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...

Ecosystem history: Terrestrial and fresh-water ecosystems of southern Florida
Water Resources Division, U.S. Geological Survey
1999, Fact Sheet 146-96
IntroductionPlant and animal communities of the historic Everglades have undergone striking changes over the last few decades, including declines in wading bird populations, invasion by exotic (non-native) plant and animal species, and areal expansion of cattails into sawgrass marshes. Many of these changes have been attributed to human activities in...

Sources of springs supplying base flow to the Verde River headwaters, Yavapai County, Arizona
Laurie Wirt, H. W. Hjalmarson
1999, Open-File Report 99-378
Multiple lines of evidence were used to identify source aquifers, quantify their respective contributions, and trace the ground-water flow paths that supply base flow to the uppermost reach of the Verde River in Yavapai County, Arizona. Ground-water discharge via springs provides base flow for a 24-mile long reach from the mouth of Granite Creek (river mile 2.0)...

1999, Open-File Report 99-349
Planners need to evaluate complex and competing public-policy options for managing water, land, and biological resources; they must ensure economic growth, meet the needs of an increasing population, assess hazards, and manage the environment in a sustainable manner. The State Geological Surveys of Illinois, Indiana, Michigan, and Ohio and the...

The total amount of water withdrawn in Illinois during 1992 was about 19,076 (Mgal/d) million gallons per day. About 16,101 Mgal/d, or about 84 percent of this total, was withdrawn for thermoelectric-power generation, and about 1,877 Mgal/d was withdrawn by and delivered from public-supply facilities. About 1,910 Mgal/d of surface...
