Lake Okeechobee Conditions Report November 13, 2007:

 

According to the USACE web site, Lake Okeechobee stage is 10.33’ NGVD, which is 0.04’ lower than a week ago and 0.23’ higher than a month ago.  The current stage is 2.21’ lower than it was a year ago and remains almost 5’ below its historical average for this time of year.  Total reported surface inflows are down from last week due to declining flow from the Kissmmee River (<250 cfs).  Inflows of 685 cfs are entering from the L8 at Canal Point.  Outflows of 408 cfs are reported at the S135 culverts, but these values appear to be in error. 

 

Continued high winds prevented completion of the November submerged-aquatic-vegetation (SAV) survey last week and conditions on the lake remain turbid.  In the pelagic zone, average TSS increased from 29.9 mg/L in September to 81.1 mg/L in October and average TP increased from 121 ppb to 222 ppb.  A more modest increase in TSS was documented for nearshore sites (5 mg/L in September and 6.5 mg/L in October) and average TP was 41 ppb during both months.
