Map showing thickness of material overlying principal clay unit, Hartford South quadrangle, Connecticut
William H. Langer
1974, Miscellaneous Field Studies Map 487-C
This map shows the distribution and thickness of material overlying the principal clay unit. The clay unit consists of a thick, massive bed of relatively pure clay in some areas; in other areas it consists of discrete layers of clay alternating with layers of silt and very fine sand (varved...

Summary appraisals of the nation's ground-water resources – Upper Colorado region
Don Price, Ted Arnow
1974, Professional Paper 813-C
The Upper Colorado Region covers about 113,500 square miles (293,965 km2) in parts of Arizona, Colorado, New Mexico, Utah, and Wyoming. Drainage from about 97 percent of the region is to the Colorado River. About 60 percent of the land is owned or administered by the Federal Government, and another...
Evaluation of trawls for monitoring and harvesting fish populations in Lake Oahe, South Dakota
William R. Nelson, Marvin S. Boussu
1974, Technical Paper 76
Trawls of various designs and sizes were compared to evaluate their use for monitoring and harvesting fish populations in Lake Oahe. Catches of a 10.7-m semiballoon trawl, selected to monitor changes in the fish populations from 1965 to 1970, showed a downward trend in the abundance of all species, except...

Movement and effects of spilled oil over the outer continental shelf; inadequacy of existent data for the Baltimore Canyon Trough area
Harley J. Knebel
1974, Circular 702
A deductive approach to the problem of determining the movement and effects of spilled oil over the Outer Continental Shelf requires that the potential paths of oil be determined first, in order that critical subareas may be defined for later studies. The paths of spilled oil, in turn, depend primarily...
Molybdenite in the Montezuma District of central Colorado
George J. Neuerburg, Theodore Botinelly, John R. Watterson
1974, Circular 704
The Montezuma mining district, in the Colorado mineral belt, is defined by an assemblage of porphyry, ore, and altered rocks that originated in the venting of a Tertiary batholith through weak structures in Precambrian rocks. The ore consists of silver-lead-zinc veins clustered on the propylitic fringe of a geometrically complex...
Selenium, fluorine, and arsenic in surficial materials of the conterminous United States
Hansford T. Shacklette, Josephine G. Boerngen, John R. Keith
1974, Circular 692
Concentrations of selenium, fluorine, and arsenic in 912, 911, and 910 samples, respectively, of soils and other regoliths from sites approximately 50 miles (80 km) apart throughout the United States are represented on maps by symbols showing five ranges of values. Histograms of the concentrations of these elements are also...
Model synthesis in frequency analysis of Missouri floods
Leland D. Hauth
1974, Circular 708
Synthetic flood records for 43 small-stream sites aided in definition of techniques for estimating the magnitude and frequency of floods in Missouri. The long-term synthetic flood records were generated by use of a digital computer model of the rainfall-runoff process. A relatively short period of concurrent rainfall and runoff data...

The commercial fishery in Lake Oahe, North and South Dakota, 1964-70
Joseph H. Higham
1974, Technical Paper 80
Ten species were commercially harvested in Lake Oahe, among which bigmouth buffalo (Ictiobus cyprinellus) predominated (63.8% of the total weight), smallmouth buffalo (Ictiobus bubalus) and goldeye (Hiodon alosoides) ranked second, and third. Variations in the seasonal and annual production of buffalo were governed by market conditions and availability. Production of...

Low-flow characteristics of Kentucky streams - A preliminary report
R.V. Swisshelm Jr.
1974, Open-File Report 73-273
The U.S. Geological Survey has been gathering low-flow data on streams throughout Kentucky for several decades. Much of the data now have been analyzed to determine the frequency of the annual low flow on those streams. Knowledge of the magnitude and frequency of low flow is necessary for planning, managing,...
