Let surface drainage run onto a meadow

I know that it is forbidden. I would design it in such a way that you would only think of it if you check during heavy rain... And it is not the neighbor's flower bed, but a cow pasture.

Well, it could have been that, for example, with the owner's permission, the rainwater is also allowed to drain onto neighboring meadows...

Furthermore, what I do and what I think are two different matters... just because I discuss it here doesn't mean I actually implement it that way
