Buoys on the north side of Heron Lake

Worn hazard buoy near the entrance to the northwestern arm of Heron Lake.

Shallow water extends far from a point of land that projects from the north side of Heron Lake; keels can run aground more than a hundred yards from shore in a lake that has depths of more than two hundred feet.

This is supposed to be a hazard warning buoy for shallow water, but it's about to become a submerged hazard itself.
