Faced with shrinking budgets, the U.S. Army Corps of Engineers is looking at whether it can continue to operate all its recreational areas, including parks. “The bottom line is if a park’s not worth it, we’re either going to lease it out, close it or ... divest ourselves of it,” said Tim Rainey, operations project manager at Lake Lanier. He said Lake Lanier is looking at a “managing partnership” idea to keep open parks that might otherwise close.
