They make my farm better. Somebody does have to go out regularly and take apart dams that threaten the road, but it is not hard to do if you never let the dams get high. If they do manage to back up a lot of water they get a lot more productive.
I looked into ‘beaver deceivers’ and similar things and decided to keep with a system that works. We have a tenant who does it for us, he has a great story to tell when he goes to any ‘new age’ gathering.
