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.
