Cleaning up what since just last week is part of the newly designated 12th Underwater Preserve in the state, divers from around the area participated in an annual clean up organized by the Traverse Area Association of Realtors Environmental Committee, the Watershed Center, Great Lakes Scuba and Scuba North. For the past three years, the Grand Traverse Bay Underwater Preserve has worked to create the preserve, whose designation will be a boon for diving tourism and also boosts historical and archeological research.
