The Nature Conservancy (TNC) has been working with the U.S. Fish and Wildlife Service (USFWS), the U.S Army Corps of Engineers – Savannah District (USACE - Savannah) and other stakeholders on environmental flow recommendations for the Savannah River since May 2002 and have recently (2015) updated the environmental flow recommendations from 2003. Analysis of the flow data revealed a large amount of flow variability on sub-daily basis in the reach of the Savannah River from the Augusta Shoal downstream to the New Savannah Lock and Dam. The sub-daily flow variability affects sustaining suitable habitat during critical periods to promote fish spawning of robust redhorse, shad, and Atlantic sturgeon. The cause of the...
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. This data release supports the following publication: Conrads, P.A., Journey, C.A., Petkewich, M.D., Lanier, T.H., and Clark, J.M., 2018, Characterization of water quality in Bushy Park Reservoir, South Carolina, 2013–15: U.S. Geological Survey Scientific Investigations Report 2018–5010, 175 p., https://doi.org/10.3133/sir20185010.

A critical aspects of the uniqueness of coastal drought is the effects on salinity dynamics of creeks and rivers. The location of the freshwater-saltwater interface along the coast is an important factor in the ecological and socio-economic dynamics of coastal communities. Salinity is a critical response variable that integrates hydrologic and coastal dynamics including streamflow, precipitation, sea level, tidal cycles, winds, and tropical storms. The position of the interface determines the composition of freshwater and saltwater aquatic communities as well as the freshwater availability for water intakes. Many definitions of drought have been proposed, with most describing a decline in precipitation which has...

The Indian River Lagoon (IRL) extends for 160 miles along Florida's east coast and is a complex system of three estuaries - Mosquito Lagoon, Banana River Lagoon, and Indian River Lagoon. Two concurrent phytoplankton blooms occurred in the IRL in 2011 that had detrimental ecological effects on the estuarine system. St. Johns River Water Management District (SJRWMD) is participating in a multi-agency effort to better characterize and understand the factors effecting algal dynamics of the IRL. The U.S. Geological Survey (USGS) worked in cooperation with the SJRWMD to study the spatial variability of water-quality conditions, especially conditions related to potential algal blooms, between sampling sites and the spatial...
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 hydrodynamics of the Bushy Park Reservoir to identify factors impacting water-quality conditions. This data release is for the hydrodynamic data collected during the study to support the application and calibration of a 3-dimensional...

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.
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), in cooperation with the Charleston Water System, monitored the hydrology and water-quality conditions in the Bushy Park Reservoir immediately before, during, and after a unique shutdown period when the average daily 800-cubic-feet-per-second withdrawals by South Carolina Electric and Gas (SCE+G) Williams Station...
