History

Discovery Bay began as a planned community in 1964, and originally designated as "Riverside" and "River Lake." It was built on land known as the Byron Tract, which was previously used for growing barley and potatoes. In 1968, Jurgen Lunding led an effort to give the community its current name.

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