______________________________________________________________________________ (I) - Flows preceeded by "I" signify an instantaneous flow computed from the single value reported for the day ______________________________________________________________________________ * On 11 May 1999, Lake Okeechobee Elevation was switched from Instantaneous 2400 value to an average-daily lake average. On 14 Mar 2001, due to the isolation of various gages within the standard 10 stations, the average of the interior 4 station gages was used as the Lake Okeechobee Elevation. On 05 November 2010, Lake Okeechobee Elevation was switched to a 9 gage mix of interior and edge gages to obtain a more reliable representation of the lake level. On 09 May 2011, Lake Okeechobee Elevation was switched to a 8 gage mix of interior and edge gages to obtain a more reliable representation of the lake level due to isolation of S135 from low lake levels. Today Lake Okechobee elevation is determined from the 4 Int & 4 Edge stations ++ For more information see the Jacksonville District Navigation website at http://www.saj.usace.army.mil/ $ For information regarding Lake Okeechobee Service Area water restrictions please refer to www.sfwmd.gov ______________________________________________________________________________ Report Generated 29OCT2026 @ 14:15 ** Preliminary Data - Subject to Revision **
