reminds me of a comment from my nearest and dearest when we were boating up the Thames. Late one evening she saw some ducks in a lock and said caringly - "Oh look, those poor ducks will be stuck in the lock all night"

If the pond is being rebuilt to modern standards perhaps they could put a few solar powered patio lights to designate a landing strip in the pond at night

isn't the internet wonderful - here it is John - ducks crossing sign
