Palm Beach Inlet

also known as the Lake Worth Inlet

About the Palm Beach Inlet, aka the Lake Worth Inlet:

An artificial cut through a barrier island connecting the northern part of the Lake Worth Lagoon in Palm Beach County, Florida with the Atlantic Ocean. It is bordered by the town of Palm Beach on the south, and by the town of Palm Beach Shores to the north. The inlet is also the entrance channel for the Port of Palm Beach.


n the mid-19th century the body of water that is now the Lake Worth Lagoon was a freshwater lake. This had been named Lake Worth in honor of William J. Worth, commander of the Eighth Infantry Regiment in the Second Seminole War. There were no rivers or streams flowing into the lake; all of the flow into the lake was by ground seepage from the Everglades to the west. The only outflow from the lake was through a swamp that became the Lake Worth Creek as it approached the Loxahatchee River and Jupiter Inlet.

The Lake Worth Inlet has been improved several times over time. The federal government assumed responsibility for the inlet in 1935, and continued to widen and deepen it and build up the jetties. In 1967 the inlet was dredged to a depth of 35 feet, which has been maintained since then. A sand transfer plant pumps sand from the north side of the inlet to the south side in order to maintain the natural flow of sand southward along the coast.
