The mission of the Lake Patrol is first and foremost the safety of the public, who use the lake and adjacent parks and beaches. The Lake Patrol officers also assist stranded boaters by towing them to shore and utilize Lake Elsinore Marine Search and Rescue (L.E.M.S.A.R) volunteers whenever possible in assisting the public.
L.E.M.S.A.R. augments the Lake Elsinore Police Department's Lake Patrol operations. These volunteers patrol the lake, and they are the eyes and ears assisting Lake Patrol personnel. They are trained in emergency First Aid and CPR, and they must complete the United States Coast Guard's auxiliary boating and safety course.
