on the Savannah
The Savannah River is a major river in the southeastern United States, forming most of the border between the states of South Carolina and Georgia. Two tributaries of the Savannah, the Tugaloo River and the Chattooga River, form the northernmost part of the border...
The Tugaloo River is a river bordering the U.S. states of Georgia and South Carolina. It is fed by the Tallulah River and the Chattooga River, which each form an arm of Lake Tugalo, on the edge of Georgia's Tallulah Gorge State Park. The Tugaloo then flows out of the lake via Tugaloo Dam,...
, and Seneca
The Seneca River is created by the confluence of the Keowee River and Twelvemile Creek in northwestern South Carolina, downriver from Lake Keowee near Clemson. It is now entirely inundated by Lake Hartwell, forming a arm of the lake. The Seneca River and the Tugaloo River join to form the Savannah...
Rivers. The lake is created by Hartwell Dam
Hartwell Dam is concrete and embankment dam located on the Savannah River at the border of South Carolina and Georgia, creating Lake Hartwell. The dam was built by the U.S. Army Corps of Engineers between 1955 and 1962 for the purposes of flood control, hydropower and navigation. The concrete and...

Extending 49 miles (78.9 km) up the Tugaloo and 45 miles (72.4 km) up the Seneca at normal pool elevation, The lake comprises nearly 56,000 acres (230 km²) of water with a shoreline of 962 miles (1,548.2 km). The entire Hartwell “Project” contains 76,450 acres (309 km²) of land and water. I-85

bisects Hartwell Lake and makes the area easily accessible to visitors.
The Flood Control Act of 17 May 1950 authorized the Hartwell Dam and Reservoir as the second unit in the comprehensive development of the Savannah River Basin.44 The estimated cost was $68.4 million based on 1948 price levels and preliminary designs. The original project provided for a gravity-type concrete dam 2,415 feet long with earth embankments at either end, which would be 6,050 feet long on the Georgia side and 3,935 feet long on the South Carolina side. The 12,400-foot-long dam was to be topped with a roadway 24 feet wide. The main dam was to consist of two nonoverflow concrete sections on the right and left banks 887 feet and 940 feet long, respectively; a gravity-type concrete spillway 588 feet long equipped with 12 tainter gates 26 feet by 40 feet in the channel; and a powerhouse on the South Carolina side of the river.45 Full power pool was designed to be 660 feet above mean sea level. At this elevation, the reservoir would extend 7.1 miles up the Savannah River to the confluence of the Tugaloo and Seneca Rivers; 41 miles up the Tugaloo to within approximately 2 miles of the existing Yonah Dam; 27 miles up the Seneca to the mouth of the Little River, South Carolina; 2 miles up the Little River to the Newry site; and 7 miles up the Keowee to the Old Pickens site. The reservoir would cover 56,500 acres and would involve the relocation of 3 sections of railroad totaling 2 miles, the raising of 2 railroad bridges, construction of 6 sections of new state high- ways totaling 19.6 miles and 9 sections of county roads totaling 12.7 miles, the construction of 9 new bridges and the raising of 4 existing bridges, and the relocation of 2 power transmission lines.
Lake Hartwell is named for the American Revolutionary War figure Nancy Hart

The Droughts and water levels of Lake Hartwell 1989 was the first year the lake hit a level 3 dropping to its lowest level during the drought that year. 2008 was the second time the lake hit a level 3.
In the year of 2008, due to severe drought in the southeastern United States, the lake dropped to over 22 feet (6.7 m) below its normal water level in December 2008. This revealed old highways that were typically underwater, exposed islands that are usually topped with buoys to warn boaters, and left some boat shells sitting on dry land.
As of the first of October 2010, the lake is back up to just over 654 feet, 6 ft lower than full pool of 660 ft. This rebound in lake level is due to releases from the lake being suspended for a month ending April 10, 2009 in an effort to return Lake Hartwell to normal elevations.
Since its construction, Hartwell Reservoir has provided good fishing habitat for many species. Bream, catfish, smallmouth bass, walleye, and largemouth bass are naturally occurring species in the lake, with quality fishing available for those species. The most popular fishing on Lake Hartwell, however, has become pursuing striped bass. Striped Bass, also known as rock fish, where discovered to be able to survive in freshwater after the construction of a dam on the Santee-Cooper system in lower South Carolina trapped many striped bass in fresh water. Striped bass were eventually introduced to the three lower Savannah River System lakes: Hartwell, Russel, and Thurmond. The species has done well, but due to the need for moving water to successfully hatch eggs, must continually be stocked in the lakes. These fish provide anglers with a fishing challenge more likened to saltwater fishing, with anglers tending to use larger boats, conventional reels, and oftentimes trolling techniques. State record fish have come from all three of the lakes holding "stripers" on the Savannah River system. 60+ lb. fish have been caught on Lake Hartwell, with 20 lb. fish being common. The majority of striped bass caught on the lake will range from 5 to 12 pounds.
There are many lake houses and docks on Lake Hartwell. Boating, water skiing, and fishing are popular activities on Lake Hartwell.
