Utah Department of Public Safety officials said the semi-was headed southbound on U.S. Highway 189 between Heber and Provo Monday evening, when the truck suddenly jack-knifed, crashed through a guardrail and went into the lake.
The semi’s cab was submerged nose down under the weight of the semi, leaving the driver trapped.
Wasatch Fire District Chief Eric Hales said teams from Wasatch County Search and Rescue and the Utah Department of Public Safety recovered the body of the driver from the cab mid-morning. The semi driver is from Utah, but his name was not immediately released.
Hales said the semi was hauling just under 12,000 gallons of propane, which was breached during when the tank cut through the highway was also damaged, leaking some of its 130 gallons of diesel fuel into the water.
Hales said his team was working closely with the Utah Water Conservancy, which manages the reservoir, with the clean-up.
Hales said two large cranes were at the scene of the crash Tuesday and would be used to haul the semi out of the water.
An investigation of the accident by UHP is ongoing. UDOT anticipates the road will reopen by 9 p.m. Tuesday, May 21.
