I was worried about disturbing the bottom as well! That's good advice - I have a contact in the DNR that I will reach out to
On a side note, my neighbors have stated the pond used to be 15' feet deeper or more in certain places...now it's mostly 5' to 6' deep on average. I think I'm going to encounter mostly muck. And with the amount of clay I am dealing with in my yard, one would think I'm living on the world's reserve of clay - so I'm hoping I'm good. But better safe than sorry!
