Springfield Hydroelectric Dam

The Springfield Hydroelectric Dam was the site of the Springfield Hydroelectric Dam Disaster. The project to build the dam was managed by Cecil and Bob Terwilliger. Cecil attempted to destroy the Dam with a bomb, in order to wipe out Springfield. Sideshow Bob, Bart and Lisa Simpson were able to foil Cecil's plans. The Dam was hollow and so exploded by itself, but the water just rushed through Springfield, not causing any damage. To pay for the Dam's reconstruction, the town sold the billboard rights to the structure to Duff Beer.
