Sunil:
Where the inflow pipe is for the water that comes into the pond in the Spring, I placed 10 tons of 8"-10" rip-rap, and on the other side of the pond there is between 40 and 60 tons of broken concrete, plus between 400 and 500 cinderblocks in another spot, about 50' from the concrete. I released them in the rocky areas, hoping they will have enough places to hide from the LMB and the CC.
