The family of a Forsyth County man who went missing a week ago while boating on Lake Lanier hasn’t given up the search.

Authorities have said Stephen Bryk, 62, was last seen about 9 a.m. Aug. 24.

His wife reported him missing later that afternoon when he didn’t return from an outing alone on the lake.

His pontoon boat was found drifting in the water between Shady Grove Campground and Young Deer Park in northeastern Forsyth.

Bryk’s son, Jeff, said volunteers and friends are still trying to find him.

"There’s still a full search going on and it will continue for about five more days until we’ve exhausted the proper amount of time to look for the body," he said Monday.

"This has been incredibly difficult … Our neighbors and friends are still trying to help and search for the body."

Public safety officials have said it appears the elder Bryk had some engine trouble and got into the water to work on the boat.

However, they were unable to determine where that occurred, which hampered the search.

They couldn’t put divers in the water because they didn’t know where to look.

The Forsyth County Fire Department and Sheriff’s Office suspended search efforts late last week.

Spokeswoman Melissa Cummings said rangers with the Georgia Department of Natural Resources continue to patrol several times a day in the area near the mouth of Young Deer Creek.

Fire Division Chief Kevin Wallace has said it was not uncommon for Bryk to go out alone on his boat and that his wife said the retired military serviceman was a good swimmer.

Wallace said the area was broken down into grids and groups searched the surface of the water, shorelines and islands nearby.
