I asked Bob about this on his Wednesday night Facebook Live. He said he wrote about this in the November/December issue of Pond Boss magazine. Also he said that it is viable management tool as long as you expect the water level to rise within 5-6 months. It is good for concentration the fish and weed management.
Thanks. I'm gonna get a pith helmet & machete to see if I can get to the structure.
