According
to the USACE web site,
The
monthly submerged-aquatic-vegetation (SAV) survey was
completed last week. Water clarity was generally conducive to plant
growth with secchi depths greater than 50% of total
depths at 30 of the 31 sites sampled. The macroalga
Chara remains the dominant SAV
species and was found at 10 of the 30 sites (6 of the 10 sites were in the
south end of the lake). One species of vascular SAV,
Vallisneria
The
algal bloom reported to be developing at several locations across the lake has
disappeared and field reports from last week indicate that it has not
reformed. Cyanobacterial toxin data were
collected on May 1 as the bloom dissipated. A microcystin
level of 1.2 ppb was reported at the Pahokee Marina, and other sites had toxin
levels below detection (<0.2 ppb). Chlorophyll data from the bloom
sampling are not yet available.
A
wildfire continues to burn in the littoral zone in the southwest corner of the
lake. Roughly 9000-10,000 acres have now burned. The fire is 50%
contained and its rate of spread has slowed. However, burning muck will
continue to be an issue until the area experiences significant rainfall.
