Yeah you buddy (liquidsquid) were part of the problem. I showed her your pond and your big rocks you had posted in your thread. She wanted one.
With the water low in the pond this summer, grandson and I were able to dig a good hole just above the then water line down deep enough into the solid compacted clay of the dam that I THINK this one will stay in place. But no guarantees. We poured a pretty good foundation of concrete and let it set up before starting laying the support rocks in. Water actually runs underneath this rock being supported by smaller rocks then the foundation.
Sorry to hear yours did not stay in place. At least you have fish habitat! Maybe you will catch a lunker beside one of those big rocks on the bottom some day.
