Savannah River Annotated Bibliography: January 2003 Middle River was considered suitable. Under low flow conditions: Portions of the Back River (up to 6.5 miles upriver of the Front River confluence) became unsuitable for striped bass eggs and larvae. Most of the Middle River except for the lowest reaches were suitable. The Front River had mostly toxic levels up to the Hoolihan Bridge (river mile 21.5). These flow levels are unlikely during the striped bass spawning season but serve as a ‘worst-case scenario’. Reinert, T.R., J. Wallin, and M.J. Van Den Avyle. 1996. Abundance and distribution of striped bass eggs and larvae in the Savannah River estuary-Implications for channel dredging window, 1994-1996. Final Report, U.S. Army Corps of Engineers Savannah District. Georgia Cooperative Fish and Wildlife Research Unit, Daniel B. Warnell School of Forest Resources, University of Georgia, Athens, Ga. 30602. The general objectives of this study were to determine the timing of striped bass spawning, define the spatial distribution of eggs and larvae, and examine how watermass transport affects distribution of spawned eggs throughout the estuary. Most eggs (86%) were collected in the upper Front River (river miles 24-31). Most eggs (99.5%) were captured from March 23 to May 10 each year. Based on float study results, eggs spawned in the upriver areas (river miles 24-31) would be jeopardized by rapid transport to the harbor area, where they could be exposed to dredging and maintenance activities and areas of high salinity. Conversely, eggs spawned in the Back River area (Back River miles 10 and above) would, during periods of low river discharge, remain in the Back River. Rulifson, R. A. and C. S. Manooch III. 1990. Recruitment of Juvenile Striped Bass in the Roanoke River, North Carolina, as Related to Reservoir Discharge. North American Journal of Fisheries Management. 10: 397-407. Juvenile abundance index (JAI) values for young-of-year striped bass in Abermarle Sound (1955-1987) were compared to preimpoundment and post-impoundment flows of the Roanoke River during the spawning season. Recruitment was best (JAI > 5.0) for years in which river flows were low to moderate (5,000-11,000 ft3/s) and was poor (JAI < 5.0) when flows were very low (3.900-8,100 ft3/s) or high (10,000 ft3/s or greater) during spawning season. Additionally, the average flow pattern for good recruitment years (JAI > 5.0) most closely resembled preimpoundment flow conditions. Preimpoundment flow patterns were used to develop a recommended flow regime for the lower river. Secor, D.H., T.E. Gunderson, and K. Karlsson. 2000. Effect of temperature and salinity on growth performance in anadromous (Chesapeake Bay) and nonanadromous (Santee-Cooper) strains of striped bass Morone saxatilis. Copeia. 2000, 291-296. Growth rates of striped bass Morone saxatilis were compared between anadromous (Chesapeake Bay) and nonanadromous (Santee-Cooper) stocks. Early growth rates are probably inversely related to latitude. Growth rates for both stocks at given temperatures and salinities are provided. Stevens, D.E. 1977.

Current status of information on striped bass in the Savannah River Estuary This document provides a thorough review of Savannah River striped bass studies. Egg density, abundance, and transport, stocking programs, reproductive status, distribution, and water quality related to striped bass are all considered. Van Den Avyle, M.J., and M.A. Maynard. 1994. Effects of saltwater intrusion and flow diversion on reproductive success of striped bass in the Savannah River Estuary. Transactions of the American Fisheries Society. 123, 886-903. Striped bass Morone saxatilis reproduction following recruitment failure was studied in the late 1980’s. Their study suggests that egg and larval dispersal and transport to areas with harmful salinity levels was responsible for reproduction failure. Maintenance of freshwater on the spawning grounds and prevention of rapid flushing of eggs and larvae into saline areas may restore reproduction conditions. Discussion section presents the following historic flow/salinity information from Pearlstine et al. (1990) : At a discharge of 170 m3/sec., the salt wedge extended upriver only to about km 32, whereas in the 1980’s, the salt wedge extended to km 37 without tidegate operation and with discharges of 165-180 m3/sec. (Pearlstine 1990). Under average tidal conditions, salinity at km 38 of the Savannah River exceeded 0.5 ppt. When flow was less than 230 m3/sec. and the tide gate was operating (Pearlstine et al. 1990). VanDenAvyle recommends managing salinity at the estuarine spawning grounds by regulation of water releases from J. Strom Thurmond Dam, and mentions that freshwater conditions needed for spawning could probably be assured by maintaining flows above 230 m3/sec. He does however, note concern over possible acceleration of egg and larval transport downstream to harmful salinities. Van Den Avyle, M.J., M.A. Maynard, R.C. Klinger, and V.S. Blazer. 1990.
