The stretch of Florida coast from Sebastian down through Fort Pierce isn't called the Treasure Coast as a marketing gimmick. In July 1715, a Spanish treasure fleet hauling gold and silver back to Spain was caught by a hurricane and wrecked along these very shores. Millions in coins and artifacts went to the bottom — and gold from the 1715 fleet still turns up on Treasure Coast beaches after big storms to this day.
So here's the daydream every waterfront buyer on the Indian River Lagoon or near the Fort Pierce Inlet eventually has: if there's a galleon full of gold sitting off my dock, is the treasure mine? The answer is a fascinating collision of riparian rights, state ownership, and centuries-old salvage law — and it's mostly no.
- Your waterfront generally ends at the mean high water line.
- The state owns the submerged bottom — and historic shipwrecks on it.
- You don't automatically own treasure off your dock.
- Salvage is regulated, not finders-keepers.
What Your Waterfront Deed Actually Includes
As with all Florida waterfront, your private ownership generally runs only to the mean high water line. You hold valuable riparian rights — access to the water, a dock, a view — but you do not own the land (or bottom) beyond that line. That distinction, which we cover in our guide on Florida riparian rights and seawalls, is the whole ballgame here: the treasure isn't on your land, because the bottom under the water isn't your land.
The State Owns the Bottom — and the Wreck
Below the mean high water line of navigable waters, the bottom is sovereignty submerged land owned by the State of Florida, held in trust for the public. And it's not just the sand: under the federal Abandoned Shipwreck Act and Florida law, abandoned historic shipwrecks embedded in state submerged lands generally belong to the state, which manages them as archaeological and historical resources. So a 1715-fleet wreck off your dock isn't ownerless treasure waiting for the lucky homeowner — it's a state-owned historic resource sitting on state-owned bottom.

How Salvage Actually Works
Treasure hunting off the Treasure Coast is very real — but it's regulated, not finders-keepers. Recovery of artifacts from historic wrecks on state bottom is done under state authorization (historically, salvage agreements and permits with the state), with the state retaining an interest in what's recovered. Professional salvors operate under these arrangements; a homeowner wading out with a metal detector to claim a galleon does not. Beachcombing for loose coins that have washed onto the dry beach is a different, more permissive situation than excavating a wreck on the submerged bottom — but even there, rules apply.
So What Can a Homeowner Do?
Owning Treasure Coast waterfront is wonderful — just don't buy it believing a sunken galleon comes with the deed. Practically:
- Enjoy the riparian rights you do have — dock, access, view — which are the real value of waterfront.
- Don't excavate the bottom looking for treasure; that's regulated state territory.
- Understand your boundary ends at the water line, not somewhere out in the lagoon.
- Get a survey and title work that make your actual waterfront rights clear.

The Title Lesson Underneath the Romance
The galleon is a great story, but it teaches the same lesson every serious waterfront buyer needs: you own less of the water than you think, and the state owns more. Whether it's a Spanish wreck, the sand added by a storm, or the bottom your dock stands over, the line between private upland and public water is where waterfront title gets interesting. Getting that line surveyed and understood is exactly what protects a buyer — treasure or no treasure.

Frequently Asked Questions
If a shipwreck is off my Florida waterfront, do I own it?
Generally no. Your private ownership runs to the mean high water line; the submerged bottom beyond it is state-owned sovereignty land. Under the federal Abandoned Shipwreck Act and Florida law, abandoned historic shipwrecks embedded in state submerged lands generally belong to the state, not the adjacent homeowner.
Who owns treasure found on the Treasure Coast?
Historic shipwreck material on state-owned submerged bottom is generally owned and managed by the State of Florida as an archaeological and historical resource. Recovery is done under state authorization by permitted salvors, with the state retaining an interest — it is regulated, not finders-keepers.
What does my waterfront deed actually include?
Typically ownership to the mean high water line, plus riparian rights such as access to the water, the right to build a dock, and a view. It does not include the submerged bottom beyond that line or historic wrecks resting on it, which are state-owned.
Can I hunt for treasure off my own dock?
Not by excavating the state-owned bottom. Recovering artifacts from historic wrecks is regulated and done under state authorization by permitted salvors. Beachcombing for loose coins that wash onto the dry beach is a different and more permissive situation, but excavating a wreck is not something a homeowner can do freely.
What is the 1715 Treasure Fleet?
It was a Spanish fleet carrying gold and silver that sank in a 1715 hurricane along Florida's east-central coast, from around Sebastian to Fort Pierce. The disaster gave the Treasure Coast its name, and coins from the fleet still occasionally wash up on the beaches after storms.
Why does this matter when buying waterfront?
Because it illustrates that a waterfront owner generally owns less of the water than they assume — ownership stops at the water line, and the state owns the bottom (and wrecks on it). A survey and title work that clarify your actual riparian boundary are what protect you as a buyer.
