
1972, Transactions of the American Fisheries Society (101) 267-269
This paper describes a method using elevated levels of penicillin, streptomycin, and nystatin instead of filters to control bacteria and mold contaminants in specimens processed for virus isolation. Filters were shown to significantly reduce the virus concentration. Virus and tissue cultures were not affected by this procedure. In field tests...
Location and description of spiral-shaped microorganisms in the normal rat cecum
Charles P. Davis, D. Mulcahy, A. Takeuchi, D.C. Savage
1972, Infection and Immunity (6) 184-192
Some indigenous microorganisms have been shown to localize in certain anatomical sites of the digestive tract of mammals. We studied the ceca of normal adult rats by light and electron microscopy to determine whether any specific bacterial population localizes in this area. All rats studied showed...
Survey for infectious hematopoietic necrosis (IHN) virus in Washington salmon
Donald F. Amend, James W. Wood
1972, Progressive Fish-Culturist (34) 143-147
A virus disease of juvenile sockeye salmon (Oncorhynchus nerka) has been a problem in Washington hatcheries since first reported by Rucker [9] in 1953. Presumably, the same disease has occurred in Oregon, and it is now referred to as the Oregon, and it is now referred to as the Oregon...
Sediment transport and deposition, Walnut and Pacheco Creeks, Contra Costa County, California, August 1965-April 1970
George Porterfield
1972, Open-File Report 72-302
Average annual sediment discharge in Pacheco Creek basin, Contra Costa County, Calif., was larger during August 1965-April 1970 than the historical annual sediment discharge (1909-62) by a factor of about 1.3. This increas in sediment discharge is attributed primarily to an increased frequency of peak streamflows and to a larger...

Charles E. Sloan
1972, Open-File Report 72-348
A hydrologic reconnaissance was made of Anaktuvuk pass in the central Brooks Range during the summer of 1971 to help develop a water supply for the village school. Winter icings and summer flow conditions in Contact Creek both indicate that ground water is present beneath the creek bed. A well-site...
