That is from some friends of mine who have tried to get in there. I don't have a depth finder on my boat as I only draw 2'9" with the board up. Years ago I went in & out on a MacGregor 65 which draws 8'1". We couldn't stay on the right side of the channel coming in as we did touch bottom. On the left or Soouth side we made it in although many people were not pleased as it was a weekend. I did try to make some soundings a couple years ago & as I rememmber the shallow part is just before the outer bouys to the second set & then it dropped off. I will try to check it again this spring as soon as the ice is out. I tried to get out to the lake yesterday but there was too much ice but I needed some type of boat ride even if it was only in the Clinton River.
