Took down two dead trees at the edge of the pond, each between 24" and 28" DBH. Needed a rope and a tractor to make sure they didn't fall into the pond. Now pecking at digging a 20' x 20'+ x 4' deep pond to see if SoilFloc will work at sealing sand if it's incorporated into the sand bottom first. If it works, then I will dig a couple of 1/20 ac ponds and use it to seal them.
