Sustainable Rivers

Savannah River, GA & SC - Developing new approaches to meet multiple needs

The Savannah River provides drinking water for more than one million people and hosts numerous endangered, threatened and rare species of plants and animals. The three Corps dams on the river included in SRP activities generate hundreds of millions of kilowatt hours of hydroelectricity each year. The reservoirs at J. Strom Thurmond Dam, Richard B. Russell Dam and Hartwell Dam are visited by a total of more than one million people annually.

Because of the river's vital importance, the Corps and Conservancy are modifying reservoir operations to maintain and even enhance the many services provided by the Savannah, particularly in the face of continuing drought conditions.

In 2003, a group of scientists, engineers, and water managers defined a set of environmental flow recommendations for the Savannah River below Thurmond Dam.

New Savannah Bluff Lock and Dam is shown during the 2004 pulse release. When flows in the Savannah exceed 16,000 cubic feet per second, the gates of the structure are raised, which scientists hypothesized would encourage fish passage through the structure.

The Savannah collaboration began when the Conservancy initiated discussions with Savannah District regarding conservation hopes for the river. Initial environmental flows work aligned with the Savannah River Basin Comprehensive Study, which was a planning effort to better understand current and future water resources needs in the basin.

The Savannah River below the Augusta Canal diversion is characterized by numerous rock structures called shoals.  Shoals river reaches provide important fish spawning and rearing habitat in the Savannah River.

Story

The Savannah River has been altered by hydrologic regulation and channel modification in the past half century. J. Strom Thurmond Dam is the lowermost of three large dams operated by the Army Corps of Engineers on the Savannah River, which forms the border between Georgia and South Carolina.

The Lower Savannah River, flows downstream from Thurmond Dam approximately 185 miles and supports several types of ecosystems such as floodplains and river shoals, and provides habitats for a diverse array of species.   Read More
