Sebastian Inlet officially opened in 1923; however, efforts to dig it out and open the flow to the lagoon date all the way back to 1872.
With the influx of settlers to the area during the mid-to-late 1800’s and into the 1900’s the quality of the stagnant water of the lagoon quickly diminished. The solution was to open up the lagoon to the ocean. At least six recorded attempts were made prior to 1923, all failing due to sand, storms and other natural causes filling in the cut.
As fortune favors the bold, the dredging of the inlet in 1923 worked with the aid of jetties and thankfully, Sebastian Inlet is what saved the community in the years to come.
In 1929 the United States plunged head-first into one of the most difficult decades, The Great Depression. With poverty gripping most families, people in the area turned to Sebastian Inlet for fishing to not only feed themselves, but also to bring in money. Commercial fishing turned out to be the saving grace for many families. Railroads in the area and the advent of ice plants rendered the ability to increase the catch and enabled shipment of fish to inland markets.
Sadly, Sebastian Inlet didn’t last long as a strong Nor’easter in the winter of 1941 closed the inlet. With the United States involvement in World War II following the attack on Pearl Harbor, the inlet remained closed for safety reasons as German U-Boats were commonly spotted off the coast of Florida.
Following the War, the US Navy Demolitions Unit who trained just south of Sebastian left a surplus of explosives behind that was used to blast the inlet open once again. Learning from past mistakes, a larger jetty was planned on each side of the inlet and constructed continued throughout the 1950’s until it’s completion.
Sebastian Inlet has remained open since then.
