Where is one major delta in Florida?

Florida is a peninsula surrounded by the Atlantic Ocean and the Gulf of Mexico. It contains numerous large rivers, including the St. Johns, Suwannee, and Apalachicola, but none of them form major deltas. The Apalachicola River enters the Gulf of Mexico through a series of distributaries, but it does not form a delta in the traditional sense. Therefore, there are no major deltas in Florida.
