According
to the USACE web site,
In
December, 24 of the 27 water quality sampling sites had sufficient water for
sampling. Preliminary lakewide, TP averaged 97 ppb and TSS
averaged 21 mg/L. These concentrations are lower than those measured in
November. Preliminary average TP at nearshore sites decreased from 80 ppb in November to 54 ppb
in December and TSS decreased 19 mg/L to 10.5 mg/L.
The
monthly submerged-aquatic-vegetation (SAV) survey was
completed last week. The macroalga Chara remains the dominant SAV
species and was found at 12 of the 24 sites sampled. This distribution is
lower than that reported in November, with slight reductions in the density of Chara despite continued good to excellent
water clarity (secchi depths 50-100% of total
depths). One species of vascular SAV, Vallisneria
