19th century

The Augusta Canal was initially completed in 1845 as a source of water, power, and transportation for the city of Augusta. It was one of the few successful industrial canals in the Southern United States. During the time of construction, the city's Canal Commission was headed by Henry Harford Cumming. Cumming personally paid railroad engineer John Edgar Thomson to conduct the initial survey for the project. In 1847, construction began on the first factory, a saw and gristmill at the present site of Enterprise Mill. The Augusta Manufacturing Company, a sprawling four-story textile "manufactory", soon followed. They would be the first of many factories built along the Augusta Canal.

By the time of the Civil War, Augusta was one of the few manufacturing centers in the South. The power and water transportation afforded by the canal were among the factors that led Confederate Col. George Washington Rains to select Augusta as the location for the Confederate Powderworks. The 28 buildings, which were the only ones designed, constructed, and paid for by the government of the Confederate States of America, stretched for 2 miles (3.2 km) along the Augusta Canal. Other war industries were established along or near the canal, making Augusta an important center for materiel.

As the Civil War moved into Georgia in 1864, there was fear that US General William Tecumseh Sherman's troops would move to attack Augusta and her massive gunpowder factory. But Sherman's march through the South left Augusta untouched. As a result, the city ended the war in reasonably better physical and economic condition than many Southern cities. The population had doubled and hard currency was available to finance recovery, including expansion of the canal.

The canal was enlarged in 1875. A boom era saw the construction of the Enterprise Mill, King Mill, and Sibley Mill, the Lombard Ironworks; many other plants opened or expanded. Many people who lived on farms moved to the city to work at the mills, including women and children. The factories led to the rise of mill villages in their precincts.

In the 1890s, the city replaced its old water pumping station with impressive structure at mid-canal that is still used by the city of Augusta today. As the electric age began to dawn, Augusta began to turn the canal's falling water power to drive the first electrical generation equipment. By 1892, Augusta boasted both electric streetcars and street lights — the first Southern city to have these amenities.

20th century

Flooding was a big problem in Augusta during the early 20th century. Following major floods in the 1920s and 1930s, the Federal Works Progress Administration deployed hundreds of workers to make repairs and improvements, build a new spillway and to straighten the canal.

By the mid-20th century, the canal came into a period of neglect. Textile factories began to close and the city's industrial activity began to shift south of the city. At one point in the 1960s, city officials considered draining the canal to build a superhighway.

Flickers of interest in reviving the Augusta Canal began appearing in the 1970s. A state park was proposed, but never materialized. In 1989, the state legislature created the Augusta Canal Authority, the body that has jurisdiction over the canal today. In 1993, the Authority issued a comprehensive Master Plan, outlining the Canal's development potential. In 1996, the US Congress designated the Augusta Canal a National Heritage Area, the first such designation in Georgia.

The Augusta Canal Authority moved forward with its master plan. In 2003, the Augusta Canal Interpretive Center (now Discovery Center) opened in the revitalized Enterprise Mill. In late 2003 and early 2004, two modern-day Petersburg boats, inspired by the cargo vessels that once plied the canal with bales of cotton and farm goods, began operation for guided tours.

The King and the Sibley textile mills are now owned by the Augusta Canal Authority.
