It was Dexter Morgan’s dumping spot for his victims until it was chanced upon by scuba divers in “It’s Alive!” He then began to discard remains directly into the Gulf Stream, a powerful oceanic current.

Due to the killer’s moniker (The Bay Harbor Butcher), the graveyard was likely a few miles off the coast of Bay Harbor Islands - a town separated from the mainland by Biscayne Bay. Since the average depth of Biscayne Bay is only 10 feet, Dexter would’ve needed to dump his victims into the Atlantic Ocean.

Before Dexter began dumping his victims at sea, he used other methods, such as burying them or leaving them for alligators in the Everglades. When Dexter tried to incinerate Gene Marshall’s body parts, it caused an explosion. He then looked for a better way to dispose of his victims.
In the Early Cuts storyline, Dexter purchased a fishing boat from Marshall's psychiatrist, Dr. Greenstein. He docked his boat at Coral Cove Marina, and used nearby rocks to weigh down the body bags so they wouldn’t float to the surface. Later, Dexter moved his boat to another marina to avoid suspicion.
Discovery of Bodies
As treasure hunters search for a sunken galleon off the coast of Miami, their radar shows an aberration on the sea floor. Hoping to find the ship and its gold, two scuba divers approach the site.
Their metal detector crackles and they search through the the sand, finding a cleaver. Nearby, they notice a black garbage bag and open it. They are shocked when body parts emerge, and they hastily swim back to the surface. Additional black bags, along with scattered human bones, are in the area.
