Springfield Hydroelectric Dam

The Springfield Hydroelectric Dam is the only hydroelectric dam in Springfield.

History
The project to build the dam was managed by Cecil and Sideshow Bob. It was later discovered by Sideshow Bob, Bart and Lisa that the dam didn't have any cement inside, and the money for it was stolen by Cecil. He attempted to destroy the Dam with a bomb, in order to wipe out Springfield as a plot to frame Sideshow Bob as revenge for being made Krusty's Sideshow over himself. Sideshow Bob, Bart and Lisa 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, much to Homer's joy.

Non-canon
In The Simpsons Road Rage and The Simpsons: Hit & Run, the dam is under construction and there is an incomplete bridge next to it. In both games it is located near Kamp Krusty.

In The Simpsons Skateboarding, the dam is located in the level next to the gorge.
