The sheriff's office says Jesse Sebade, 21, of Fall City, was visiting for a family reunion and camping with friends along the lake.
The Yakima Herald-Republic reported that he had been drinking beer and listening to music in his pickup truck about 3 a.m. when a friend encouraged him to go to sleep.
A short time later friends heard the truck roll down a steep embankment into the water. It had sunk by the time they swam out and tried to find him.
The sheriff's office said the truck and body were found about 45 feet from shore in 30 feet of water.
