Formerly: Discarding pollution
|First Appearance||"Gone Fishin'"|
The lake contains rapids and rocks. It also has a waterfall on one end.
The lake was a huge source of pollution, being the dumping site for waste from the nuclear power plant, and eventually, the entire town. The polluted lake claimed the lives of at least one rock band. An effort to clean up the lake by Lisa and Colin succeeded, and a shoulder-height concrete barrier was constructed by Mayor Quimby to prevent any "idiot" from dumping into the lake. However, the wall didn't stop Homer, who re-polluted the lake with his and his pet pig's waste, causing some animal life and the entire lake to mutate, and forcing the Environmental Protection Agency to intervene by trapping Springfield inside a giant glass dome, however, it did stop Cletus Spuckler from dropping his waste in the lake.
