Looks great Bob. You didn't seem to encounter too much rock. Not nearly as much as I did! Now you just need a little moisture. Right after you get the seed down. wink
Good luck with the seeding. Just a FYI, don't put the grass matts down below the expected water levels. I did where I thought it would be running in too fast. The grass part of the mat dissolved and the netting was left. It acted as a gill net on my GSH..

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.
