Lake Okeechobee Conditions Report September 11, 2007:

 

According to the USACE web site, Lake Okeechobee stage is 9.57’ NGVD, which is 0.02’ higher than a week ago and 0.11’ higher than a month ago.  The current stage is 3.73’ lower than it was a year ago and approximately 4’ below its historical average for this time of year.  Reported surface inflows are 1039 cfs compared with 1392 cfs last week.  These values do not include gravity inflows through the S77 (76 cfs) and S308 (not reported) structures.  No surface outflows are reported.

 

Monthly algal bloom monitoring was conducted on the 22nd of August.  Four of the 10 monitoring sites were dry.  An algal bloom was present at 1 of remaining 6 survey locations.  Algal toxins were not detected. 

 

The September submerged-aquatic-vegetation (SAV) survey documented SAV at 80% of the sites sampled.  Several other sites sampled in previous surveys were dry.  Water clarity was excellent at all sites.  Results show that SAV continues to recover following the hurricanes of 2004 and 2005, which removed most of the SAV from the lake.
