I seriously cannot tell if this is a pool or a lake. I guess that speaks volumes to how well designed this backyard landscape is. They have managed to build a setting that overlooks this crystal clear body of water, and it can go both ways. If this is a pool, then they have managed to create a natural looking setting using bushes, flowers and stone as part of the visual pallet. If it is a natural body of water, then they have the perfect backdrop to their backyard landscape design. This is not an easy balance to strike, and the landscaper has definitely pulled it off here.
