So my pond was overrun with muskrats. Now all the muskrats are gone and I’m left with damage I’ve probably lost at least 5 feet of water in eight years I’ve been here. I do plan on renting a mini excavator. My question is has anybody ever dug up their Burroughs? How far back or how deep should I go to make sure that they are properly collapsed? I just want my pond to start holding water again. Just try not to create a bigger mess than what I’ve already got on my hands. Thanks.
