I actually have a pile sitting beside the pond to add more. That was put in to stop shore line erosion and I will add quite a bit more even higher up the bank now that the water will be higher. I have added piles of that size rock, some rock piles of fist size to half football size rock, and some road rock (ab3 we call it, 1" with fines all the way to ag lime) piles in the water for the fish.
So the rock you see will be for the fish and crawdads if any ever establish or if I can get some bought to add. They say crayfish are really good for SMB ponds and rock piles are really good for crayfish.
The fish nest pictured (with a RES on the nest) is made in some ab3 and larger rocks are just to the left in the picture.
I like rock piles and have added quite a few in both this pond and in my main 3 acre pond recently. Probably about 50 ton worth.
