______________________________________________________________________________ (I) - Flows preceeded by "I" signify an instantaneous flow computed from the single value reported for the day ______________________________________________________________________________ * As of 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, we began using the average of the interior 4 station gages as the official Lake Okeechobee Elevation. * On 16 April 2007, Lake Okeechobee Elevation was switched to a 8 gage mixture of interior and exterior gages due to wind effects on Lake O (When the 4 station gages are not working the 10 station elevation is used) Today Lake Okechobee elevation is determined from the 4 interior stations ++ For more information see the Jacksonville District Navigation website at http://www.saj.usace.army.mil/hydroSurvey/hydro.htm $ For information regarding Lake Okeechobee Service Area water restrictions please refer to www.sfwmd.gov ______________________________________________________________________________ Report Generated 03NOV2008 @ 14:15 ** Preliminary Data - Subject to Revision **
