No excavator needed in the pond, but I did put two loader buckets full of 6"x12" crushed limestone on the water side of the dam yesterday.

I'd been needing to get back on that project for awhile, but the brakes were out on my loader tractor so not safe to attempt. lol
I got that problem corrected a couple weeks ago and I'm back in business. Probably have another half dozen scoops of cobble
on the pile that still need to go into the pond. It will be nice to have that job finished.
