YOU ASKED. HERE'S THE ANSWER.

Yes, there are cars at the bottom of Utah's lakes.

Our research places 499 submerged items across 20 Utah lakes and reservoirs: cars, trucks, boats, even aircraft. 226 of them are individually documented, each with a primary source. Most have been down there for decades. Nobody had a plan to bring them up. We're building one.

WHAT'S ACTUALLY DOWN THERE

Cars through the ice. Boats that never came home.

Vehicles that went through winter ice and were written off. Boats that sank at their moorings. Aircraft that ditched and were left where they settled. Recovery was expensive, so most of it simply stayed.

A vehicle that went under in the 1980s is still down there tonight, its fuel tank and fluid lines corroding a little more every winter. Steel gives up slowly. Gaskets don't last forever.

WHY IT MATTERS

Contamination that never stops on its own.

  • Every submerged vehicle and vessel carries motor oil, fuel, coolant, and a lead-acid battery with up to ~18 lbs of lead.
  • Under EPA rules, any oil that causes a film or sheen on the surface of the water is a harmful, reportable discharge (40 CFR Part 110). There is no safe amount.
  • And it persists: USGS documents oil from a 1979 spill near Bemidji, Minnesota still contaminating groundwater more than four decades later.

WHO'S DOING SOMETHING ABOUT IT

The crew building Utah's recovery capability.

Fathom Restoration is a veteran-led Utah 501(c)(3). We wrote the Atlas. Now we're building the state's first dedicated submerged-debris recovery capability: the certifications, the equipment, and the crew it takes to lift a truck off a lake bed and dispose of its fluids properly. First recoveries are targeted for 2027.
