Agree with what's been said, but my first thought was it probably also has a lot do to with the type of tree. Based on the photos you provided, it doesn't look like the hardwoods are terribly close to the dam - and I'd be more concerned with those root systems than that of pine (which also aren't very close). My best guess is you are good to go, but I'm sure there are some experienced folks with this sort of thing that can confirm.
