. Norris Dam is located at just over 79 miles (127.1 km) upstream from the mouth of the Clinch, immediately downstream from the river's confluence with Cove Creek, which joins the river from the northwest. The reservoir includes parts of Anderson, Campbell, Union, Claiborne, and Grainger counties. Norris Reservoir spans a 73 miles (117.5 km) stretch of the Clinch from the dam to River Ridge at the Claiborne-Grainger county line. The reservoir also covers the lower 56 miles (90.1 km) of the Powell River, which empties into the Clinch 10 miles (16.1 km) upstream from Norris Dam.

Background and construction

As early as 1911, the present site of Norris Dam— initially called the "Cove Creek site"— was identified as a prime location for a sizeable dam. Several government and private entities believed that a dam in the upper Tennessee Valley, working in conjunction with dams at Muscle Shoals, Alabama

— applied for permits to build a dam at the Cove Creek site, although all were eventually withdrawn or rejected. Part of the opposition was from Senator Norris, who advocated a government-sponsored dam at the site, arguing that a private entity would be almost wholly concerned with power generation rather than flood control and coordination with projects elsewhere in the valley. Norris proposed constructing a network of dams throughout the valley to help regulate its outflow into the lower Mississippi River

 legislation. The act authorizing TVA's establishment (signed on May 18, 1933) authorized TVA to immediately begin construction on a dam at the Cove Creek site. On July 30, TVA renamed the Cove Creek project for Senator Norris and began preparations for the dam's construction. As the agency lacked any engineering or dam construction experience, it relied heavily on the Army Corps' original design, and received ample consulting from the U.S. Bureau of Reclamation.

, located about 20 miles (32.2 km) upstream from the dam site, was entirely inundated. Approximately one-third of Caryville, at the head of the reservoir's Cove Creek embayment, was flooded and a number of structures in the town had to be moved. Several smaller 30 feet (9.1 m) earthen dams were built along reservoir tributaries to house fish hatcheries. As the project called for the construction of recreational areas along the lakeshore, TVA built two supplemental dams— Caryville Dam and Big Ridge Dam— to impound Cove Lake and Big Ridge Lake, respectively, and ensure these small lakes would remain filled year-round.

Norris Dam was completed and the gates closed on March 4, 1936, constructed at a cost of $36 million. The dam's first generator went online July 28, 1936. Although Norris was the first dam built by TVA, it is not the oldest dam owned and operated by the agency. TVA subsequently purchased the assets of the former Tennessee Electric Power Company, including some dams which had been built prior to Norris Dam. The building of Norris Dam and the changes it brought to the region inspired films, books, stage plays, and songs. Folk songs from the construction period express enthusiasm for the benefits that the dam project brought to the region.
