Bayocean, Oregon: The Town That Fell Into the Sea

Bayocean, Oregon is a vanished resort ghost town in Tillamook County, built on a sand spit between the Pacific Ocean and Tillamook Bay. It was marketed as the 'Queen of Oregon Resorts' and the 'playground of millionaires.' Its residents accidentally destroyed it by building a jetty that redirected the ocean's currents directly into their own town.

01Why Was Bayocean Founded?

In 1906, Thomas Benton Potter and his son Thomas Irving Potter — real estate promoters with offices in Portland, San Jose, San Francisco, and Kansas City — began building a resort community on the narrow sand spit that forms the western wall of Tillamook Bay. The location was spectacular: ocean on one side, bay on the other, the Oregon coast's dramatic headlands visible from every lot.

The Potters promised a world-class destination. They built paved and lighted streets, a private railroad, a three-story luxury hotel, a thousand-seat movie theater, and a 160-foot-long heated saltwater swimming pool — one of the largest on the West Coast. A general store, post office, public school, bakery, bowling alley, tennis courts, golf links, trap-shooting range, and a Methodist church filled out the community.

The post office opened on February 4, 1909. By 1914, two thousand people called Bayocean home.

02The Jetty

Bayocean's location on a sand spit meant it was exposed to Pacific storm waves. Residents petitioned the Army Corps of Engineers for protection. The Corps recommended two jetties — one on each side of Tillamook Bay's mouth — at a cost of $2.2 million, with residents paying half.

The price was too high. Bayocean's citizens proposed a single jetty, built on just one side of the bay mouth, for about $800,000. It was constructed.

The single jetty changed the ocean's behavior. Currents that had previously deposited sand along the spit now carried it away. Bayocean's beaches began narrowing. Then they began disappearing.

03The Slow Drowning

Erosion accelerated through the 1920s and 1930s. The hotel was demolished. The natatorium (swimming pool building) was undermined and collapsed. Streets buckled. Houses were moved inland, then moved again, then abandoned as the spit continued to narrow.

Bayocean became a ghost town slowly, not suddenly. Each winter storm took more of the spit. Each year, fewer residents remained. The town that was supposed to be the playground of millionaires was being consumed by the engineering decision its own residents had insisted upon.

04What Remains of Bayocean Today

Virtually nothing. The site is now Bayocean Peninsula County Park — a hiking and nature area on what remains of the sand spit. A commemorative sign at the south end of the park is the only marker. The streets, buildings, pool, theater, hotel, railroad, and 2,000 residents are all gone.

Hikers on the spit walk over ground where a town of two thousand once stood. During extreme low tides, fragments of the original street grid are occasionally visible. The Oregon Encyclopedia, OPB, and the Oregon Secretary of State Archives all maintain detailed accounts of the rise and fall of Bayocean.
