Note: Mooring, anchoring and diving at any of the sites is at your own risk. The SWMUP maintains buoys at some of the sites, but there is no guarantee it will be in place when you arrive. Visibility can range from 0-80+ feet, depending on depth and weather conditions.

Please check our Facebook page at for the latest condition updates. The SWMUP is working to promote and develop more sites though side scan searches and intentional vessel sinkings.
