Hydrologic reconnaissance and summary of existing data on surface and ground-water resources in the Missouri River valley in Woodbury and Monona counties, Iowa, 1985
R.C. Buchmiller
1986, Open-File Report 86-144
A hydrologic reconnaissance of the Missouri River valley in western Iowa was begun in 1985. The study area is about 400 sq mi of Missouri River flood plain used mainly for agricultural purposes and is located mostly in parts of Woodbury and Monona Counties, Iowa. The reconnaissance was conducted to...
Water-use data-collection programs and regional data base of the Great Lakes-St. Lawrence River Basin states and provinces; a comparison of withdrawal-data programs by water-use category and by state and province
D. S. Snavely
1986, Open-File Report 86-546
As a result of the Great Lakes Charter (signed by Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Ontario, Pennsylvania, Quebec, and Wisconsin), the Geological Survey worked with a committee of the Council of Great Lakes Governors to document the water use data collection programs in the Basin. These programs are...
Map of Western Copper River Basin, Alaska, Showing Lake Sediments and Shorelines, Glacial Moraines, and Location of Stratigraphic Sections and Radiocarbon-Dated Samples
John R. Williams, John P. Galloway
1986, Open-File Report 86-390
The purpose of this report is to make available basic data on radiocarbon dating of 61 organic samples from 40 locations in the western Copper River Basin and adjacent uplands and in the uppermost Matanuska River Valley. The former distribution of late Quaternary glacial lakes and of glaciers as mapped...
Altitude and configuration of the water table in the High Plains Aquifer in Kansas, 1960

1986, Open-File Report 82-429
The High Plains aquifer in Kansas is part of a regional aquifer system that extends into Colorado, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. The aquifer in Kansas underlies an area of 31,000 square miles in the western and south-central part of the State. The aquifer is a...
Geochemical maps showing distribution and abundance of manganese in two fractions of stream-sediment concentrates, Silver City 1 degree by 2 degrees Quadrangle, New Mexico and Arizona
Kenneth C. Watts, Jerry R. Hassemer, Carl L. Forn, David F. Siems
1986, Miscellaneous Field Studies Map 1183-J
These maps (Maps A and B) show the distribution and abundance of maganese in the nonmagnetic and magnetic fractions of heavy-mineral concentrates from stream sediments collected in the Silver City 1o x 2o quadrangle, New Mexico and Arizona. Geochemical maps showing the distribution and abundance of 10 other selected key elements and the mineral...
Annual summary of ground-water conditions in Arizona, spring 1984 to spring 1985
Water Resources Division, U.S. Geological Survey
1986, Open-File Report 86-422-W
In arid and semiarid regions such as Arizona, the availability of adequate water supplies has a significant influence on the type and extent of economic development. About two-thirds of the water used in the State is groundwater. The nature and extent of the groundwater reservoirs must be known for proper...
Approximate altitude of water levels in wells in the Chicot and Evangeline aquifers in the Houston area, Texas, spring 1986
James Frank Williams III, C.E. Ranzau Jr., L.S. Coplin
1986, Open-File Report 86-306
The purpose of this report, which was prepared in cooperation with the City of Houston and the Harris-Galveston Coastal Subsidence District, is to show the altitudes of water levels in wells in the Chicot and Evangeline aquifers in the Houston, Texas, metropolitan areas.  The maps are based on water-level measurements...
Ground-water levels in Alaska, water year 1983
J.O. Brunett
1986, Open-File Report 86-56
Groundwater level data in Alaska are summarized for the 1983 water year for observation wells at which levels are either recorded continuously or measured intermittently. For wells at which water levels are measured semi-annually, 10-year summaries are presented. Water levels for 153 observation wells are shown on graphs and locations...
Effects of organic wastes on water quality from processing of oil shale from the Green River Formation, Colorado, Utah, and Wyoming
J.A. Leenheer, T.I. Noyes
1986, Professional Paper 1338
A series of investigations were conducted during a 6-year research project to determine the nature and effects of organic wastes from processing of Green River Formation oil shale on water quality. Fifty percent of the organic compounds in two retort wastewaters were identified as various aromatic amines, mono- and dicarboxylic...
