 In this photo a backhoe was being use to remove a deck from behind a house when it all went wrong. Apparently the backhoe driver drove the backhoe into the pool by mistake while they were working. That looks to be a pretty deep pool as even the tires of the backhoe are under water. I've seen other photos like this where cars drove through a fence into the pool but I've never seen a backhoe submerged in a pool like this before. They probably had to bring a crane it to remove the backhoe so that it didn't destroy the sides of the pool while they were pulling it out.
