Breached the pond dam by digging a trench and drained the water in under an hour. The water was contaminated from cattle and horses having gained access to the pond and the shoreline was badly eroded from the livestock presence. After the farm pond has time to dry, we will use the excavator, John Deere skid steer, CAT bull dozer and the articulated dump truck to dig and load the pond sludge and haul and dump it into one of the pastures.
