In front of the Sovereign House offices on Vision Park in Histon that I work in (as of 2019) there is a gentle pond. It has a fountain that is sometimes spurting forth, water lilies that in their season squat on the surface, and ducks that keep on trying to rear ducklings but keep losing them to herons and other predators. Watching over the pond there is a coffee and sandwich bar d:licious which I patronise once a week.
In early 2019 they (whoever they are in this case) decided that this pond needed a makeover. This was a radical makeover which involved removing the fish and terrapins, digging the pond right out, laying new liners, reseeding the surrounding green. As something to put on my website here is a photographic record of the process.
