Pond Boss Forums POND CONSTRUCTION Building a dam Leaving trees on a dam ?

I left one tree, about 10" dbh, way down at the end of where we got rid of excess dirt below the dam at my new pond. It had fill over about 60% of the root area, with the rest of the root area left at the original elevation. There was a small ditch (maybe 2' wide, 4' deep) dug in the root area as well, to bury a water line to a freezeout hydrant just past the tree. That tree was fine for this last year, the first after the excavating.
