Associated Data for the Triangle Area Water Supply Monitoring Project, North Carolina, October 2015 - September 2017

These datasets contain information used to compile the report (USGS OFR 2019-xxxx). It contains water-quality data, analytical results of field blanks, and analytical results for environmental and replicate sample sets for surface-water samples collected during water years 2016 and 2017 for the Triangle Area Water Supply Monitoring Program (TAWSMP).

Model Input and Output for Hydrologic Simulations of the Southeastern United States for Historical and Future Conditions

This data release contains inputs for and outputs from hydrologic simulations of the southeastern U.S. using the Monthly Water Balance Model, the Precipitation Runoff Modeling System (PRMS), and statistically-based methods. These simulations were developed to provide estimates of water availability and statistics of streamflow for historical and potential future conditions for an area of approxima

Dataset of SPARROW model input and predictions for total nitrogen and total phosphorus in North Carolina

To better understand the influence of human activities and natural processes on surface-water quality, the U.S. Geological Survey (USGS) developed the SPARROW (SPAtially Referenced Regressions On Watershed attributes) (Schwarz and others, 2006; Alexander and others, 2008) model. The framework is used to relate water-quality monitoring data to sources and watershed characteristics that affect the f

SPARROW model dataset for total suspended solids in North Carolina, including simulated stream loads

To better understand the influence of human activities and natural processes on surface-water quality, the U.S. Geological Survey (USGS) developed the SPARROW (SPAtially Referenced Regressions On Watershed attributes) (Schwarz and others, 2006; Alexander and others, 2008) model. The framework is used to relate water-quality monitoring data to sources and watershed characteristics that affect the f

Water Quality Data for Bushy Park Reservoir, South Carolina 2013-2015

Water-quality data for the Bushy Park Reservoir near Goose Creek, South Carolina, from September 2013 to May 2015. Data includes the chemical, physical, and biological properties that influence (1) geosmin and 2-methyisobornel (MIB) occurrence in this source-water reservoir, (2) cyanobacterial biovolumes, and (3) geosmin-producing and toxin-producing genera of cyanobacteria. Data Release for USGS

Stream Lines Used to Produce the South Carolina StreamStats 2018 Release

The U.S. Geological Survey South Atlantic Water Science Center, in cooperation with the South Carolina Department of Transportation, implemented a South Carolina StreamStats application in 2018. This shapefile dataset contains vector lines representing streams, rivers, and ditches that were used in preparing the underlying data for the South Carolina StreamStats application. Data were compiled fro

Data and estimates for wet deposition and streamwater solute fluxes at Panola Mountain Research Watershed, Stockbridge, Ga., water years 1986-2016

This dataset contains the data and results of an analysis estimating wet deposition and streamwater solute fluxes at Panola Mountain Research Watershed (PMRW), Panola Mountain State Park, Stockbridge, Georgia for water years 1986-2016. The PMRW is a small (41 ha), relatively undisturbed, forested headwater catchment in the Piedmont Province of Southeastern United States. This data provides the bas

Autonomous Underwater Vehicle Water-Quality Measurements in Back River, Savannah, Georgia, 2018-2019

The Savannah Harbor Expansion Project (SHEP) began in January 2015 with the purpose of deepening the Savannah Harbor federal shipping channel to allow access to larger shipping vessels (U.S. Army Corps of Engineers, 2018a). There are various features and mitigation efforts to the SHEP, one of which is the installation of a dissolved-oxygen (DO) injection system at two locations along the Savannah

Stream habitat and geomorphic characteristics above and below culverts at selected sites in South Carolina (2017)

This dataset contains six individual tabular data files. These tabular data files contain measurements of aquatic habitat features and stream channel geomorphology from 20 sites in the Piedmont and Upper Coastal Plain physiographic regions of South Carolina. Specifically, the dataset titled "bedform_slope" contains enumeration of occurrence of bedforms, or macro-habitat features, and streambed and

MODFLOW-2000 and MODPATH used to evaluate groundwater-management scenarios in the Brunswick area, Georgia, 2004-2015

A previously published groundwater flow model (https://pubs.usgs.gov/sir/2005/5089/) was revised with refined grid spacing and updated hydrogeolgic framework and hydrologic properties (http://dx.doi.org/10.3133/sir20155061) and used in this study to predict the effects of Upper Floridan aquifer (UFA) groundwater pumpage on horizontal hydraulic-head gradients in the upper-water-bearing zone of the

Flood inundation and flood depth for the Yellow River in Gwinnett County, Georgia based on water-surface elevation at the U.S. Geological Survey streamgages Yellow River, near Snellville, Georgia (02206500) and Yellow River at Ga. 124, near Lithonia, Geor

The digital flood-inundation maps included in this data release were developed for a 16.4-mile reach of the Yellow River from 0.5-mile upstream of River Drive to Centerville Highway (Georgia State Route 124), Gwinnett County, Georgia (Ga.) to depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at two U.S. Geological Survey (USGS) streamgages i

Simulated hydrologic response in the Apalachicola-Chattahoochee-Flint River Basin, southeastern United States

The Apalachicola-Chattahoochee-Flint River Basin (ACFB), which is home to multiple fish and wildlife species of conservation concern, is regionally important for water supply and has been a recent focus of complementary water-resources, ecological, and climate-change research. As part of the U.S. Geological Survey (USGS) National Water Census, a water-availability study of the ACFB was conducted f
