Discovery Bay has a short history. It was begun as a planned community in 1964, and originally designated as "Riverside" and "River Lake."

In July 2007, Discovery Bay received its own ZIP code: 94505. Formerly it had shared 94514 with Byron. The ensuing celebration included a world record-setting paddle boat raft-up.
