Under the C&SF project, the Corps establishes a regulation schedule for Lake Okeechobee.  This regulation schedule guides the Corps in its management of the lake for flood control, water supply, and protection of the natural system. Prior to LORS there were several lake regulation schedules.  Most recently they included the Water Supply and Environment (WSE) schedule from 2000-2008 and Run 25 from 1994-2000.  LORS remains in effect and sets the lake levels between 12.5 and 15.5 feet above mean sea level.
