U.S. Army Corps of Engineers, Fort Worth District Park Rangers Ryley Rosenbusch, left, and Alex Klepac rescued a teenager at Stillhouse Hollow Lake after the teen attempted to swim to an island 1,000 yards from the shore without a life jacket. They found the teen clinging to a semi-submerged piece of driftwood. The teen was badly sunburned and completely exhausted from his ordeal. But overall, the teen was none the worse for wear.
