Water withdrawals, use, discharge, and trends in Florida, 1995
R. L. Marella
1999, Water-Resources Investigations Report 99-4002
In 1995, the total amount of water withdrawn in Florida was nearly 18,200 million gallons per day (Mgal/d), of which 60 percent was saline and 40 percent was freshwater. Ground water accounted for 60 percent of freshwater withdrawals and surface water accounted for the remaining 40 percent. Ninety-three percent of...

The geohydrologic setting of Pololu stream, Island of Hawaii, Hawaii
Todd K. Presley
1999, Water-Resources Investigations Report 99-4009
Streamflow measurements indicate that Pololu Stream, which is on the northeastern side of Kohala Volcano, is intermittent, although the stream has previously been interpreted as perennial. The main channel of the stream does not gain water from ground-water sources except at a wetland and shallow pond at the terminus of...
Water resources of the Batavia Kill basin at Windham, Greene County, New York
Paul M. Heisig
1999, Water-Resources Investigations Report 98-4036
The water resources of a 27.6-square-mile section of the Batavia Kill Basin near the village of Windham, N.Y., which has undergone substantial development, were evaluated. The evaluation entailed (1) estimation of the magnitude and distribution of several hydrologic components, including recharge, (2) measurement of discharge and chemical quality of the...

Digital Map of Surficial Geology, Wetlands, and Deepwater Habitats, Coeur d'Alene River Valley, Idaho
Arthur A. Bookstrom, Stephen E. Box, Berne L. Jackson, Theodore R. Brandt, Pamela D. Derkey, Steven R. Munts
1999, Open-File Report 99-548
The Coeur d'Alene (CdA) River channel and its floodplain in north Idaho are mostly covered by metal-enriched sediments, partially derived from upstream mining, milling and smelting wastes. Relative to uncontaminated sediments of the region, metal-enriched sediments are highly enriched in silver, lead, zinc, arsenic, antimony and mercury, copper, cadmium, manganese,...
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....
Biotic integrity of the Boise River upstream and downstream from two municipal wastewater treatment facilities, Boise, Idaho, 1995-96
William H. Mullins
1999, Water-Resources Investigations Report 98-4123
Aquatic biological communities were used to assess the biotic integrity of the Boise River upstream and downstream from the Lander Street and West Boise municipal wastewater treatment facilities (WTFs) in Boise, Idaho. Samples of epilithic periphyton, benthic macroinvertebrates, and fish were collected in late February and early March 1995, in...
Sedimentation, sea-level rise and circulation in Florida Bay
Water Resources Division, U.S. Geological Survey
1999, Fact Sheet 156-96
Issue Recent algal blooms and seagrass mortality have raised concerns about the water quality of Florida Bay, particularly its nutrient content (nitrogen and phosphorus), hypersalinity, and turbidity. Water quality is closely tied to sediment transport processes because resuspension of sediments increases turbidity, releases stored nutrients, and facilitates sediment export to...
