To address the data and information gap for characterizing coastal drought, a coastal salinity index (CSI) was developed using salinity data (Conrads 2016; Conrads and Darby, 2017). The CSI uses an approach similar to the Standardized Precipitation Index (SPI), a readily available drought index that is widely used for monitoring meteorological droughts (McKee and others, 1993). The CSI substitutes total monthly precipitation with monthly mean salinity data to determine the probability of recording a given salinity value in a particular month. The initial investigation demonstrated that the index could be used to delineate short- and long-term drought (saline) and wet (high freshwater inflow) conditions; however,...

The Bushy Park Reservoir is a relatively shallow impoundment in a semi-tropical climate and is the principal water supply for the 400,000 people of the City of Charleston and the surrounding areas including the industries in the Bushy Park Industrial Complex. Although there is an adequate supply of freshwater in the reservoir, there are taste-and-odor water-quality concerns. The U.S. Geological Survey (USGS) worked in cooperation with the Charleston Water System to study the hydrology and water-quality of the Bushy Park Reservoir to identify factors affecting water-quality conditions. This data release is for the water-quality data collected with an autonomous underwater vehicle (AUV) for a water-quality study of...

Surface-water supplies are important sources of drinking water for residents in the Triangle area of North Carolina, which is located within the upper Cape Fear and Neuse River Basins. The region has undergone, and continues to undergo, profound increases in population and land use change, which increases the demand on drinking water supplies, the majority of which are drawn from streams and surface reservoirs. Municipal suppliers obtain raw water from reservoirs and rivers in the Triangle area, which encompasses the area between the cities of Raleigh, Durham, and Chapel Hill, NC. Since 1988, the U.S. Geological Survey and a constortium of local governments have participated in a cooperative effort, known as the...

This U.S. Geological Survey Data Release contains the associated data described in the Scientific Investigations Report, "Trends in water quality of selected streams and reservoirs used for water supply in the Triangle area of North Carolina, 1989-2013". Since 1989, the U.S. Geological Survey and a consortium of local governments have tracked water-quality conditions and trends in the water-supply reservoirs and streams in the Triangle area of North Carolina located within the upper Cape Fear and Neuse River Basins. Temporal trends in water-quality were analyzed for thirteen stream and eight reservoir sites. Seventeen water-quality parameters and constituents were examined at these sites.

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 River to maintain pre-SHEP DO levels in the harbor (U.S. Army Corps of Engineers, 2018b). The injection systems are installed upstream near Georgia Power Plant McIntosh in Effingham County, Georgia and downstream near Hutchinson Island, Chatham County, Georgia. Designed to maintain DO levels in the harbor as they were before...

Tidal cycle water velocities were measured at transects in the Bushy Park Reservoir using Teledyne Rio Grande 1200 kHz acoustic Doppler current profilers (ADCP). Five transects were measured on August 5, 2014 and November 5, 2014, and two transects were measured on March 26, 2015 and April 23, 2015. The data were collected every 30 minutes over a tidal cycle . The data were georeferenced with differential GPS receivers with submeter accuracy. Data were processed using the "Velocity Mapping Toolbox" (Parsons et al., 2013). Any data assigned a value of "­-9999" are bad or missing data and should not be used for analysis. Parsons, D. R., Jackson, P. R., Czuba, J. A., Engel, F. L., Rhoads, B. L., Oberg, K. A., Best,...

Vertical velocities profiles were measured at 15-minute intervals at six locations in the Bushy Park Reservoir using self-contained Sontek Argonaunt XRs upward-facing acoustic Doppler current profilers (ADCPs) with a frequency of either 1,500 or 3,000 kiloHertz (kHz)). The ADCPs were deployed between December 2013 and May 2015. Up to four sites were collected concurrently. Data were processed using ViewArgonaut, a software package developed by SonTek (http://www.sontek.com/softwaredetail.php?ViewArgonaut-Software-21) to compute the average velocity vector (magnitude and direction) for each time step (15-minute) at the location.
