small lake or pond with an aerator running in the center, creating a large spray of water. The water appears slightly murky. A stone walkway with metal railings runs along the near edge of the water. A red life preserver hangs on the railing. On the far side of the water, there's a low stone wall with a walkway behind it, and beyond that, grass and trees. A person on a bicycle rides along the walkway on the far side. The weather seems mild, and the trees have green foliage.
