Seen on one of the ponds. The bubbles are from a water spout (out of frame), not a real fountain, that barely erupts from the surface of the pond. In this season, it drives back the duckweed and creates a clear area where bubbles form. Leaves that fall into the clear area are also carried outward to the perimeter of the open area.
