Savannah River Annotated Bibliography: January 2003 (1) HYDROLOGY, WATER QUALITY, AND GEOMORPHOLOGY (compiled by Rhett Jackson and Cody Hale) There are many sources of information on the hydrology, water quality, and geomorphology of the Savannah River system as outlined below. There appears to be only one effort to create a comprehensive summary of water quality information, and that is the Savannah River Basin Management Plan (GA EPD, 2001). In evaluating and analyzing this information, our primary areas of focus will be hydrologic modification by the reservoir system (as determined from pre- and post-project USGS flow data from the Augusta and Clyo gages), dredging modifications to the river channel, water demands (such as lake evaporation and water withdrawals from the Savannah River), current water quality conditions, and hydraulic analysis of floodplain connectivity. Below are listed the hydrologic data sources we believe to be most relevant to an evaluation of ecological flow restoration on the Savannah. General Hydrologic Data GA Department of Natural Resources, Environmental Protection Division. 2001. Savannah River Basin Management Plan 2001. Section 2.1.4, 4.1.3. Atlanta, GA. Section 2 gives a general overview of the Savannah River and its basin’s physical characteristics. Section 4 gives a brief evaluation of the temperature and flow modifications to the Savannah River and their affects. Meade, Robert H. May 1982. Sources, Sinks, and Storage of River Sediment in the Atlantic Drainage of the United States. The Journal of Geology. Vol. 90. No 3. The University of Chicago Press. Chicago, IL. This article addresses the issue of sediment transport from the point of erosion to its final storage point (salt marshes in the Lower Piedmont). Emphasizes the fact that a large amount of eroded material has yet to reach a water body and is being stored on the landscape. Thurmond Dam is mentioned directly as it notes it has a sediment trap efficiency of 80-90%. In the decade following the dam installation it was found that the sediment concentrations at the Augusta gage had decreases from pre-dam levels, however concentrations measured at the Clyo gage remained at the same levels. This has been attributed to the sediment previously stored in the lower reaches of the channel. Pearlstine, L.G., R. Bartleson, W.M. Kitchens, and P.J Latham. 1989. Lower Savannah River Hydrological Characterization. Technical Report No. 35. Florida Cooperative Fish and Wildlife Research Unit. Gainesville, FL. Paper has yet to be obtained. US Army Corps of Engineers, Savannah District, South Atlantic Division. April 1992. Lower Savannah River Environmental Restoration: Reconnaissance Report. pp. 12-13, 17 and 47. These pages contain descriptions of the Savannah River’s physical attributes, water quality classifications, statistical analyses on streamflow characteristics, and information on water releases during low flows. Flow regime as it pertains to water quality, wetlands, and fisheries is also addressed. 3
