Three Oaks Recreation Area was opened in 2013 for SCUBA training ONLY. Instructor or Dive Shop MUST file insurance docs to be able to bring students. It is a good open water training facility and rumors are it will be opened to public for diving in the next couple of years. However 3 Oaks primarily is a Fishing lake and beach so scuba divers are limited to small designated area. Diving area has 4 platforms at about 20-25 ft of water. Visibility usually over 50 Ft.
