Preliminary description of cores, chemical analyses of lignite beds, and map showing locations of holes drilled in Grant, Hettinger, Morton, and Stark Counties, North Dakota
H.L. Smith
1970, Open-File Report 70-308
Nineteen exploratory holes were drilled in Grant, Hettinger, Morton, and Stark Counties, N. Dak. (fig. 1), for the U.S. Geological Survey from June 7 to September 15, 1966. This prospect drilling was undertaken to gather data on the thickness, quality, and extent of lignite beds and the lithologic characteristics of...
Flood frequency in Alaska
J.M. Childers
1970, Open-File Report 70-63
Records of peak discharge at 183 sites were used to study flood frequency in Alaska. The vast size of Alaska, its great ranges of physiography, and the lack of data for much of the State precluded a comprehensive analysis of all flood determinants. Peak stream discharges, where gaging-station records were...
Chemical and biological conditions in Bald Eagle Creek and prognosis of trophic characteristics of Foster Joseph Sayers Reservoir, Centre County, Pennsylvania
Herbert N. Flippo Jr.
1970, Open-File Report 71-109
Foster Joseph Sayers. Reservoir will b.e impounded on moderately fertile soils; however, its water source, Bald Eagle Creek, is a bicarbonate-water stream that is over~y-enriched with nutrients. About 650 of the 1,730 acres to be inundated in summer are subject to infestation with aquatic weeds. Nuisance algal "blooms" are expected...
A continuing program for estimating ground-water pumpage in California--Methods
William Ogilbee, Hugh T. Mitten
1970, Open-File Report 70-246
Municipal and agricultural ground-water pumpage is being estimated for the principal ground-water basins in California. Because of its anticipated use in analog or digital hydrologic models, agricultural pumpage is estimated for unit areas.Estimated municipal pumpage is based on census figures and population projections and on pumpage reported by organizations in...
Summary of ground-water hydrological data in Michigan in 1968
P.R. Giroux, G.C. Huffman
1970, Open-File Report 70-135
The purpose of this report is to make available the records of groundwater levels in the principal aquifers of the State through 1968 and to compile other related data, such as records of ground-water pumpage, data on municipal, public and industrial water-supply facilities, and the effects of precipitation on ground-water...
An appraisal of the Jabal Idsas magnetite mineralization based on diamond drill hole N40A
Conrad Martin
1970, Open-File Report 70-215
Diamond Drill Bole N40, intended to test the magnetite mineralization at Jabal Idsas, was aborted because of technical difficulties and a new hole, N4OA, was drilled at the same site in February of 1968 to an inclined down-the-hole depth of 445.7 meters. Disseminated magnetite and locally massive lenses, veins, and...
