The Tugaloo River/Seneca River Basin encompasses 1,269 square
miles that extends across the Blue Ridge and Piedmont regions of the State. The
Tugaloo River/Seneca River Basin encompasses 13 watersheds and 811,957 acres, of
which 71.7% is forested land, 16.3% is agricultural land, 6.5% is water, 4.5% is
urban land, 0.6% is forested wetland, and 0.4% is barren land. The urban land
percentage is comprised of numerous small towns and cities. There are
approximately 1,441 stream miles and 58,392 acres of lake waters in this
basin.
The Chattooga River flows across the North Carolina/South
Carolina state line and flows between the states of South Carolina and Georgia.
The Chattooga River then flows through Tugaloo Lake and Lake Yonah, becoming the
Tugaloo River. The Tugaloo River accepts drainage from the Chauga River and
other smaller streams before joining the Seneca River.
The Whitewater River and the Toxaway River join to form
the Keowee River in Lake Jocassee near the North Carolina border. The Keowee
River flows out of the Lake Jocassee Dam and into Lake Keowee. The Keowee River
flows out of the Keowee Dam and merges with the Little River coming out of the
Little River Dam to form the Seneca River and Lake Hartwell. The Seneca River
within Lake Hartwell accepts drainage from Twelvemile Creek, Coneross Creek,
Eighteenmile Creek and Three and Twenty Creek. The Tugaloo River converges with
the Seneca River within Lake Hartwell to form the Savannah River.
