MPC, I sent you a pm with my email address.
Thanks
NEDOC, the dock idea is a good one. Would a floating dock work better? Of course, you are adding cost, but getting easier adjustability. (At least in my opinion..)

9 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these.
I think that's about all I should put in my little pond.
