Pond Boss Forums POND CONSTRUCTION Soil questions Pond Mission Impossible?

I've noticed that the ducks seem to like pecking at the pond edge/bank, while floating on the water. The mallard especially seems to like poking its bill under the long grass that hangs down for the bank. From what I can tell, a very small part of the bank has collapsed into the pond as a consequence.

That was enough to make me test Chevy, the robotic lawn mower. There a guide wire around the pond and if there's too much bank collapse, that puts the wire too close to the water and Chevy in danger of tumbling into the water. That would not be good!

I pointed him straight at the pond where the bank seemed to have collapsed, to see how he'd go. He stopped well clear of the bank and reversed away, but it's something I need to keep an eye on.
