Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Can I Use Pond Sludge to Add / Fill In Shoreline?

My DNR contact confirmed shoving a stick into the muck as well - until I hit the original clay bottom.
He also mentioned late September/October for the excavator so I do not cause an oxygen issue - as I would want to wait until the water temp drops. I recently installed an aerator / diffuser system into the pond that runs 24/7, so I think I will be ok, but I will definitely wait for late September just to make sure.
