Johnson Ng, 39, was from Daly City.
Deputies said he is the missing boater who fell into the water near Antioch Bridge on April 28. They found him at 2:11 p.m. Saturday after receiving reports of a body on the levee at False River near the San Joaquin River.
Initial reports from deputies said two men were on a boat trying to set an anchor to start fishing when a wake came along.
The wake hit the boat, the men fell off and they did not have life jackets on, according to sheriff's officials. A passing boat rescued one of the men.
The Contra Costa County coroner's office will conduct an autopsy to determine the cause of Ng's death.
