A subdivision pond, land was cleared in 2008 via Google Earth, appears to be mostly Oaks on the back levee of pond. Land behind pond is 60 acres of protected wetlands with oaks, willow trees and cypress trees. When I did my 16 in 1 water test strips, it did show some type of acid, cyrunic? at 400 ppm? Oak trees are losing their leaves, pretty heavy amount falling in the pond. Thank you for your input ewest!
