Selected hydrologic data for the upper Rio Hondo basin, Lincoln County, New Mexico, 1945-2003
Lisa C. Donohoe
2004, Scientific Investigations Report 2004-5275
Demands for ground and surface water have increased in the upper Rio Hondo Basin due to increases in development and population. Local governments are responsible for land-use and development decisions and, therefore, the governments need information about water resources in their areas. Hydrologic data were compiled for the upper Rio...

Tannins and terpenoids as major precursors of Suwannee River fulvic acid
Jerry A. Leenheer, Colleen E. Rostad
2004, Scientific Investigations Report 2004-5276
Suwannee River fulvic acid (SRFA) was fractionated into 7 fractions by normal-phase chromatography on silica gel followed by reverse-phase fractionation on XAD-8 resin that produced 18 subfractions. Selected major subfractions were characterized by 13C-nuclear magnetic resonance (NMR), infrared spectrometry, and elemental analyses. 13C-NMR spectra of the subfractions were more indicative...
Nutrient enrichment, phytoplankton algal growth, and estimated rates of instream metabolic processes in the Quinebaug River Basin, Connecticut, 2000-2001
Michael J. Colombo, Stephen J. Grady, Elaine C. Todd Trench
2004, Scientific Investigations Report 2004-5227
A consistent and pervasive pattern of nutrient enrichment was substantiated by water-quality sampling in the Quinebaug River and its tributaries in eastern Connecticut during water years 2000 and 2001. Median total nitrogen and total phosphorus concentrations exceeded the U.S. Environmental Protection Agency?s recently recommended regional ambient water-qual-ity criteria for streams (0.71...
A method for simulating transient ground-water recharge in deep water-table settings in central Florida by using a simple water-balance/transfer-function model
Andrew M. O’Reilly
2004, Scientific Investigations Report 2004-5195
A relatively simple method is needed that provides estimates of transient ground-water recharge in deep water-table settings that can be incorporated into other hydrologic models. Deep water-table settings are areas where the water table is below the reach of plant roots and virtually all water that is not lost to...
Hydrogeology and Water Quality of the Pepacton Reservoir Watershed in Southeastern New York. Part 3. Responses of Stream Base-Flow Chemistry to Hydrogeologic Factors and Nonpoint-Sources of Contamination
Paul M. Heisig, Patrick J. Phillips
2004, Scientific Investigations Report 2004-5008
Base-flow samples were collected seasonally from 20 small streams in the 372-square-mile Pepacton Reservoir watershed to evaluate the effects of hydrogeologic factors and nonpoint sources of contamination on the chemical composition of ground-water discharge. The reservoir provides part of New York City?s water supply. The subbasins represented one of three...

William J. Wolfe, Jonathan P. Evans, Sarah McCarthy, W. Scott Gain, Bradley A. Bryan
2004, Water-Resources Investigations Report 2003-4217
Multiple lines of evidence point to climate change as the driving factor suppressing tree regeneration since 1970 in Sinking Pond, a 35-hectare seasonally flooded karst depression located on Arnold Air Force Base near Manchester, Tennessee. Annual censuses of 162-193 seedling plots from 1997 through 2001 demonstrate that the critical stage...

Hydrogeology and water quality of the Pepacton Reservoir Watershed in southeastern New York. Part 4. Quantity and quality of ground-water and tributary contributions to stream base flow in selected main-valley reaches
Paul M. Heisig
2004, Scientific Investigations Report 2004-5018
Estimates of the quantity and quality of ground-water discharge from valley-fill deposits were calculated for nine valley reaches within the Pepacton watershed in southeastern New York in July and August of 2001. Streamflow and water quality at the upstream and downstream end of each reach and at intervening tributaries were...
Water quality, hydrology, and the effects of changes in phosphorus loading to Pike Lake, Washington County, Wisconsin, with special emphasis on inlet-to-outlet short-circuiting
William J. Rose, Dale M. Robertson, Elizabeth A. Mergener
2004, Scientific Investigations Report 2004-5141
Pike Lake is a 459-acre, mesotrophic to eutrophic dimictic lake in southeastern Wisconsin. Because of concern over degrading water quality in the lake associated with further development in its watershed, a study was conducted by the U.S. Geological Survey from 1998 to 2000 to describe the water quality and hydrology...
Extent of areal inundation of riverine wetlands along five river systems in the upper Hillsborough river watershed, west-central Florida
B. R. Lewelling
2004, Scientific Investigations Report 2004-5133
Riverine and palustrine wetlands are a major ecological component of river basins in west-central Florida. Healthy wetlands are dependent, in part, upon the frequency and duration of periodic flooding or inundation. This report assesses the extent, area, depth, frequency, and duration of periodic flooding and the effects of potential surface-water...
Hydrology and cycling of nitrogen and phosphorus in Little Bean Marsh: A remnant riparian wetland along the Missouri River in Platte County, Missouri, 1996–97
Dale W. Blevins
2004, Scientific Investigations Report 2004-5171
The lack of concurrent water-quality and hydrologic data on riparian wetlands in the Midwestern United States has resulted in a lack of knowledge about the water-quality functions that these wetlands provide. Therefore, Little Bean Marsh, a remnant riparian wetland along the Missouri River, was investigated in 1996 and 1997 primarily...
Integrated monitoring of hydrogeomorphic, vegetative, and edaphic conditions in riparian ecosystems of Great Basin National Park, Nevada
Erik A. Beever, D.A. Pyke
2004, Scientific Investigations Report 2004-5185
In semiarid regions such as the Great Basin, riparian areas function as oases of cooler and more stable microclimates, greater relative humidity, greater structural complexity, and a steady flow of water and nutrients relative to upland areas. These qualities make riparian areaʼs attractive not only to resident and migratory wildlife,...
Global change impacts on mangrove ecosystems
Karen L. McKee
2004, Fact Sheet 2004-3125
Mangroves are tropical/subtropical communities of primarily tree species that grow in the intertidal zone. These tidal forests are important coastal ecosystems that are valued for a variety of ecological and societal goods and services. Major local threats to mangrove ecosystems worldwide include clearcutting and trimming of forests for urban, agricultural,...

Although hurricanes have...
Natural restoration basics for wetlands
Beth A. Middleton
2004, Fact Sheet 2004-3053
Around the world, dams, diversions, and drainage systems reengineer rivers for navigation, farming, and urban development, and this has caused vast changes in the environmental conditions of the flood plains adjacent to these rivers (Middleton, 2002). Even though “flood pulses,” the periodic overflow of these rivers, were once the most...

Chloroform in the hydrologic system--sources, transport, fate, occurrence, and effects on human health and aquatic organisms
Tamara Ivahnenko, Jack E. Barbash
2004, Scientific Investigations Report 2004-5137
Chloroform is one of the volatile organic compounds (VOCs) detected most frequently in both ground and surface water. Because it is also one of the four trihalomethanes (THMs) produced in the highest concentrations during the chlorination of drinking water and wastewater, the frequent detection of this compound in ground and...
Loads and yields of selected constituents in streams and rivers of Monroe County, New York, 1984-2001
Donald A. Sherwood
2004, Water-Resources Investigations Report 2003-4197
Hydrologic data collected in Monroe County since the 1980s and earlier, including long-term records of streamflow and chemical loads, provide a basis for assessment of water-management practices. All monitored streams except Northrup Creek showed a slight (nonsignificant) overall decrease in annual streamflow over their period of record; Northrup Creek showed...
