Geohydrology and model analysis for water-supply management in a small area of west-central Kansas
Lloyd E. Dunlap, Jack Kume, James G. Thomas
1980, Water-Resources Investigations Report 80-91
The Ogallala Formation in the intensive-study area, an area of 12 square miles in northeastern Wichita County, west-central Kansas, has had a substantial decrease in saturated thickness since the development of irrigation. The annual water-level decline during 1950-78 ranged from 1.08 to 2.22 feet per year.The hydrologic system was investigated...

Effects of urbanization on the water quality of lakes in Eagan, Minnesota
M. A. Ayers, G. A. Payne, Mark A. Have
1980, Water-Resources Investigations Report 80-71
Water-quality characteristics of 17 lakes and ponds in the city of Eagan were described from data collected from 1972 through 1978. The data showed that differences in water quality between lakes were related to differences in the percentage of urbanization. However, water-quality variations within each lake were affected more by...
Hydrologic data for North Creek, Trinity River basin, Texas, 1978
C.C. Kidwell
1980, Open-File Report 80-573
The U.S. Soil Conservation Service is actively engaged in the installation of flood- and soil-erosion reducing structures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The U.S. Soil Conservation Service has found...
Chemical analyses of coal and coal-associated shale samples from the lower part of the Fort Union Formation, Little Snake River coal field, Sweetwater and Carbon counties, Wyoming
Joseph R. Hatch, Ronald H. Affolter
1980, Open-File Report 80-92
As part of a continuing program by the U.S. Geological Survey to collect and analyze representative samples of U.S. coals, 26 coal and 5 coal-associated shale samples were collected from 13 core and rotary-drill holes in the lower part of the Paleocene Fort Union Formation in the Little Snake River...
Ground-water hydrology of James City County, Virginia
John F. Harsh
1980, Open-File Report 80-961
Urbanization and increase in water demand prompted a 2-year study of groundwater availability and quality in the county of James City. The coastal-plain sediments, parts of which underlie the county, are the largest source of groundwater in Virginia. Four aquifers form the complex aquifer system. Hydraulic characteristics vary from aquifer...
