Given that there were "koi" -

(Which turned out to be goldfish when they woke up today) in the largest pond, together with foreign water lilies, I suspect these are also introduced.

Thanks -

for the proposed identification. I'd wondered about Lymnaea stagnalis, but wasn't sure, especially about the size. Perhaps they're siblings not yet fully grown.
If you're right, at least they're native!

I agree

The slender spire relative to the last whorl is characteristic of this species.

Thanks

To both of you. L stagnalis it is!
