Lake
Okeechobee Conditions Report December 11, 2007:
According
to the USACE web site, Lake
Okeechobee stage is 10.18’ NGVD,
which is 0.05’ lower than a week ago and 0.15’ lower than a month
ago. The current stage is 1.90’ lower than it was a year ago and
4.68’ below its historical average for this time of year. Total
reported surface inflows are similar to last week and are limited to flows of
280 cfs from the Kissimmee River.
Total outflows are not reported due to missing data from the S308 and the S352.
The
monthly submerged-aquatic-vegetation (SAV) survey was
completed last week. The macroalga Chara remains the dominant SAV
species and was found at 20 of the 33 sites sampled. This distribution is
similar to that in November, although densities appear to be declining at some
locations. One species of vascular SAV, Vallisneria americana,
continues to be present in low density at a few sites near the northern and
western shoreline. Water clarity in nearshore
areas remains favorable for continued SAV growth (SD:TD ratio > 0.5).
