I have a creek that runs around my pond. We had beavers maybe 20 years ago, then they disappeared. They've reappeared over the last couple years and have dammed up the creek pretty good. So good there's algae in a lot of places along the creek. Something I've never seen before. Because of the close proximity to my pond, is it advisable, if possible, to destroy this dam? I kind of want to just for the sake of the creek's health.
