Wetland WA is a bottomland forested wetland with a moderately dense layer of shrubs and river cane. Trees
within the wetland were heavily buttressed and numerous bald-cypress knees were observed. Standing water
was observed throughout the wetland. A man-made upland berm was present within the wetland.

Standing water was observed throughout WA. Numerous buttressed trees and bald-cypress knees
were also observed within WA. The water table was present at 5" at the wetland data point and
saturation was present at 2".
