E. J. McKay, Joseph R. Hatch, Edwin R. Landis
1976, Open-File Report 76-387
The Knoblock coal bed in the Otter Creek EMRIA (Energy Minerals Rehabilitation Inventory and Analysis) site--an area of about 1,177 acres (476 hectares)--contains estimated identified coal resources of about 126 million short tons (114 million metric tons). The area around and including the Otter Creek EMRIA slte--an area of about...

Analytical precision of one-sixth order semiquantitative spectrographic analysis
J. M. Motooka, D. J. Grimes
1976, Circular 738
Over 2,700 separate analyses were made on 22 different geologic samples selected to cover wide concentration ranges for the 30 elements studied. The precision for low, medium, and high concentrations of each element determined is represented by superimposed frequency diagrams and displays the frequency of reported values occurring within one-sixth...
Selection of streamflow and reservoir-release models for river-quality assessment
Marshall E. Jennings, James O. Shearman, Daniel P. Bauer
1976, Circular 715-E
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
Reservoir-system model for the Willamette River basin, Oregon
James O. Shearman
1976, Circular 715-H
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
The Guatemalan earthquake of February 4, 1976, a preliminary report
A. F. Espinosa, editor(s)
1976, Professional Paper 1002
The Guatemalan earthquake of February 4, 1976, with a surface-wave magnitude of 7.5, was generated by left-lateral slippage on the Motagua fault and was felt over an area of at least 100,000 km2. This earthquake claimed more than 22,700 lives and injured more than 76,000 people. The preliminary estimate of...
Flood-prone areas of Jacksonville, Duval County, Florida
Richard B. Stone, Lawson V. Causey, D.F. Tucker
1976, Water-Resources Investigations Report 76-54
Floods in the consolidated city of Jacksonville, Duval County, Florida, are caused directly by rainfall which, when combined with storm driven tides, causes rivers or other bodies of water to flood the low lying parts of the county. This map report supplies information on areas subject to floods of 100-year...
Ground-water levels in Wyoming, 1975
Wilbur C. Ballance, Pamela B. Freudenthal
1976, Open-File Report 76-598
Ground-water levels are measured periodically in a network of about 260 observation wells in Wyoming to record changes in ground-water storage. The areas of water-level observation are mostly where ground water is used in large quantities for irrigation or municipal purposes. This report contains maps showing location of observation wells...
