The Decepticons attacked Hoover Dam to steal energy from it. This consisted of blasting holes in the top of it. The Autobots arrived and counter-attacked, driving them off, and the dam was saved.
Marvel Comics continuity
Bombshell used a cerebro-shell to force hydroelectric engineer Ricky Vasquez to bring Megatron into the energy plant at Hoover Dam, as part of the Decepticons' plan to steal the plant's energy and transport it to Cybertron via the space bridge. In response, Optimus Prime sent the newly built Aerialbots to hinder the Decepticons. Ricky Vasquez eventually regained control of his body and fired Megatron at the space bridge, saving the plant. Aerialbots over America!
