Divers Know What’s Down There at Bear Lake. Does Anyone Else?
Ask a scuba diver where to dive at Bear Lake and they'll tell you about Cisco Beach. Ask them what's down there and they'll tell you about the wreck — a sunken boat resting at around 40 to 70 feet, its exact depth dependent on the lake's annual water elevation. Ask a few more questions and they'll mention "the Car Lot."
The Car Lot is exactly what it sounds like. Decades ago — according to accounts circulating in the Utah diving community — a collection of vehicles was submerged in Bear Lake, reportedly in the 1930s, in a section of the lakebed that has since become an unofficial dive destination. Today those cars sit between 65 and 85 feet of water, depending on the lake level. The wreck of a boat lies nearby, hard to locate in recent years, possibly having slid further down the slope as the lakebed settled beneath it.
For recreational divers, these are curiosities. For environmental stewards, they are a slow-motion crisis.
What Happens When Cars Sit Underwater for Decades
A vehicle submerged for nearly a century is not just an interesting artifact. It is a chemical storage vessel that has been slowly failing. Gasoline residue, motor oil, differential fluid, brake fluid, transmission fluid, coolant — every system on a 1930s automobile contained petroleum products or heavy metal compounds that have been leaching into Bear Lake's sediment for nearly ninety years. Lead-based paint. Asbestos in brake components. Rubber seals and gaskets that have long since dissolved, releasing their chemical compositions into the surrounding water.
No single car destroys a lake. But the Car Lot is not a single car. And Bear Lake is not a sacrifice zone — it is one of Utah's most ecologically sensitive and recreationally vital bodies of water, home to species found nowhere else on earth and relied upon by millions of residents and visitors every year.
The Problem with Treating Wrecks as Features
The diving community's affection for the Bear Lake wrecks is understandable. Artificial reefs and underwater structures attract marine life. They give divers something to navigate toward. They feel like discovery. But calling a collection of sunken 1930s automobiles a "dive site" rather than a pollution source is a reframing that benefits recreation at the expense of ecology.
We are not anti-diving. Quite the opposite — our recovery teams are divers. But we recognize that the presence of fascinating underwater objects does not neutralize their environmental impact. A car is not less toxic because it has been on the bottom for ninety years. The toxicity compounds over time as protective coatings fail and structural integrity collapses.
The Boat Wreck Is Another Story
The submerged boat at Cisco Beach represents a more recent and potentially more acute pollution problem. Fiberglass hulls from mid-to-late 20th century vessels can release styrene and other volatile organic compounds as they degrade. Modern marine engines, even old ones, contain far more synthetic lubricants and refined fuels than their 1930s counterparts. A fiberglass boat with a working fuel system that goes to the bottom of a lake is a different kind of pollution threat than an old steel car body — and it requires a different approach to recovery.
What Fathom Restoration Can Do
We are built for exactly this kind of work. Underwater debris removal in Utah's lakes requires technical dive capability, sonar mapping, surface support logistics, and coordination with state environmental and parks agencies. It requires the patience to work at depth in cold, clear water where visibility reveals everything — including how much work remains to be done.
The Car Lot at Bear Lake has been there for close to a century. Every year it stays is another year of slow contamination in a lake that does not have the ecological buffer to absorb it indefinitely. We are ready to assess, plan, and begin the work of extracting what does not belong on that lakebed.
If you dive Bear Lake and have observed the location or condition of these wrecks, your information is valuable to us. If you want to support the cleanup effort, visit fathomrestoration.org. The cars have been down there long enough.
Fathom Restoration is a Utah nonprofit dedicated to recovering submerged vehicles, vessels, and debris from Utah's lakes and waterways. Donate, volunteer, or report a submerged vehicle at fathomrestoration.org.
