Effects of grazing on runoff and sediment yield from desert rangeland at Badger Wash in western Colorado, 1953-73
Gregg C. Lusby
1978, Open-File Report 78-165
Four different systems of livestock management were compared hydrologically during a 20-year study (November 1953-November 1973) in western Colorado. These systems were grazing by cattle and sheep from November 15 to May 15 each year, complete elimination of grazing, grazing by sheep from November 15 to February 15 each year,...
Distribution of organic carbon and petroleum source rock potential of Cretaceous and lower Tertiary carbonates, south Florida basin: Preliminary results
James George Palacas
1978, Open-File Report 78-140
Analyses of 134 core samples from the South Florida Basin show that the carbonates of Comanchean age are relatively richer in average organic carbon (0.41 percent) than those of Coahuilan age (0.28 percent), Gulfian age (0.18 percent) and Paleocene age (0.20 percent). They are also nearly twice as rich as...
Geologic interpretation of gravity data from the Date Creek basin and adjacent areas, west-central Arizona
James K. Otton, Jeffrey C. Wynn
1978, Open-File Report 78-845
A gravity survey of the Date Creek Basin and adjacent areas was conducted in June 1977 to provide information for the interpretation of basin geology. A comparison of facies relations in the locally uraniferous Chapin Wash Formation and the position of the Anderson mine gravity anomaly in the Date Creek...

Floods of July 19-20, 1977 in the Johnstown area, western Pennsylvania
Stan A. Brua
1978, Open-File Report 78-963
Intense rainfall on the evening of July 19 and early morning hours of July 20, 1977, resulted in moderate to record flooding throughout much of an eight-county area of southwest Pennsylvania. In a 400-square-mile area directly north and east of Johnstown, rainfall totals of 6 to 12 inches were measured...
Manganese nodule resources in the northeastern equatorial Pacific

1978, Open-File Report 78-814
Recent publication of maps at a scale of 1:1,000,000 of the northeastern equatorial Pacific region showing publicly available information on the nickel-plus-copper content of manganese nodules has made it possible to delineate the limits of the prime area between the Clarion and Clipperton fracture zones which has been the focus...

January 1978 water levels, and data related to water-level changes since 1940 or 1950, western Kansas
Marilyn E. Pabst
1978, Open-File Report 78-409
This report contains basic data on water-level measurements in observation wells in western Kansas. The measurements were made in mid-winter, mostly in January, when pumping was minimal and water levels had recovered from the effects of pumping during the previous irrigation season. This report also provides basic hydrologic data for...

Water-resources investigations of the U.S. Geological Survey in Wyoming, fiscal year 1978
F. C. Boner
1978, Open-File Report 78-239
This report contains lists of streamflow and reservoir stations, peak-flow partial-record stations, chemical-quality stations, sediment stations, and observation wells where water levels are measured in Wyoming. The locations of the basic-data sites are shown on maps. Thirty-two water-resources appraisal projects in Wyoming are also described, including many that are related...
Effects of converting sagebrush cover to grass on the hydrology of small watersheds at Boco Mountain, Colorado
Gregg C. Lusby
1978, Open-File Report 78-289
Changes in runoff and sediment yield caused by changing sagebrush cover to grass cover were studied at four small watersheds in western Colorado during a 9-year period. Measurements of runoff and sediment yield from four watersheds were made for 3 years, at which time two watersheds were plowed and seeded...

1978, Open-File Report 78-336
There are tens of thousands of people in the United States who could play an important voluntary role in reducing earthquake hazards and are probably willing to do so. Under the Earthquake Hazard Reduction Act of 1977 the Federal government is significantly increasing its effort "to reduce the risk of life and property from...
