How was Biscayne Bay formed? Biscayne Bay formed as sea level rose to fill a depression in the limestone between 5,000 and 2,400 years ago. During and since that time sandy barrier islands, banks of carbonate sand and mud, and coastal wetland swamp and marsh deposits have grown and evolved to give the bay its present form.
