Weiss, Hydroelectric reservoir in Cherokee County and Floyd County, United States

Weiss Lake is a reservoir on the Coosa, Chattooga and Little rivers in Cherokee County and Floyd County, Alabama, held back by Weiss Dam. At full summer pool it sits 564 feet (172 m) above sea level and covers 30,200 acres, with 447 miles (719 km) of shoreline of shallow flats, large coves, underwater drop-offs and deep channels. Eleven bridges cross it, and its near shore is lined with rough grey rocks and patches of weeds.

The dam construction began in 1958 as the first of seven hydroelectric projects along the Coosa River and was completed in June 1961. The facility took its name from Fernand C. Weiss, a former chief engineer at Alabama Power.

Weiss Lake takes its name from Fernand C. Weiss, a former chief engineer of Alabama Power, and the reservoir is owned and operated by the company. The Rome Sailing Club, founded at Garden Lakes in 1955, moved its activities to Weiss Lake in 1980. Local newspaper editor Douglas Scott Wright wrote A History of Weiss Lake, recounting the decades-long fight to build the dams and the farmers who opposed the Weiss Dam.

Access is available through four public launch sites and 37 marinas distributed along the shoreline. Campgrounds and lodging options line the water for extended visits, particularly during warmer months.

The dam combines a 126-foot (38-meter) concrete structure with earthen embankments in an unusual mixed design. The reservoir extends into three counties and connects different communities along its shores.
