The railroad was pulled up long ago. The majority of the trees there are ash and a couple of water oaks. The railroad bed has been there for over 100 years old with the top 75-100' across and the base is closer to 200' wide. If a tree was windthrown, I would have plenty of space to come in for a repair. I wonder how much these trees draw up in summer? I, luckily, have no cottonwoods and I am cutting most of the willow I find. The pond is not lined, the soil is pretty heavy clay, and was originally made in 1895 and repaired and refilled in the '90s after an unknown amount of time with a breeched dam.
