Pond dismantling ends in garden fiasco

Now a stupid question, where is the water supposed to go?

Shouldn't you think about that beforehand? If the pond is "dismantled," of course the liner has to be removed as well. That way you always have a water collection point without significant infiltration. I would make the best of it and create a swamp bed.

Oh dear, who didn’t think that through quite fully? How much foil is still underneath?

Best possible but not complete I would now say only fragments have remained and hopefully it is noted stabbed?

The pond liner was removed as best as possible (but not completely)

What exactly does that mean? Please upload some photos. Is this now a functioning pond that was only refilled, or are there really only small scraps of the liner left. Apart from that, the ground beneath the old pond has of course been massively compressed over the years. Whether and how water seeps there will be the next exciting question.

Fence around the pond would probably have been more cost-effective... but above all more relaxed.... considering what one reads and possibly still awaits you in the future. Well, whatever... now you have to make the best of it and find a solution.

Images and/or further information would be helpful.

About three years ago I filled in a pond of approximately 10 sqm. First I skimmed everything off, emptied it, removed the liner, and filled it up exclusively with soil (and hornmeal for biodiversity). Even today, when I stand on the former pond area for a longer time, the ground under my heel sinks faster than on the rest of the lawn. However, no puddles form, and if they do, you can open the deepest turf layer, remove it, fill the hole, and then put the turf back on. Such things take time.

Many greetings
