Bellevue police and the King County medical examiner are responding to the report of a body floating in Phantom Lake.
Police say it is unclear if it is related to the missing person case in late June, when a farther disappeared after a raft capsized.
Crews pulled a 5-year-old boy from the water the night of June 20, but his 37-year-old father was not found.
Authorities said the boy and his father were on the lake fishing when something went wrong and their raft capsized.
The boy had a life jacket on and swam towards firefighters, who then pulled him from the water. The boy was taken to the hospital to be checked out.
His father was not wearing a life jacket.
"Just a few feet below the surface, there's a temperature change, and had our boater gone to that depth, it could have put him in cold water shock," said Bellevue Police Officer Tory Mangione in June.
