The 28th Annual Avalon Harbor Underwater Cleanup is scheduled for Saturday, February 21, 2009. This is an annual dive event held in Avalon Harbor at Catalina Island.  The event was started in the 1970's by the local dive community in an effort to cleanup Avalon Harbor, and this event is the only time diving is permitted there.  The event has grown over the years to become one of the most publicized and popular dive events in Southern California.

Besides offering divers the opportunity to dive in Avalon Harbor, the event brings together a large number of people who share common interests - diving  and Catalina.  Last year more than 520 divers participated in the event.  The proceeds of the Avalon Harbor Underwater Cleanup benefit the Catalina Island Conservancy's Ocean Conservation projects and the Catalina Hyperbaric Chamber.  Catalina Conservancy Divers is a support group of the Catalina Conservancy.  The Catalina Hyperbaric Chamber is a life support recompressions chamber on Catalina that is available to serve the thousands of divers who frequent the Catalina waters.
