Traveltimes along Clear Creek and selected tributaries upstream from Golden, Colorado, 1996-97
Sally M. Cuffin
1999, Water-Resources Investigations Report 98-4151
Increased traffic along mountainous stretches of Interstate Highway 70, U.S. Highway 40, and U.S. Highway 6 in Colorado has resulted in a corresponding increase in the movement of hazardous materials. The proximity of Clear Creek and its tributaries to these highways places downstream water users at risk in the event...
Review of Phosphorus Control Measures in the United States and Their Effects on Water Quality
David W. Litke
1999, Water-Resources Investigations Report 99-4007
Historical information on phosphorus loadings to the environment and the effect on water quality are summarized in this report, which was produced as part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program. Phosphorus is a water-quality constituent of concern because it is often the limiting nutrient responsible for...

1999, Water-Resources Investigations Report 99-4006
A network of 148 low-flow partial-record stations was operated on streams in Massachusetts during the summers of 1989 through 1996. Streamflow measurements (including historical measurements), measured basin characteristics, and estimated streamflow statistics are provided in the report for each low-flow partial-record station. Also included for each station are location information,...

Robert L. Joseph
1999, Water-Resources Investigations Report 99-4035
During the spring of 1998, water levels were measured in 656 wells completed in the Mississippi River Valley alluvial aquifer in eastern Arkansas. Water samples were collected during the summer of 1998 from about 140 wells completed in the alluvial aquifer and measured for specific conductance, and samples from 119...

Simulated effects of water exchanges on streamflow and specific conductance in the Arkansas River upstream from Avondale, Colorado
Michael E. Lewis
1999, Water-Resources Investigations Report 98-4140
The potential effects of future water-exchange scenarios on streamflow and specific conductance in the Arkansas River were simulated with two accounting models. The major processes in the models simulated the historical exchange potential in the Arkansas River and the operation of a native and a nonnative Arkansas River water exchange....
Areal studies aid protection of ground-water quality in Illinois, Indiana, and Wisconsin
P.C. Mills, Robert T. Kay, Timothy A. Brown, Douglas J. Yeskis
1999, Water-Resources Investigations Report 98-4143
In 1991, the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, initiated studies designed to characterize the ground-water quality and hydrogeology in northern Illinois, and southern and eastern Wisconsin (with a focus on the north-central Illinois cities of Belvidere and Rockford, and the Calumet region of northeastern...
Preliminary aeromagnetic anomaly map of California
Carter W. Roberts, Robert C. Jachens
1999, Open-File Report 99-440
The magnetization in crustal rocks is the vector sum of induced in minerals by the Earth’s present main field and the remanent magnetization of minerals susceptible to magnetization (chiefly magnetite) (Blakely, 1995). The direction of remanent magnetization acquired during the rock’s history can be highly variable. Crystalline rocks generally contain...
USGS Science for Restoration of South Florida: The South Florida Ecosystem Program
Benjamin F. McPherson, Sarah Gerould, Aaron L. Higer
1999, Fact Sheet 061-99
As land and resource managers see the value of their resources diminish, and the public watches the environments they knew as children become degraded, there are increasing calls to restore what has been lost, or to build productive ecosystems that will be healthy and sustainable under the conditions of human...
Color infrared digital orthophoto quadrangles for the South Florida ecosystem area
Water Resources Division, U.S. Geological Survey
1999, Fact Sheet 163-96
The South Florida Ecosystem Restoration Program is an intergovernmental effort to reestablish and maintain the ecosystems of south Florida. One element of the restoration effort is the development of a firm scientific basis for resource decision making. The U.S. Geological Survey (USGS) is one of the agencies that provides scientific...
Hydrogeology of the surficial aquifer system in Southwest Florida
Water Resources Division, U.S. Geological Survey
1999, Fact Sheet 158-96
Restoration and management of the south Florida ecosystem will be guided by hydrologic models that simulate water flowing through the wetlands and shallow subsurface aquifers beneath them. The restoration of the ecosystem is, essentially, the restoration of the natural hydrologic system. As surface water is re-diverted from manmade canals to...
