According
to the USACE web site,
This week we
began our annual Submerged Aquatic Vegetation (SAV)
mapping effort. The entire submerged plant community of the lake is
mapped with an intensive program that includes over 700 sites around the
shoreline (grid map attached). The abundance of SAV
at each site (center of each grid cell) is documented and the total number of
acres of each dominant plant species is determined and coverage maps are
developed.
An increase in algal bloom formations is anticipated as nutrient
rich runoff increases with increased rainfall.
