Lake Okeechobee Conditions Report December  9, 2008:

According to the USACE web site, Lake Okeechobee stage is 14.16’ NGVD, which is 0.12’ lower than a week ago, 0.53’ lower than a month ago, and 3.98’ higher than it was a year ago.  The current stage is 0.59’ below the historical average for this date, and 0.48’ above the simulated historical average for the current regulation schedule (LORS2008).  Total reported inflows are 179 cfs and include contributions from S65E (168 cfs) and Fisheating Creek (11 cfs).  Total reported outflows are 1517 and include baseflow releases towards the estuaries through the S77 (105 cfs) and S308 (333 cfs), water-supply releases through S351 (386 cfs), S352 (390 cfs), and S354 (291 cfs), and a small volume (12 cfs) to the L8 at Canal Point. 

 

The monthly submerged-aquatic-vegetation (SAV) survey was completed last week and 8 of the 24 sites sampled had plants (compared to 10 of 30 in November).  Vegetation was sparse or very sparse at all 8 sites.  The macroalga Chara was found at 1 site in the south and 1 site in the west.  Two vascular species also were found, Vallisneria (2 sites in the west and 1 in the north) and Ceratophyllum (4 sites in the north).  Water clarity was the same as it was last month with an average secchi depth:total depth ratio of 0.33.
