Norris Dam is ahydroelectric andflood control structure located on theClinch River inAnderson County andCampbell County, Tennessee, United States. The dam was the first major project for theTennessee Valley Authority, which had been created in 1933 to bring economic development to the region and control the rampant flooding that had long plagued the Tennessee Valley.[1] The dam was named in honor ofNebraskaSenatorGeorge Norris (1861–1944), a longtime supporter of government-owned utilities in general, and of TVA in particular. The infrastructure project was listed on theNational Register of Historic Places in 2016.
Norris Dam is a straight concrete gravity-type dam. The dam is 1860 feet (570 m) long and 265 feet (81 m) high.Norris Lake, the largest reservoir on a tributary of theTennessee River, has 33,840 acres (137 km2) of water surface and 809 miles (1302 km) of shoreline. The dam has a maximum generating capacity of 126megawatts.[5]
The Clinch River flows southwestward for 300 miles (480 km) from its headwaters inVirginia through the rugged, sparsely populated hills of northeastern Tennessee before emptying into theTennessee River nearKingston. Norris Dam is located just over 79 miles (127 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, andGrainger counties. Norris Reservoir spans a 73-mile (117 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 km) of thePowell River, which empties into the Clinch 10 miles (16 km) upstream from Norris Dam. The dam's tailwaters are part of Melton Hill Lake, which stretches for 56 miles (90 km) along the Clinch from Norris toMelton Hill Dam.
Norris Freeway, a section ofU.S. Highway 441 widened in the 1930s to aid in dam construction, crosses the top of Norris Dam and connects the area toInterstate 75 atRocky Top, Tennessee to the west andKnoxville, Tennessee to the south. Along with the reservation maintained by TVA for the operation of Norris Dam, most of the lower Norris Reservoir is surrounded by conservation lands, includingNorris Dam State Park adjacent to the reservation, the Cove Creek Wildlife Management Area across the lake to the north, and the Chuck Swan State Forest, which protects a largely undeveloped area a few miles upstream.
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 atMuscle Shoals, Alabama, could provide badly needed flood control to East Tennessee and help keep the Tennessee River consistently navigable year-round. In the early 1920s, several entities—including the Tennessee Electric Power Company (TEPCo), the Knoxville Power & Light Company, andUnion Carbide— 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 lowerMississippi River. Throughout the late 1920s, theU.S. Army Corps of Engineers made several proposals to build a dam at the site, but all were rejected by Congress or vetoed by PresidentCalvin Coolidge.[1]
The Tennessee Valley Authority was formed in 1933 as part of PresidentFranklin D. Roosevelt'sNew Deal 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.[6] 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.[1] Hungarian-American architectRoland Wank (1898–1970) revised the initial plans from Bureau of Reclamation engineers, and gave the poured-concrete Norris Dam amodernist style, which was controversial and advanced for the era of construction, but the result would eventually succeed in elevating Roland Wank to the position of Chief Architect for TVA from 1933 through 1944.[7] Construction began on October 1, 1933.[8]
The building of Norris Dam and its accompanying reservoir required the purchase of over 152,000 acres (62,000 ha) of land. 2,841 families and 5,226 graves were relocated. The community ofLoyston, located about 20 miles (32 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-foot (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. TheCivilian Conservation Corps built recreational facilities and aided in the removal of various structures.[1] The town ofNorris, Tennessee was initially built as aplanned community to house the workers involved in the construction of this dam.[9]
Norris Dam was completed and the gates closed on March 4, 1936, constructed at a cost of $36 million (equivalent to $638 million in 2024[10]). The dam's first generator went online on 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 before Norris Dam.[1]
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.[11] Notable visitors to the dam included PresidentFranklin D. Roosevelt and First LadyEleanor Roosevelt, French philosopherJean-Paul Sartre, journalistErnie Pyle, Swiss architectLe Corbusier, track starJesse Owens, and Indian Prime MinisterJawaharlal Nehru.[12] In 1941, the dam was the subject of a photography exhibit at theMuseum of Modern Art in New York.[12]

The project's intent of providing aid to residents of the Clinch and Powell watershed has been argued by scholars and historians,[14] specifically regarding the TVA's acquisition of roughly 150,000 acres (61,000 ha) of farmland, and the displacement of an estimated 3,000 families and 5,300 graves. Many of the dead buried in cemeteries that were to be flooded by the dam reservoir were disinterred and reburied in four "re-interment cemeteries" established by the TVA: Baker's Forge Memorial Cemetery, Cumberland View Cemetery, Big Barren Memorial Cemetery, and New Loyston Memorial Cemetery.[15]
Union County, the most negatively impacted county of the Norris Project, would encounter the inundation of the unincorporated town ofLoyston and other scarce communities of the Big Valley region of Union County.[14] The town of Big Barren and the settlement of Baker's Forge were also inundated.[16] After the project's completion, the Big Valley region of Union County, promised its electrification by the project's end, would not receive electricity until the late 1940s and early 1950s. Some of the displaced in the aftermath of the Norris Project would commit suicide, unable to bear the stress of the loss of their lifestyles.[17]
