FISH LAKE, Utah — A search is underway for a 13-year-old boy at Fish Lake in Sevier County.
The Sevier County Sheriff's Office was notified of a capsized boat Friday morning.
According to Sevier County Sheriff Nathan Curtis, a father and son from Cedar City had been fishing with a friend.
At 3:30 a.m., they dropped the friend off and the father and son headed back out to fish some more.
Just before 8:00 a.m. some fishermen could hear someone yelling for help.
They located the father and were able to get him to shore. He was taken to Sevier Valley hospital to be treated for exposure and hypothermia.
Curtis said the boat capsized where the water is about 100 deep.
Around 9 p.m. Sheriff Curtis said "We are actively grid searching the lake right now."
Rescue crews from Sevier County and a dive team from the Utah Highway Patrol-Department of Public Safety are looking for the boy.
The state fire marshal’s office is also on site searching.
Curtis said there have been drownings at Fish Lake before, but not this time of year.
He has been in contact with the boy's father and mother.
"Our expectation is we’ll bring this young man home to his family," Curtis said.
FOX 13 has a crew on scene and will update this story as new information becomes available.
