Willard bay depth map?

[Tin-Can]

Just one more area to be aware of.  At the area marked in blue on included post, several years ago there was a leak under the dike wall. The DNR had a coffer dam built there so they could reduce the main water level low enough to allow repair to the leak .  The rocks are still there. When the water level is up as it has been since last year, and will probably be again this year, those rocks aren't an issue unless you are in a larger, deep draft boat. But when / if the water level drops, they can be a hazard.  The DNR had warning buoys around them for awhile, but I haven't seen them the past couple years. 
I've seen several smaller boats in that general area and at some points you can see weed growth just above the surface.
