Dams Construction
Norris Dam is a hydroelectric and flood control structure located on the Clinch River in Anderson County and Campbell County, Tennessee, United States. Its construction in the mid-1930s was the first major project for the Tennessee 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. The dam was named in honor of Nebraska Senator George Norris (1861–1944), a longtime supporter of government-owned power in general, and supporter of TVA in particular. The project infrastructure was listed on the National 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 the Tennessee 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 126 megawatts.
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, 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Company, and Union Carbide— applied for permits to build a dam at the Cove Creek site, although all were eventually withdrawn or rejected.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 lower Mississippi River. Throughout the late 1920s, the U.S. Army Corps of Engineers made several proposals to build a dam at the site, but all were rejected by Congress or vetoed by President Calvin Coolidge.
The Tennessee Valley Authority was formed in 1933 as part of President Franklin D. Roosevelt's New 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. 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.
Hungarian-American architect Roland Wank (1898–1970) revised the initial plans from Bureau of Reclamation engineers, and gave the poured-concrete Norris Dam a modernist 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. Construction began on October 1, 1933. More details
