Digital-simulation and projection of water-level declines in basalt aquifers of the Odessa-Lind area, east-central Washington
J. E. Luzier, James A. Skrivan
1975, Water Supply Paper 2036
A digital computer program using finite-difference techniques simulates an intensively pumped, multilayered basalt-aquifer system near Odessa. The aquifers now developed are in the upper 1,000 feet of a regionally extensive series of southwesterly dipping basalt flows of the Columbia River Group. Most of the aquifers are confined. Those in the...
Water resources of the Mississippi and Sauk Rivers Watershed, central Minnesota
John O. Helgesen, Donald W. Ericson, Gerald F. Lindholm
1975, Hydrologic Atlas 534
A variety of glacial landforms (moraines, till plains, drumlin fields and outwash plains) characterized the 3,890-square mile Mississippi and Sauk Rivers watershed. Underlying the glacial drift are Cambrian and Precambrian sedimentary rocks in the southeastern part of the watershed and Precambrian igneous and metamorphic rocks elsewhere. Surface drainage is entirely to the...
Reactions of aqueous aluminum species at mineral surfaces
David Wayne Brown, John David Hem
1975, Water Supply Paper 1827-F
Aqueous aluminum solutions containing 4.5 ? 10 4 molar aluminum in 0.01 molar NaC104 were partly neutralized with NaOH to give OH:A1 mole ratios from 1.40 to 2.76. Measured amounts of montmorillonite, kaolinite, volcanic ash, or feldspathic sand were added to provide an area of inert surface. Reactions that occurred...
Water resources of the Lake of the Woods watershed, north-central Minnesota
John O. Helgesen, Gerald F. Lindholm, Donald W. Ericson
1975, Hydrologic Atlas 544
The Lake of the Woods watershed is an area of about 2,900 square miles (7,500 km), the northern limit of which is part of the boundary between the United States and Canada. Drainage is to Lake of the Woods, either directly or by the Rainy River. The watershed includes about...
Geology of the Sierra Foothills Melange and adjacent areas, Amador County, California
Wendell A. Duffield, Robert V. Sharp
1975, Professional Paper 827
Detailed outcrop mapping in the western Sierra foothills of Amador County, Calif., has resulted in some major changes in the interpretation of stratigraphy and structure. The Amador Group was originally defined at its type locality on the south bank of the Cosumnes River in Amador County to include the Cosumnes...
Map showing availability of hydrologic data published by the U.S. Environmental Data Service and by the U.S. Geological Survey and cooperating agencies, greater Denver area, Front Range Urban Corridor, Colorado
E. R. Hampton
1975, IMAP 856-C
What is the rainfall of this region? What areas are prone to periodic flooding? What is the water supply? What is the chemical quality of the ground water and water in the streams? How deep is the water table? Which streams are gaged, and where? These and similar questions are...
