I wondered the same thing. It's not old, this whole area is brand spanking new - I believe the location in which she was found might even still be under construction. Google's 3D globe data doesn't show either that road or that pond even existing. There also isn't street-view data, the street-view of that area ends at barrels blocking Dowden at Story-Time, the intersection immediately before the pond she was found in but here's a street-view of a similar structure on the previous pond. I'm still not 100% sure what its purpose is but it appears to be a concave cement pad that extends into the pond and surrounded by posts and fencing. Maybe some kind of a drain that filters out large debris. The one on the pond she was found in appears to be under construction in the aerial view which is tagged from 2020 so a person might have accidentally driven into it thinking they were just going to drive around to the back side of the pond, especially if they were intoxicated.
