NARRATOR: TVA launched an exodus of epic proportions. 15-thousand families were told they'd have to move--their property would be flooded by the backwash of the giant dams. Homes were bought by the government, and destroyed. The reservoirs would also claim the heart of the valley's agricultural community. 300-thousand acres of farmland would be flooded forever. The project was so invasive it would even disturb the dead. Entire cemeteries were un-earthed and moved to higher ground.
