The 1971 drought in South Florida and its effect on the hydrologic system
Manuel A. Benson, Richard Alfred Gardner
1974, Water-Resources Investigations Report 74-12
The 1971 dry season rainfall in south Florida was low enough that the public media and concerned public officials unanimously characterized the event as a severe drought.Rainfall over all of south Florida during the 1970 wet season and the 1970-71 dry season was less than 85 percent of normal, as...
Estimated permeabilities for soils in the Sacramento Valley, California
Gilbert L. Bertoldi
1974, Water-Resources Investigations Report 73-51
Analysis of engineering and hydrologic data from 15 previous soil studies, analysis of particle-size distribution, and analysis of descriptions of soil profiles show that 50 percent of the Sacramento Valley area has soils having permeabilities characterized by infiltration rates of less than 2 feet per day (0.6 meter per day)....
Flood-hazard study, 100-year stage for Baldwin Lake, San Bernardino County, California
James J. French, Mark W. Busby
1974, Water-Resources Investigations Report 74-26
Shoreline features that represent former high-water stages on Baldwin Lake are found at 10 different altitudes that range from 6,700 to 6,713 feet (2,042 to 2,046 metres). Stage frequencies were assigned to the stages, but the date of formation of the features could be determined only for the most recent...
Reconnaissance engineering geology of Sitka and vicinity, Alaska, with emphasis on evaluation of earthquake and other geologic hazards
Lynn A. Yehle
1974, Open-File Report 74-53
A program to study the engineering geology of most of the larger Alaska coastal communities and to evaluate their earthquake and other geologic hazards was started following the 1964 Alaska earthquake; this report about Sitka and vicinity is a product of that program. Field-study methods were of a reconnaissance nature,...
Review of waterpower classifications and withdrawals, Pit River basin, California
Sterling R. Osborne
1974, Open-File Report 74-64
The purpose of this report is to evaluate the existing waterpower classifications of the Geological Survey in the Pit River basin relative to the most recent water resources information and planning. A detailed description of Geological Survey classifications is given on pages 40 and 41. In a following section each...
Hard iron ore at the Cliffs Shaft Mines, Ishpeming, Michigan
Jacob Eugene Gair
1974, Open-File Report 74-227
At the Cliffs Shaft Mines, for many years the premiere hard iron ore mine of Michigan, bodies of ore typically are localized in the upper part of the Negaunee iron-formation, close beneath Goodrich Quartzite in the axial part of the Marquette synclinorium. Individual ore bodies may be as much as...
Special techniques for determining chemical properties of geothermal water
T. S. Presser, Ivan Barnes
1974, Water-Resources Investigations Report 74-22
A reliable determination of the chemical composition of geothermal fluids may require special sampling and preservation techniques. A sample collected without pretreatment is usually adequate for the analysis of sodium, potassium, and chloride. Other constituents may require further treatment or even analysis in the field, depending on the data requirements....
Water supply at Painted Canyon Overlook, Theodore Roosevelt National Memorial Park (South Unit), southwestern North Dakota
M.G. Croft
1974, Open-File Report 74-136
A 1,930-foot (588-metre) water-supply well was constructed at the Painted Canyon Overlook, Theodore Roosevelt National Memorial Park (South Unit), southwestern North Dakota. Aquifers underlying the site are in rocks of Late Cretaceous and Tertiary age. These rocks have an aggreqate thickness of about 2,000 feet (610 metres). The well screen...
Limnological study of Lake Shastina, Siskiyou County, California
Alex E. Dong, Kenneth W. Beatty, Robert C. Averett
1974, Water-Resources Investigations Report 74-19
Lake Shastina provides water for irrigation in Shasta Valley, as well as recreation. Presently, its shoreline is being developed for summer homes. Surface water constituted more than 90 percent of the approximately 50,000 acre-foot (62-cubic hectometre) inflow to Lake Shastina in the 1972 water year. Controlled outflow is via the...
