Morrill County Attorney Travis Rodak says Brett Golden was pronounced dead Wednesday evening at Bridgeport State Recreation Area.
Rodak says Golden's car hit a tree before entering a small lake near the beach area of the recreation area's main lake. A couple of campers spotted the car, which was almost totally submerged. Golden's body was found inside.
It's unclear when the accident occurred. Golden was last seen leaving his home in the rural community of Redington around 9 a.m. Wednesday.
An autopsy has been ordered.
