***  NOTE: 1)  Discharge from (0700-2100) is computed using Spillway and Sector
               Gate Discharges from 0700 hrs to 2100 hrs.
           2)  Discharge (ALL DAY) is computed using Spillway, Sector Gate and
               Lockages Discharges from 0015 hrs to 2400 hrs.

(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
